Description of RAL Scale Z65 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 RAL Scale Z30 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: What are the different coil packaging materials used for steel coils?
Different materials are used for packaging steel coils, each with its own unique properties and benefits. Some of the most commonly used materials are as follows: 1. Stretch film is a flexible material that tightly wraps around the coil, providing protection against dust, moisture, and scratches. 2. Steel strapping is a strong and durable option that ensures the coils remain tightly bound during transportation or storage, thanks to its high tensile strength and resistance to breakage. 3. Plastic strapping, on the other hand, is a lightweight and cost-effective alternative to steel strapping. It offers good shock absorption and is resistant to rust and corrosion, making it suitable for smaller or lighter steel coils. 4. Paperboard is an environmentally friendly packaging material that provides a protective layer against dust and minor impacts. It also allows for slight breathability to prevent moisture buildup. 5. Wooden crates are commonly used for large or heavy steel coils, as they offer sturdy support and protection during handling, transportation, or storage. 6. Corrugated cardboard is a versatile and lightweight material suitable for smaller steel coils. It provides cushioning and protection against minor impacts, and it is easily recyclable. The choice of packaging material for steel coils depends on factors such as coil size and weight, transportation requirements, and the desired level of protection. Each material has its own advantages and should be selected based on the specific needs of the steel coil packaging.
Q: How are steel coils used in the aerospace industry?
Steel coils are used in the aerospace industry for various applications including manufacturing aircraft components, structural supports, and engine parts. The coils are typically processed and shaped into specific forms such as sheets or plates, which are then used to construct critical components of aircrafts, ensuring strength, durability, and performance.

Q: How are steel coils used in the production of electrical conduits?
Several techniques are employed in the production of electrical conduits using steel coils. Firstly, the raw material for manufacturing electrical conduits is steel coils. These coils are composed of specially processed and formed high-quality steel, which is transformed into a continuous strip of considerable length. Once the steel coils are acquired, they are fed into a machine known as a slitter. This machine swiftly slices the coils into narrower strips of the desired width, which will function as the foundational material for the electrical conduits. The subsequent step involves shaping the steel strips into the desired conduit shape. This is accomplished by guiding the strips through a series of rollers and various shaping tools. Gradually, the steel strips take on the round or rectangular shape of the conduit as the rollers exert pressure and manipulate the strip until it reaches the desired form. After the shaping process, the ends of the steel strips are fused together to create a seamless conduit. This welding procedure ensures that the conduit possesses a structure devoid of any seams, a vital characteristic for its functionality and durability. Once the conduits have been shaped and welded, they undergo additional processing to enhance their properties. This may involve galvanizing, whereby a protective layer of zinc is applied to the conduits to shield them from corrosion. This additional layer significantly prolongs the lifespan of the conduits, rendering them suitable for a wide range of electrical applications. In summary, steel coils play a crucial role in the production of electrical conduits. These coils serve as the raw material that is shaped, welded, and further processed to create the final product. The utilization of steel coils ensures that the electrical conduits are robust, long-lasting, and capable of withstanding the rigorous demands of electrical installations.
Q: What are the dimensions of steel coils used in the transportation equipment industry?
The dimensions of steel coils used in the transportation equipment industry can vary depending on the specific application and manufacturer. However, commonly used dimensions range from 0.015 inches to 0.625 inches in thickness and from 24 inches to 60 inches in width. The outer diameter of these coils typically falls within the range of 48 inches to 72 inches.
Q: How are steel coils used in the production of household goods?
Steel coils are used in the production of household goods as they are a primary material for manufacturing various products. They are commonly used in appliances, such as refrigerators, stoves, and washing machines, as well as in furniture, shelving units, and even construction materials. The steel coils are typically shaped, cut, and formed into specific components or structures required for these household goods, ensuring durability and strength in the final products.
Q: How are steel coils used in the production of shipping vessels?
Steel coils serve as a crucial ingredient in the manufacturing of shipping vessels. Typically crafted from high-strength steel, these coils are ideal for fabricating the ships' hulls and other structural elements. In the shipbuilding process, the steel coils undergo an initial unrolling and cutting phase, where they are fashioned into specific sizes and shapes in accordance with the ship's design. These pre-cut pieces are then joined together through welding or bolting, forming the vessel's framework. This framework provides the necessary sturdiness and rigidity to withstand the unforgiving conditions of the sea. Additionally, steel coils are employed in the creation of decks, bulkheads, and various internal components of the shipping vessels. Molded into different sections, these coils are subsequently assembled and affixed to the ship's structure. The utilization of steel coils in these areas guarantees longevity and resistance to corrosion, which are vital for the overall durability and safety of the vessel. Moreover, steel coils find application in the production of ship propellers, rudders, and steering mechanisms. These components play an integral role in controlling the ship's movement and direction. The utilization of high-strength steel coils ensures the requisite robustness and dependability, facilitating smooth and efficient navigation. In summary, steel coils occupy a pivotal position in the manufacturing of shipping vessels. They provide strength, durability, and corrosion resistance, and are incorporated into various aspects of ship construction, ranging from the hull to the decks, bulkheads, and internal components. Absent steel coils, the production of shipping vessels would face significant challenges, resulting in ships lacking the necessary structural integrity to navigate the seas safely and efficiently.
Q: would you consider steel a flexible substance...i am debating this with my coworkers.Thanks,
Steel is a flexible material. It can be deformed and return to it's original shape up while the stress applied is still in the elastic range. How flexible depends on size, shape, and alloy. Some alloys are more flexible than others and a lot of this is controlled by carbon content.
Q: What is the average flatness tolerance for steel coils?
The average flatness tolerance for steel coils typically ranges between 0.25% and 0.5% of the coil's width.
Q: What are the common coil coating materials?
The common coil coating materials include polyester, polyvinylidene fluoride (PVDF), polyurethane, epoxy, and acrylic.
