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 in cleaning after soldering the pipe, the method used to improve the activation of galvanized pipe surface quality. Production is now mainly dry method and redox square tube specifications, the characteristics are shown in 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 stainless steel pipe, but for single-sided coating, different coating thickness sided coating inner and outer surfaces, and thin-walled tube galvanized mused shall use this method.
