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 manufacturing defects in steel coils?
- There are several common manufacturing defects that can occur in steel coils, including surface imperfections such as scratches, pits, or dents, dimensional inconsistencies such as uneven thickness or width, edge defects like burrs or cracks, and internal defects such as inclusions or voids. These defects can impact the quality and performance of the steel coils, and manufacturers strive to minimize these issues through quality control measures and inspections.
- Q: What are the challenges in coil recoiling?
- Coil recoiling, also known as coil winding, can pose several challenges depending on the specific application and requirements. Some of the common challenges in coil recoiling include: 1. Precision and accuracy: Achieving precise and accurate winding is crucial for optimal coil performance. Maintaining consistent tension throughout the winding process, ensuring proper alignment, and controlling the speed are essential to avoid variations in the coil's electrical properties. 2. Wire management: Handling the wire during the recoiling process can be challenging. The wire may be delicate, prone to tangling, or have specific handling requirements, such as being magnetically or thermally sensitive. Proper wire management techniques, such as tension control, wire guide systems, and spooling mechanisms, need to be employed to prevent wire damage and ensure uniform winding. 3. Space constraints: In many applications, coils need to fit within specific space limitations. Designing and winding coils to fit compact spaces can be challenging, especially when considering the required number of turns, wire size, insulation, and any additional components or structures that may need to be incorporated. 4. Material selection: Selecting the appropriate wire and insulation material is crucial for coil performance and longevity. Factors such as electrical conductivity, thermal properties, mechanical strength, and chemical resistance need to be considered to ensure the coil can withstand the operating conditions and environmental factors it will be exposed to. 5. Heat dissipation: Coils often generate heat during operation, especially in high-power applications. Efficient heat dissipation is essential to prevent overheating and ensure the longevity of the coil. Designing the coil with proper ventilation, utilizing cooling mechanisms, or integrating heat sinks are some of the techniques used to address this challenge. 6. Quality control: Ensuring consistent quality in coil recoiling can be challenging due to factors such as variations in wire properties, operator skill, equipment calibration, and environmental conditions. Implementing robust quality control measures, such as conducting regular inspections, performing electrical tests, and monitoring process parameters, is necessary to maintain consistent coil performance. Overall, coil recoiling requires attention to detail, precision, and adherence to specific requirements to overcome the challenges and produce high-quality coils that meet the desired performance criteria.
- Q: PLS tell me all Foam Steel Characteristics and use?Thanks
- Foam steel [often steel foam] is used in applications that require light weight but high rigidity and strength. Watertight doors on modern ships are often made of foam steel. Pressure doors on aircraft are possible uses. As we keep striving for lighter weights in cars, foam steel might have some useful applications in bodies. There is a technical paper online that is in .pdf format that has a good discussion of the process and characteristics of foam steel.
- Q: How are steel coils used in the manufacturing of industrial machinery?
- Steel coils are used in the manufacturing of industrial machinery as they serve as the primary raw material for various components such as frames, casings, gears, and structural supports. These coils are typically cut, shaped, and welded to create the desired machine parts, ensuring strength, durability, and precision in the final product.
- Q: Can steel coils be embossed?
- Yes, steel coils can be embossed. Embossing is a process that involves creating raised or recessed designs on a material's surface, and it can be done on various materials, including steel.
- Q: How are steel coils used in the manufacturing of wires?
- Steel coils are used in the manufacturing of wires by being fed into wire drawing machines where they are elongated and reduced in diameter to the desired thickness. The steel coils provide a continuous supply of raw material, ensuring a seamless production process for manufacturing wires of various sizes and applications.
- Q: I need steel toe shoes for a workplace, where can I get them?I live in Surrey,UK.
- by on the internet or ppe clothing shops
- Q: How are steel coils tested for dimensional accuracy?
- Steel coils are typically tested for dimensional accuracy using various methods such as measuring the width, thickness, and diameter of the coil. This can be done using specialized instruments like calipers, micrometers, and laser scanners to ensure the coil's dimensions meet the required specifications.
