Galvanized steel strip coil: Galvanized steel strip obtained by slitting galvanized steel coil into strips.
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.

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.
