(1) Since zinc has good ductility, its alloy layer is firmly attached to the steel base, so the galvanized square tube can be formed by cold punching, rolling, wire drawing, bending, etc. without damaging the coating;
(2) After hot-dip galvanizing of steel structural parts, it is equivalent to one-time annealing treatment, which can effectively improve the mechanical properties of the steel matrix, eliminate the stress during forming and welding of the steel parts, and is conducive to the turning of the steel structural parts.
(3) The surface of the hot-dip galvanized square tube is bright and beautiful.
(4) The pure zinc layer is the most plastic galvanized layer in hot-dip galvanizing. Its properties are basically close to that of pure zinc, and it is ductile, so it is full of flexibility.
