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 common coil transportation methods?
- The common coil transportation methods include trucking, railway transportation, and shipping.
- Q: What are the dimensions of steel coils used in the agricultural equipment industry?
- The dimensions of steel coils utilized in the agricultural equipment sector differ based on the precise application and equipment requirements. Nevertheless, there are several prevalent dimensions for steel coils employed in this industry, spanning from 0.5mm to 6mm in thickness and 600mm to 2000mm in width. The length of the coils can be tailored to suit the particular equipment demands. Furthermore, the weight of the coils can fluctuate, generally ranging from a few hundred kilograms to multiple tons. It is crucial to acknowledge that these dimensions are not set in stone and may vary depending on the manufacturer and the specific agricultural equipment being manufactured.
- Q: Can steel coils be stored vertically?
- Yes, steel coils can be stored vertically.
- Q: which pokemon has the most steel pokemon???
- Transformers.
- Q: How is the critical temperature of structural steel affected by fireproofing? What temperatures can fireproofed structural steel withstand?
- This would depend upon the method of fireproofing. Steel used to be insulated with an asbestos coating. Of course the steel under the insulation had the same critical temperature as the uncoated steel but was protected from external heat by the insulation. More commonly it would be an alloy and there are so many that one could not guess except to say it should be higher than the original.
- Q: What are the different thickness tolerances for steel coils?
- The different thickness tolerances for steel coils can vary depending on the specific grade and type of steel being used, as well as the industry standards and customer requirements. However, common thickness tolerances for steel coils typically range from +/- 0.005 inches to +/- 0.020 inches, with tighter tolerances available for certain applications.
- Q: What is the role of steel coils in the manufacturing of bridges?
- Steel coils play a crucial role in the manufacturing of bridges as they are used as the primary material for constructing the structural components of the bridge, such as beams, columns, and girders. These coils are manufactured by rolling steel into flat strips, which are then wound into large coils. The high strength and durability of steel make it an ideal choice for bridge construction, as it can withstand heavy loads, extreme weather conditions, and provide long-lasting support. The coils are processed further to fabricate the required bridge components, ensuring the structural integrity and stability of the bridge.
- Q: Can you weld copper or brass to steel?
- GTAW,Weld Copper to steel, RN-60. Silver Braze Copper to Steel, Grade 4 Silver.
- Q: How are steel coils tested for tensile strength?
- Steel coils are typically tested for tensile strength using a method called tensile testing. This involves subjecting a sample of the steel coil to a controlled pulling force until it breaks. The force required to break the sample is then measured, providing an accurate measure of the steel's tensile strength.
- Q: What are the different methods of coating steel coils?
- There exist numerous techniques for coating steel coils, each offering distinct advantages and applications. A few of the most prevalent methods comprise: 1. Hot-dip galvanizing: The process entails immersing the steel coils in molten zinc. This results in a protective layer forming on the steel's surface, thereby providing exceptional corrosion resistance and durability. 2. Electro-galvanizing: This method applies a layer of zinc to the steel coils using an electroplating procedure. It delivers a similar level of corrosion resistance as hot-dip galvanizing but with a thinner coating. 3. Electro-coating (E-coating): Also known as electrodeposition, this approach involves submerging the steel coils in a bath containing electrically charged particles of paint or resin. By applying an electrical current, these particles adhere to the steel's surface. E-coating provides outstanding corrosion protection and is often used as a primer before applying additional coatings. 4. Powder coating: Steel coils can undergo a dry powder paint application that utilizes electrostatic charging, followed by baking the coating onto the surface. This technique provides a wide array of colors, finishes, and textures, thus offering both aesthetic appeal and corrosion resistance. 5. Organic coatings: These coatings, such as paints or lacquers, are applied to the steel coils using various methods like spray, roller, or dip coating. Organic coatings offer protection against corrosion while also allowing for customizable colors and finishes. Each method of coating steel coils possesses its own set of advantages and is chosen based on the desired level of corrosion resistance, appearance, and specific end-use requirements.
