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.

- Q: What are the different types of steel coil coatings for corrosion resistance?
- There are several types of steel coil coatings available for corrosion resistance, including galvanized coatings, galvannealed coatings, and organic coatings.
- Q: How are steel coils used in the production of storage containers?
- In the production of storage containers, steel coils play a vital role. These coils, manufactured from high-quality steel, are crucial for constructing the walls, floors, and roofs of the containers. To begin the process, the steel coil is uncoiled and passed through a series of machines that cut and shape it into the desired dimensions. Then, the steel is transformed into panels, which are either welded or riveted together to form the container's structure. The strength, durability, and resistance to corrosion make steel coils an excellent material for storage containers. They provide a robust framework that can endure heavy loads and harsh environmental conditions. Moreover, the coils can be easily molded and customized to meet specific size and shape requirements. Once the structure of the container is complete, it is typically coated with a protective layer of paint or other coatings to further enhance its durability and resistance against weather elements. This ensures that the container remains unaffected by moisture, UV rays, and other external factors that could cause deterioration. All in all, steel coils are of utmost importance in the production of storage containers as they offer the necessary strength and durability required to safely store and transport a wide array of goods and materials.
- Q: How do steel coils contribute to the automotive industry?
- Steel coils are a crucial component in the automotive industry as they are used to manufacture various parts of vehicles, including the body frame, doors, hoods, and chassis. The high strength and durability of steel coils make them ideal for enhancing the safety, structural integrity, and overall performance of automobiles. Additionally, steel coils are cost-effective, readily available, and can be easily formed into different shapes and sizes, making them an essential material in the production of cars and trucks.
- Q: I want to know the special characters or the advantages of the corton steel. In what cases it is recommended to use?Thank you.
- *It is Corten steel.Grade A B. *Weathering steel, best-known under the trademark COR-TEN steel, is a group of steel alloys which were developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. United States Steel Corporation (USS) holds the registered trademark on the name COR-TEN. Although USS sold its discrete plate business to International Steel Group (now Arcelor-Mittal) in 2003, it still sells COR-TEN branded material in strip-mill plate and sheet forms. In some areas it may be known without the hyphen as Corten steel. The original COR-TEN received the standard designation A242 (COR-TEN A) from the ASTM International standards group. Newer ASTM grades are A588 (COR-TEN B) and A606 for thin sheet. All alloys are in common production and use. It is a weather-resistant steel which is used in containers and hot flue gas line. The American Corten A Steel has a composition of C, 0.12; Si, 0.5; Cu, 0.5; Cr, 0.8; P, 0.1 and Mn, 0.5%. Although the tensile strength is less than 494 MPa the yield is in the region of 371 MPa. The combination of copper and phosphorus also increases the resistance to atmospheric corrosion which is important when thinner plates are used. The original steel A suffers a decrease in yield strength and notch ductility in thickness over 25 mm, to overcome which Corten B was developed-C 0.14; P 0.04; Mn 1.1; Cr 0.5; Cu 0.4; V 0.1; Bol Al 0.02. *COR-TEN A applies to plates up to 12.5mm in thickness, COR-TEN B applies to plates up to 50mm in thickness. *It has been used in bridge and other large structural applications such as the New River Gorge Bridge, the newer span of the Newburgh-Beacon Bridge, and the creation of the Australian Centre for Contemporary Art (ACCA). It is very widely used in marine transportation, in the construction of shipping containers.
- Q: How are steel coils used in the manufacturing of automotive fenders?
- Steel coils are used in the manufacturing of automotive fenders by being shaped and formed into the desired fender design. The coils are cut and stamped into specific shapes, then undergo a series of bending, welding, and finishing processes to create the final fender product. The strength and durability of steel make it an ideal material for fenders, providing protection to the vehicle's wheels and body in case of collisions or impacts.
- Q: I need to say how a bottle opener is made, would it be made from steel and can this be coloured? How?
- Steel can be plated(Chrome),Blackened(Black Oxide),Powder coated(color of your choose).All of this is done to prevent rust.All of these aforementioned processes can be worn off through being used.I suggest polished Stainless steel.
- Q: How are steel coils used in the production of rail tracks?
- Steel coils are used in the production of rail tracks as they are a primary raw material for manufacturing the rails. These coils are first processed to form the desired shape and dimensions of the rail tracks, which are then cut, welded, and shaped to create the individual rail sections. The steel coils provide the strength, durability, and flexibility necessary for the tracks to withstand heavy loads, extreme weather conditions, and constant use.
- Q: What are the common methods of painting or coating steel coils?
- Coil coating is a commonly used technique for painting or coating steel coils. It involves cleaning and pre-treating the coils to remove contaminants and enhance adhesion. Next, a primer or base coat is applied to establish a solid foundation. This primer safeguards the steel against corrosion and enhances the overall durability of the coating. Once the primer is applied, the steel coils undergo a series of rollers to apply the topcoat. The topcoat can consist of various materials such as polyester, polyurethane, or fluoropolymer, depending on the desired properties of the final coating. These topcoats provide the desired color, gloss, and protection against weathering, chemical exposure, and UV radiation. Electrostatic spraying is another popular method for painting or coating steel coils. It involves atomizing the paint or coating material into fine droplets and charging them with electricity. The grounded steel coils attract these charged droplets, resulting in a controlled and even application of the paint or coating material. Powder coating is yet another technique utilized for painting or coating steel coils. It involves electrostatically charging a dry powder and spraying it onto the steel coils. The charged powder adheres to the steel surface due to electrostatic attraction. The coated steel coils are then heated, causing the powder to melt and form a continuous film, resulting in a durable and resistant coating. In conclusion, these methods provide a wide range of options in terms of color, finish, and performance characteristics for painting or coating steel coils. The choice of method depends on factors such as desired appearance, level of protection required, and specific application requirements.
- Q: Ok, so I'm obsessed with learning how to play the guitar (I preffer acoustic)... I'm a teenage girl that wants to play rock/pop/folk music... I want to learn first how to strum... then eventually how to pick...so what type of string is better? nylon or steel?
- You should start with a steel string guitar. Guitars with nylon strings are classical guitars and are used primarily for classical music, which is why you so rarely see a pop singer playing one. Don't worry about your fingers; they will hurt a little for the first week or two whether you have steel or nylon strings and then that will go away forever. You might want to consider using light gauge steel strings (or even extra light gauge) at first to make fretting easier. Good luck.
- Q: How do steel coils perform in high-temperature applications?
- Steel coils perform well in high-temperature applications due to their excellent heat resistance and structural stability. The high melting point of steel allows it to maintain its strength and shape even at elevated temperatures, making it suitable for various industries such as automotive, construction, and manufacturing. Additionally, steel coils can withstand thermal expansion and contraction without warping or deforming, ensuring reliable performance and durability in extreme heat conditions.
