I'm evaluating an old warehouse building that has 2' wide, wood cement fiber planks that span about 7' between steel support beams. The planks are about 3-1/4" thick and appear to have #5 embedded reinforcement along each edge. I'm wondering if anyone knows what this system is and if so, do they have any documentation and/or load tables. Although it's similar to tectum or petrical, I'm not aware of either system having internal reinforcement. I also don't think it's porex or insulrock. I've attached a photo of the system. The building is located in NJ and my best guess is it's from the 60's/70's era. Any help would be appreciated.
At the same facility, there is also a roof section that has 2" tectum/petrical supported from below by cold formed box purlins with a continuous slot at the top. If anyone has information on the box purlin system or the fasteners, it would be appreciated. I've attached a photo of this also. There was a 2009 post of a building in Buffalo that had the same system. You can see the box purlin profile in the photo where they infilled an old opening with metal deck - they obviously didn't reinforce the support around the opening. The box shape is 2-3/8" in height by 1-7/8" in width and is only about 16 gauge. 7' spans with 2'-8" spacing.
