Thanks, JedClampett. I saw this company which is based in Canada. I tried calling them, but it did not go through. However, I believe this is a different company than the old Maryland based one that I need.
A thread similar to what I am looking for can be found here...
Hello,
Does anybody have an old load table for the Strescon Hollow Core Planks? I need to check the capacity of an existing roof structure that uses this type of roof deck. Thank you!
