For example, G90 means the zinc coating of one square foot of sheet weighs 0.90 ounces.īelow is a table showing the commonly used codes for your reference. These numbers refer to the weight of zinc in Inch-Pound units of measurement. G90 indicates the zinc coating thickness of galvanized steel according to ASTM standards, such as G60, G140, etc. Which Is Thicker, 20 Gauge or 22 Gauge Steel?įor the same material, 20 gauge is thicker than 22 gauge. GAUGE TO THICKNESS CHART TABLA DE EQUIVALENCIA DE CALIBRE Y ESPESOR Stainless Galvanized Sheet Steel Aluminium Acero Inoxidable Galvanizado Lámina de Acero Aluminio Gauge Fraction in (mm) in (mm) in (mm) in (mm) Calibre Espesor / Thickness Fracción 30 0.0125 (0.33) 0.0157 (0.40) 0.0120 (0.30) 0.0100 (0. It’s less likely to dent or deform if struck with a falling object. W= Thickness (mm) * Width (m) * Length (m) * 7.85 (Density of steel = 7.85 kg/m 3) + zinc layer weightĢ8 gauge is 0.475 mm, and the width and length are about 1.219 m and 2.438 m. Thicker is better when it comes to steel gauge: A 16 gauge stainless steel sink is more durable than a 20 gauge one. The weight of galvanized sheet is calculated by the formula: Let’s take 28 gauge galvanized sheet metal 4×8 for example.

How to Calculate the Weight of Galvanized Sheet?
The chart below shows the equivalent sheet gauge thickness in inches or millimeters. For example, 16 gauge galvanized steel sheet thickness is 1.6129 mm (0.0635 inches) while 18 gauge galvanized steel sheet thickness is 1.3106 mm (0.0516 inches). The gauge thickness is a measure of the thickness of the metal, with a higher gauge number indicating a thinner material. Generally, for the same material, the higher the number, the thinner the metal sheet. A steel gauge conversion chart is a table that shows the various gauge thicknesses of different types of metal, including steel. The M stands for magnetic material the number is representative of the core loss of that grade. Besides, steel sheets and pipes of the same Ga. The American Iron and Steel Institute type numbers and AK Steel designations for electrical steel grades con-sist of the letter M followed by a number. But the non-ferrous metal and mild steel of the same Ga., their thicknesses are different. It is essential to keep a copy of the gauge Chart handy when you design any part. For example, the 16 gauge stainless steel thickness is 1.60 mm, whereas the 16 gauge aluminum thickness is 1.29 mm. We often use gauges with numbers to show the thickness or diameter of materials. One point must be noted that the thickness will be different for different materials for the same gauge. Gauge (Ga.) is a measurement unit of the thickness of a thin material (such as sheet metal or plastic film).
