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 industries that consume the most steel?
- Costuuction and auto are most likely the top two.
- Q: What are the common coil width tolerances?
- The common coil width tolerances vary depending on the industry and specific application. However, typical coil width tolerances range from +/- 0.005 to 0.030 inches.
- Q: Can steel coils be coated with anti-microbial materials?
- Yes, steel coils can be coated with anti-microbial materials. These coatings can help inhibit the growth of bacteria, fungi, and other microorganisms, making the steel coils more resistant to contamination and reducing the risk of transmission of harmful pathogens.
- 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 coated for corrosion resistance?
- Steel coils are typically coated for corrosion resistance using various methods such as hot-dip galvanizing, electroplating, or applying a protective layer of paint or powder coating.
- Q: which is the most tough and durable steel type ??
- C'mon. Really? That's your question? How about some actual details like the application, is it going to be formed into a shape, do you need to weld it, what type of environment like corrosion and temperature is it going to be subject to? There are roughly 2,000 grades of steel and a couple hundred grades of stainless steel. Steels can be soft or they can be exceptionally hard. We need more info please.
- Q: Why people prefer prefabricated buildings these days? Recently my friend has told me that he is going to owe a steel house so I was just thinking are these steel structures really durable and cheaper than concrete structures?
- Hi., I think steel is the best option for the building ..
- Q: What are the common methods of handling steel coils during production?
- The common methods of handling steel coils during production include using overhead cranes, forklifts, and coil tongs. These tools are utilized to lift, transport, and position the coils within the production facility. Additionally, coil cars and transfer systems are often used to move the coils between different stages of the production process. It is crucial to handle the steel coils with care to prevent damage and ensure efficiency in the production line.
- Q: What are the different coil surface finishes?
- Some of the different coil surface finishes include plain, polished, brushed, embossed, and coated.
