Different from double strands of barbed wire to install directly on the ground, the blade thorn rope is fixed on some affiliate products just again, as was the case according to the common on the wall, often wall width is far lower than the diameter of the blade thorn rope under the premise of no such device is fixed in place, use special stents to prevent blade thorn rope can better protect us.

1. Adjust electroplating process parameters

There are two varieties of steel grid plate is pressure welded steel grid plate and pressure lock steel grid plate, in many people’s eyes, these two products belong to the same variety, in fact, there are still great differences between them in many places.

As we all know, the mechanism of resistance to atmospheric corrosion of zinc includes mechanical protection and electrochemical protection. Under the condition of atmospheric corrosion, there are ZnO, Zn(OH)2 and basic zinc carbonate protective film on the surface of zinc layer, which to a certain extent slows the corrosion of zinc. When this protective film (also known as white rust) is damaged, a new film will be formed.

Now most people buy barbed rope choose blade barbed rope, why is this? From the material blade barbed wire technology blade gill net is made of hot-dip galvanized steel plate or stainless steel sheet stamped out sharp knife sheet, high tension galvanized steel wire or blade barbed wire stainless steel wire as core wire combination of the resistance device. Because the gill net shape is not easy to contact, so it can achieve excellent protective barrier effect. The primary raw materials of products are galvanized sheet and stainless steel plate.

(1) The application method of packaging and binding galvanized shaft wire ordering: ① the pulling position on the goods should be reasonably selected. When used to avoid horizontal movement of goods, the pulling position should be as low as possible; When used to avoid overturning the goods, the pulling position can be appropriately high. ② The use of galvanized iron wire [1] pull reinforcement methods mainly include: figure eight, inverted figure eight, cross, zigzag or reverse zigzag and so on. Various pull methods can be used alone, but also two or more than two kinds of use. The pull should be as symmetrical as possible. (3) When pulling reinforcement, the single or double strands of galvanized iron wire will reciprocate around the goods and vehicles between the two tying nodes, and should be pulled tight galvanized iron wire so that the tightness of each strand is as common as possible, and some of the remaining cross around its own rope rod, and the rest of the tail toward the car.

Decorative hook mesh selection of stainless steel, aluminum alloy, brass, copper and other alloy materials, through the special process of preparation of hook mesh. It is a silk screen made of decoration. Today we introduce the aperture and wire diameter of the decorative hook mesh.

Low and medium carbon steel wire is used as raw material, with good surface gloss, uniform zinc layer, strong adhesion, corrosion resistance and so on. Available: diameter 1.60mm-4mm (16#-33#) cold plating wire; Diameter 6.40mm-0.81mm(8#-21#) black iron wire, changed wire. It is mainly used in communication equipment, medical equipment, weaving net, brush, steel cable, filter, high-pressure pipe, construction, crafts and other industries.

Compared with the traditional braided and twisted barbed rope, the price of raw materials is relatively high because of the relatively complex technology.

Hexagonal guardrail net custom corrosion lost the original characteristics, in the shape, color and mechanical properties will change, resulting in equipment damage, pipeline leakage, etc., specifically, is prone to fracture, lose the original protection function. Usually there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the customized corrosion of hexagonal guardrail net and extend the service life of the product.

Steel wire and iron wire have many similarities, but carefully distinguish, will find that they are not only different in the material, but also in the product characteristics of the great difference. So when choosing, be sure to make a clear distinction between the two. Steel wire factory introduces steel wire carbon structural steel made above, generally not galvanized, used for machinery, spring. Black, very hard; Wire: made of mild steel (mild steel), galvanized, used for joining and binding. White and soft.
