expanded metal standard

Hot dip galvanized coating is also relatively thick, but there is an uneven situation, for example, the thickness of the thin is only 45 microns, thick can reach 300 microns or even thicker, the color of this product is relatively dark. There is also a lot of zinc consumed in the production process. Zinc will form an infiltration layer with the metal. Its advantage is that it has good corrosion resistance. Electrogalvanizing, it is through the plating tank in the zinc one-way plating on the outside of the metal products, this way of making products is relatively slow, but its thickness is more uniform.

But there are some necessary precautions in the production of galvanized wire. Remove all tools and piles on the work site and equipment that hinder activities, and slowly put the wire into the cylinder during pickling to prevent acid splashing on the body. When adding acid, the acid must be slowly poured into the water. Do not pour water into the acid to prevent acid spillage and injury. Workers should wear protective glasses when working. Then in the handling of wire and other items, it is strictly prohibited to push hard.

Because of the pre-tension given to the packaging and binding of galvanized wire, it has the excellent characteristics of low relaxation value, small stress loss, good stability after loading, not easy to deformation, no fracture, strong elasticity, ordinary steel lines and rebar are difficult to compare. The use of advanced galvanized finishing process, therefore, the use of hot-dip galvanized steel wire construction, not only good corrosion resistance, but also beautiful and generous. The product has the characteristics of smooth surface, high dimensional accuracy, good uniformity of zinc layer and strong adhesion.

The quality of hot-dip galvanized barbed wire is only good in the surface of the wire attached to the galvanized layer, and with the chemical reaction, the surface of the zinc layer will gradually lose effect because of the oxidation reaction, this situation is more prominent in the humid area of the environment. And because after all, it is rusty iron wire, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.

Galvanized iron wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire) is made of low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. Galvanized iron wire has good toughness and elasticity, zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. The products are widely used in construction, handicrafts, wire mesh, galvanized hook mesh, spackle mesh, highway fence, product packaging and daily civilian and other fields.
