Your building will be designed with U.S. steel (if delivered in the US) and by some of the most rigid standards in the world. The steel will all be 55,000 psi tensile strength, this is for all primary and secondary steel. All structural steel will be primer coated for rust protection.
Sheeting is standard 26 or 24 gauge, (industry standard) and 80,000 psi tensile strength. This material is galvalume to resist rust, then silicone-polyester painted (if standard paint (SP).
