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.
4.Agriculture:barn; etc.
5.Others:vending machine; game machine; etc.

- Q: Having a greater amount than 2% carbon in steel causes steel to suddenly become brittle. Why is this?
- Carbon fiber has better tensile capability then steel meaning its better while pulled aside. Plus you could mould the fiber to make autos-or homes-out of carbon fiber.
- Q: How are steel coils used in the aerospace industry?
- Steel coils are used in the aerospace industry for various applications such as manufacturing aircraft components, including structural parts, engine components, and landing gear. These coils are often processed and formed into sheets, plates, or other desired shapes to meet the specific requirements of aerospace engineering. The high strength and durability of steel make it an ideal material for withstanding the demanding conditions and stresses experienced by aircraft during flight.
- Q: why does steel have a density range when other metals do not?
- Steel is not a pure element it is an alloy. Steel is primarily iron but it has many elements blended in that change it's density including carbon,silicon, nickel, chrome, etc. Aluminum and copper , magnesium and so forth can be the pure element or they can be alloys too. If they are alloys, then their densities vary also
- Q: Why buy recycled steel and from where to buy?
- Where you buy all your steel. The recycled and new steel are indistinguishable from each other. You won't recognize the one from the other. Same thing with glass. A certain percentage must be used glass, to enhance the quality of the total batch. Peace.
- Q: What is the minimum temperature that steel coils can withstand?
- The minimum temperature that steel coils can typically withstand is around -40 degrees Celsius.
- Q: How are steel coils used in the manufacturing of automotive frames?
- Steel coils are used in the manufacturing of automotive frames by being processed into flat sheets, which are then cut and formed into the desired shape and size to create the frame components. These components are then welded together to form the strong and durable structure of the automotive frame.
- Q: What are the different methods of forming steel coils?
- There are several methods used for forming steel coils, depending on the specific requirements and applications. These methods include hot rolling, cold rolling, and continuous casting. Hot rolling is the most common method used for forming steel coils. It involves heating the steel billet or ingot to high temperatures and then passing it between a series of rollers to reduce its thickness and shape it into a coil. This process is typically performed above the recrystallization temperature of the steel, which allows for better shaping and improved mechanical properties. Cold rolling, on the other hand, is a process that is performed at or near room temperature. It involves passing the steel through a series of rollers to reduce its thickness and shape it into a coil. Cold rolling is often employed to produce steel coils with precise dimensions and excellent surface finish. It can also increase the strength and hardness of the steel. Continuous casting is another method used for forming steel coils. It involves pouring molten steel into a continuous casting machine, where it is solidified into a strand. The strand is then continuously fed into a series of rollers, which shape it into a coil. Continuous casting offers several advantages, such as improved efficiency, reduced energy consumption, and better control over the steel's composition and quality. In addition to these primary methods, there are various secondary processes involved in forming steel coils. These include pickling, annealing, and coating. Pickling removes any rust or scale from the surface of the steel, ensuring a clean and smooth finish. Annealing involves heating the steel to a specific temperature and then slowly cooling it, which helps to improve its ductility and reduce internal stresses. Coating is often applied to steel coils to provide corrosion resistance or enhance its aesthetic appeal. In summary, the different methods of forming steel coils include hot rolling, cold rolling, and continuous casting. Each method offers unique advantages and is chosen based on the specific requirements of the steel product. Additionally, secondary processes such as pickling, annealing, and coating are often employed to further enhance the quality and performance of the steel coils.
- Q: How do steel coils impact the overall cost of production?
- The overall cost of production in various industries is greatly affected by steel coils. Initially, the expense of the steel coils themselves can be quite significant. The price of steel is influenced by several factors, including supply and demand, raw material costs, and market fluctuations. Any increase in the price of steel coils can directly impact the overall cost of production, as they are a major component in the manufacturing process. Furthermore, the operational costs of production are also influenced by steel coils. These coils are commonly used in different manufacturing processes, such as stamping, rolling, and forming, which require specialized machinery. The efficiency and effectiveness of these processes greatly depend on the durability, quality, and size of the steel coils. If the coils are of low quality or not suitable for the specific production requirements, it can result in increased downtime, machinery maintenance, and rework, all contributing to higher production costs. Additionally, the transportation costs associated with steel coils can impact the overall cost of production. Steel coils are typically heavy and bulky, requiring special handling and transportation arrangements. The logistics costs can be significantly influenced by factors such as the distance between the supplier and the production facility, as well as the chosen mode of transportation. Any rise in transportation expenses, such as fuel prices or shipping fees, can directly affect the overall cost of production. Lastly, the availability of steel coils can also impact production costs. During periods of high demand or limited supply, the price of steel coils may increase, resulting in higher production costs. Moreover, if there is a shortage of steel coils due to trade restrictions or disruptions in the supply chain, manufacturers may have to resort to alternative materials or sources, which could be more expensive or of lower quality. These factors can have a ripple effect on the overall cost of production. In conclusion, steel coils have a significant impact on the overall cost of production. Their cost, quality, transportation, and availability all influence the efficiency, effectiveness, and affordability of the manufacturing process. Therefore, manufacturers must carefully consider and manage these factors to optimize their production costs and maintain competitiveness in their respective industries.
- Q: What are the common coil processing methods?
