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:ive made lots of knives but they are dark and not shiny. how do i polish a knife and make it shiny
- Look for buffing compound at the hardware store. Home depot lowe's od even Wal-mart/ There is a compound for steel and for iron. I t will not make iron real shinny but it will make it look good. This stuff is to be used with a buffing wheel but I have used it on rags and it work great.
- Q:What are the different coating options for steel coils?
- There are several coating options available for steel coils, each serving different purposes and providing unique benefits. Some of the commonly used coating options for steel coils include: 1. Galvanized Coating: This coating involves immersing the steel coils in a bath of molten zinc, creating a layer of zinc on the surface. Galvanized coating provides excellent corrosion resistance and protects the steel from rusting. It is commonly used in applications where the steel coils are exposed to harsh environments or moisture. 2. Galvannealed Coating: This coating is a combination of galvanizing and annealing processes. The steel coils are first galvanized and then annealed to create a layer of zinc-iron alloy on the surface. Galvannealed coating offers enhanced paintability and weldability while providing good corrosion resistance. 3. Aluminum-Zinc Alloy Coating: Also known as Galvalume, this coating consists of an aluminum-zinc alloy applied to the steel coils. It provides excellent corrosion resistance and heat reflectivity, making it suitable for various applications, including roofing, siding, and automotive parts. 4. Organic Coatings: These coatings are typically applied as a top layer over a base coat of galvanized or galvannealed coating. Organic coatings can be in the form of paints, lacquers, or powder coatings. They provide additional protection against corrosion, UV rays, and abrasion, while also enhancing the aesthetics of the steel coils. 5. Chromate Conversion Coating: This coating is primarily used as a pre-treatment before applying organic coatings. It helps improve adhesion between the steel surface and the organic coating, ensuring better corrosion resistance. The choice of coating depends on various factors such as the intended application, environmental conditions, desired appearance, and budget. Manufacturers and end-users should carefully consider these factors to select the most suitable coating option for their specific requirements.
- Q:Which of the two are better for exhaust manifolds, im guessing the stainless steel right?
- stainless
- Q:What are the dimensions of steel coils?
- The dimensions of steel coils vary depending on factors such as the specific type of steel, the intended use, and industry standards. Generally, steel coils can range in width from a few inches to several feet, with thicknesses typically ranging from a fraction of an inch to several millimeters. The inner diameter of a steel coil can also vary, with common sizes being 20 inches and 24 inches. Ultimately, the dimensions of steel coils are determined by the specific needs and requirements of the end user.
- Q:This needs to be in a percentage by mass. Could you please also reference where this info has come from. Thanks.
- Graphite is a lot lighter and will allow you to generate more swing speed and probably greater distance. I hit my graphite clubs about one club longer than my steel shafts. But, my steel shafts are far more accurate. I find I hit a lot more greens in regulation using my steel shafted irons than I do with my graphites. Since accuracy is far more important than distance for most people, I choose the steel shafted irons most of the time. You will NEVER see a professional or a low handicapper using graphite irons for this reason.
- Q:What are the surface treatments for steel coils?
- Some common surface treatments for steel coils include galvanizing, painting, and coating. These treatments are applied to protect the steel from corrosion, improve its appearance, and enhance its durability.
- Q:How are steel coils used in the production of electrical resistors?
- Steel coils are used in the production of electrical resistors as they provide a conductive material that can withstand high temperatures. The steel coil is wound into a spiral shape to increase the length of the wire, which in turn increases the resistance. This allows the resistor to regulate the flow of electric current in a circuit, providing the desired level of resistance.

- Q:What are the different methods of coil flattening for steel coils?
- There are several methods of coil flattening for steel coils, each with its own advantages and limitations. Some of the most commonly used methods include: 1. Roller leveling: This method involves passing the steel coil through a series of rollers that apply pressure to flatten the coil. The rollers can be adjustable to achieve the desired level of flatness. Roller leveling is a versatile method that can handle a wide range of coil sizes and thicknesses. 2. Precision leveling: This method utilizes a more sophisticated leveling machine that applies pressure on specific areas of the coil to eliminate any waviness or defects. Precision leveling is often used for high-quality steel coils that require extremely flat surfaces. 3. Stretch leveling: Also known as tension leveling, this method involves stretching the steel coil beyond its yield point, causing it to permanently deform and flatten. Stretch leveling is commonly used for thinner gauge coils and can effectively remove coil set and crossbow defects. 4. Temper rolling: This method involves subjecting the steel coil to a controlled low-temperature heat treatment followed by cold rolling. The combination of heat and cold rolling helps to relieve internal stresses and improve flatness. Temper rolling is particularly suitable for coils that require enhanced surface quality. 5. Laser flattening: This advanced method utilizes laser technology to selectively heat and flatten specific areas of the coil. Laser flattening is highly precise and can correct localized defects or unevenness, but it is typically used for smaller coils due to its higher cost. It is important to note that the selection of the most appropriate method for coil flattening depends on various factors, including the desired flatness requirements, coil dimensions, material properties, and production budget.
- Q:How are steel coils tested for tensile strength?
- Steel coils are typically tested for tensile strength through a process called tension testing, where a sample of the coil is pulled until it breaks. This test measures the maximum amount of force the steel can withstand without breaking, helping to determine its tensile strength.
