24' Truss design for 4' OC

[Hay Dude]

I’d probably ask a local truss salesman/fabricator. Go with 3/4” sheathing over your trusses to beef them up? Then do purlins.

With the price of lumber i went with CFS to fabricate trusses in-situ in our tractor shed. IIRC each truss was $200 in material. Installed on. 12' centers. Original construction was a simple king truss holding up a ridge board. Trusses were sagging at the center 3' nailed overlap. Carpenter bees don't mess with the galvanized steel.
