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

- Q:How do steel coils contribute to the manufacturing of steel furniture?
- Steel coils play a crucial role in the manufacturing of steel furniture. These coils, which are made of high-quality steel, serve as the primary raw material for the production of various furniture items. Firstly, steel coils are used to create the framework and structure of steel furniture. These coils can be easily cut, shaped, and welded into various shapes and sizes, allowing manufacturers to create sturdy and durable furniture frames. The flexibility of steel coils enables the production of furniture with intricate designs and unique shapes, providing both functional and aesthetic value. Additionally, steel coils are also used in the production of springs for furniture such as sofas and chairs. The elasticity and strength of the steel coils make them ideal for creating comfortable and supportive seating options. These coils are carefully formed and integrated into the furniture, ensuring that the seating surface provides the necessary resilience and flexibility for a comfortable experience. Moreover, steel coils contribute to the overall durability and longevity of steel furniture. Steel is known for its high tensile strength and resistance to wear and tear, making it an excellent choice for furniture that is subjected to heavy use and weight load. The use of steel coils ensures that the furniture can withstand years of regular use without compromising its structural integrity. Furthermore, steel coils are often treated with various finishes and coatings to enhance their appearance and protect them from corrosion. These coatings can be applied to the coils before they are shaped into furniture components, ensuring that the final product maintains its aesthetic appeal and remains resistant to rust and other forms of damage. In conclusion, steel coils are an essential component in the manufacturing of steel furniture. They provide the necessary strength, flexibility, and durability required to create sturdy furniture frames, comfortable seating surfaces, and long-lasting products. Without steel coils, the production of steel furniture would not be possible, and the quality and performance of the final products would be compromised.
- Q:What are the different types of steel coil finishing processes?
- There are several different types of steel coil finishing processes that are used to enhance the appearance and properties of the steel coils. Some of the common types include: 1. Hot-dip galvanizing: This process involves immersing the steel coil in a bath of molten zinc, which creates a protective layer on the surface of the coil. This not only enhances the corrosion resistance of the steel but also provides a smooth and visually appealing finish. 2. Cold rolling: Cold rolling is a process in which the steel coil is passed through a series of rollers at room temperature to reduce its thickness and improve its surface finish. This process can impart a variety of finishes, ranging from a matte to a highly polished surface. 3. Electro-galvanizing: In this process, a thin layer of zinc is applied to the surface of the steel coil through an electrolytic deposition. Electro-galvanizing is commonly used for applications that require a thinner zinc coating and a more uniform finish. 4. Pickling and oiling: Pickling involves treating the steel coil with an acid solution to remove any scale or surface impurities, resulting in a clean and smooth surface. After pickling, the coil is usually coated with oil to prevent rusting during storage and transportation. 5. Powder coating: Powder coating is a popular finishing process that involves applying a dry powder to the steel coil and then curing it under heat to form a durable and attractive finish. This method allows for a wide range of colors and finishes to be applied to the steel. 6. Paint coating: Similar to powder coating, paint coating involves applying a liquid paint to the surface of the steel coil. This process can provide a decorative finish while also offering protection against corrosion and other environmental factors. These are just a few examples of the different types of steel coil finishing processes. The choice of the finishing method depends on the specific requirements of the application, such as the desired appearance, corrosion resistance, and durability.
