Hot dipped Gi Square pipe is a name for square pipe, that is, steel pipes with equal side lengths. Hot dipped Gi steel pipe square tube is made of strip steel that has been processed and rolled. After unpacking, Flatten, crimp, and weld to form a round tube, which is then rolled into a square tube and cut to the required length. Generally, there are 50 square tubes per package. In terms of spot, the large size is mostly 10*10*0.8-1.5~~500*500*10-25. , Mechanical square tube, etc.
Calculation of theoretical weight per meter of galvanized square tube
4 * Thickness * (Side Length - Thickness) * 0.00785
Where the side length and wall thickness are in millimeters (mm), the value is directly substituted into the above formula and the result is the weight per meter of square tube in kilograms.
For example, for a 30 x 30 x 2.5 mm square tube, the weight per meter can be calculated according to the above formula: 4 x 2.5 x (30-2.5) x 7.85 = 275 x 7.85 = 2158.75 grams, i.e. about 2.16 kg.
When the wall thickness and side length are in millimeters, 4 x wall thickness x (side length - wall thickness) is calculated as the volume of each meter length of square tube, in cubic centimeters (cm3), multiplied by the specific gravity of iron 7.85 grams per cubic centimeter, resulting in the weight of each meter of square tube in kilograms
