Galvanised Steel Metal Strips Roll
Product Description
Galvanized steel strip post-processing includes three aspects, phosphating, passivation, and pre-oiling. First, the passivation treatment of galvanized steel strips can improve the surface structure and gloss, improve the corrosion resistance and service life, and can improve the bonding strength of the coating and the base metal. The passivation treatment mainly adopts chromate passivation. Add some activators in the passivation solution, such as fluoride, phosphate, or sulfate, to get the chromate film thicker after the passivation. When fluoride in the passivation solution can reduce the surface tension of the steel strip, accelerate the film reaction, and can increase the chemical polishing effect so that the passive film is bright and delicate.

- Hot Galvanized Steel StripThe galvanized steel strip is a material that is coated with a layer of a layer called (zinc), which is a layer of hot-rolled, long, and narrow strips of steel. Hot dip galvanizing has the advantages of uniform coating, strong adhesion, long service life, and so on. The complex physical and chemical reactions occurred between the substrate and the molten bath of the hot dip galvanized steel pipe, and the corrosion resistance of the zinc-iron alloy layer was formed. Alloy layer and pure zinc layer, strip matrix. So its corrosion resistance ability is strong.
- Galvanized steel stripThe galvanized steel strip is a long and narrow sheet made with cold-rolled or hot-rolled steel. Through hot-dip galvanizing, a thick zinc layer is plated to offer a uniform surface. Also, after complex physical and chemical reactions, a corrosion-resistant zinc-iron alloy layer will be formed between the substrate and zinc molten bath. Generally, the steel strips are supplied in coils. According to the different base metals, you can find cold-rolled strips and hot-rolled strips.
