Hot dip galvanizing has been used for more than 150 years, and its principle has not changed so far. The steel structure should be fully immersed in zinc at one time to achieve uniform galvanized film structure. If it is too long or too wide to be dipped twice, the zinc layer at the joint will appear rough, too thick and so on. In addition, if the single weight of steel structure is too heavy, it will make its operation difficult if it exceeds the load of galvanizing equipment. Therefore, the communication with the hot dip galvanizing factory in advance.

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.

In order to make the zinc content of steel wire stable in the future, and maintain its uniformity, as far as possible to reduce the zinc content, and effectively reduce zinc consumption to the actual work, the following measures are proposed by the wire factory:

Many customers are in great need of galvanized barbed rope when they decide to purchase it, and the barbed rope specification determines the length of the later installation.

Cold galvanizing is also called electric galvanizing. It is the use of electrolytic equipment to remove oil, pickling, and then put the pipe into the solution of zinc salt, and connect the anode of the electrolytic equipment, place zinc plate on the opposite side of the pipe, and connect the positive pole of the electrolytic equipment to the power supply. A layer of zinc is deposited on the pipe fitting by directional movement of an electric current from the positive pole to the negative pole. Cold plated pipe fitting is processed before galvanizing.

Large roll galvanized wire is processed by low carbon steel wire rod, through drawing molding, pickling rust removal, high temperature annealing, cooling and other processes. Large roll galvanized wire electroplating temperature should be controlled in 30-50℃. Because of the strong corrosivity of chloride ions in bath, quartz glass heater is generally used. Continuous production does not need heating, but need cooling cooling.

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.

The wire used for wire mesh is made of low carbon steel wire, medium carbon steel wire, high carbon steel wire, stainless steel wire and other materials woven or welded. Production technology: general braid, embossed braid and spot welding type. If the steel wire as the material, after the equipment processing into a network, so called wire mesh.
