Structure of Aluminum Zinc Rolled Coil

 Prepainted aluminum zinc rolled Coil for Construction Roof

Description of Aluminum Zinc Rolled Coil
Aluminum zinc coils 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 Aluminum Zinc Rolled Coil for Construction Roof

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.

Q:How are steel coils used in the production of electrical conduits?
Steel coils are used in the production of electrical conduits in several ways. Firstly, steel coils are used as the raw material for manufacturing electrical conduits. These coils are made of high-quality steel that is specially processed and formed into a long, continuous strip. Once the steel coils are obtained, they are fed into a machine called a slitter. The slitter cuts the coils into narrower strips of the desired width. These narrower strips will serve as the base material for the electrical conduits. The next step is to shape the steel strips into the desired conduit shape. This is done by passing the strips through a series of rollers and other shaping tools. The steel strips are gradually formed into the round or rectangular shape of the conduit. The rollers apply pressure and manipulate the steel strip until it reaches the desired shape. After the shaping process, the ends of the steel strips are welded together to create a continuous conduit. This welding process ensures that the conduit will have a seamless structure, which is important for its functionality and durability. Once the conduits are formed and welded, they undergo further processing to enhance their properties. This may include processes such as galvanizing, where the conduits are coated with a layer of zinc to protect them from corrosion. This additional layer provides the conduits with increased longevity, making them suitable for various electrical applications. In summary, steel coils are essential in the production of electrical conduits. The coils serve as the raw material that is shaped, welded, and processed to create the final product. The use of steel coils ensures that the electrical conduits are strong, durable, and capable of withstanding the demands of electrical installations.
