I thought about playing a drinking game, taking a drink every time you said trusses, then remembered I like living. Great video!
Thanks! You've got to be careful playing drinking games with the Build Show. I have a very limited vocabulary, and once my mind locks onto a word, you better get ready to hear it...a lot. A safer way to play is "How many times does he use a synonym for "cool"", but it would probably be pretty boring.

As a firefighter I have to warn you about those nailplate fasteners, they tend to rattle loose during construction, or through termal stress across seasons. Then when there is a fire they will start popping out and the entire construction can collapse as fast as 15 minutes. Because of that, this type of construction has actually been outlawed in the city by our fire inspector.
Patrick, plywood and/or OSB would be better? Would any of them resist a little more in a fire?
@@avilabra The problem is not the wood, it's the metal plates that connect the beams.
There is not a lot of mechanical connection, especially in the lateral direction. The "nails" are basically just metal spurs that are bend out of the plate.
@@patrickkeller2193 the fire resistance of the plates are a serious concern to me and some say they “fix” the problem using pieces of plywood and nails - and that the nails would resist better to the fire, but they conduct heat even if they are totally inside the trusses. Than it seems to me that there’s no solution besides avoiding trusses that demand metal components in their core, and go for bigger timber and connected only in their ends. Would you agree with that, Patrick?
@@avilabra That fix would actually help a lot. The fire resistance of the materials themselves is not even the problem. Burning through the beams or melting the metal components actually takes much more heat and time. The problem with these one piece nailplates is that they are simply not very secure and can easily slip out and then you are left with free-floating beams. Anything that keeps the plates tightly attached would greatly increase the fire resistance.
That said it is better to avoid nailpates in the first place in favour of traditional carpentry joints and metal fasteners with screws. Might be more expensive and slower, but much safer.
@@patrickkeller2193 and this is why I want to incorporate a fire sprinkler system when I build my home. Why they are only in apartment complexes is crazy, the piping is not crazy and you can catch rain water for the reservoir for the standby water!
super interesting!! i’m shifting career paths into the framing and truss industry, and i wanted to make sure i had some basic knowledge of the product! thanks for the help
Same here! How is it going?
Man after the Swiss/German series, this thing looks like it's made out of toothpicks.
No snow pressure I guess.. We have to add a load of 3-6kN/m2 to the calculation which makes a huge difference.
@@erik....
Only in the northern most states will you be getting that much snow. Most of the US population will not see more than 30 psf (1.5 kn/m2of snow (not including drift))
But these are used even at 6kn/m2. Obviously they will beef them up. This is recorded in a southern state with no snow load. 6kn/m2 of snow will only be seen in like Alaska, Maine and some mountainous regions.
@@Crazylalalalala The same methods of building are used in the northwest states and we get tons of snow. Probably just slightly beefier trusses in comparison to what is used in the southern states, as im not aware of the standards there. But to say these look like toothpicks is ridiculous, more so that the swiss builders love to waste materials by building "less with more". Solid wood walls with no insulation and solid wood floors 10+ inches thick are just laughable to look at. Complete waste of materials with no regard to efficiency while providing no benefit except for "sound proofing" at the cost of ultra high price, excessive unnecessary weight, and intensive labor.
@Colin Stuart _ Wow! I guess one should be a "European" to be a true asshole.

I work at a Builders First Plant. Exact same set up. It’s awesome
Been designing trusses for 20+ years. Done residential and commercial. I currently work for one of if not THE largest component manufacturers in the industry. I can say without hesitation that the truss designer is THE most important part of the process yet is the least paid. I know because I've worked for 3 companies in my journey upward. It's a shame because we take on so many tasks and have to constantly learn new codes and software. Yet all the salesmen do is forward emails and they make twice what we do. I love what I do, I really do. I just wish I was paid accordingly. I can design a floor and roof for a $900,000 home and I'm paid the same as the guy who replaced your tires on your car. Is that fair?
So be a salesman.

Real good video. Going to use it for my construction students.
Jordan should do more videos!
I love these videos man. Thank you!
I have to wonder what the addition of a thick bodied adhesive to the joints would do for strength and long term compliance to spec?
I liked the EU Segments.

