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.

- Q: How are steel coils used in the manufacturing of storage systems?
- Steel coils are an essential component in the manufacturing of storage systems due to their durability, strength, and versatility. These coils are typically made from high-quality steel and are created by rolling the steel into a coil shape. In the manufacturing process of storage systems, steel coils serve various purposes. One of the primary uses of these coils is for the construction of shelves, racks, and frames. These components provide the structural support necessary to hold and organize items within the storage system. The strength of the steel coils ensures that the storage system can withstand heavy loads and remain stable over time. Additionally, steel coils are also used in the production of storage system accessories such as brackets, hooks, and dividers. These accessories provide additional functionality and customization options for the storage system, allowing users to optimize their storage space based on their specific needs. Moreover, steel coils are often used as the material for doors and panels in storage systems. The coils are molded and shaped to create sturdy and secure doors that provide easy access to the stored items while maintaining the overall integrity of the system. These doors can be designed with various locking mechanisms to enhance security and prevent unauthorized access. Furthermore, steel coils are crucial in the manufacturing of mobile storage systems. These systems, such as mobile shelving units or compactors, are designed to maximize storage capacity in limited space. The flexibility and versatility of steel coils allow for the creation of movable components that can be easily adjusted and reconfigured to accommodate changing storage requirements. Overall, steel coils play a vital role in the manufacturing of storage systems by providing the necessary strength, durability, and versatility required for these structures. Whether it is for shelves, accessories, doors, or mobile systems, steel coils ensure that storage systems are reliable, secure, and efficient in organizing and storing various items.
- Q: what exactly does it mean when some sword makers refer to finding the truth of steel. I have heard that many have tried to find the truth but i dont really understand what there is to find.
- I am unsure of what the Truth of Steel is, but here is the Riddle of Steel (from Conan) Thulsa Doom: Yes! You know what it is, don't you boy? Shall I tell you? It's the least I can do. Steel isn't strong, boy, flesh is stronger! Look around you. There, on the rocks; a beautiful girl. Come to me, my child... Thulsa Doom: [coaxes the girl to jump to her death] Thulsa Doom: That is strength, boy! That is power! What is steel compared to the hand that wields it? Look at the strength in your body, the desire in your heart, I gave you this! Such a waste. Contemplate this on the tree of woe. Crucify him!
- Q: Can steel coils be transported by air?
- Yes, steel coils can be transported by air. However, it is important to note that the size and weight of the coils may limit the type of aircraft that can be used for transportation. Additionally, special equipment and packaging may be required to ensure the safe and secure transport of the coils.

- Q: What is the process of galvanizing steel coils?
- Enhancing the durability and protecting steel coils from corrosion involves a series of steps in the galvanization process. To begin, the steel coils undergo a thorough cleaning to eliminate any dirt, oil, or impurities on the surface. This is achieved through an acid pickling process, where the coils are immersed in a diluted acid solution or treated with a chemical cleaner. The aim is to ensure the surface of the coils is free from contaminants, allowing for better adhesion of the zinc coating. Following the cleaning process, the coils are rinsed to remove any remaining acid or cleaner, preventing adverse reactions in the next stage. The subsequent step involves the actual galvanization, where the cleaned coils are submerged in a bath of molten zinc. To guarantee an even coating, the coils are carefully passed through the zinc bath using rollers or other mechanisms. The zinc bath is maintained at a specific temperature, typically around 450°C (842°F), enabling the molten zinc to bond with the steel surface. Upon withdrawal from the zinc bath, excess zinc is eliminated by passing the coils through air knives or by centrifugal spinning. This ensures control over the thickness of the zinc coating, resulting in a uniform appearance. Once the galvanization process is complete, the steel coils are gradually cooled to room temperature. This facilitates the solidification and firm bonding of the zinc coating with the steel surface, creating a protective barrier against corrosion. The final step involves inspection and quality control. The galvanized steel coils are carefully examined for any defects, such as uneven coating or areas with insufficient zinc coverage. This inspection is typically conducted visually or using specialized equipment capable of detecting anomalies. Additionally, the coating thickness is measured to ensure it meets the required specifications. In conclusion, the galvanization process for steel coils is designed to enhance their longevity and shield them from rust and corrosion. By applying a layer of zinc coating to the steel surface, the coils become more resistant to environmental factors, making them suitable for a wide range of applications across various industries.
- Q: What are the different surface treatments available for steel coils?
- There are various surface treatments available for steel coils, including hot-dip galvanizing, electro-galvanizing, zinc plating, painting, powder coating, and organic coating.
- Q: What are the different types of steel coils?
- There are several different types of steel coils, including hot rolled coils, cold rolled coils, galvanized coils, and stainless steel coils.
- Q: How are steel coils processed into finished products?
- Steel coils are processed into finished products through a series of steps that typically include uncoiling, leveling, cutting, and shaping. After uncoiling, the steel coils are passed through a leveling machine to remove any unevenness. Then, they are cut into specific sizes and shapes using different cutting techniques such as shearing or slitting. Finally, the cut steel pieces are shaped through various processes like bending, welding, and machining to produce the desired finished products.
- Q: Are steel coils used in automotive manufacturing?
- Yes, steel coils are commonly used in automotive manufacturing. They are used to make various components of vehicles such as body panels, chassis, and suspension systems. The high strength and durability of steel make it an ideal material for ensuring the safety and performance of automobiles.
