1, low processing cost: the cost of hot dip galvanized rust is lower than the cost of other paint coating;
2, durable: hot dip galvanized Angle steel surface gloss, uniform zinc layer, no leakage, no slip, strong adhesion, strong corrosion resistance, in the suburban environment, the standard hot dip galvanized rust thickness can be maintained for more than 50 years without repair; In urban and offshore areas, the standard hot-dip galvanized coating can be maintained for 20 years without repair.
3, good reliability: galvanized layer and steel is metallurgical combination, become a part of the steel surface, so the durability of the coating is more reliable;
4, the toughness of the coating is strong: galvanized layer forms a special metallurgical structure, this structure can withstand mechanical damage in transport and use;
5, comprehensive protection: each part of the plated parts can be plated with zinc, even in the depression, sharp corners and hidden places can be fully protected;
6, save time and effort: galvanizing process is faster than other coating construction method, and can avoid the time required to brush on the site after installation.
70x70x4 Hot dip Galvanized equal steel，Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle. It can be identified by the crystallization patterning on the surface (often called a "spangle").
The process flow of hot-dip galvanized angle steel: angle steel pickling → water washing → immersion in flux plating solvent → drying and preheating → rack plating → cooling → passivation → cleaning → grinding → hot-dip galvanizing completion. The thickness of the galvanized layer of the hot-dip galvanized angle steel is uniform, up to 30-50um. The galvanized layer and the steel are metallurgically bonded and become part of the steel surface, so the coating durability of the hot-dip galvanized angle steel is more reliable.
