Common questions
How thick is 13 gauge steel?
- 13 gauge steel is 0.0897 inches thick, which is 2.28 mm. One square foot weighs 3.66 pounds. For reference that is a little over three thirty-seconds of an inch. Thicknesses are nominal and mill tolerance applies, so measure the sheet for anything structural.
What is 13 gauge steel in mm?
- 2.28 mm. The conversion is exact: 0.0897 inches times 25.4 gives 2.278 mm, rounded to 2.28.
Is 13 gauge stainless the same thickness as 13 gauge steel?
- No. 13 gauge galvanized is 0.0934 inches, stainless is 0.0938 inches, aluminium is 0.0720 inches, against 0.0897 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 13 gauge steel weigh?
- About 117 pounds. A 4 foot by 8 foot sheet is 32 square feet and 13 gauge weighs 3.66 pounds per square foot, so 32 times 3.66 is 117.2 pounds.