Did Mitek choose those truss plates, or did the truss plates choose Mitek?
The thing that hurt me badly was ruclips.net/video/qcNqN5JfgLg/видео.html hammering spiked plates... whilist having such modern solutions... and not using hydraulic press to make it more sleek and for sure make join stronger.
So what's Wilson lumbers connection with Mitek?
Which way is it pressing?
Lazer tables are better.
Heck yeah I work at Builders first source in Duluth we covered the hell up the damn hammering gets old what y'all paying over there in Huntsville got hammer will travel lol hell ya we have all three of the ol saws and the laser shows exactly where the plate should go
I work at builders first source in milton. We get $14 an hour and daily bonuses depending on if we hit at least 6,000ft a day.
But..but... I thought that the floor was made out of floor!
And you know its not properly joined or actually strong enough by the cheap metal plates slapped over everything.
That is why they have walls in a home bare the weight . a open room no walls they use longer straps and use a king truss . been building homes and garages for 30 years , they do the job . snow load in the north they know what lumber you need and type of truss . I still build rafters and truss on the job . for small homes 2000 sq foot . over 2000 sq foot it is cheaper to order them . them cheap plates work , or 1/2 plywood has the same strength
@@JCcanU The interior walls are not usually load bearing in a truss structure. There's no way 1/2 in plywood joins the truss members stronger than the metal plates no possible.
@@DaveMcLain Few studies have investigated the effect of in-service
conditions on the performance of trussed rafters. Luxford
(1958) investigated the effect of changes in relative
humidity on the strength and rigidity of trussed rafters
with nail-glued joints and nailed joints. Both types of
trussed rafters had ample strength and stiffness after
exposure for normal service conditions, but nail-glued
trussed rafters were considerably stiffer and stronger than
the nailed trussed rafters
If you ever had to remove those "cheap metal plates" from trusses once they're pressed in, your opinion might change. In my experience, they're very tough and extremely difficult to remove from the wood. The stuff is all engineered to work.
Ending was weak, needed to accentuate the last 4 words like a boxing match announcer
This was a great video but I don't know, he doesn't say the line the way Matt does. Kid's gotta punch it up a bit.
Woodprix scripts contain most of the woodworking plans you can find.
It's bad, because dey took rrrrr jubbs! tookaderr!
That really told us nothing 😒
Though it is very economical to build and utilize these truss plates, are dangerous. Structure fires happen and when the structure is built with the metal plates and subject to the heat of the fire. This is where the danger lies. When subjected to the heat 500-1000 degrees these plates soften and pop out from the wood thus weakening the structure. As a firefighter and investigator I have seen this first hand. Not a big fan of the metal plates. Would be nice to see something devised that meets the needs of builders but all so for those engaging in life saving and property conservation when under fire conditions. Premature failure and collapse causes death and injury every year to fire fighters and occupants.
Just an opinion from the forgotten ones, when it comes to design and build.
I wanted to compliment your videographer and gaffer for the lovely lighting on Jordan in the truss yard. Are there Construction Video Oscars?-this deserves an award.
Agreed! Jordan and Joey killed this one
The colors are definitely great! The whole video looks like it has really high production value.

Thanks guys.
YESSS!! So glad you appreciate the quality. Joey is a one man production team. He shoots, he lights, he records audio, he edits, and he posts! We couldn't do it without him and he does great work.
Got some trusses for my garage recently. They work but aren't pretty. They look like the worst reject lumber was selected to make them.

