We are working with 5" steel sips formerly from a refrigerated warehouse. I would be most appreciative if any of the experts could ID the brand from the photos below. There are 16 simulated "wood strips" to the surface (so about 2-5/8" each on a 42" panel). Both sides of the interlock are shown. I am also looking for engineering support (Philadelphia area) in order to reuse these panels for a residential roofing project. Our engineer has signed off on structure (24" o.c.) however we need direction for fastener pattern. We are thinking FMHLGM007 HeadLok screws with fender washers. Three per rafter? Four per rafter? Then attach roof sheathing with sheet metal screws or 8" spikes/screws right through to the rafters? Please help us put this fantastic material back into service and not in a landfill! Thanks, Ed/// It's my first post and can't seem to get the photos to load. So links shown. Thanks!

Looks close to Kingspan

It looks like their shadowline wall panel

Her is a picture I just took of KingSpan

Metecno Alumashield, an earlier brand bought out by Kingspan. The interlock is slightly different than the Kingspan interlock Chris posted.

Kingspan also bought out AlumaShield in Florida too. By the way my sample is 5" thick
