Description of Prepainted Aluminum Zinc Rolled Coil for Construction roof
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 Prepainted 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 Prepainted 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.

- Q: How are steel coils used in the manufacturing of engine mounts?
- Steel coils are used in the manufacturing of engine mounts as they provide strength, durability, and flexibility. These coils are typically used as the main component of the mount, providing the necessary support and stability for the engine. The steel coils are designed to absorb and dampen vibrations, ensuring smooth operation and minimizing the transfer of engine vibrations to the vehicle.
- Q: What is the role of steel coils in the manufacturing of agricultural machinery?
- Steel coils are used in the manufacturing of agricultural machinery to provide strength, durability, and structural integrity to the equipment. They are typically used to form the main body and framework of the machinery, ensuring it can withstand heavy loads, harsh environments, and repetitive use. Additionally, steel coils are often used to fabricate specific components, such as blades, cutting edges, and structural supports, which are crucial for the proper functioning of agricultural machinery in various farming operations.
- Q: What are the main factors that affect the corrosion resistance of steel coils?
- The main factors that affect the corrosion resistance of steel coils include the composition of the steel, the presence of impurities, the type and thickness of the protective coating, exposure to corrosive environments (such as moisture, chemicals, and salt), and the presence of physical damage or scratches on the surface of the coils.
- Q: What is the lifespan of coated steel coils?
- The lifespan of coated steel coils may differ based on various factors, including the coating type and quality, the environmental conditions they face, and the care and maintenance provided. Typically, high-quality coated steel coils can last 25 to 50 years or longer. However, it is important to note that this estimate is not definitive and the actual lifespan may vary. To significantly extend the lifespan of coated steel coils, it is essential to conduct regular inspections, ensure proper installation, and perform timely maintenance. Moreover, exposure to severe weather, corrosive environments, and improper handling can potentially shorten the lifespan.

- Q: I just got my Daewoo K2 in 5.56 and i know they are tough and reliable but how well will it fair with steel rounds. I know shooting brass is better for any gun but what kind of extra wear and tear would i be looking at with shooting steel. Also what about reloading steel. Is it recomended. I would not even be asking this but steel is far cheaper than brass ammo, and i need to save some money.
- It would actually cost you more to reload steel.
- Q: How do steel coils contribute to the packaging industry?
- Steel coils play a crucial role in the packaging industry by providing a durable and versatile material for packaging various products. The use of steel coils in packaging ensures the protection and preservation of goods during transportation and storage. One way steel coils contribute to the packaging industry is through their strength and durability. Steel is known for its high strength-to-weight ratio, making it an ideal material for packaging heavy and bulky items. Steel coils can withstand significant pressure and impact, ensuring that goods remain intact and undamaged throughout the supply chain. This strength also allows for the stacking of packages, optimizing storage space and reducing the risk of damage. Furthermore, steel coils are highly resistant to corrosion and moisture. This property is particularly important in the packaging industry as it helps protect goods from environmental factors that could potentially compromise their quality. Steel coils can be coated or treated to enhance their corrosion resistance, ensuring that packaged products remain in pristine condition. Steel coils are also versatile and can be easily customized to suit specific packaging requirements. They can be cut and shaped into various forms, such as sheets, straps, or bands, to secure and protect different types of products. Additionally, steel coils can be easily integrated with other packaging materials, such as cardboard or plastic, to provide added strength and stability. Another benefit of steel coils in the packaging industry is their recyclability. Steel is one of the most recycled materials globally, and steel coils can be easily recycled and reused. This sustainability aspect makes steel coils an environmentally friendly choice for packaging, contributing to the reduction of waste and the conservation of resources. In summary, steel coils play a vital role in the packaging industry by offering strength, durability, corrosion resistance, versatility, and recyclability. Their use ensures the safe transport and storage of goods, providing a reliable and sustainable packaging solution for a wide range of industries.
