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 manufacturing of metalworking tools?
- The manufacturing of metalworking tools heavily relies on steel coils, which are an essential component in the process. These coils, typically made from high-quality steel, serve various purposes at different stages of production to produce a variety of metalworking tools. Blades and cutting tools, for instance, are one primary application of steel coils in metalworking tool manufacturing. These coils are usually cut into specific lengths and then shaped and sharpened to create blades used for cutting, shaping, and milling different metals. The use of high-quality steel in these coils guarantees durable, strong blades capable of withstanding the demanding conditions of metalworking processes. Another use of steel coils in metalworking tool manufacturing is for the production of drill bits and other types of tooling. The coils are shaped and machined to achieve the desired size and shape of the tool, followed by a hardening and tempering process to enhance their strength and durability. This ensures that the resulting tools can endure the high-speed drilling and cutting operations involved in metalworking. Additionally, steel coils are utilized to construct the bodies and handles of metalworking tools. The coils are typically formed into the desired shape and size using various techniques like bending, rolling, and stamping. These formed pieces are then welded or fastened together to create the final structure of the tool. The high-quality steel used in the coils ensures that the resulting tool bodies and handles possess strength, rigidity, and the ability to withstand the forces and vibrations associated with metalworking operations. In summary, steel coils are crucial in the manufacturing of metalworking tools as they are used to create blades, drill bits, bodies, and handles. These coils provide the necessary strength, durability, and precision required in metalworking processes. Considered an essential raw material, steel coils enable the production of high-quality, reliable, and efficient metalworking tools.
- Q: What are the common methods of forming steel coils?
- There are several common methods for forming steel coils, each with its own unique advantages and applications. The most common method is known as hot rolling. This involves heating a large steel slab to a high temperature and passing it through a series of rollers to reduce its thickness. The steel is then coiled into a large, continuous roll. Hot rolling is typically used for producing steel coils with a consistent thickness and a smooth surface finish. It is commonly used in industries such as automotive, construction, and manufacturing. Another method is cold rolling, which is similar to hot rolling but is performed at room temperature. Cold rolling involves passing the steel through a set of rollers to further reduce its thickness and improve its surface finish. This process is often used to produce steel coils with precise dimensions and excellent mechanical properties. Cold-rolled steel coils are commonly used in applications that require high strength, such as in the production of appliances, electrical components, and structural components. A third method is known as galvanizing. This involves coating the steel coil with a layer of zinc to protect it from corrosion. The steel coil is first cleaned and then immersed in a bath of molten zinc. The zinc adheres to the surface of the steel, forming a protective layer. Galvanized steel coils are widely used in outdoor applications, such as roofing, fencing, and automotive parts, due to their excellent corrosion resistance. Lastly, there is the electro-galvanizing method. This process involves applying a thin layer of zinc to the surface of the steel coil through an electroplating process. The steel coil is immersed in an electrolyte solution and an electric current is passed through it, causing the zinc to deposit onto the surface of the steel. Electro-galvanized steel coils are commonly used in industries that require a smooth and aesthetically pleasing finish, such as in the production of appliances, automotive parts, and decorative items. Overall, these common methods of forming steel coils provide a wide range of options for different applications and requirements. Whether it is hot rolling, cold rolling, galvanizing, or electro-galvanizing, each method offers unique benefits in terms of strength, durability, surface finish, and corrosion resistance.

- Q: We have to do a project for school on steel mines and i need 4 PROPERTIES OF A STEEL MINE PLEASE HELP!!! URGENT!!!
- There's no such thing as a Steel mine - steel is made from various raw materials (and now recycled metals). These materials may be mined separately and then combined at a steel mill - but steel is made, not mined. Steel, depending on what final characteristics they're trying to develop (strength, hardness, finish , etc.) can be comprised of iron, carbon, manganese, phosphorus, sulfur, nickel, chromium, etc. in varying quantities.
- Q: Apparently, this has to do something with electrochemical cells.
- Steel wool is a mild abrasive. I don't know what it is you are cleaning, but it is probably to remove any coating or oxidisation from the metal. Maybe you are using a metal for an electrode (perhaps a steel nail pushed into a lemon?).
- Q: How are steel coils used in the production of metal signage?
- The production of metal signage relies heavily on steel coils, which are indispensable components. These coils are typically crafted from top-notch steel and are available in various dimensions and widths.
