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: Can steel coils be coated with anti-static materials?
- Yes, steel coils can be coated with anti-static materials to help reduce or eliminate static electricity buildup and discharge. Anti-static coatings are commonly applied to various surfaces, including metals, to prevent damage to sensitive electronic components, improve safety, and enhance overall product performance.
- Q: how is stainless steel made? what are the things used in making it?
- There are 3 basic stainless steels. The Martinsitic, the ferritic, and the Austinistic. The spelling may be wrong on all of them. (Got out of school in 1966 with my metallurgy in 1965. The Ferritic is magnetic and has some resistance to corrosion but the Martinsitic is much more resistant to corrosion. The Austinitic stainless is very resistant to corrosion. The differences are the amount of Chrome and Nickel in the batches. The Austinitic has an 18/8 ratio of Chromium and Nickel with the rest Iron and minor ingredients. The carbon content is very important and these steels are often made in small batches with close monitoring of composition and carbon content. Scrap metals are frequently used with the chrome and nickel being added as carefully selected scrap or even fresh crude stocks. Electric melting is frequent to avoid contamination.
- Q: How are steel coils loaded onto trucks or containers?
- Steel coils are typically loaded onto trucks or containers using specialized equipment such as cranes, forklifts, or coil trailers. The coils are lifted and secured onto the truck or container using straps, chains, or clamps to ensure safe transportation.
- Q: How are steel coils processed for different finishes?
- Steel coils are processed for different finishes through various techniques such as hot rolling, cold rolling, pickling, and coating. Hot rolling involves heating the steel coils and passing them through rollers to achieve desired thickness and shape. Cold rolling further enhances the surface finish by reducing thickness and increasing strength. Pickling involves removing impurities and scale from the surface of the steel coils using acid solutions. Finally, coating techniques like galvanization or painting are used to provide protective and decorative finishes to the steel coils.
- Q: What are the different methods of cutting edge trimming for steel coils?
- There are several methods of cutting edge trimming for steel coils, including shearing, slitting, laser cutting, and plasma cutting. Shearing involves using a sharp blade to cut through the coil's edge, while slitting involves using multiple circular blades to make longitudinal cuts. Laser cutting uses a high-powered laser beam to melt and vaporize the material, producing a precise and clean cut. Plasma cutting involves using a high-temperature plasma arc to melt and cut through the steel. Each method has its advantages and is chosen based on factors such as the required precision, speed, and cost-effectiveness.
- Q: What is steel made of and what is its molecular weight? It's for a project in chemistry class so if you have a website link as well, that would be great!
- Steel is an alloy consisting mostly of iron with a little Carbon thrown in. Steel is not a molecule, therefore, it does not have a molecular weight. Steel contains atoms of iron and carbon in a crystal lattice, along with various other alloying elements such as manganese, chromium, vanadium, and tungsten.
- Q: What are the different types of steel coil finishing processes?
- Enhancing the appearance and properties of steel coils involves employing various steel coil finishing processes. Among the commonly used processes are: 1. Hot-dip galvanizing: Immersing the steel coil in molten zinc forms a protective layer on its surface, enhancing corrosion resistance and providing a visually pleasing finish. 2. Cold rolling: Passing the steel coil through rollers at room temperature reduces thickness and improves surface finish. This process can yield finishes ranging from matte to highly polished. 3. Electro-galvanizing: A thin layer of zinc is electrolytically deposited onto the steel coil's surface. This method is suitable for applications requiring a thinner zinc coating and a more uniform finish. 4. Pickling and oiling: Treating the steel coil with an acid solution removes scale and impurities, resulting in a clean and smooth surface. Coating the coil with oil prevents rust during storage and transportation. 5. Powder coating: Dry powder is applied to the steel coil and cured under heat to form a durable and attractive finish. This method allows for a wide range of colors and finishes. 6. Paint coating: Similar to powder coating, liquid paint is applied to the steel coil's surface. This process offers decorative finishes and protection against corrosion and environmental factors. These examples represent only a few of the available steel coil finishing processes. The choice of method depends on specific application requirements, including desired appearance, corrosion resistance, and durability.
- Q: How do steel coils compare to other materials?
- There are multiple advantages to using steel coils instead of other materials. Firstly, steel is renowned for its strength and durability, which makes steel coils highly resistant to wear and tear. This quality allows them to be used in a wide range of applications. Additionally, steel coils have excellent heat resistance, making them ideal for high-temperature environments.
