Description of Prepainted Rolled steel Coil for Construction Roofing
Prepainted Rolled steel Coil 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 Rolled steel Coil for Construction Roofing
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 Rolled steel Coil for Construction Roofing
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 loaded onto a truck?
- Loading steel coils onto a truck is typically accomplished by combining machinery and manual labor. To ensure safe and efficient loading, several steps are involved. To begin, the truck must be adequately prepared. This entails cleaning the truck's bed and removing any debris or obstacles that could hinder the loading process. Additionally, protective materials like rubber mats may be placed on the truck's bed to safeguard both the coils and the truck. Next, a forklift or crane is utilized to lift and position the steel coils onto the truck. The operator must handle the coils with care, ensuring they are balanced and securely fastened to prevent movement during transportation. Adhering to proper lifting techniques and safety protocols is critical to avoid accidents or coil damage. After the coils are positioned on the truck, various methods can be employed to secure them. This may involve using straps, chains, or other restraints to hold the coils in place and prevent shifting or falling while in transit. The restraints must be appropriately tightened and inspected to withstand the weight and movement of the coils. It is worth noting that the loading process may vary based on the size and weight of the steel coils, as well as the available equipment. Some trucks may feature specialized loading systems specifically designed for steel coils, streamlining the process and enhancing safety. In summary, loading steel coils onto a truck necessitates meticulous planning, skilled operators, and suitable equipment. Adhering to proper procedures and safety measures is vital to ensure successful coil transportation and prevent accidents or damage.
- Q: How are steel coils used in the production of roofing and siding?
- Steel coils are an essential component in the production of roofing and siding materials. These coils, made from high-quality steel, undergo various processes to transform them into the final products used for roofing and siding purposes. Firstly, the steel coils are uncoiled and flattened to obtain a flat sheet of steel. This sheet is then cleaned to remove any impurities or contaminants. The cleaning process involves treating the surface of the steel with chemicals and rinsing it thoroughly to ensure a clean and smooth surface. Next, the steel sheet is coated with a protective layer to enhance its durability and resistance to corrosion. This coating can be done through various methods such as hot-dip galvanizing, electro-galvanizing, or applying a layer of metallic or organic coating. The specific coating method depends on the desired properties and aesthetic requirements of the roofing or siding material. After the coating process, the steel sheet is formed into the desired shape and profile. For roofing applications, the steel sheet is typically corrugated or formed into interlocking panels. This allows for easy installation and ensures a secure and weatherproof roofing system. Similarly, for siding applications, the steel sheet can be formed into different profiles such as horizontal or vertical panels, shingles, or shakes. Once the steel sheet is formed, it may undergo additional treatments to enhance its performance. This can include applying a protective layer of paint or other finishes to improve its appearance and resistance to fading, chipping, or scratching. The steel coils can also be embossed or stamped with patterns or textures to provide aesthetic appeal. Overall, steel coils play a crucial role in the production of roofing and siding materials. They provide strength, durability, and weather resistance, making them an ideal choice for protecting buildings from the elements. Additionally, steel coils offer versatility in terms of shape, profile, and finish, allowing for a wide range of design options for roofing and siding applications.
