What is the nominal weight of 22-gauge stainless steel?

• A. 0.75 lb/ft2
• B. 1.31 lb/ft2
• C. 2.0 lb/ft2
• D. 3.0 lb/ft2

Answer: (B)

Nominal weight comes from how thick the sheet is and what material it’s made of. In stainless steel, 22 gauge corresponds to a thin sheet (about 0.033 inches thick). The weight per square foot is found by multiplying that thickness by the density of stainless steel (roughly 0.29 lb per cubic inch) and then converting to square feet (144 square inches per square foot). Doing that calculation gives about 1.3 pounds per square foot. Standard metal weight tables list 22‑gauge stainless at roughly 1.31 lb/ft², which is why this value is used as the nominal weight. Practical weight can vary slightly with alloy grade and temper, but 1.31 lb/ft² is the typical nominal figure.