Economical? Are you crazy? Here in Miami Dade they start at around $20000 for pre-engineered trusses. I absolutely could build trusses for less than that.
but what you build...would it be engineered and sealed by an engineer with in house and 3rd party inspection??? uh, NO
The top and bottom chords are not only in tension or compression. They have uniform loads from the roof above and the attic/ceiling below, so they're also in bending and shear between the node points. They would be purely in tension or compression if the loads were only applied at the nodes, which is a traditional truss configuration.
I absolutely adored the way you spoke. You know your subject for sure, but the fluency, the selection of words, the intonation, is a natural gift. May you flourish ever more. Thank you!
I am a former trussman from Colorado. Wow...Mytech advancements of tech...very cool...but what is the initial costs of setup???thx....00
I’m wondering how a manufacturing company is started.
As a person who builds trusses, I wish our shop was like this. We set every jig by hand with boards and metal angles, we put all the boards in and beat the plates down then flip them out ourselves on to the rollers, tack the plates on then send it through the press. It’s crazy to see it done like this
Same thing here
Less heavy lifting, but do you want to work at feet all day?
be the change, sell the efficency
This place is about a mile from my house. Did not realize how high tech it is. Nice to know more about what is in my back yard.
I use to Build trusses, The pins or jig wasn't that hard and didn't take much time to setup but great ideal, indeed. We had automatic stacker also. What's going on here is low paid workers that don't know how to read a ruler or can't speak English. I wouldn't suggest anyone buy a from company because your going to get low quality truss at the end of day. Just my opinion from what seen on the video. It's not that hard to make your own, if your just doing it for yourself.
I have these in my 40 year old double wide, opposite of your high end. They still are holding up but do show some issues of the metal fatigue, wavy, which has them pulling out a bit. Since tangs are getting a little sloppy I tried to press them back in but metal memory pulled them back to where they were. I went through with plywood to create a clamp holding them were they are strongest. They had not failed but would have issues in wind (hurricanes) or another ten years (50). Still not bad for a 100 grand house , in a high end house I would not like this. Locking systems should be improved a bit . Just saying my idea is a house should last 500 years .....
this video sucked
I've seen other (older?) truss systems where the metal plates - also known as gang nails - are instead larger plywood squares traditionally nailed into the truss members to do the same thing. You can do that, too.
Matt, i love your videos. I live in south Texas so I apply a lot of the same solutions you present.
But I think Jordan has the tension, compression description wrong. Start with a 3 piece gable configuration, two angled top chords and one horizontal bottom chord to make a triangle as you see on the outside of the truss shown. Clearly the shorter angled top pieces are in compression, and the bottom horizontal piece is in tension to keep the roof from flattening out. Jordan is correct to here.
The longest piece of the trio is the bottom, which will try and sag. Add one vertical tension chord from the center of the bottom to the peak. This will prevent bottom sag by pulling up and it increases the compression on the top chords which also increases the tension on the bottom chord.
The next longest pieces are the angled top chords along the roof deck. To prevent these from sagging, you can put a diagonal compression member from the center of the top chords to meet at the center of bottom chord. These diagonal members increases the tension on the vertical centerline chord which increases the loading as described previously.
The next longest part to sag is either side of center of the bottom chord. You can counter this with two vertical tension chords at the middle of the half spans, or at one quartet of the length from the ends. The tension on this short vertical chord will increase the compression on the bottom portions of the top chord and the diagonal compression chords meeting at the centerline, and so on.
Jordan is looking at the bottom chord like it’s a big beam taking vertical loads from vertical chords.
So basically the diagonal pieces on the interior of the gable configuration will be in compression and the vertical pieces will be in tension. The right side has a short vertical member where it looks like it’s a loading point or wall support position.
The tail end of the truss at the roof drip edge will be reversed in forces. The top will be in tension and horizontal chord part will be in compression. The left side does not have the extension beyond the wall support point.
If you look at an end gable structure with a wall under its entirety, then it will have vertical studs all under compression. Supported the entire length by a wall underneath.
Best regards, Henry
Hmmmm, interesting. I am a truss designer. I use the same software. He summed it up pretty well but there is so much more to it.
Pretty sure these guys measured, cut and delivered my roof in Cook Springs AL., in 2003-4. It was a "Prairie style" hipped roof on the house with two ridges. I was using a 3D program for the design, and they had something compatible that made it drop together like a play toy.
just got to go on a tour of a truss factory two weeks ago.. watching the 6 head saw machine.. amazing.. then watching the guy tacking the the trusses.. 5 minutes for 45 foot long truss then run down the line press down the plates. The machine is so heavy that runs down the line.. if it hits a hammer that was inadvertently left on the line.. POOF one claw removed
Good simple explanation. However, the forces in the webs were stated opposite of what they really are. The kingpost (the vertical member in the center) would actually be in tension whereas it supports the bottom chord and keeps it from deflecting. Then the 2 angled struts that rise up from the bottom of the kingpost are in compression whereas they support the top chord and keep it from deflecting. Then the outer vertical members are in tension similar to the kingpost. Great video though!
Mitek Blows! Customer Service is terrible. Alpine ITW is the OG and is way better in all categories period.
I had simple trusses built for a 24 by 24 garage with a 4-12 pitch. They were not symmetrical and off by an inch and a half. Maybe I'm picky but I think they could have easily made them correct and just didn't. I had to flip them around to make them lineup
Why is there no shear force and bending moment in truss? And what happens if we apply force in between chord rather than applying force at joint?
One thing bothers me from these truss system you waste all the attic area with a lot of 2x4s
They can also do storage trusses designed for a center open space.
@@buildshow Storage trusses with that many different rood angles, is every room going to have their own separate attic storage?
@@2awesome292 Storage truss utilities higher area where you can move easier.
If you fill your whole attic with stuff you simply have too much stuff.
the big lie , its cheaper to make them yourself , they charge more in ireland for factory trusses ... The man makes the money
I make trusses but with more work into it, all wood is cut with a table saw and a chopsaw for short stuff, rather than a rolling table we use pedestals and a free moving 25 tonne press
Is it weird that my favorite part of this is the software?
No, this is really impressive software. There's gotta be relatively complex infrastructure behind the scenes to make everything work together!
NOT WEIRD!
I design trusses for BFS in Albuquerque. Sapphire Structure is awesome. I sell more jobs by showing my customer the design in 3d. For many it's the first time they have been able to visualize the structure since few home designers around here use 3d software.
Ya, let’s have computers do all the thinking for us so we can devolve into a stupid bliss blob

