    I worked in a office where all the interior walls and workspace divisions were aluminum studs covered with this stuff. Held up well to people leaning against and using it as pin board for notes. Looked pretty cool too.

    Do you think that taking two squares and bonding them together with the corrugations at a right angle would work to make them stronger?

    Almost certainly. The difficulty is in successfully bonding polypropylene to itself. Polypropylene and Polyethylene are best bonded using heat and do not work really well with many adhesives. Even gorilla glue has warnings about its ineffectiveness with PP and PE.

    Scotch-Weld DP-8010 can do it, but application is not kitchen table friendly...

    3M also makes double-sided, and adhesive transfer, tapes with an acrylic adhesive (300LSE) that works well for bonding 'Low Surface Energy' materials like PP and PE plastics and powder-coat paint. Not sure you get the same coverage per cost as the epoxy and the bond is not as strong (cannot hang 240kg from it), but it often has a 2+ year shelf-life and is a bit easier and safer to use on multiple projects. 9274 appears to be among the best bonding with a ~115 Oz./In. peel adhesion at application and increasing a bit with time.
