HySpan and HyBeam structural members
Our designer has spec'd HySpan and HyBeam members for our floor. I haven't had any experience with these and just wanted to know what people think. I know they are a laminated product and so they should be pretty strong. Some of the sizes look a bit small to me though: eg. bearers are 140mm by 65mm, joists 100m x 45mm. In hardwood, that would be like a trampoline.
The sizes are punched out by their design software so I guess they are right. I don't want a bouncy floor, so what do you reckon?
