Galvanized Steel Sheet raw steel material from Big Mill with reliable quality.
Construction, packaging, railway vehicles, agricultural machinery and daily life.
Oiled/dry, Skin-pass/Nonskin-pass, Regular/Minimize/Zero Spangle
Application: with excellent cold bending molded manufacturablity, good decoration effect, strong anti-corrosion ability, galvanized steel coils and sheets are also pollution-free and easily recycled. Accordingly, they can be used as final products and basic plates of color coated steel coils and widely applied in construction, home appliances, decoration, ect.

After the chemical reaction between aluminum and oxygen in the air, A layer of strong and dense oxide film will be generated. This layer of aluminum oxide film preservation became "coat", the internal aluminum is difficult for them to oxygen in the air to oxidation, so aluminum is placed in the atmosphere a year, which is less than the depth of corrosion of thousands of hours one millimeter. If the same time into the aluminum and steel containing 3% of sodium chloride and 1% of the hydrogen chloride in the container, the corrosion test of 70 hours, the average weight loss of steel per square centimeter 11.07 mg in weight loss of aluminum average of 0.675 milligrams per square centimeter, which proves the corrosion resistance of aluminum is generally much higher than the steel. However, the natural oxide film of aluminum, there are still shortcomings thin and soft, corrosion is not very strong, so that the service life of corrugated sheet aluminum untreated generally only about 20 years. If aluminum by chemical oxidation (i.e., at a certain temperature of the aluminum oxide surface cleaning and liquid oxygen in a chemical reaction) or electrochemical oxidation (i.e. the aluminum into the electrolyte, in the role of the applied current and oxygen ions the method of a direct reaction of water with aluminum surface cleaning) are processed, on the surface of the aluminum layer will generate 0.025 to about 0.05 millimeters thick and hard and even more some of the oxide film, so as to further improve the corrosion resistance of aluminum performance. After aluminum corrugated sheets thus treated, the service life of up to 60 years. Aluminum corrugated sheets can also be a variety of bright colors, it is possible to make the building more beautiful.
