14 gauge steel thickness

14 gauge sheet steel is 0.0747 inches thick, or 1.90 mm. It weighs 3.05 lb per square foot, so a standard 4×8 sheet comes in around 98 lb.

What 14 gauge is used for

The workhorse gauge. Handrails, ornamental steel, light structural brackets, and heavy ductwork. Thick enough to weld without burn-through in most shop conditions.

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 3.12 lb/ft² for 14 gauge, based on a historical wrought-iron density — if a mill cert and your calculation disagree slightly, that is usually why.
