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 some of the greatest steel guitar songs in the history of country music. Western swing applies also.
- the answer would could be chum Emmons..he's performed with a number of the excellent artists in Nastyville!!! he's the guy who made all those Ray fee songs so bone chilling.
- Q: What are the different types of steel coil handling systems?
- There are several types of steel coil handling systems, including overhead crane systems, coil grab systems, coil transfer cars, and coil tilters. Each system is designed to efficiently and safely handle steel coils in different environments and applications.
- Q: Like 49ers. Pittsburgh have long history of steel industry?
- Yes. US Steel used to be in Pittsburgh, before Reagan let them move and destroyed Pittsburgh. Pittsburgh also used to have more than 1 million residents (in the early 80s) but now has less than 300K. The Pittsburgh Steelers symbol is the US Steel symbol, colored in.
- Q: Steel or stainless steel
- Steel often has impurities that can generate fumes, which cause a fever identical to smoke inhalation. You always need to be concerned about what you are breathing around hot metal.
- Q: Can steel coils be coated with tin?
- Yes, steel coils can be coated with tin.
- Q: How are steel coils inspected for width?
- Steel coils are inspected for width using various methods to ensure they meet the required specifications. One common method is to use a caliper gauge, also known as a micrometer, which measures the width of the coil by physically contacting its edges. The operator places the caliper gauge at various points along the width of the coil and records the measurements. This method allows for precise measurements and helps identify any inconsistencies or deviations from the desired width. Another method used for inspecting steel coil width is laser measurement. Laser sensors are positioned on both sides of the coil, and they emit a laser beam that scans across the width of the coil. The sensors detect the distance between the coil's edges and provide accurate width measurements. This non-contact method is highly efficient and can quickly inspect the width of the coil without any physical contact or potential damage. In addition to these methods, some advanced systems use computer vision technology for width inspection. Cameras and image processing software are employed to capture images of the coil's edges. The software analyzes these images and calculates the width based on the detected edges. This method allows for high-speed inspections and can detect any irregularities in the width of the coil. Overall, steel coils are inspected for width using a combination of physical gauges, laser sensors, and computer vision technology. These methods ensure that the coils meet the required width specifications and help maintain quality control in the steel manufacturing process.
- Q: What are the different methods of coil recoiling for steel coils?
- Steel coils can undergo coil recoiling using various methods, each with its own advantages and applications. Some commonly used methods include: 1. Slitting and rewinding: This method entails cutting the wide steel coil into narrower strips, which are then rewound into smaller coils. Circular blade slitting machines are typically employed for steel cutting, while the rewinding process ensures tight and uniform winding of the narrower strips. Industries like automotive, construction, and packaging widely employ this method. 2. Rewinding with tension control: This method involves unwinding and rewinding the steel coil using tension control systems. These systems maintain consistent tension throughout the recoiling process, resulting in uniform winding quality. This method proves beneficial when handling delicate or sensitive materials that require gentle treatment. 3. Recoiling with edge trimming: In situations where steel coil edges are damaged, uneven, or flawed, edge trimming can be combined with the recoiling process. Edge trimming machines remove defective sections, ensuring coils with smooth and even edges. 4. Recoiling with surface treatment: Steel coils often undergo surface treatment processes like oiling, coating, or galvanizing to enhance corrosion resistance or improve surface properties. Recoiling can be performed alongside these treatments, guaranteeing proper application and uniform coverage across the entire coil surface. 5. Recoiling with tension leveling: Tension leveling is a process that eliminates coil shape defects, such as coil set or crossbow, by applying tension during recoiling. This method ensures a flat and even coil shape, which is advantageous for subsequent processing and manufacturing operations. 6. Recoiling with precision slitting: Precision slitting is a specialized method used to achieve extremely narrow strip widths or tight tolerances in the steel coil. It involves precise control of slitting knives and winding tension to ensure accurate and consistent strip dimensions. Industries requiring high precision, such as electronics or precision engineering, commonly employ this method. In summary, the choice of coil recoiling method depends on factors such as desired coil dimensions, material characteristics, surface requirements, and the specific industry or application. Manufacturers often combine multiple methods to meet the diverse needs of their customers.
- Q: How are steel coils annealed for improved properties?
- Steel coils are annealed for improved properties by heating them to a specific temperature and then slowly cooling them down. This process, known as annealing, helps to relieve internal stresses in the steel, increase its ductility, and improve its machinability.
- Q: How are steel coils used in automotive manufacturing?
- Steel coils are used in automotive manufacturing to produce various components and parts such as body panels, chassis, doors, and other structural parts. The coils are processed through different techniques like cutting, stamping, and welding to shape them into the desired form. This allows for the production of strong and durable automotive parts, ensuring the safety and reliability of vehicles.
