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 dimensions of steel coils used in the storage tank industry?
- Steel coils used in the storage tank industry come in various dimensions, depending on the specific requirements of the tank being manufactured. Generally, these coils are available in different sizes and thicknesses. The width of the steel coils can range from approximately 600 millimeters to 2,400 millimeters. Similarly, the length can vary from a few meters to tens of meters. The thickness of the coils can also differ, typically ranging from 1.5 millimeters to 10 millimeters or more. Factors such as the size and capacity of the storage tank, the material being stored, and the structural requirements of the tank determine these dimensions. Consequently, the tank manufacturer or designer would determine the specific dimensions for a given storage tank project, following industry standards and project specifications.
- Q:How do steel coils contribute to the marine equipment industry?
- Steel coils play a crucial role in the marine equipment industry by providing the necessary raw material for the construction of various marine equipment and structures. These coils, which are typically made of high-strength steel, offer several key contributions to the industry. Firstly, steel coils are used in the manufacturing of ships and boats. The high strength and durability of steel make it an ideal material for constructing the hulls, decks, and other structural components of vessels. Steel coils are employed to fabricate these parts, ensuring the necessary strength and integrity to withstand the harsh marine environment, including corrosion, waves, and impact. Furthermore, steel coils are essential in the production of offshore structures such as oil rigs, drilling platforms, and wind turbines. These structures require robust materials capable of withstanding extreme weather conditions, heavy loads, and corrosive saltwater. Steel coils provide the necessary strength and corrosion resistance needed for these applications, ensuring the safety and longevity of offshore installations. Steel coils also contribute to the marine equipment industry by being utilized in the construction of various marine components and equipment.

Automatic coil edge trimmers are fully automated machines that can handle high volume production, enhancing productivity and reducing labor requirements.
- Q:How are steel coils inspected for dimensional accuracy after processing?
- Steel coils are inspected for dimensional accuracy after processing using various methods such as measuring tape, calipers, laser scanners, or automated vision systems. These tools allow for precise measurements of the coil's width, thickness, and length, ensuring that it meets the required specifications.
- Q:How do steel coils contribute to corrosion resistance in products?
- Steel coils contribute to corrosion resistance in products by providing a protective layer that prevents direct contact between the steel surface and corrosive elements in the environment. The coil coating process involves applying a protective coating, such as zinc, to the steel surface, forming a barrier against moisture, chemicals, and other corrosive agents. This coating acts as a sacrificial layer, corroding in place of the steel, thereby extending the lifespan and enhancing the durability of the products.
- Q:What are the challenges in coil leveling for high-strength steel?
- Coil leveling for high-strength steel poses several challenges that need to be addressed in order to achieve optimal results. One of the main challenges is the inherent hardness and strength of the steel itself. High-strength steel is specifically designed to have enhanced mechanical properties, such as tensile strength and hardness, which make it more difficult to deform and shape. The high-strength nature of the steel requires specialized leveling equipment that can apply sufficient force to overcome its resistance to deformation. This may involve using stronger and more durable leveling rollers or increasing the pressure exerted during the leveling process. Failure to apply the appropriate force can result in incomplete leveling, leading to residual stress and potential dimensional inaccuracies in the final product. Another challenge in coil leveling for high-strength steel is the potential for springback. Springback refers to the tendency of the material to revert to its original shape after being deformed. High-strength steel is particularly prone to springback due to its higher elastic modulus. This can result in uneven leveling and dimensional variations in the coil. To mitigate springback, advanced leveling techniques may be employed, such as overbending or pre-bending the steel. Overbending involves bending the steel beyond the desired level, allowing it to spring back to the desired shape. Pre-bending, on the other hand, involves intentionally bending the steel in the opposite direction before leveling it, counteracting the effects of springback. These techniques require precise control and expertise to ensure accurate leveling. Additionally, high-strength steel often has a more pronounced yield point, which is the stress level at which permanent deformation occurs. This can make it more challenging to achieve consistent and uniform leveling throughout the coil. Proper adjustment of the leveling equipment and careful monitoring of the leveling process are necessary to address this challenge effectively. Furthermore, high-strength steel coils are often thinner and more sensitive to surface imperfections. The leveling process must be carefully regulated to avoid causing damage to the steel surface, such as scratches or indentations. This may involve utilizing softer leveling rollers or implementing protective measures, such as cushioning materials or coatings, to prevent surface defects. In summary, the challenges in coil leveling for high-strength steel revolve around its inherent hardness, springback tendencies, yield point behavior, and sensitivity to surface imperfections. Overcoming these challenges requires specialized equipment, advanced leveling techniques, precise control, and expertise to ensure accurate and high-quality leveling results.