Informative video.. . I'm a truss designer it's a pleasure if I can help in any case of trusses designing
You guys produce a very professional video.
On trusses: Roof trusses are awesome and the automated factory made truss is the way to go.
Floor trusses are not so wonderful. They are more economical and have the advantage of space for utilities, but they are lethal to firemen. A 2 x 10 floor joist will withstand a considerable amount of fire before it fails, but the truss floor becomes extremely weak in just a few minutes of fire and a fireman walking onto a truss floor that has a fire below can easily fall through.
Just my opinion.
The reason that happens is because wood is a poor conductor of heat but metal is not. Thus the metal plates will expand much faster in heat than wood does causing them to fall off and making the tension points unstable.
@@milanroets9697 So making trusses using nails/screws would be way better than these plate-connected ones, right? Much slower, of course, but easier to DIY.
@@DanielZajic I was just stating that heat from a fire will theoretically cause the plates to come apart. Rafter framing is still way faster than putting them together yourself. Plus you still need engineered drawings with a stamp to pass inspection
I think the problem with floor joists failing has to do with heat affecting the glue in the truss and losing basically all strength.
This is a bad video. All one dude doing a low key sales pitch with almost no "how it's made" Bad move dude.
What's the downside? If I can design and have a custom home up to spec shipped in a watertight package that seems ideal.
Do you have the same availability of materials? Is there something this system can't do (yet)?
My adventure with the tree began with projects from Woodprix.
Those plates are complete garbage and are the largest factor in why the time to escape a house fire has fallen dramatically.
You need to edit the video as you have the compression and tension forces on the webbing the wrong way around!
"Subscribe if we've earned it" Best way to earn my subscription! Excellent video.
In Canada we see almost all trusses. The Sapphire viewer works great as you can search and see a certain truss.
I know you can find solutions to this problem in the Woodprix plans.
Commented to add that while informative, this is a slight over simplification of trusses. There are members in a truss that can be zero force members. For the curious, google zero force members.
Yeah, and I think most members deal with both tension and compression forces depending on the load condition.
I used to work for a truss manufacturing company years ago, it was the closest thing to sweatshop labor I’ve ever known
Any wood products place is like that. I works for LP and hated it. I wanted to get fired lol.
It’s like a prison lol
So you made a Truss fund, can you trust a truss! Is a truss distrustful? Can you truss anyone lol
This is so cool! I wish we had this available to us. I've never seen any setup like this before.
Ours is pretty close to this but not quite as professional looking.
I have done very similar with Woodglut designs.
They get to job site and they are to big or to small too tall or too low .never match.

