0.8-1.3mm Prepainted Gi Steel Coil|Gi Cold Rolled Ring Coil

Galvanized coil hot dip galvanized advantage :

Continuous hot-dip galvanizing is widely used in the production of hot-dip galvanized steel coil. The process of continuous hot dip galvanizing method can be simply described as: original plate & GT; Pre-plating treatment (cleaning and annealing) & GT; Hot dip galvanizing & GT; Post-plating treatment (such as zinc flower treatment, alloy treatment and chemical treatment, etc.) & GT; The finished product.

1, low processing cost: the cost of hot dip galvanized rust is lower than the cost of other paint coating;

2, durable: in the suburban environment, the standard hot-dip galvanized rust prevention 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 installation in the site after the time required to brush;
