The minimum recommended slope for any Delta Rib roofing panel is 3:12. Metal Sales recommends that in all
roof applications sealant be used on sidelaps.
Delta Rib is designed to be utilized over open structural framing, but can easily be used with a solid substrate.
The recommended substrate is 5 /
8
" plywood with a 30 pound felt moisture barrier. To avoid panel distortion, use
a properly aligned and uniform substructure.
Each panel has a coverage of 24".
Lengths under 5'-0" are available with some cutting restrictions. Maximum recommended panel length is 45'-0".
Longer panels require additional consideration in packaging, shipping, and erection. Please consult your Metal
Sales branch for recommendations (see PGI-2 and PGI-3 for locations).
Panels are available in 30, 29, and 26 gauge. Minimum quantity may apply.
Commercial, Industrial, and Architectural panels.

The fastener selection guide should be consulted for choosing proper fasteners for specific applications.
