Roofing panels, flashing, trim, and light covers. Typically formed and fastened, not structurally welded.

Galvanized and stainless use their own gauge series — the same gauge number is a different thickness in each. Reading a galvanized order off a plain steel chart is one of the most common ordering mistakes in the shop.

Weight is calculated at 40.84 lb/ft² per inch of thickness. The Manufacturers' Standard Gauge quotes a nominal 1.00 lb/ft² for 24 gauge, based on a historical wrought-iron density — if a mill cert and your calculation disagree slightly, that is usually why.
