I bought boards, timber. The quality of lumber is my opinion, reflection. I went to the huge construction market for lumber, boards and timber. I probably chose the best of the worst. The boards do not correspond to the dimensions, the boards are not even. And so it is everywhere for everyone. If you don't keep track of what is being loaded to you, then they will load everything in a row - both crooked and oblique. You need to choose each board yourself. There is a lot of obzol on the boards. Be sure to take a tape measure with you and measure everything.
