What is the hot-dip galvanized angle process?
Hot dip galvanized angle steel is also called hot dip galvanized angle steel or hot dip zinc angle steel. It is to remove rust after the angle steel immersed in about 500 ℃ melting zinc liquid, so that the angle steel surface attached to the zinc layer, so as to play the purpose of anti-corrosion, suitable for a variety of strong acid, alkali fog and other strong corrosive environment.
Process
Angle pickling - washing - dip the solvent to help plating - drying preheating - hanging plating - cooling - passivation - cleaning - grinding - hot dip galvanized completed. Hot-dip galvanized steel angle of the galvanized layer thickness is uniform, up to 30-50um, good reliability, galvanized layer and steel is metallurgical bonding, become part of the steel surface, so hot-dip galvanized steel angle of the coating durability is more reliable.
Main classification
The raw material of hot-dip galvanized steel angle is steel angle, so it is classified in the same way as steel angle. According to the process classification can be divided into hot-dip galvanized hot-rolled angle and hot-dip galvanized cold-rolled angle. The market is commonly hot rolled hot dip galvanized steel angle. Hot-dip galvanized cold-rolled angle, generally need to be customized according to user needs with cold-rolled sheet. According to the side length can be divided into hot-dip galvanized equilateral angle steel and hot-dip galvanized unequal angle steel.
