Common questions
How thick is 22 gauge steel?
- 22 gauge steel is 0.0299 inches thick, which is 0.76 mm. One square foot weighs 1.22 pounds. For reference that is about a thirty-second of an inch, noticeably floppy in a large panel. Thicknesses are nominal and mill tolerance applies, so measure the sheet for anything structural.
What is 22 gauge steel in mm?
- 0.76 mm. The conversion is exact: 0.0299 inches times 25.4 gives 0.759 mm, rounded to 0.76.
Is 22 gauge stainless the same thickness as 22 gauge steel?
- No. 22 gauge galvanized is 0.0336 inches, stainless is 0.0312 inches, aluminium is 0.0253 inches, against 0.0299 inches for uncoated steel. Each material is tabulated under a different standard, so the gauge number alone does not give a thickness.
What does a 4x8 sheet of 22 gauge steel weigh?
- About 39 pounds. A 4 foot by 8 foot sheet is 32 square feet and 22 gauge weighs 1.22 pounds per square foot, so 32 times 1.22 is 39.1 pounds.
