Weight calculation formula of galvanized rectangular steel pipe

The formula for calculating the weight of the national standard galvanized rectangular steel pipe. According to the formula, the amount can be calculated. Let's take a look:

4 x wall thickness x (side length-wall thickness) x 7.85

The numerical value, side length and wall thickness are all in mm, and the numerical value can be substituted into the formula. The result is the weight per meter of the national standard galvanized rectangular steel pipe in grams. 

E.g:According to the above formula, the weight per meter of 30mm x 30mm x 2.5mm galvanized rectangular steel pipe can be calculated as: 4 x 2.5 x (30-2.5) x 7.85 = 275 x 7.85 = 2158.75 grams, which is 2.16 kg

When the wall thickness and side length are in mm as the unit, 4 x wall thickness x (side length-wall thickness) is calculated as the volume of the rectangular steel pipe per meter length, in cubic centimeters, multiplied by the specific gravity of iron per meter The cubic centimeter is 7.85 grams, which is the weight of the square steel pipe per meter in grams. (Length + width)×2×0.00785×thickness×1.06=kg/m, where 1.06 is the galvanized layer coefficient.
