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: How are steel coils used in the production of food processing machinery?
- Steel coils are used in the production of food processing machinery as they are commonly used to create the structural frames and components of the machinery. Additionally, steel coils are often used to manufacture cutting blades, conveyor belts, and various other parts that require strength and durability in the food processing industry.
- Q: What are the different types of packaging for steel coils?
- Steel coils can be packaged in various ways to meet the specific needs and preferences of manufacturers and distributors. Here are some commonly used packaging options: 1. Wooden Crates: To ensure safe transportation and handling, steel coils can be packed in robust wooden crates. These crates, made of durable wood materials like plywood or solid wood, provide excellent protection by securely holding the coils in place. 2. Steel Frames: Another option is to use steel frames, constructed with sturdy steel materials, to firmly secure the coils and prevent any movement or shifting. Steel frames are especially suitable for larger or heavier coils as they offer enhanced stability and durability. 3. Cardboard Boxes: For smaller or lighter steel coils, cardboard boxes can be a suitable choice. These boxes, made of strong and durable cardboard, provide adequate protection against minor impacts and scratches. They are also easy to handle and can be conveniently stacked or stored. 4. Plastic Wrapping: In addition to crates, frames, or boxes, steel coils can be wrapped in plastic materials for added protection. Plastic wrapping safeguards the coils from moisture, dust, and external elements during transportation and storage. This packaging option is commonly used in combination with other methods. 5. Transportation Racks: Specially designed transportation racks made of steel or other robust materials can be used for efficient handling and transport of steel coils. These racks securely hold the coils, allowing for easy loading and unloading, and ensuring enhanced safety during transit. Overall, the choice of packaging for steel coils depends on factors such as size, weight, transportation method, and desired level of protection. Manufacturers and distributors carefully consider these factors to select the most appropriate packaging solution that ensures the safe and efficient handling of steel coils throughout the supply chain.
- Q: what does steel have inside of it that makes it rust.I need the answer fast!!!!!!!!!
- Steel is made by refining iron. Iron is mined as a red powdery ore. Unfortunately, when moisture and oxygen are present, the steel attempts to revert to its original state.
- Q: Please give me the name of the steel, and the percentage of materials from what It consists, if you can give me five types of steel it will be better so I can decide. Thanks.

- Q: What are the dimensions of steel coils used in shipbuilding?
- The dimensions of steel coils used in shipbuilding can vary depending on the specific requirements of the ship and its construction. However, commonly used dimensions for steel coils in shipbuilding range from 1.5mm to 25mm in thickness and 600mm to 2000mm in width. The length of the steel coils can also vary, typically ranging from 1000mm to 6000mm. These dimensions are chosen to ensure the strength and durability of the ship's structure, while also considering factors such as weight, flexibility, and ease of handling during the construction process.
- Q: I was wondering if anyone knew the grade/type of steel for this product. I'd like to use it as stock for a knife blade, but would like to know the specs so I can determine if it is suitable and, if so, how best to heat treat it.Thanks.PS: I know it isn't stainless, but that leaves a lot of other steel types.

- Q: Why do we galvanise steel? Galvanised steel is steel coated with zinc.
- it prevents the steel from rusting. Zinc rusts too, but more slowly than steel, and it doesn't tend to eat away it's structure. Zinc coatings prevent oxidation of the protected metal by forming a barrier, and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not cause a breakdown of the substrate's surface integrity as it is formed. Indeed the zinc oxide, if undisturbed, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminium and stainless steels by their oxide layers.
- Q: How do steel coils perform in corrosive environments?
- Steel coils typically perform well in corrosive environments due to their inherent resistance to corrosion. This is primarily because steel is an alloy composed of iron and other elements, such as carbon, which provides it with a protective layer known as a passive film. This passive film acts as a barrier between the steel surface and the corrosive elements, preventing direct contact and thus minimizing the risk of corrosion. In addition to the passive film, steel coils can also be coated with various protective coatings to enhance their resistance against corrosion. These coatings, such as zinc or epoxy, provide an additional layer of protection and further extend the lifespan of the steel coils when exposed to corrosive environments. However, it is important to note that the performance of steel coils in corrosive environments can still be influenced by factors such as the specific corrosive agent, exposure duration, and the presence of other contaminants. In highly aggressive environments, such as those with high humidity, saltwater exposure, or acidic chemicals, the protective layers on steel coils may deteriorate over time, leading to potential corrosion. To ensure optimal performance in corrosive environments, it is advisable to select steel coils with corrosion-resistant properties, such as stainless steel or galvanized steel. Regular maintenance and inspections are also crucial to identify any signs of corrosion early on and take appropriate measures to prevent further damage. Overall, steel coils offer good resistance to corrosion in most environments, but the severity of the corrosive conditions can ultimately impact their performance.
- Q: I just got a set of all-clad Stainless steel frying pans, they are very nice yet they didn't come w/ instructions to care for them. I have never cooked w/ stainless steel cookware so I really don't know much about them. I was told they should have a lifetime warranty on them, but I don't want to reck them. I would appreciate any information I can get on stainless steel cookware. Thanks.
- I have stainless steel as well. i clean them like I would with any pan. however once and a while when the bottems get kind of blackened due to spillage or flames I take one of those magic eraser things to clean them up. once every 2-3 months I polish the outsides with a nice stainless steel cleaner.
