Zinc Coating Steel Coil Packing:
1. The base material of hot-dip galvanized steel sheet is cold-rolled sheet or hot-rolled sheet.
2 Hot-dip galvanized steel sheets are more corrosion-resistant than cold-rolled sheets.
3. The drawing performance of hot-dip galvanized steel sheets is not as reliable as that of cold-rolled sheets.
4. Hot-dip galvanized steel sheets are not as easy to weld as cold-rolled steel sheets, and the zinc layer is damaged during welding.
Hot-dip galvanizing involves degreasing, pickling, dipping, and drying the workpiece, then immersing it in the molten zinc solution for a certain period of time and then lifting it out. Cold galvanizing is also called electro-galvanizing. It uses electrolysis equipment to degrease and pickle the workpiece and put it into a solution composed of zinc salts, and connect it to the negative electrode of the electrolysis equipment; a zinc plate is placed opposite the workpiece and connected to the electrolysis equipment. Positive electrode, turn on the power, and use the directional movement of current from the positive electrode to the negative electrode, a layer of zinc will be deposited on the workpiece.
The difference between galvanized finished products: The surface of hot dip galvanizing is not as delicate and bright as cold-dip galvanizing, but the thickness of the zinc layer is dozens of times that of cold dip galvanizing. The anti-corrosion performance is also dozens of times that of electroplated zinc.

Hot dipped galvanizing has the following advantages over electro-galvanizing:
(1) It can produce a thicker coating, and has both a pure zinc layer and an iron-zinc alloy layer, so the corrosion resistance is better;
(2) The production efficiency of hot-dip galvanizing is particularly high; the time the parts stay in the hot-dip galvanizing tank generally does not exceed
(3) Compared with electroplating, hot-dip galvanizing has lower production costs and has less impact on the environment than electroplating;
(4) When plating plates, strips, wires, tubes and other profiles, the degree of automation is high.
Hot-dip galvanizing has better protective properties than electro-galvanizing, so it is an important protective coating for steel parts used in harsh working environments. Hot-dipped galvanised products are widely used in chemical equipment, petroleum processing, ocean exploration, metal structures, power transmission, shipbuilding and other industries. They are also used in agricultural fields such as pesticide sprinkler irrigation, greenhouses, and construction industries such as water and gas transmission, wire casings, scaffolding, and bridges. , highway guardrails, etc., they have been widely used in recent years.
