Internal Garage Wall Ideas/Suggestions

my buddy got a deal on some sheet metal roofing (like you see on the roof of old barns and houses) and put it on his walls by far best garage wall you can have its safe for welding and such (fire hazard) and looks pretty good and big bonus is that he has a floor drain and when we paint a car we hose down the shop and absolutly no dust is left to fall down and fresh paint its totaly waterproof and also reflects light ... it might not be the cheapest but its good for a lifetime youll never have to redo it

this is defenatly what im gonna be doing to my garage over the next few years for shure.
oh and its extreamly easy to install there all 3 feet by 8 or 12 feet long and interlock one into the other....
