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 do steel coils perform in extreme weather conditions?
- Steel coils are designed to withstand extreme weather conditions due to their durability and strength. They are often coated or galvanized to protect against corrosion, making them highly resistant to rust and other forms of weather damage. Additionally, the structural integrity of steel coils allows them to withstand high winds, heavy precipitation, and temperature fluctuations without significant deformation or damage.
- Q:i mean the properties include the elasticity, impact load and ductility. am doing assignment about the perfect material that should be possessed by spring and i found alloy steel is the perfect and am confused whether stainless steel is the same with alloy steel ?
- Is Stainless Steel An Alloy
- Q:What are the common coil storage methods?
- The common coil storage methods include stacking in a vertical or horizontal position, using coil cradles or racks, and utilizing coil drums or shafts for secure storage.
- Q:How are steel coils used in the production of shelving units?
- Steel coils are used in the production of shelving units by being cut, shaped, and formed into the necessary components such as uprights, shelves, and brackets. These coils are unrolled and fed into machines which use different processes like stamping, bending, and welding to transform them into the desired shelving parts.
- Q:I just bought some cheap earrings from this beauty supply store but they said surgical steel So will they prevent my ears from bleeding / infection ?
- Surgical steel is a grade of steel often used in medical appliances like tweezers, forceps, etc. It's generally non-reactive and considered very safe. It doesn't contain any special properties against infection--you still have to observe basic hygiene and clean your piercings properly--but most people can wear surgical steel earrings without a problem. However, if you have a contact allergy to base metals like nickel, surgical steel may cause redness or irritation because of the metals used in it. If cheap rings or necklaces make your skin break out in a rash you should NOT wear surgical steel.
- Q:How are steel coils used in the manufacturing of suspension systems?
- Steel coils are used in the manufacturing of suspension systems as they provide the necessary support and flexibility to absorb shocks and vibrations, ensuring a smooth and comfortable ride. These coils are typically used in coil spring suspension systems, where they are compressed and stretched to absorb and distribute the weight of the vehicle, maintaining stability and enhancing overall performance.
- Q:What are the different grades of steel used in coil manufacturing?
- There are several grades of steel used in coil manufacturing, including low carbon steel, high carbon steel, stainless steel, and alloy steel. Each grade has its own unique properties and is chosen based on the specific requirements of the application, such as strength, corrosion resistance, or heat resistance.
- Q:i recently got an industrial piercing and instead of getting pierced with a metal bar i have a PTFE bar .. i eventually want to put in a metal bar but what kind do i get? whats the difference between a surgical steel and titanium bar?thanks
- Surgical steel is fine, titanium is by far the most superior metal though. I've found that piercings done with titanium as opposed to surgical steel have healed a lot easier. But keep in mind that if you just got the piercing you've got quite some time before you'll be able to change it.
- Q:How do steel coils contribute to the agricultural sector?
- Steel coils contribute to the agricultural sector by being used in the manufacturing of agricultural machinery and equipment. These coils are used to create components such as plows, harrows, tillers, and seeders, which are essential for cultivating, planting, and harvesting crops. The durability and strength of steel coils make these agricultural machinery and equipment more robust, reliable, and efficient, thereby improving productivity and ensuring higher crop yields.
- Q:What are the advantages of using hot-rolled steel coils?
- Hot-rolled steel coils offer several advantages, including improved strength, durability, and formability. The high temperature during the rolling process allows for better shaping and molding, making it suitable for various applications. Additionally, hot-rolled steel coils have a smoother surface finish and are more cost-effective compared to cold-rolled steel coils.
