Common questions
How thick is 11 gauge steel?
- 11 gauge steel is 0.1196 inches thick, which is 3.04 mm. One square foot weighs 4.88 pounds. For reference that is a hair under an eighth of an inch. Thicknesses are nominal and mill tolerance applies, so measure the sheet for anything structural.
What is 11 gauge steel in mm?
- 3.04 mm. The conversion is exact: 0.1196 inches times 25.4 gives 3.038 mm, rounded to 3.04.
Is 11 gauge stainless the same thickness as 11 gauge steel?
- No. 11 gauge galvanized is 0.1233 inches, stainless is 0.1250 inches, aluminium is 0.0907 inches, against 0.1196 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 11 gauge steel weigh?
- About 156 pounds. A 4 foot by 8 foot sheet is 32 square feet and 11 gauge weighs 4.88 pounds per square foot, so 32 times 4.88 is 156.3 pounds.