Weak sauce compared to the EU shoot. Pretty much exemplifies how cheap we make everything in
the good ol USA.
There is NOTHING high quality about the way we build in the U.S. Not in a million years! It's just what you are used to, but it's not good. There is more money wasted in the long run in the extensive upkeep, maintenance, repair, and damage from natural causes that they don't even think about in other parts of the world. This is purely for profit making, builders make more profit from mesmerizing people with size, bells a whistles of new construction, and more profit made with all the extra repairs needed in the future. In America, we build garbage compare to the rest of the world... Really expensive garbage!
@@cwehbe I would add to that the "lack of longevity" of what we build here. Quite simply it's a waste
of trees. And I am no tree hugger. But it does start with mismanaged forests where out here in the west
the current forest management policy is to "Let it burn" Why allow logging when a fire can eliminate all
the work of cruising timber sales as we stop those evil loggers from making a profit in the name of
saving the forest for the future communist population I mean environmentalists? Logging is forest
management and fire control and it sets the lumber prices. You know where they are right now.
@Doug DeGrave Sure thing there, bud.
shalom1948hellyeah you need to get out more lol - you obviously have never seen true craftsmanship in the USA. I have seen it, Vietnamese, Mexicans, Guatemalans, Polish, Russians, Bulgarians are building amazing homes. the cookie cutter building industry demands low quality workers, supply and demand.
@@cwehbe I agree with you bluesky. When I first moved to US, especially with rentals, everyone was like - you need to account your operating costs! 50% of rent is for maintenance. And I'm like "WHAT?!?!" 50% howw? ... never in my life in Europe, maintenance has been 50% of rents. But I guess, when tenants can easily punch a hole on the wall then I guess there is a point there. Or having a water leak damage a lot of the structure. Heck, in Europe if you try to punch a wall, you will end up in the ER with broken knuckles ... as for water damage, we have had several leaks along the years and never damage. Floors and walls are concrete structures... then tile on bathroom and kitchen areas. Heck one time I had like 1 inch of water along my kitchen and all I did was just open the windows and waited for it to evaporate
I start in 7 hours at roof truss assembly manufacturer!
Can trusses be built on site by the builder and if not, why not? Didn't builders of another era use to do this from engineered tables and diagrams?
Trusses are an engineer product there is in house inspections third-party inspections and multiple code and criteria that must be followed everything has to be precise so for this to be built on-site would not be feasible or practical not to say that some short spans couldn't be built on site it's just that the plates and the pressing in the proper pressures and embedment of the plates would be almost impossible to ensure consistency
0:30 The bottom center web is so off-center that it's triggering my Obsessive Compulsive Disorder.
@Doug DeGrave You misunderstand. I think he means that the gangnail plate is not central to the king post (vertical strut) at the bottom or the fact the truss is truncated.
Truss plates do not have to be centered. The software can manipulate the location of the plate to reduce its overall size. Basically, each web and chord in a joint will often need a different number of teeth in each piece. When you center a plate you commonly over plate the webs and chords that have lower forces in them.
automated jig? lmao we are still setting up are table by hand
I lived in Europe, South Africa, Middle East, New Zealand and now in Canada. In all of them, I have had one or more houses built. The European build quality is most impressive above all of the other places.
In New Zealand they do a lot of wood building too. They have to consider the seismological impact an earthquake can have. Most of the wood framing (prenailing) is done off-site and trucked in. House walls and roof can be up in a few days. In Canada, with all its harsh climate pretty much all of the residential building is done with sticks.
Men and women go up against the bad weather putting a house together.
Why is this not done more off-site where the roof trusses are made. I can imagine you can bring back building time and weather impact of the building since it is not open for a long time.
PS
It is funny to see how thinly built North American residential houses are compared to European. Maybe North America should adopt more of the European building guidelines. It would make houses look better, last longer and be way more efficient.
No
I will try to do it with Woodglut plans.

