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 Aluminum Zinc Rolled Coil for Construction Roof
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 Aluminum Zinc Rolled Coil for Construction Roof
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 coil width tolerances?
- The common coil width tolerances vary depending on the industry and specific application. However, typical coil width tolerances range from +/- 0.005 to 0.030 inches.
- Q: How do steel coils contribute to the construction sector?
- Steel coils play a crucial role in the construction sector in various ways. Firstly, steel coils are extensively used in the manufacturing of structural components such as beams, columns, and trusses. These components form the backbone of buildings and provide the necessary strength and stability to the structure. Steel coils are processed and shaped into these structural components, ensuring that they can withstand the heavy loads and forces experienced in construction. Additionally, steel coils are utilized in the production of reinforcement bars, commonly known as rebars. These rebars are embedded within concrete structures, enhancing their tensile strength and preventing cracks or fractures. This reinforcement is essential in constructing durable and resilient infrastructure, from bridges and highways to buildings and stadiums. Moreover, steel coils find applications in the fabrication of roofing and cladding materials. The coils are processed and formed into corrugated sheets or panels, which are then used to cover roofs and walls. These steel roofing and cladding materials offer excellent protection against environmental factors such as rain, wind, and UV radiation. Furthermore, they provide thermal insulation, fire resistance, and aesthetic appeal to the constructed buildings. Furthermore, steel coils contribute to the construction sector through their use in the production of various mechanical components, including pipes, tubes, and fittings. These components are essential for plumbing, heating, ventilation, and air conditioning systems in buildings. Steel's durability, corrosion resistance, and ability to handle high-pressure conditions make it an ideal material for these applications. The versatility, strength, and durability of steel coils make them indispensable in the construction sector. They provide the necessary materials for constructing robust structures, reinforcing concrete, and producing essential components. Steel coils not only contribute to the safety and longevity of buildings but also play a vital role in the overall development and growth of the construction industry.

Additionally, steel coils are utilized in the manufacturing of household appliances, such as refrigerators and washing machines. Their versatility, strength, and durability make steel coils a crucial material for many industrial applications.
- Q: Can steel coils be coated with noise-reducing materials?
- Yes, steel coils can be coated with noise-reducing materials.
- Q: What are the different coil edge options?
- The different coil edge options include open coil, continuous coil, offset coil, and pocket coil.
- Q: How are steel coils used in the manufacturing of tubes?
- Steel coils are used in the manufacturing of tubes by being processed through a series of steps such as slitting, forming, and welding. These coils are slit into narrower strips, which are then formed into a cylindrical shape and welded together. This process allows for the efficient production of seamless or welded tubes, which can be used in various industries such as construction, automotive, and oil and gas.
- Q: How are steel coils protected from condensation?
- Steel coils are protected from condensation by applying a layer of corrosion-resistant coating, such as zinc or a polymer, on the surface. This coating acts as a barrier, preventing moisture from coming into direct contact with the steel and reducing the chances of condensation occurring. Additionally, steel coils are often stored in controlled environments with controlled humidity levels to further minimize the potential for condensation.
