Hot dip galvanized Angle steel
Hot dip galvanized Angle steel is also called hot dip galvanized Angle or hot dip zinc Angle steel. It immerses the Angle steel after derusting into the molten zinc about 500℃, so that the surface of the Angle steel is attached with zinc layer, so as to play the purpose of anticorrosion, suitable for all kinds of strong acid, alkali fog and other strong corrosive environment.
Process: hot dip galvanized Angle steel process: Angle steel pickling → water washing → dip assisted plating solvent → drying preheating → hanging plating → cooling → passivation → cleaning → grinding → hot dip galvanized completion.
Hot dip galvanized Angle steel galvanized layer thickness uniform, up to 30-50um, good reliability, galvanized layer and steel is metallurgical combination, become a part of the steel surface, so hot dip galvanized Angle steel coating durability is more reliable. The raw material of hot dip galvanized Angle steel is Angle steel, so the classification is the same in Angle steel.