I cannot finalize a plan until I get the truss information: bearing walls, point loads, uplift loads (choosing the proper connector), etc, so I can design the foundation appropriately.
Great vid! :)
I know people come here to see the latest high-end rez construction techniques and cool details. The truth is that workers who put all this wonderful stuff together, can only afford a used econo-box homes. It's OK that US housing stock is price-stratified, but how come blue collar affordability has to come on wheels from an Indiana Factory? And why do 7000SF house builders hate that?
I like the new guy.
I'm currently rebuilding all of the MiTek digital trusses on a job in Revit software so that proper coordination among all the service runs can occur during detailed design. The Truss Subcontractor couldn't even read the plans so I had to adjust their designs to make it work. When will Sapphire be able to output an ifc file format for proper coordination in a Federated model? Building Information Modelling is standard now days. The construction industry really does move at a snails pace.

This was very cool. I would like to have seen a closer look at the truss going down the line being put together. Are those plates very expensive? Would they be cost effective in building a shed?

Is it just me or is the workmanship rough. Tooth plates where theres no wood and not put on square
Don't assume that square is always the best orientation for a plate to join triangulated members. Many factories are equipped with lazers which project an outline of all of the members and plates onto the table for precise alignment.
How much more would it cost to use simple triangular roof framing, with a higher pitch if necessary, so the space would be unobstructed and possibly finished?
Not much. just a few more feet of wood really. But those are called bonus trusses. The truss company will tell you that they cost millions of dollars more to produce and no one really uses them anyway. Besides you would need a really big crane to set them because they weigh at least 50 pounds more. 50 pounds is a lot for an average crane. I am being facetious obviously. But I have actually been told this utter nonsense by the complete morons that work in my area. They charge whatever they feel like when you don't buy what they want to sell you. I hate trusses and truss companies and will avoid using them anytime I can. Trusses are nothing more than a way to build a roof as easily and cheaply as possible. They are not for building quality homes. One of my homes in Detroit was built in 1909 and has solid oak 2x4 rafters with 3 foot kneewalls in the attic. This gives me about 900 sq ft of space up there. Also I have replaced a few of the slate tiles on the roof but no more than 25 and the rest are original. You ever seen a 111 year old asphalt shingle that isn't a pile of grainy dust ? This is why we are seeing a push back to older technologies. They worked and worked well. Just because it is newer and cheaper does not mean it is better. But on the downside Trogdor hates slate roof cottages. He likes to burn down the peasants in their thatch roof cottages.
There is no cut and dry answer that will cover every situation so I have to give you one of those annoying "it depends" answers. On your typical 22' +/- wide garage going from a standard truss to a box attic one costs about $30-$40 per truss. Fink attics (webs look like a "W") with a 2x6 bottom chord are only about $10-20 per truss more than a standard truss. The cost increase comes from using larger lumber (eg bottom chord going from 2x4 to 2x12) increased lumber grades (eg 2x4 #2 might bump up to #1) larger truss plates, etc. Truss profiles like this are quite common (I see them on nearly every house I design trusses for) but they generally need to be specified on the plans or by the builder/customer.
What kind of cameras did you guys shoot on? Looks amazing!
On the job site, is drilling holes in the trusses frowned upon or forbidden? Holes for electrical, plumbing, AV, etc. Just wondering if nails, screws or holes compromise integrity of truss.
I've lived in Europe and North America. Here in NA we design a house to last 50 years. In Europe, at least when I lived there, the life cycle of a house was 300 years. Now I hear they to have dumbed down the product to 100+ years, which is still better than our life cycle of 50. As for trusses. I love them as a designer. They give me spans and options unavailable in the old span tables.
I want to build my own
If you ever played bridge builder, you'd know the web design is shite.
cool stuff!
How long can trusses be on the ground? So they were dropped off on the ground. How Much time do I have to install them?
I hate trusses!!
Even the freaking miter sawing and truss laying are becoming automated.
With truss companies expanding and making more money. Some are quite nice saws
2 years later... now art is being automated. No one is safe from technology lol
Thanks for showing the Mitek factory, awesome how the automation help produce a better product, use Mitek trusses all the time but never seen how they were made.
I'm a truss designer but I use Alpine software. Does anybody know both systems? What are key advantages and disadvantages?
So to hell with cut rafters huh, screw using skilled trades too? Oh wait mo money is the key!😉😖😔
