In the metal gauge system, smaller numbers indicate thicker material. Therefore, 11 gauge steel is thicker than 12 gauge. Specifically, 11 gauge is approximately 0.1196", while 12 gauge is 0.1046". This extra thickness provides significantly more structural rigidity.
The metric equivalent depends on the material. For Standard Carbon Steel, 11 gauge is 3.038 mm. For Stainless Steel, it is slightly thicker at 3.175 mm (exactly 1/8 inch). For Aluminum, 11 gauge measures 2.304 mm.
Standard 11 gauge carbon steel weighs 4.879 lbs per square foot (approx. 23.82 kg/m²). This makes it an ideal choice for heavy-duty applications where manual handling of parts is still a consideration during assembly.
Industrial tolerances for 11 gauge usually range within ±0.008" depending on the mill and the specific ASTM standard (like ASTM A1011). At SS Alloy Steel, we provide precision-leveled sheets to ensure maximum flatness for laser cutting.
