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 transported and stored?
- Steel coils are typically transported using flatbed trailers, coil carriers, or railcars. These coils are securely strapped or banded to prevent movement during transportation. Once they reach their destination, they are usually stored in warehouses or outdoor storage yards. The coils are stacked on top of each other, often with the help of specialized equipment, to optimize space utilization. They may also be stored horizontally on racks or stored vertically in specially designed coil racks. Proper handling and storage procedures are followed to ensure the safety of personnel and to prevent damage to the steel coils.
- Q: Want to get stainless steel sink. I want quality, durability, quiet, etc. Any suggestions??
- Yes, it’s a good idea to look for the best brand of stainless steel sink as it is used in various purposes regularly. Top brand of stainless steel is naturally longer lasting and capable of bearing lot of pressure then normal stainless steel sink. You must see top brands as well as their prices before buying any.
- Q: Are steel coils used in the aerospace industry?
- Yes, steel coils are used in the aerospace industry for various applications such as manufacturing aircraft components, structural parts, and engine components.
- Q: Can't find it- this is for a physics experiment for youngs modulus done with a steel wire.
- It is the Yield Strenght that you are looking for...that is another word for elastic limit. AND, for steel, it does depend on the variant of steel. Not all types of steel are identical, since steel isn't a pure substance. For Young's modulus (and other stiffness properties), just about all variants have the same values. However, for strength properties like Yield strength and ultimate strength and fatigue strength, it does depend on variant, and is precisely why different recipies exist in AISI standards.
- Q: What are the challenges in coil recoiling?
- Some of the challenges in coil recoiling include achieving precise and consistent coiling, minimizing coil distortion and tangling, preventing material damage or breakage during recoiling, and ensuring efficient and safe handling of coiled materials. Additionally, factors such as coil size, weight, and material properties can also pose challenges in the recoiling process.
- Q: What are the different methods of oiling steel coils?
- There are several methods of oiling steel coils, including applying oil by roll coating, using a spray system, or immersing the coils in an oil bath.
- Q: I have a steel plate 3' long x 2 wide x 3/16 thick. I have a 1/2 diameter hole with the center 3/4 from the end. Tensile strength is 38,000psi. A chain goes through the hole and is connected to a load. how does one determine how much tension the chain can have before it rips through the hole?
- Assuming that the chain can take the breaking load of the plate, the plate will fail at the area between the hole and the end, in double shear. The shear strength of the material should therefore be known for us to be able to calculate the breaking force. Approximately, the shear strength of steel is about 60% of the tensile strength. For ordinary mild steel the tensile strength is about 60,000 psi, not 38,000 psi. 38,000 psi is just about the yield point of mild steel. Using 60,000 psi tensile strength, the approximate shear strength of steel therefore is 36.000 psi. The net area between the hole and the end of the plate is: A = 3/16(3/4 - 1/4) = 0.09375 in^2 The force necessary to rip through the area which is also the tension on the chain is: T = 2 x 0.09375 x 36,000 = 6750 lbs
- Q: How can steel coils be recycled?
- Steel coils can be recycled by first removing any contaminants or coatings from the surface. The coils are then shredded into smaller pieces and melted in a furnace. The molten steel is then formed into new coils or other steel products.
- Q: What is the difference between hot rolled and cold rolled steel coils?
- The main difference between hot rolled and cold rolled steel coils is the process by which they are made. Hot rolled steel coils are produced by heating the steel above its recrystallization temperature, allowing it to be easily shaped and formed. This process results in a rougher surface finish and less precise dimensions. On the other hand, cold rolled steel coils are produced by further processing hot rolled coils through a series of rolling mills at room temperature. This process results in a smoother surface finish, tighter tolerances, and improved mechanical properties.
- Q: How do steel coils contribute to energy savings in buildings?
- Steel coils contribute to energy savings in buildings in several ways. Firstly, steel coils are often used as part of the insulation system in buildings. The high thermal conductivity of steel allows for efficient heat transfer, ensuring that the building remains well-insulated and energy loss is minimized. Additionally, steel coils are often used for HVAC systems, which play a crucial role in energy efficiency. By using steel coils in these systems, the heat transfer process can be optimized, reducing the energy required to heat or cool the building. Moreover, steel coils are durable and long-lasting, reducing the need for frequent replacements and maintenance, which in turn saves energy and resources. Overall, the use of steel coils in buildings helps to improve energy efficiency and reduce energy consumption, contributing to significant energy savings.
