    sheet metal thickness

     



    Is 18 gauge a good thickness for replacing floor pans?

    14-16 is more typical for replacement pieces. 18 could work if you have frequent braces or could roll in some ribs or are spanning very short openings to very solid existing structure.

    It's much easier to promise someone a "free" ride on the wagon than to urge them to pull it.

    Luck occurs when preparation and opportunity converge.

    I agree 18 gage is only .048 thickness.Having worked with sheet metal the thinner the material the easier it is to form,but moves around when welding.IMO

    Anything thicker than 18 is a bear to work with IMO. As mentioned, rolled beads help stiffen it.

    I'm going to have to use some of this to make inner rockers and the floor braces weld to them. I think I'll take a little piece of the old rocker with me to see what's close.
