0.35mm-2mm Prime Hot Dipped Dx51d Z275 Zinc Coated Galvanized Steel Coil Price
Galvanized steel coil, immersing the thin steel plate in the molten zinc bath, and adhering a layer of zinc thin steel plate on the surface. It is mainly produced by the continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the zinc-melted plating tank to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also made by the hot-dip method, but it is heated to about 500 °C immediately after exiting the tank to form an alloy film of zinc and iron. This galvanized steel coil has good paint adhesion and weldability.

◆ 1. Pre-Treatment Process
Some rolling oil and other contaminants remain on the surface of cold rolled steel sheets following processing. These are removed by passing the electrically charged sheet through an alkaline solution which induces an electrochemical reaction.
◆ 2. Annealing
The material properties of the pre-treated steel sheet can be altered and improved through recrystallization during the annealing process.
◆ 3. Hot-Dip Galvanizing
After passing through the annealing furnace, steel sheets are dipped into a zinc pot where molten Zn is coated onto the surface. The desired coating weight is achieved by removing excess zinc before solidification with high-pressure air from an air knife.
◆ 4. Galvannealing
The surface of a steel sheet, after the air knife, can be coated with a zinc compound prior to reheating in an annealing process. Zn atoms diffuse into the Fe to create a Zn-Fe series alloy.
◆ 5. SPM & Chemical Treatment
In order to achieve a flat surface and an elegant finish, the steel sheet is processed with a skin pass mill. In order to prevent the white rust, which often forms on the surface of activated zinc, and to improve corrosion resistance, the surface is coated with a Cr-free resin.
◆ 6. Inspection & Coiling
Located at the line’s exit section are a side trimmer, inspection table, oil coating machine and coiling equipment. At this station, all products are inspected and judged relative to material specifications required by the customer.
