5 V crimp roof

struct_eeyore · Feb 9, 2018

Hi all,

Is anyone familiar with using 5V crimp as a roofing material? One client has a structure with a 5Vcrimp bearing at 24" o.c. with no plywood under - I found a load table online that claims 24 psf for 1-span condition with supports at 24" o.c (29 gauge sheets). To me this just seems a bit over the top... any thoughts? Thanks!

5V crimped galvanized steel has been used for a roofing material for many years. It has a long record of service. That is the "tin roof" you have seen on many old barns and sheds. Usually has no decking under it. It is fairly hefty as a structural section so your values don't surprise me.

I m not surprised either. Walking on top of it would be sketchy unless you stayed on the purlins. I usually spec the purlins 16" O.C. for that reason.
