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.
Galvanized Angle steel is widely used in power tower, communication tower, curtain wall material, shelf building, railway, highway protection, lamppost, Marine components, building steel structure components, substation auxiliary facilities, light industry, etc.

Galvanized channel steel is an effective metal anticorrosion method, mainly used in various industries of metal structure facilities.
Hot dip zinc is one of the best coating methods to protect steel substrate. It is in the liquid state of zinc, after a rather complex physical and chemical action, on the iron and steel not only coated with a thick layer of pure zinc, but also generate a zinc-iron alloy layer. This plating method not only has the corrosion resistance of electrogalvanizing, but also has a zinc-iron alloy layer. It also has strong corrosion resistance that can not be compared with electric galvanizing. Therefore, this plating method is especially suitable for all kinds of strong acid, alkali fog and other strong corrosive environment.
Folding edit this section principle
Hot dip galvanizing layer is formed by zinc in a high temperature liquid in three steps:
1. The surface of iron base is dissolved by zinc liquid to form zinc-ferroalloy phase layer;
2. Zinc ions in the alloy layer further diffuse to the matrix to form a zinc-iron intersoluble layer;
3. The surface of the alloy layer is surrounded by a zinc layer.
