The production process of large rolls of galvanized wire is a level of drawing, through the mold into a slightly smaller diameter than the original. And so on down to the desired length. One pull is not desirable, must be numbered, from coarse to fine is dependent on metal ductility. If it changes too much it just breaks. After drawing to a certain diameter, galvanized, so that the finished product.

If the zinc coating is good, but when the light comes out in 3% nitric acid, there is a dark shadow on the coating, and the film is brown when passivation occurs, which may be caused by foreign metal impurities such as copper or lead in the galvanized liquid. When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.

Heavy duty hexagonal mesh made of steel wire by special machinery woven into a hexagonal mesh net. This kind of mesh can be cut and assembled into fence mesh, mountain hanging mesh, vegetation three-dimensional mesh, composite, etc. Aliases: Gabion mesh, heavy hexagonal mesh, ecological mesh, wire mesh, etc.

Materials of qualified quality should be kept marked for reference when used. In order to remove the surface film, surface inclusion and other defects on the surface of the large roll galvanized wire on the surface of the sedimentary layer to the local surface, it can be found and treated by conventional technology; Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless. The presence of small homogeneous particles of large denier in the tank can stabilize the foam layer, but the accumulation of too many solid particles can cause explosion.

1, must often clean and scrub the stainless steel pet cage, keep the surface of the stainless steel pet cage clean, dry, can ensure the stainless steel pet cage bright every day.

Now, hexagonal wire netting is widely used in Bridges, bridge piers and bridge bracket slope protection, cant bridge bracket, there are many people according to the gradient of slope to choose the right hexagonal wire netting, in gentle slope, people usually use bing slope protection system, and in the case of steep slopes, people will use the guest network gravity walls.

The common weight standard of galvanized barbed rope is 25kg per coil, and the length of each coil varies from 220-250 meters according to the specifications of the barbed rope. And of course we all know that the heavier the disc the longer it is. But there is one point that is worth our attention, that is, the hollow inside the general larger disk is relatively small, and the hollow inside the lighter galvanized thorn rope is relatively large. The purpose of this is to reduce the number of bending of the thorn rope and make it easier and more beautiful when installing, on the other hand, it looks larger in appearance.

This process has no mold, low processing cost, easy forming, can process a variety of shapes and other characteristics are widely used. But the products of the guardrail are powder impregnated plastic. According to whether it needs heating, it is divided into hot dipping and cold dipping. According to the raw materials of dipping, it can be divided into liquid dipping and powder dipping. Hot-dip galvanizing, as a metal anticorrosion method, is usually to put the steel structure to be derusted into the zinc liquid at about 500℃, so that the zinc layer is attached to the surface of the steel structure.
