duct sheet gauge is not fixed for any size, it depends on ESP of the fan and project specifications. I tried to use maximum thickness, for your calculation you can use, same gauge as you are using. normally we follow three pressure classes. 1- low 2-medium 3-high.

Can you correct me if I'm not wrong for 1500x800 duct size is 20 gauge or 16 gauge bas i know 1500-2200mm 20g near about 1mm is enough
