Galvanizing Method Of Galvanized Square Tube

- Jun 30, 2017 -

Galvanized Square tube has hot-dip galvanized and galvanized two broad categories. Hot Dip galvanizing has wet method, dry method, lead and zinc method, oxidation reduction method and so on. The main difference between different hot dip galvanizing methods is how to activate the surface of the tube to improve the quality of galvanized steel after pickling. Dry method and redox method are mainly used in production. Galvanized Zinc coating surface is very smooth, dense, uniform, good mechanical properties and corrosion resistance, zinc consumption of galvanized low $number. Electroplating Zinc has a certain degree of complexity in technology, but it is necessary to apply this method to one-sided coating, double-sided coating with different coating thickness, and thin-walled tube galvanized.
