Galvanized coil, the thin steel plate is dipped into the melted zinc tank, so that its surface adheres to a layer of zinc thin steel plate. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously dipped in the plating tank with melted zinc to make galvanized steel plate. Alloyed galvanized steel sheet. This steel plate is also made by hot dipping, but immediately after the tank is heated to about 500 ° C, so that it generates an alloy coating of zinc and iron. This galvanized coil has good coating adhesion and weldability.

The production process of galvanized coil mainly includes the following steps: steel coil pickling, cleaning, pretreatment, baking, zinc dipping, cooling, coil formation and so on. Put the steel coil to be galvanized into the acid solution for pickling, after pickling, the surface of the steel coil will remain acid, chloride ions and other harmful substances, need to use water to wash, put the cleaned steel coil into the pretreatment tank for surface treatment, the surface of the steel coil will have a protective film, the steel coil into the molten zinc solution for dipping and plating, in order to achieve the ideal galvanized quality. Cooling is carried out to make the zinc layer on the surface of the steel coil solidify quickly to ensure the quality of the coating.

In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
