What Is Galvanized Angle Steel?
Galvanized Angle Steel is divided into hot-dip galvanized angle steel and cold-galvanized angle steel. Hot-dip galvanized angle steel is also called hot-dip galvanized angle steel or hot-dip galvanized angle steel. The cold galvanized coating mainly ensures the full contact between the zinc powder and the steel through the electrochemical principle, and generates the electrode potential difference for anti-corrosion.
Hot-dip galvanized angle steel is also called hot-dip galvanized angle steel or hot-dip galvanized angle steel. The rust-removed angle steel is immersed in a molten zinc solution at about 500 ° C, so that the surface of the angle steel adheres to the zinc layer, so as to achieve the purpose of anti-corrosion, and is suitable for various strong acid, alkali mist and other strong corrosive environments.
Process: hot-dip galvanized angle steel process: angle steel pickling → water washing → dipping in solvent → drying and preheating → rack plating → cooling → passivation → cleaning → grinding → hot-dip galvanizing completed.
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 raw material of hot-dip galvanized angle steel is angle steel, so it is classified the same as angle steel.
Advantages Of Galvanized Steel Angle:
1. Low processing cost: the cost of hot-dip galvanizing anti-rust is lower than that of other paint coatings;
2. Durable and durable: hot-dip galvanized angle steel has the characteristics of surface gloss, uniform zinc layer, no leakage plating, no dripping, strong adhesion and strong corrosion resistance. In the suburban environment, the standard hot-dip galvanized anti-rust thickness can be maintained. More than 50 years without repair; in urban or offshore areas, the standard hot-dip galvanized anti-rust layer can be maintained for 20 years without repair;
3. Good reliability: The galvanized layer and the steel are metallurgically bonded and become part of the steel surface, so the durability of the coating is more reliable;
4. The toughness of the coating is strong: the galvanized layer forms a special metallurgical structure, which can withstand mechanical damage during transportation and use;
5. Comprehensive protection: every part of the plated parts can be galvanized, and can be fully protected even in depressions, sharp corners and hidden places;
6. Time-saving and labor-saving: The galvanizing process is faster than other coating construction methods, and it can avoid the time required for painting on the construction site after installation.
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 auxiliary facilities, light industry, etc.
