Iron and steel in the condition of cooling on the surface galvanized, and hot dip galvanized steel pipe in the condition of hot dip on the surface, its adhesion is strong, not easy to fall off, hot dip galvanized pipe although also rust phenomenon, but in a long period can meet the technical and sanitary requirements.

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.

The production process of stainless steel blade and galvanized blade is basically similar. The blade size is usually determined according to the mold.

Now most people buy barbed rope choose blade barbed rope, why is this? The blade gill net is made of hot-dip galvanized steel plate or stainless steel sheet to punch out sharp knife sheets. The high tension galvanized steel wire or blade barbed wire is made of stainless steel wire as the core wire. Because the gill net shape is not easy to contact, so it can reach excellent protection barrier effect. The primary raw materials of the product are galvanized sheet and stainless steel plate.

The derusting steel parts are immersed in the melted zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to achieve the purpose of anti-corrosion. The surface of galvanized wire coating can see whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire.

There are many ways to choose the blade stabbing rope, and it is necessary to choose reasonably when choosing.

The hot plating wire is made of low carbon steel wire rod, which is processed by drawing forming, pickling and rust removal, high temperature annealing, hot dip galvanizing and cooling. Galvanized iron wire has resistance and elasticity, the amount of zinc can reach 300 g/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Widely used in construction, handicrafts, wire mesh, highway guardrail, commodity packaging and ordinary civilian and other fields.

Razor wire, also known as razor wire and razor net, is a new type of protective net. Blade barbed wire has beautiful, economic and practical, good anti-resistance effect, convenient construction and other excellent characteristics, at present, blade barbed wire has been widely used in many countries of industrial and mining enterprises, garden apartments, border posts, military fields, prisons, detention houses, government buildings and other countries of the security facilities.
