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.

- Q: Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
- In order to prevent rusting in the process of storage or transportation of steel roll, steel mills generally take the following packing: inner gas antirust paper wrapped with tape wrapped in plastic film sealing, intermediate, involute cardboard seal lining, cardboard corner, with iron and steel outer package corner protector, strapping fixed. If the inner package seal, so the steel coil is sank into the water, will not rust out.
- Q: Can steel coils be coated with organic materials?
- Yes, steel coils can be coated with organic materials. Organic coatings such as paints, polymers, or other protective substances can be applied to steel coils to enhance their appearance, provide corrosion resistance, or offer other desired properties.
- Q: How are steel coils inspected for bendability?
- Steel coils are inspected for bendability using a variety of methods to ensure their suitability for various applications. One common inspection method is the 3-point bend test, where the coil is subjected to a bending force at three specific points along its length. This test helps determine the coil's resistance to bending without fracturing or breaking. During the 3-point bend test, the coil is placed on a support system with two fixed points and one movable point. A force is then applied to the movable point, causing the coil to bend. The amount of force required to achieve a specific level of bending is measured and compared against acceptable standards. Another method used for inspecting steel coils is the mandrel bend test. In this test, a mandrel of a specific diameter is inserted into the coil and bent to a specified angle. The coil is then examined for any signs of cracking or deformation. This test helps determine the coil's flexibility and ability to withstand bending without damage. Visual inspection is also an important part of the inspection process. Trained inspectors visually examine the coil for any visible defects such as cracks, deformations, or irregularities. They also check for proper coil dimensions and uniformity throughout. In addition to these methods, non-destructive testing techniques like ultrasonic testing or magnetic particle inspection may be used to detect any internal defects or flaws that may affect the bendability of the coil. Overall, a combination of mechanical testing, visual inspection, and non-destructive testing methods are employed to ensure that steel coils meet the required bendability standards. These inspections help ensure the quality and reliability of the steel coils for various industries where bendability is a critical factor.
- Q: How are steel coils used in the production of wind turbine components?
- Steel coils are used in the production of wind turbine components for their strength and durability. These coils are typically formed into various shapes and sizes to create structural elements such as towers, frames, and foundations. The steel coils are also used to manufacture critical parts like rotor blades, gearboxes, and generator housings, ensuring the turbines withstand harsh environmental conditions and operate efficiently.
- Q: How are steel coils used in the manufacturing of storage cabinets?
- Steel coils are used in the manufacturing of storage cabinets as they provide the raw material for forming the cabinet's metal components. Coils are unrolled, cut, and shaped into the necessary panels, shelves, and doors, which are then assembled to create the cabinets. The strength and durability of steel make it an ideal material for these cabinets, ensuring they can safely store and organize various items.
- Q: What are the main characteristics of steel coils?
- The main characteristics of steel coils include their high strength and durability, flexibility, corrosion resistance, and ability to be easily formed and shaped. They are also known for their uniformity, as they are typically manufactured to precise dimensions and tolerances. Additionally, steel coils have excellent conductivity properties and are commonly used in various industries such as automotive, construction, and manufacturing.
- Q: How are steel coils used in the production of industrial boilers?
- Steel coils are used in the production of industrial boilers as they are fabricated into various components such as tubes, headers, and drums. These coils provide strength and durability to withstand high pressure and temperature conditions in boilers. Additionally, the coils are often used for heat exchange purposes, ensuring efficient transfer of thermal energy within the boiler system.
- Q: which type of carbon steel does not have manganese
- None. Mn is a trace impurity in all steels, if you look carefully enough. If you want to find a steel where Mn is not intentionally added, start looking at the alloy composition specifications, there are hundreds of steels. Why are you worried about Mn? Mn is typically added to steels for a very good reason.
- Q: Hey everyone.I have a whetstone and a honing steel. I purposely tried to make one of my knives less sharp twice to see how well the whetstone and honing steel would work.It even seemed that when I was using my whetstone it wasn't as sharp as it was when I used my honing steel, but when I also used my honing steel after having sharpened my knife on the whetstone, it was razor sharp.I was wondering, is the whetstone only supposed to be used when the knife edge isn't as flat anymore or something? Like, only when it doesn't really have an edge anymore?Please explain your answer.Thanks everyone.
- You're not supposed to use the whetstone alone. It leaves a burr, which the steel removes. If you google using a whetstone, you'll see plenty of info. It is possible to use a finer stone in place of the steel.
- Q: I would like to know the process of making steel from the mining of ore to the final product. Can anybody offer some help? Either where to look, or the process itself. I would like to have included the different options with which to make steel. Through scrap metal, or iron ore briquettes etc... Thanks.
- How is steel made? Steel is made via two basic routes - from raw materials - iron ore, limestone and coke by the blast furnace and basic oxygen furnace route or from scrap via the electric arc furnace (EAF) method. The raw material approach is known as the integrated route and about 60% of steel produced today is made by this method. The second technique is much easier and faster since it only requires scrap steel. Recycled steel is introduced into a furnace and re-melted along with some other additions to produce the end product. About 34% of steel produced in 2003 was produced via the EAF route. The first lin contains diagrams of the process (Making Steel)
