I've been putting 4x8 sheets around my space as wainscot, or whatever. Getting it a metal supply yard that gets it as seconds, thin gauge diamond bright. Coca Cola red walls from there up. Been paying $97 to $100 a sheet so far and polishing out a few dull spots that qualify it as "seconds".
I chose this over the corrugated tin material with the lines running vertical, again as wainscot. It is in several bars and restaurants in the area and I still like it.
I belong to a private club that got some shiny finish thin panels that look like antique ceiling tiles. Used them to wrap the bar area and it is holding up pretty good so far.
