Q: I’m currently cruising the internet looking for the best way to support a ceiling via suspension from structural steel. We’re building a freezer, and I don’t want thermal bridging from the inside of the freezer up to the structural steel, so a metal rod is pretty much out of the running. Any suggestions?

A: For this application I would recommend looking at a PEEK screw. PEEK is one of the strongest polymer fasteners, especially when reinforced with glass fibers,  and like most polymers offers low thermal conductivity which would be ideal for your freezer application.
