Galvanized square tubes from the production process is divided into hot galvanized square tube and cold galvanized square tubes. It is because of these two galvanized square tube plus they are not the same as it created a lot of different physical and chemical properties. In general they have a lot of difference between strength, toughness and mechanical properties in. Galvanized square tube is a tool in hot or cold galvanized steel or galvanized coil to the blank square cross-section shape and size of the cold bending molding and then made by high-frequency welding hollow square-section steel pipe ; or well in advance of the cold-formed hollow type and then by the hot-dip galvanized steel processing galvanized Rectangular Pipe.

Galvanized square pipe hot galvanized square pipe and galvanized square tube into two categories. Galvanized square tubes have wet, dry, lead and zinc method, redox method. The main difference between the different methods of hot-dip galvanized steel pickling after cleaning, the method used to improve the activation of galvanized pipe surface quality. Production is now mainly dry method and redox method, which features table. Galvanized zinc coating surface is very smooth and dense, uniform organization; has good mechanical properties and corrosion resistance; zinc consumption 60% to 75% lower than the hot-dip galvanizing. Galvanized technically certain complexity Zhaodong cable bridge how, but for single-sided coating, different coating thickness sided coating inner and outer surfaces, and thin-walled tube galvanized mused shall use this method.
