Galvanized steel coil: Galvanized steel sheet through continuous hot-dip coating to improve their service life.
Technology: 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.

Galvanized steel
The thickness of the zinc layer is large: usually the thickness of the zinc layer can reach 60-80 microns, or even thicker, so the anti-corrosion performance is excellent.
Strong adhesion: The zinc layer forms a good metallurgical bond with the steel plate substrate, with strong adhesion and resistance to detachment.
Widely applicable: Suitable for outdoor buildings, bridges, highway guardrails and other environments that require long-term corrosion resistance.

1.What is Galvanized Steel HS Code?
721049,Check tariffs before ordering from China.
2.The service life of galvanized steel coils?
The life of galvanized steel coil depends on the end application and environment, as well as the weight of zinc. For example,the life of Z275 galvanized roof in a marine environment is 5 years.The life of Z180 cable tray in an indoor environment is 15 years.
3.The price of galvanized steel coils?
The price of galvanized steel coil depends on the raw material hot-rolled, the zinc weight, and the width and thickness of the coil.
4.Galvanized steel coil could be oiled?
Yes, it could be oiled.8-20g per square meters. Oiling can prevent the oxidation of galvanized sheets in a short time.
5.Does the product have quality inspection before loading?
Of course, all our products are strictly tested for quality before packaging, and unqualified products will be destroyed.weaccept the third party inspection absolutely.
6.What product information do I need to provide?
You need to provide the grade, width, thickness, coating and the number of tons you need to purchase.
