The surface of the GL steel sheet is uniquely smooth, flat and gorgeous with star-shaped patterns, and the base color is silver-white. The special coating structure gives it excellent corrosion resistance. The normal service life of the galvanized steel sheet can reach 25 years, and it has good heat resistance and can be used in a high temperature environment of 315°C; the coating has good adhesion to the paint film, has good processing performance, and can be stamped, sheared, welded, etc.; the surface conductivity is very good.
The coating composition is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon by weight. The production process of galvanized steel sheet is similar to that of galvanized steel sheet and aluminum-plated sheet, which is a continuous molten coating process. The 55% aluminum-zinc alloy-coated galvanized steel sheet has superior corrosion resistance compared to the galvanized steel sheet of the same thickness when both sides are exposed to the same environment. The 55% aluminum-zinc alloy-coated galvanized steel sheet not only has good corrosion resistance, but the color-coated product has excellent adhesion and flexibility.

1. Hot rolled coils are made of continuous casting slabs or initial rolled slabs. They are heated in a step-beam heating furnace, descaled with high-pressure water, and then enter the rough rolling mill. The rough rolled material is cut and then enters the finishing mill for computer-controlled rolling. After the final rolling, it is cooled by laminar flow (cooling rate is controlled by computer) and coiled by a coiler to become a straight roll.
2. Cold Rolled Coils Different from hot-rolled coil, cold-rolled coil refers to the steel strip that is directly rolled to a certain thickness by rollers at room temperature and then rolled into a whole roll by a coiler. Compared with hot-rolled coil, cold-rolled coil has a brighter surface and higher finish, but it will produce more internal stress and is often annealed after cold rolling.
3. Galvanized coils are made by dipping thin steel sheets into a molten zinc bath to make a layer of zinc adhere to the surface of the thin steel sheet. It is mainly produced by continuous galvanizing process, that is, the rolled steel sheets are continuously dipped into a molten zinc bath to make galvanized steel sheets; alloyed galvanized steel sheets. This type of steel sheet is also made by hot dip method, but after leaving the bath, it is immediately heated to about 500ºC to form an alloy film of zinc and iron. This type of galvanized coil has good coating adhesion and weldability.
4.Color coated steel coil is a product made of hot-dip galvanized steel sheet, hot-dip aluminum-zinc steel sheet, electro-galvanized steel sheet, etc. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coating are applied on the surface, and then cured by baking. It is named after the colored steel coils coated with various colors of organic coatings, and is referred to as color coated steel coils.
