The galvanized square tubing is a hollow square section steel tube with a square cross-sectional shape and a shape obtained by hot-rolling or cold-rolling galvanized steel strip/coil as a blank after cold bending forming and then high-frequency welding. Or a galvanized square pipe made of cold-formed hollow steel pipe which has been prepared in advance and then hot-dip galvanized. It is precisely because of the different processing of these two galvanized square tubes that they have many different physical and chemical properties. In general they have many differences in strength, toughness and mechanical properties.
