Difference between hot galvanizing and cold galvanizing of welding mesh

According to the galvanized surface treatment method, the welding mesh is divided into hot-dip galvanized welding mesh and galvanized electric welding mesh (cold galvanized welding mesh).

Process flow of galvanized electric welding mesh: it is made of high-quality black wire or galvanized wire through fully automatic welding mesh machine controlled by computer, and then galvanized, with uniform mesh, firm welding, smooth mesh surface, stronger corrosion resistance and strong protection ability. Due to its strong corrosion resistance, the galvanized wire mesh produced by Wanzhi is widely used in Shaanxi, Ningxia, Hunan and Hubei, and is deeply favored by the aquaculture industry.

Performance characteristics of hot-dip galvanized welding wire mesh:

1. It can avoid the contact between steel matrix and any corrosion solution and protect steel matrix from corrosion. 2. It has Fe Zn alloy layer with dense bonding, which shows unique corrosion resistance in marine salt fog atmosphere and industrial atmosphere; 3. Strong wear resistance due to strong bonding; 4. Due to good ductility of zinc, its alloy layer is firmly attached to steel base, so hot-dip galvanized parts can be formed by cold stamping, rolling, drawing and bending without damaging the coating; 5 After hot-dip galvanizing, it is equivalent to one annealing treatment, which can effectively improve the mechanical properties of steel matrix, eliminate the stress during forming and welding of steel parts, which is conducive to turning steel structural parts. 6. After hot galvanizing, the surface is bright and beautiful. 7. Pure zinc coating is the most plastic zinc coating in hot-dip galvanizing. Its properties are similar to that of pure zinc. It has ductility, so it is flexible.

Performance characteristics of galvanized and welded wire mesh:

1. Zinc coating is thick, fine crystal, uniform and no pores, good corrosion resistance; 2. The zinc coating obtained by electroplating is relatively pure, and corrosion in acid, alkali and other fog is slow, which can effectively protect the steel substrate; 3. The zinc coating after chromate passivation forms white, color, military green, etc., which is beautiful and elegant, and has certain decoration; 4. Due to the good ductility of zinc coating, it can be carried out Cold stamping, rolling, bending and other forming without damaging the coating.

The galvanized electric welding mesh can be used as the bottom net and fence for raising chickens, ducks, geese and rabbits, sheep, bamboo rats and so on.
