Structure of Al-Zinc coated steel coil
Description of Aluminum Zinc Rolled Coil
Aluminum zinc coils is a kind of coated steel coil/sheet. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In its coating, Al accounts for about 55%, Si 1.6%, while the remaining is Zn. Aluminum zinc coils enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.
Main Feature of Al-Zinc coated steel coil
1.Corrosion resistance: It mainly depends on the aluminum protection. When the zinc being worn, the aluminum will form a dense layer of aluminum oxide, resist corrosion material to prevent further corrosion inside.
2. Heat resistance: Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperatures over 300 centigrade, and is similar with aluminized steel high temperature oxidation resistance. It often used in chimney pipes, ovens, fluorescent lighting device and the device cover.
3. Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to make insulation materials.
4. Economy: Because density of 55% AL-Zn is smaller than the density of Zn, so in the same weight and thickness of Galvanized zinc layer, aluminum-zinc steel plate is larger area more than 3% of galvanized steel sheet.
Applications of Al-Zinc coated steel coil
1. Construction and building: roofing; ventilating duct; handrail; partition panel;etc.
2. Electric appliance: refrigerator; washing machine; refrigerator; DVD;etc.
3.Transportation: oil tank; road sign; etc.
4.Agriculture:barn; etc.
5.Others:vending machine; game machine; etc.

- Q: What are the common methods of packaging steel coils for transportation?
- There exists a variety of conventional techniques for packaging steel coils for transportation. One frequently employed approach involves the utilization of steel strapping or bands to fasten the coils together. This method entails tightly encircling the coils with steel bands and securing them using metal buckles or seals. The strapping serves to maintain the coils in position and prevent any shifting or rolling during transportation. Another popular technique entails the use of wooden pallets or skids to stack and transport the steel coils. The coils are positioned onto the pallets and secured with steel strapping or bands. This approach ensures stability and facilitates easy handling and loading onto trucks or other means of transportation. Furthermore, certain steel coils are enclosed within wooden crates or boxes. These crates are typically constructed from robust and durable wood and are designed to shield the coils from external impacts or damage during transportation. To enhance strength and stability, the crates are frequently reinforced with steel bands or strapping. In addition to the aforementioned methods, specialized containers or units are employed to package certain steel coils. These containers are specifically engineered to accommodate and secure steel coils for transportation. They often possess integrated mechanisms or features that facilitate the loading and unloading of the coils in a safer and more efficient manner. It is important to acknowledge that the particular method of packaging steel coils for transportation can vary depending on factors such as the size and weight of the coils, the mode of transportation, and any specific requirements or regulations that may be in effect.
- Q: What are the dimensions of steel coils used in the appliance industry?
- Steel coils used in the appliance industry can have varying dimensions depending on the specific application and requirements. However, a typical range for these coils is a thickness of 0.015 to 0.035 inches (0.38 to 0.89 millimeters), a width of 24 to 36 inches (61 to 91 centimeters), and a weight between 1,500 to 10,000 pounds (680 to 4,535 kilograms). These dimensions are chosen to facilitate efficient handling, transportation, and processing during the appliance manufacturing process. It is important to verify these dimensions with the manufacturer or supplier for accurate and current information.
- Q: How do the sandpaper grits compare with different coarse levels of steel wool? For example, I'm finishing a homemade entertainment center, and using a tinted polyurethane, and it says to use 000 grade steel wool, but mine is #3, could I use some sanpaper instead, and what grit?
- Steel wool and wax is for the final buff after the finish coat. Sanding will scratch the finish and should only be done before the finish coat. Steel wool and wax have been used as the final finish to remove rough areas and buff the finish for a long time.
- Q: who are the 7 best steel guitar players ever?
- Steel Guitar Players
- Q: How do steel coils contribute to the transportation industry?

- Q: How are steel coils used in the manufacturing of exhaust manifolds?
- Steel coils are used in the manufacturing of exhaust manifolds by being shaped and formed into the desired design and dimensions of the manifold. The coils are typically cut, bent, and welded together to create the necessary shape and structure of the exhaust manifold.
- Q: Can steel coils be coated with zinc-nickel alloy?
- Yes, steel coils can be coated with a zinc-nickel alloy. Zinc-nickel alloy coating provides excellent corrosion resistance and is commonly used in various industries including automotive, construction, and manufacturing.
- Q: What are the different types of steel coil handling equipment?
- Some different types of steel coil handling equipment include coil lifters, coil tongs, coil grabs, coil hooks, coil transfer cars, and coil upenders. These equipment are designed to safely lift, transport, and rotate steel coils during various industrial processes.
- Q: What are the common processing defects in steel coils?
- The common processing defects in steel coils include surface imperfections such as scratches, dents, and stains, as well as edge wave, coil set, camber, and crossbow. Other defects may include coil breaks, oil spots, rust, and uneven thickness or width variation.
- Q: How are steel coils used in the manufacturing of automotive fuel tanks?
- Steel coils are used in the manufacturing of automotive fuel tanks as they are shaped and welded to form the structure of the tank. The coils provide strength and durability to the tank, ensuring it can withstand the pressure and impact of the fuel.
