| Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel, Zinc-alu steel, aluminized zinc steel (aluzinc steel), SGLC, The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at 600 ~C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a compact quaternary crystal alloy. The surface of the galvalume steel sheet is characterized by smooth, flat and gorgeous stars, and its base color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of galvalume steel sheet is up to 25a, and its heat resistance is good. It can be used in high temperature environment at 315 C. The adhesion between coating and paint film is good, and it has good processing performance. It can be punched, sheared and welded. The surface conductivity is very good. |
The surface of the galvanized steel plate has a unique smooth, flat and gorgeous star flower, and the base color is silvery white. The special coating structure makes it have excellent corrosion resistance. The normal service life of the galvanized sheet can reach 25a, the heat resistance is very good, and it can be used in a high temperature environment of 315°C; the adhesion between the coating and the paint film is good, and it has good processing performance, and can be stamped, cut, welded, etc.; The surface conducts electricity very well.
The coating composition is composed of 55% aluminum, 43.4% zinc and 1.6% silicon respectively by weight. The production process of galvanized steel sheet is similar to that of galvanized steel sheet and aluminum-coated sheet, and it is a continuous fusion coating process. Galvalume-coated steel sheets with 55% Al-Zn alloy coating have superior corrosion resistance compared to galvanized steel sheets 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 also color-coated products have excellent adhesion and flexibility.
We can also produce the Pre-painted galvalume steel coil as customer needs.
Construction: roofs, walls, garages, acoustic walls, pipes and prefabricated houses, etc.
Automotive: mufflers, exhaust pipes, wiper accessories, fuel tanks, truck boxes, etc.
Home appliances: refrigerator back panel, gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof belt, LED backlight, electrical cabinet, etc. Agricultural use: pig house, chicken house, granary, greenhouse pipes, etc.
Others: heat insulation cover, heat exchanger, dryer, water heater, etc.The difference between galvanized sheet and galvanized sheet:
The difference between the galvanized sheet and the galvanized sheet is mainly the difference in the coating layer. The surface of the galvanized sheet is evenly distributed with a layer of zinc material, which acts as an anodic protection for the base material, that is, an alternative corrosion protection for the zinc material. Without the use of the base metal, only when the zinc is completely corroded can the base metal inside be damaged.
The surface coating of the galvanized sheet is composed of 55% aluminum, 43.5% zinc and a small amount of other elements. Microscopically, the surface of the galvanized coating is a honeycomb structure, and the "honeycomb" composed of aluminum contains zinc. In this case, although the aluminum-zinc coating also plays the role of anodic protection, on the one hand, due to the reduction of zinc content, on the other hand, the effect of anodic protection is greatly reduced because the zinc material is wrapped in aluminum and is not easy to be electrolyzed. The galvanized sheet is cut, and it will rust soon when the cut edge basically loses its protection. Therefore, the galvanized sheet should be cut as little as possible. Once cut, the edge should be protected with anti-rust paint or zinc-rich paint to make it The service life of the plate is extended
inan Zunkai Group founded in 2002, with five branch companies and is well-funded. Our annual sales nearly one billion, about 300,000 tons steel.
