Galvanized angle steel is divided into hot-dip galvanized angle steel and cold-dip galvanized angle steel. Hot-dip galvanized angle steel is also called hot-dip galvanized angle steel or hot-dip galvanized angle steel. The cold-dip galvanized coating mainly ensures full contact between the zinc powder and the steel through the electrochemical principle and generates an electrode potential difference for anti-corrosion.

We all know that galvanized angle steel is divided into hot-dip galvanized angle steel and cold-dip galvanized angle steel. Uses of galvanized angle steel: Widely used in power towers, communication towers, curtain wall materials, shelf construction, railways, road protection, street light poles, marine components, building steel structure components, substation ancillary facilities, light industry, etc.

Hot-dip galvanized angle steel is also called hot-dip galvanized angle steel or hot-dip galvanized angle steel. The cold-dip galvanized coating mainly ensures full contact between the zinc powder and the steel through the electrochemical principle and generates an electrode potential difference for anti-corrosion. It is to immerse the angle steel after derusting in the molten zinc at about 500 ℃ so that the surface of the angle steel is attached with a zinc layer, so as to achieve the purpose of anti-corrosion, and it is suitable for various strong corrosive environments such as strong acid and alkali mist.

After understanding the use of galvanized angle steel, let's take a look at the process of galvanized angle steel: pickling of angle steel → water washing → immersion in plating solvent → drying and preheating → rack plating → cooling → passivation → cleaning → grinding → hot dipping Zinc finish. The thickness of the galvanized layer of the 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, so the coating durability of the hot-dip galvanized angle steel is more reliable.
