The formula for calculating the weight of rectangular tube is 2× (side length 1+ side length 2- wall thickness )× wall thickness× length× density kg/m?
Square tube weight calculation company: 4× wall thickness× (side length-wall thickness )× 7.85 kg/m.
Extended information galvanized square pipes are divided into hot-dip galvanized square pipes and cold-dip galvanized square pipes according to the production process. It is precisely because of the different addition of these two kinds of galvanized square pipes that they have many different physical and chemical properties. There are many differences in strength, toughness and mechanical properties.
The production process of hot-dip galvanized square pipe is relatively simple, with high production efficiency and many varieties and specifications. This kind of square pipe needs less equipment and funds, and is suitable for small-scale galvanized square pipe manufacturers to produce. In terms of strength, the strength of this kind of steel pipe is far lower than that of seamless square pipe.
