Hot Dipped Galvanized Steel Coil Hot Dipped Galvanized Steel Coil

Hot dipped galvanized steel coil is coated with a layer of zinc to prevent corrosion and prolong service life. Among many protective measures for matrix steel, hot-dip galvanizing is very effective. When zinc is in the liquid state, it is coated onto the surface of matrix steel by complicated physical and chemical effects. At the same time, zinc iron alloy coating is also formed. This method is very suitable for highly corrosive environment of strong acid, alkali mist because matrix steel will have strong corrosion resistance.

The principle of this method is as follows. In the first step, iron base is melted by zinc liquid and zinc - iron alloy phase layer is formed. In the second step, zinc ions in the alloy layer diffuse toward the base and form zinc iron miscible layer. After that, alloy layer is enveloped by zinc layer.

With beautiful appearance and corrosion resistance, hot dipped galvanized steel coil is widely used in many fields, such as industry, agriculture, construction and transportation. To be more specific, it can be extensively used in chemical equipment, oil processing, ocean exploration, metal structure, power transmission, shipbuilding, sprinkler irrigation, warm room, water and gas transmission, wire sets tube, scaffolding, housing and bridge, etc.

There are many outstanding features of hot dipped galvanized steel coil. In the first place, it has a thick layer of pure zinc, so contact between matrix steel and corrosive solutions is avoided, thus protecting it. In the second place, it has a dense iron - zinc alloy layer, so it has unique corrosion resistance in sea salt atmosphere and industrial atmosphere. Thirdly, this product has strong wear resistance because it has a combination of solid zinc - iron miscible. In addition to that, hot dipped galvanized steel coil can be processed by many processing without damage, including cold punching, rolling, drawing, bending because of good ductility of zinc and solid adhesion between alloy layer and matrix steel. Hot-dip galvanizing, equal to annealing, can effectively improve the mechanical properties of matrix steel, eliminate stress of mold welding and facilitate lathe work. Lastly, pure zinc layer has ductility and flexibility.
