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 formed into specific shapes?
- Coil slitting and coil forming are the two processes used to shape steel coils into specific forms. In coil slitting, a large steel coil is unwound and passed through rotating circular blades that cut it into narrower strips of the desired width. These strips are then rewound into smaller coils called slit coils. Once the steel strips have been slit, they can undergo coil forming to achieve the desired shapes. Coil forming involves various processes such as roll forming, stamping, bending, or pressing. Roll forming gradually shapes the steel strip by passing it through a series of rollers designed to bend it in specific ways. Stamping, on the other hand, uses a die and a press to cut or shape the metal into intricate forms. This method is preferred when high precision is necessary. Bending and pressing are also employed to manipulate the steel strip into desired curves or angles. Bending utilizes machines or tools to apply force, while pressing employs hydraulic or mechanical presses to shape the steel strip according to the mold or die design. In conclusion, the formation of steel coils into specific shapes involves both coil slitting and coil forming techniques. These techniques, including roll forming, stamping, bending, and pressing, enable manufacturers to transform steel coils into various shapes and profiles, catering to different applications in industries such as construction, automotive, and manufacturing.
- Q: What metals contain steel? It can be anything except soft iron or steel.
- tricky situation. look from google. it may help!
- Q: I am looking to weld some stainless steel using stainless electrodes. I was told that the arc welder needs to be able to run in DC in order to be able to weld stainless steel. Is this true? Or can you weld stainless steel with stainless electrodes with AC also?
- Stainless Steel Stick Welding
- Q: 2 refridgerator of similar model and same brand..one is stainless steel...the other is clear steel (cheaper)..so wat's the difference between the two?
- In okorder /... The appliances that are not made of stainless steel are made of a mild steel which is then finished with a durable enameled finish, in colors even. Stainless steel appliances look very nice in the showroom, but it is no fun trying to keep them fingerprint and handprint free. If you have ever owned a toaster that was made from stainless steel then you know how much fun it would be to have to keep a whole refrigerator fingerprint free, The oils transferred from the skin leave very distinct smears on stainless surfaces.
- Q: How are steel coils loaded onto trucks or containers?
- Steel coils are typically loaded onto trucks or containers using specialized equipment such as coil lifters or coil hooks. These devices safely secure the coils and allow them to be lifted and positioned onto the truck or container. The coils are then secured in place using straps or other restraints to prevent them from shifting during transportation.
- Q: How are steel coils used in the production of heating systems?
- Steel coils are typically used in the production of heating systems as a key component in heat exchangers. The coils provide a large surface area for heat transfer, allowing for efficient heating of air or water. They are often used in furnaces, boilers, and air conditioning units, where they help to transfer heat from a heat source to the surrounding environment or distribute it throughout a building.
- Q: What are the different grades of steel coils?
- There are several different grades of steel coils, including low carbon steel, medium carbon steel, high carbon steel, stainless steel, and galvanized steel. Each grade has its own unique properties and is used for specific applications based on factors such as strength, corrosion resistance, and formability.
- Q: How are steel coils used in the manufacturing of railway tracks?
- Steel coils are used in the manufacturing of railway tracks as they are processed into long, continuous lengths of steel rails. These coils are first uncoiled and then passed through a series of machines that shape, cut, and weld them together to form the required lengths and profiles of railway tracks.
- Q: what is the refining process doing to raw materials in steel
- Refining process for steel include burning out the extra carbon and impurities with oxygen lancing and protecting the steel from atmospheric gas inclusion by protective environment during such process . Measured % of ferralloys are also added to produce various grades of steel . These may be done in induction furnace/ laddle refining furnace / crucibles converters etc.
- Q: How did the growth of the steel industry influence the development of other industries?
- At least three ways: 1. Steel as a material that other industries could use to do things that couldn't be done before (for example, construction (skyscrapers, long bridges, etc.)) or could now be done at much lower cost and hence increased the size of the industry (automobiles, bearings, etc.)
