My foreman takes TERRIBLE photos ----- but this is the corrugated metal that is going on the walls in the "tool area" and along the back wall up to 10' height...
It's a very heavy gauge corrugated -- not the Home Depot variety that someone would buy for a shed roof.
It will give me good shop walls -- that won't be looking beat up 5 years down the road -- I can hang stuff right to it.... and or wash off something splashed without making a mess of a painted wall.
