Advantages of hot-dip galvanizing on the surface of Perforated Metal Sheet

Iron plate punching net products are easy to rust without surface treatment. Generally, surface treatment is required, and the most applied treatment method is hot-dip galvanizing. The principle of hot-dip galvanizing is to clean the outer surface of the punching net products. Clean, then solvent treatment, immersed in zinc solution after drying, iron and molten zinc to form an alloyed zinc layer, the process is: degreasing - washing - pickling - plating - drying - hot dip galvanizing - separate - cooling Passivation.

The thickness of the alloy layer of the product depends mainly on the chemical composition such as the silicon content of the sheet, the cross-sectional area of the sheet, the roughness of the surface of the sheet, the temperature of the zinc pot, the time of zinc dipping, the cooling speed, and the cold rolling deformation. The advantages of hot-dip galvanizing are: good reliability: the zinc layer and the punching net are metallurgical links and become part of the steel exterior, so the durability of the coating is relatively strong. Low processing costs: hot-dip galvanizing anti-rust costs are lower than other paint coatings, and the price is more advantageous.
Durable use: The standard hot-dip galvanizing rust-proof layer can last for 20 years without repairing, while the other treatment methods generally have a service life of less than 10 years. Save time and effort: The galvanizing process is more convenient than other coating methods and avoids the time required to apply on the job site after installation. Low initial cost: Under normal circumstances, the cost of hot dip zinc is lower than the application of other maintenance coatings, the reason is very simple.
Other maintenance coatings such as sanding paint are labor-intensive processes, whereas hot-dip galvanizing processes are highly mechanized and tightly controlled in-plant construction. The toughness of the coating: The galvanized layer forms an exceptional metallurgical structure that is mechanically damaged during shipping and use. Comprehensive maintenance: Every part of the punching net can be plated with zinc, which is fully protected even in recesses, sharp corners and hidden areas.
