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: What are the dimensions of a steel coil?
- The dimensions of a steel coil can vary depending on its intended use and manufacturer. However, typical dimensions include a width ranging from 600mm to 2,200mm, a diameter of 600mm to 2,000mm, and a weight ranging from a few hundred kilograms to several metric tons.
- Q: What is the maximum width of steel coils?
- The maximum width of steel coils is subject to variation, influenced by factors like steel type, manufacturing capabilities, and intended usage. Nevertheless, in most cases, steel coils tend to have a maximum width of approximately 2,200 millimeters or 86.6 inches. This width is widely employed in the steel industry for coils of standard sizes. It is worth mentioning that wider widths may be achievable through specialized steel coils or custom manufacturing methods, albeit less frequently and possibly necessitating particular equipment or processes.
- Q: How are steel coils used in the oil and gas industry?
- Steel coils are commonly used in the oil and gas industry for various purposes such as manufacturing pipelines, storage tanks, and offshore platforms. These coils are formed into cylindrical shapes and serve as the main structural component for these applications, providing strength, durability, and resistance to extreme conditions. Additionally, steel coils are used in the production of equipment like heat exchangers, compressors, and drilling machinery, which are essential for the extraction, processing, and transportation of oil and gas.
- Q: How are steel coils used in the manufacturing of HVAC ductwork?
- Steel coils are used in the manufacturing of HVAC ductwork as they provide the necessary strength and durability required for the ductwork. These coils are typically processed through a roll-forming machine, which shapes them into the required ductwork profile. The steel coils are then cut to the desired length, welded or joined together, and finally, coated to prevent corrosion and improve the overall performance of the ductwork.
- Q: What are the dimensions of steel coils used in the electrical equipment industry?
- The dimensions of steel coils utilized in the electrical equipment industry may differ based on the particular application and requirements of the equipment being produced. However, there are certain dimensions that are commonly employed in this industry. Typically, the width of steel coils employed in the manufacturing of electrical equipment ranges from 0.5 inches to 72 inches (1.27 cm to 182.88 cm). The thickness of these coils can vary from extremely thin, measuring 0.005 inches (0.0127 cm), to considerably thick, measuring 0.25 inches (0.635 cm). The length of steel coils employed in the electrical equipment industry can also vary, but it is often determined by the production process and the specific equipment being manufactured. Coils can range in length from a few feet to several hundred feet. Moreover, the weight of steel coils can differ based on their dimensions and the type of steel being utilized. For example, a common weight range for steel coils employed in the electrical equipment industry falls between 5,000 pounds (2,268 kg) and 50,000 pounds (22,680 kg). It should be noted that these dimensions are not fixed and can vary depending on the specific requirements of the electrical equipment industry. Manufacturers may have their own distinct specifications and requirements for the steel coils they utilize in their products.
- Q: Two different shaving razors I'm looking to buy have different specs. in terms of the metals used for the blade; one being 1045 surgical stainless steel, the other 440 stainless (not sure if its A B or C, but probably 440A or 440B because it's not specified). So which one is better for the intended use as a shaving razor?
- 1045 stainless is better
- Q: How hot does steel have to get before it will melt?
- Type your query into Yahoo! Search or other search engines to get the answer: It depends, since steel usually has different metals added for various properties (strength, corrosive resistance, etc.)
- Q: How are steel coils used in the production of automotive body panels?
- Steel coils are used in the production of automotive body panels by being processed and formed into the desired shape and size. The coils are typically unwound and fed through a series of machines that stamp, press, or roll the steel into the required panel shape. This process allows for efficient mass production of body panels, ensuring strength, durability, and precision in the final product.
- Q: I need to know a name of any site which provides information on Steel structures??
- steel structure- TC bolt to connect,SG shear wrench
- Q: Can steel coils be used in the production of automotive parts?
- Indeed, the utilization of steel coils is possible in the manufacturing of automotive parts. Various automotive components like body panels, frames, chassis, suspension parts, and engine parts frequently incorporate steel coils within their production process. To achieve the desired shape of these automotive parts, the steel coils typically undergo a range of techniques including cutting, stamping, bending, and welding. The strength, durability, and corrosion resistance of steel make it a favored material for automotive parts. Additionally, steel coils are accessible in different grades and thicknesses, enabling manufacturers to customize the material properties to fulfill specific requirements for diverse automotive applications. Collectively, steel coils play a crucial role in the fabrication of automotive parts, thereby contributing significantly to the performance, safety, and durability of vehicles.
