Galvanized square tube
Galvanized square tube Characteristic
Galvanizing has stronger protective effect and strong corrosion resistance. The entire structure is made of zinc, forming a dense quaternary crystal. This crystal forms a barrier on the steel plate, thus effectively preventing corrosion factors from penetrating. Corrosion resistance comes from the strong protective barrier layer of zinc. When zinc provides sacrificial protection on trimmed edges, scratches, and abraded parts of the coating, the zinc forms an insoluble oxide layer and exerts a barrier protection function.

Among them, the side length and wall thickness are both in millimeters (mm). Substituting the values directly into the above formula, the result is the weight of the square tube per meter, 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, which is about 2.16 kilograms.
When the wall thickness and side length are both in millimeters, 4x wall thickness x (side length - wall thickness) calculates the volume of the square tube per meter of length, in cubic centimeters (cm3), multiplied by the specific gravity of iron 7.85 grams per cubic centimeter, which is the weight in kilograms per meter of square tube.
