From the point of view of spray, spray blade gill net (PVC blade gill net, coated blade gill net) is also called spray blade barbed wire, spray blade barbed wire is the blade barbed wire produced in the future, to carry out anti-rust treatment. Spray surface treatment to make it has quite good anti-corrosion ability, beautiful appearance, good waterproof effect, easy construction, economic and practical outstanding characteristics. Plastic sprayed blade barbed rope is a surface treatment method of spraying plastic powder on blade barbed rope in process.
6, the use of special formula and special UV absorbent, no fading, no yellowing, no peeling, no cracking, no foaming, no moth, the use cycle can be more than 30 years.
Galvanized electric welding mesh refers to the mesh made of zinc alloy material, because of its high strength, high hardness, beautiful appearance, bright color and other advantages, become used in residential communities. Traditional electric welding mesh using iron bars, aluminum alloy materials, need to use welding and other technology, and the texture is soft, easy to rust, single color.
Compared with galvanizing, hot-dip galvanizing has lower production cost and less environmental impact than galvanizing. Because the coating obtained is thicker, hot-dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for steel parts used in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, ocean exploration, metal structure, electric power transmission, shipbuilding and other industries.
The diameter of cold-drawn wire should conform to the contract, check whether the amount of zinc meets the requirements of the contract, check the tensile strength, and ask the factory to provide the corresponding inspection report. The wire factory introduces that the weight of a single coil of wire of different specifications should not be lower than the volume weight required by the contract, and record the value. No contacts are generated for each reel of wire. If there are contacts, no more than three contacts are generated for each reel. Each contact should be smooth surface treatment, the wire can not be pulled off from the contact, in line with customer packaging requirements.
Spring steel wire with high carbon quality carbon structural steel or carbon tool steel wire rod production, according to the use of spring strict control of its chemical composition, gas content and non-metallic inclusions. In order to reduce the appearance defect and decarbonization layer, the billet of consumption rod should stop the appearance grinding, and if necessary, stop the peeling.
