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: hi to every one I need to konw moer about steel and iron industry (process) thank you in advance for your intresting
- Primary Steel Making first Iron ore Coke Lime stone are mined and then took to the steel plant and put in the top off a blast furnace and sinks down to the bottom off the blast furnace and turns into molten iron. Once this process has been done it is then transferred to a BOS (Basic Oxygen Steel Making) this is then poured from a ladle into the BOS and a Lance is inserted into the BOS and pure oxygen is blown into the BOS for about 30 min and turns into steel.
- Q: How can I tell the wear resistance, strength, ect from the name of the steel?how could I tell the difference between 420 and 440 steel. what does the HC in 420 HC steel mean? what do the numbers and letters in s30v steel mean?
- If your question implies how to tell the differences just by looking at the actual knife then I'd say there is no real way to do that. Just about all high carbon steel's look alike. You should be able to tell the difference between a stainless steel, but which one is anybodies guess, and a carbon steel however.
- Q: What are the common methods of storing steel coils in warehouses?
- There are several common methods for storing steel coils in warehouses, depending on the size and weight of the coils, as well as the available space and resources in the warehouse. Here are some of the most commonly used methods: 1. Block stacking: This method involves stacking the steel coils directly on top of each other, forming a block. The coils are typically aligned in rows and columns, with wood or rubber blocks placed between the layers to provide stability and prevent damage. 2. Racking systems: Racks are often used to store steel coils in warehouses. There are various types of racks, including cantilever racks, coil racks, and structural racks. These racks provide a structured system for organizing and storing the coils, allowing for easy access and efficient use of space. 3. Coil cradles: Coil cradles are a type of storage equipment specifically designed for steel coils. They consist of a series of cradles or saddles that securely hold the coils in place. These cradles can be stacked on top of each other to maximize vertical space utilization. 4. Coil pads: Coil pads are flat platforms made from materials such as wood, rubber, or foam. They are placed on the warehouse floor, and the steel coils are then stacked directly on top of them. Coil pads help to distribute the weight of the coils evenly and protect them from damage caused by contact with the floor. 5. Slit coil storage: Slit coils, which are narrower and lighter than full-size coils, can be stored using specialized storage systems. These systems often consist of racks or shelves equipped with dividers or separators to keep the coils organized and prevent them from unraveling. It is important to note that regardless of the storage method used, safety precautions should be followed when handling and storing steel coils in warehouses. This includes ensuring proper weight distribution, using appropriate lifting equipment, and adhering to industry-specific guidelines and regulations.
- Q: What are the different types of steel coil finishes used in architectural applications?
- There are several types of steel coil finishes commonly used in architectural applications. These include mill finish, galvanized finish, painted finish, and stainless steel finish. Mill finish refers to the natural appearance of steel after it has been processed, which typically has a smooth, matte surface. Galvanized finish involves coating the steel with a layer of zinc to provide corrosion resistance. Painted finish involves applying a coat of paint to the steel surface, offering both protection and aesthetic appeal. Lastly, stainless steel finish involves using a steel alloy with a high percentage of chromium, resulting in a shiny and corrosion-resistant surface.
- Q: So, I'm looking into steel toe paddock boots. I'll be using them around horses, horses that I don't know and that are rescue horses. I'm currently looking at Equitector the Moorland paddock boots. They're $200, and I think I have to order them online. I like boots that are this style (the Moorland style)... Is there any other brand of boots that has steel toe paddock boots, that are cheaper or that I can buy in stores?
- Hi! You can hike in steel toed boots, but I wouldn't. They aren't designed for hiking, no matter what the manufacturers says. They're built to protect your feet from hazards on a job site. I bought my first pair of decent hiking boots for $10/month on layaway at an outfitters. It took forever, of course, but I didn't have the money to buy them right out. Until then, I hiked in a pair of tennis shoes. Sneakers are just fine as hiking gear, though remember that you will have no ankle support, so you need to be more careful on rocky trails. Use a pair you don't mind getting dirty and make sure they have decent ankle support. Also, this is a great time of year to buy boots if you can scrounge the money together. Most outfitters are swapping over to their spring lines and have shoe/boot sales going on. You don't have to use an outfitter, either. Lots of regular shoe or department stores sell boots that will work just fine until you can afford some nice top-line boots.
- Q: How do steel coils resist corrosion?
- Steel coils resist corrosion due to the protective layer formed on their surface. This layer, known as a patina, acts as a barrier between the steel and the surrounding environment, preventing moisture and oxygen from reaching the metal and causing oxidation. Additionally, steel coils can be coated with corrosion-resistant materials such as zinc or paint to further enhance their resistance to corrosion.
- Q: How are steel coils processed for cold rolling or hot rolling?
- Steel coils are first unwound and inspected for any defects. Then, they are cleaned and treated to remove any impurities. For cold rolling, the coils are passed through a series of rollers at room temperature to reduce their thickness and improve their surface finish. On the other hand, for hot rolling, the coils are heated to high temperatures and then passed through rollers to achieve the desired thickness and shape.
- Q: What are the common coil slitting methods?
- The common coil slitting methods include rotary shear, loop slitting, and double knife slitting.
- Q: How are steel coils used in the manufacturing of safety systems?
- Steel coils are commonly used in the manufacturing of safety systems as they provide strength, durability, and stability to various components. These coils are often transformed into springs, which are crucial for absorbing and distributing impact forces during accidents or sudden movements. Springs made from steel coils are utilized in seatbelt retractors, airbag systems, suspension systems, and other safety mechanisms to enhance overall safety and protect occupants in vehicles and various industrial applications.
