Common questions
How thick is 24 gauge steel?
- 24 gauge steel is 0.0239 inches thick, which is 0.61 mm. One square foot weighs 0.98 pounds. For reference that is thin enough to cut with heavy snips and bend by hand. Thicknesses are nominal and mill tolerance applies, so measure the sheet for anything structural.
What is 24 gauge steel in mm?
- 0.61 mm. The conversion is exact: 0.0239 inches times 25.4 gives 0.607 mm, rounded to 0.61.
Is 24 gauge stainless the same thickness as 24 gauge steel?
- No. 24 gauge galvanized is 0.0276 inches, stainless is 0.0250 inches, aluminium is 0.0201 inches, against 0.0239 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 24 gauge steel weigh?
- About 31 pounds. A 4 foot by 8 foot sheet is 32 square feet and 24 gauge weighs 0.98 pounds per square foot, so 32 times 0.98 is 31.2 pounds.
