Process flow and use of hot-dip galvanized steel angle bar

Hot-dip galvanized steel angle bar is to immerse the derusted angle steel in a molten zinc solution at about 500°C to attach a zinc layer to the surface of the angle steel to achieve the purpose of anti-corrosion. It is suitable for various strong acids, alkali mists and other strong corrosive environments.

Process: hot-dip galvanized angle steel process: angle steel pickling → water washing → immersion assist plating solvent → drying and preheating → rack plating → cooling → passivation → cleaning → polishing → hot-dip galvanizing completion.

The thickness of the galvanized layer of hot-dip galvanized angle steel is uniform, up to 30-50um, and the reliability is good. The galvanized layer and the steel are metallurgically bonded and become a part of the steel surface. Therefore, the durability of the coating of the hot-dip galvanized angle steel is more reliable. . The raw material of hot-dip galvanized angle steel is angle steel, so the classification is the same as angle steel.

Galvanized angle steel is widely used in power towers, communication towers, curtain wall materials, shelf construction, railways, highway protection, street light poles, marine components, building steel structural components, substation ancillary facilities, light industry, etc.
