The advantages of hot-dip galvanizing
1, the processing cost is low: the cost of hot-dip galvanized anti-rust coating than other low cost of paint;
2, durable: in the suburban environment, the standard hot-dip galvanized anti-rust thickness can be maintained for more than 50 years without having to repair; in urban or coastal areas, the standard hot dip galvanized layer can be maintained for 20 years without repair ;
3, the reliability is good: galvanized steel pipe and steel is metallurgical combination, as part of the steel surface, so the durability of the coating is more reliable;
4, the coating toughness: galvanized layer to form a special metallurgical structure, this structure can withstand the mechanical damage during transport and use;
5, a comprehensive protection: plating of each part can be plated with zinc, even in the depression, sharp corners and hidden place can be fully protected;
6, save time and effort: galvanizing process than other coating construction method is more efficient, and can avoid the installation site after brushing the time required.
7, the initial low cost: Under normal circumstances, the cost of hot-dip zinc coating than other protective agents is lower, the reason is very simple, other protective coatings such as sand paint is a labor-intensive processes, on the contrary hot zinc process is high Mechanization, close control of the plant construction.
8, the test is simple and convenient: hot dip zinc layer can be visual and simple non-destructive coating thickness table for testing
9, reliability: hot dip zinc specifications are generally in accordance with the BS EN ISO 1461 implementation, limits its minimum zinc layer thickness, so the rust-proof period and performance is reliable and predictable.
