Zinc Aluminum Steel FAQS
What is zinc aluminum steel?
zinc aluminum steel is an alloy-coated steel sheet widely used in building materials, home appliances, automobiles, environment, machinery, ships and many other fields.
zinc aluminum steel is composed of aluminum-zinc alloy structure, which is composed of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600°C. The entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal An alloy coated steel plate.
What are the characteristics of zinc aluminum steel?
zinc aluminum steelhas many excellent characteristics:
The corrosion resistance of “galvanized steel coil” is mainly due to the protective function of aluminum. When the zinc is worn away, the aluminum forms a dense layer of aluminum oxide, which prevents the corrosion-resistant substances from further corroding the interior.
The aluminum-zinc alloy steel plate has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is very similar to the high-temperature oxidation resistance of the aluminized steel plate. It is often used in chimney pipes, ovens, illuminators and fluorescent lamp shades.
The heat reflectance of galvanized steel sheet is very high, which is twice that of galvanized steel sheet. People often use it as heat insulation material.
Because the density of 55% AL-Zn is smaller than that of Zn, the area of galvanized steel sheet is more than 3% larger than that of galvanized steel sheet when the weight is the same and the thickness of the gold plating layer is the same.
What are the applications of zinc aluminum steel?
Construction: roofs, walls, garages, sound insulation walls, pipes and prefabricated houses, etc.
Automobile: mufflers, exhaust pipes, wiper accessories, fuel tanks, truck boxes, etc.
Household 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.
What are the uses of zinc aluminum steel?
Storage: It should be stored indoors such as warehouses, kept dry and ventilated, and not placed in acidic climate for a long time. When storing outdoors, it should be protected from rain to avoid oxidative stains caused by condensation. Transportation: To avoid external impact, SKID should be used to support steel coils on the transportation vehicle, to reduce stacking, and to take rainproof measures. Processing: COILCENTER needs to use the same lubricating oil as the aluminum plate when shearing. When it is necessary to drill holes or cut galvanized steel sheets, it is necessary to remove scattered iron filings in time.
What are the differences between zinc aluminum steel and galvanized sheet?
The difference between the zinc aluminum steel and the galvanized sheet is mainly the difference in the coating. The surface of the zinc aluminum steel is evenly distributed with a layer of zinc material, which acts as an anodic protection for the base metal, 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 zinc aluminum steel 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 zinc aluminum steel 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 panels is extended.
What is the processing process of galvanized sheet?
Pre-treatment: After the cold-rolled coil comes to the galvanizing workshop, it passes through the uncoiler, the degreasing section and the reduction furnace to clean the steel coil and restore its components to the extent that it can be galvanized.
Central section: The most critical technology is this step. After passing through the zinc pot, a layer of zinc is coated on the surface of the steel plate. It will look beautiful immediately after coming out of the zinc pot, and then it will be cooled and shaped by the cooling tower.
Post-processing: After various processes, the steel plate finally reaches the post-processing stage. After finishing, straightening, and passivation, the steel plate is finally rolled onto the winder to form our final product.
The corrosion resistance of 55% galvanized sheet is 2 to 6 times that of galvanized sheet. Because of its superior corrosion resistance and processing performance, it can be directly used as building roof panels, civil and home appliance back panels, etc., and is also widely used For color coated substrates. The smooth commissioning of galvanized sheet not only enriches the company’s product categories, but also provides more flexible options for future market layout and strategic planning.
What are the advantages of zinc aluminum steel?
The 55%zinc aluminum steel has the protective function of barrier layer from aluminum and the sacrificial protective function of zinc. When zinc is cut and scratched, aluminum will form an insoluble oxide layer to play a protective role. In addition, the density of galvanizing is low, and the coating thickness of the same weight is much thicker than that of galvanizing. In addition to corrosion resistance and high temperature resistance, the 55%zinc aluminum steel has good reflectivity, and the paint coating has good adhesion. There are also 55% galvanized sheets with a variety of spangles, the surface of which is beautiful, and suitable for external use.
What is zinc aluminum magnesium coated steel?
Zinc aluminum magnesium coated steel is a new type of corrosion-resistant steel. It is made by hot-dip coating a layer of aluminum-zinc alloy on the surface of cold-rolled steel sheet.

What are the Disadvantages of Zinc Aluminum Magnesium Coated Steel?
Zinc aluminum magnesium coated steel is a type of galvanized steel that has been treated with an alloy of zinc, aluminum, and magnesium. This coating is applied to create a barrier against corrosion and rust. The advantages of this process include a longer lifespan for the steel and greater protection against the elements. However, there are also some disadvantages to consider before using this material.
One potential disadvantage of zinc aluminum magnesium coated steel is that it may be more expensive than other types of galvanized steel. This is because the process of applying the coating is more complex and requires specialized equipment. Additionally, the materials used in the coating are typically more expensive than those used in other methods of galvanization.
Another downside to this type of steel is that it can be more difficult to work with. The coating can make the surface of the metal harder to cut, weld, or bend. This can make it challenging to fabricate parts or constructions from this material. As a result, it is important to consult with experts before attempting to use zinc aluminum magnesium coated steel in any project.
What is the process of Zinc Aluminum Magnesium Coating Steel?
The process of zinc aluminum magnesium coating steel is a multi-step process that begins with the cleaning of the steel. The steel is then dipped in a hot-dip galvanizing bath, which provides the zinc aluminum magnesium coating.
How is zinc aluminum magnesium coated steel heat treated?
Zinc aluminum magnesium coated steel is heat treated by first being passed through a hot-dip process, in which the steel is dipped into a bath of molten zinc. This gives the steel a thin layer of zinc on its surface. The steel is then cooled and passed through an annealing process, which helps to improve its ductility. Finally, the steel is passed through a hot-dip galvanizing process, in which it is coated with a layer of zinc and aluminum.
Are there any common products that use zinc aluminum magnesium coated steel?
Magnesium is the primary element in this coating and it provides many benefits. For instance, it increases the corrosion resistance of the steel.
