Good news! Salomon client bought 24tons galvalume coils from Wanzhi Steel, which has been manufactured and sent to Salomon. The customer indicated that after receiving our aluminized zinc coil, he would place an additional PPGL order for one cabinet. In color coating, Wanzhi has 2 color coating lines. The printing production line has an average monthly capacity of 10,000 tons for a single production line, 200,000 tons for two production lines, and more than 150 kinds of printing molds. Besides PPGL, we can also provide customers with color-coated galvanized coils, color-coated corrugated sheets, etc. You can contact us at any time to give you a quotation.

Galvalume steel coil is an important alloy material often used in our daily life. It is composed of aluminum zinc alloy structure, which is composed of 55% aluminum, 43% zinc and 2% silicon solidified at 600℃. The whole structure is composed of aluminum – iron – silicon – zinc, forming a dense quaternary junction crystal of an alloy.
|Coil weight||3-20 metric ton per coil|
|Surface treatment||Coated, chromated, oiled, anti-finger print|
|Package||Standard export package|
The surface of the galvalume coil is characteristic of smooth, flat and gorgeous star flowers, and the primary color is silver white. With strong corrosion resistance, heat resistance, reprocessability and electrical conductivity, widely used in construction, automobile, home appliances and other industries.
Buildings: roofs, walls, garages, sound walls, pipes and composite houses, etc.
Automobile: muffler, exhaust pipe, wiper accessories, fuel tank, truck box, etc.
Home appliances: refrigerator backboard, gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof belt, LED backlight, electric cabinet, etc.
Agricultural: pig house, chicken house, granary, greenhouse pipeline, etc.
Compared with aluminized zinc alloy, zinc coating has relatively active chemical properties, so its corrosion resistance is different. The test under the same outdoor conditions shows that the service life of aluminized zinc plate is more than four times that of galvanized plate.
The difference between galvanized sheets and galvalume sheets mainly lies in the difference of coating. The surface of galvanized sheet is evenly distributed with a layer of zinc material, which plays the role of anode protection for the base material, that is to say, the alternative corrosion of zinc material protects the use of the base material, and only when the zinc is completely corroded can it hurt the base material inside.
The surface coating of the aluminized zinc plate is composed of 55% aluminum, 43.5% zinc and a small amount of other elements. The surface of the aluminized zinc coating has a honeycomb structure at the microscopic level, and the honeycomb composed of aluminum contains zinc. In this case, although the aluminized zinc coating also plays the role of anode protection, But on the one hand due to the reduction of zinc content on the one hand due to the zinc material by aluminum packaging is not easy to electrolyze so the role of anode protection is greatly reduced, so once the aluminum zinc plate is cut, cut off the edge of the basic loss of protection will soon rust, so the aluminum zinc plate should be cut as little as possible, once cut after the application of anti-rust paint or zinc rich paint to protect the edge, To be able to prolong the service life of the plate.
● The use of alkaline medium under the condition of careful use of galvalume steel sheets.
● The roof of the galvalume building should have a certain slope, which is conducive to the drainage of water and avoid the deterioration of corrosion.
● Avoid direct contact with wet cement and wet wood, lead, copper, stone ink.
● Edge cutting plate should be used as far as possible to avoid cutting at the site.
● Processing, stacking should prevent moisture and high temperature caused by fingerprint film black.
● Galvalume steel sheets used for foaming bonding, small batch test should be carried out in the first use to prevent poor bonding performance.
● It is not recommended to wipe and clean the surface with alcohol solvent. If necessary, please conduct sample test first to avoid damage to the surface skin
