Hey guys i got to thinking which sometimes isn't a good thing for me.But anyway i need a bigger shop.Got to wondering why not build the frame out of metal.Like 2inch angle iron.Im thinking it would be cheaper than wood and just as simple if not easier considering im a welder(or used to be).Could even set studs farther apart like 4ft centers.Then just cover with tin,like they use for roofing and carports.Attached with self tapping screws,or pre drilled holes pending cost of s/t screws.Metal framed doors could be welded in. It would also make grounding stuff for welding much simpler. Hopefully ill have the money to also pore a concrete floor complete with I-beam set in it to also use for grounding (tacking and bending) and to hold up over head rolling chain host on I-beam. Any thoughts about this? Other things to consider adding in?
