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: How are steel coils used in the manufacturing of metalworking tools?
- Steel coils are used in the manufacturing of metalworking tools by being formed and shaped into various components such as blades, cutting edges, and handles. These coils serve as the primary raw material, which is then processed and treated to create durable and high-quality tools that can withstand the rigors of metalworking processes.
- Q: How are steel coils used in the manufacturing of household appliances?
- Steel coils are used in the manufacturing of household appliances as they are shaped, cut, and formed into various parts such as panels, frames, and components. These coils provide strength, durability, and structural integrity to appliances like refrigerators, ovens, and washing machines, ensuring their stability and longevity.
- Q: Myself, iam Working In a Steel Fabrication Company. I completed my Engineering in 2006 and immediately recruited in this company in Oman. My company is Steel Fabrication company .So as i am new to this field, i just need some basic knowledge regarding this Steel Fabrication.Waiting for ur early reply.
- Steel fabrication involves the joining together of different types and sizes of steel members e.g when you are constructing a truss. This will include welding or bolting together those members as specificified on engineering drawings though sometimes you have to design/provide a suitable connection yourself. You have to ensure that all connections are adequate/ will not fail in service. You will also have to produce steel fabrication drawings showing various details and these you will send to the design engineer for his approval before you commence the actual fabrication.
- Q: What are the common methods of joining steel coils?
- There are several common methods used for joining steel coils, depending on the specific application and desired outcome. 1. Butt welding: This is a commonly used method where the two ends of the steel coils are aligned and welded together. Butt welding can be done using various techniques such as gas welding, electric resistance welding, or laser welding. This results in a strong and continuous joint without any additional material. 2. Overlapping and stitching: In this method, one end of the steel coil is overlapped onto the other end, and then stitched together using mechanical fasteners like staples, nails, or screws. This technique is suitable for temporary or low-stress applications where disassembly may be required. 3. Mechanical coupling: Steel coils can also be joined using mechanical couplings. These couplings are typically designed to fit over the ends of the coils and securely hold them together. Mechanical couplings are commonly used in pipelines, where the joint needs to be leak-proof and withstand high pressure. 4. Adhesive bonding: Another method of joining steel coils is through the use of adhesives. This involves applying a suitable adhesive or bonding agent to the ends of the coils and then pressing them together. Adhesive bonding allows for a clean and aesthetically pleasing joint, but its strength may vary depending on the adhesive used. 5. Overlapping and welding: Similar to overlapping and stitching, this method involves overlapping the ends of the steel coils and then welding them together. However, instead of using mechanical fasteners, welding is used to create a stronger and more permanent joint. This method is commonly used in structural applications where high strength and durability are required. It is important to note that the choice of joining method depends on factors such as the type of steel, the application requirements, and the desired strength of the joint. Proper consideration should be given to ensure the selected method is suitable for the specific project.
- Q: How are steel coils used in the manufacturing of storage cabinets?
- Steel coils are used in the manufacturing of storage cabinets by being processed and formed into sheets, which are then cut, shaped, and welded together to create the structural framework and outer shell of the cabinets.
- Q: I'm getting microdermals, from a very experienced piercer, but they don't have titanium and I know titanium is the best for this, but is Grade A Srugical Steel okay too?(P.S. also instead of getting flat heads, of the microdermals, I'm getting flat crystal like ones, are those okay? I know to be careful, I am veryyyy careful with my body, so much that I'm worried I'm going to overly do it when I get them and dry out the skin or something hahaa xp)THANK YOU ALL IN ADVANCE FOR THE HELP
- surgical steel is fine. if you really want titanium ask your piercer if you can buy them yourself and if he can use them. the diamond kind will be okay especially if you are the careful type :)
- Q: Can steel coils be used in high-temperature applications?
- Yes, steel coils can be used in high-temperature applications. Steel is known for its excellent strength and resistance to heat, making it a suitable material for various industrial processes that involve high temperatures. It can withstand and maintain its structural integrity even under extreme heat conditions.
- Q: How are steel coils used in the manufacturing of railway tracks?
- Steel coils are used in the manufacturing of railway tracks to produce high-quality and durable rails. These coils are unwound and undergo a series of processes such as rolling, heating, and shaping to form long, straight sections of rail tracks. The steel coils provide the necessary strength and flexibility required to withstand the heavy loads and constant stress of trains running on the tracks.
- Q: What are the main factors that affect the strength of steel coils?
- The main factors that affect the strength of steel coils are the composition of the steel, the manufacturing process, and the heat treatment applied.
- Q: What are the different types of corrosion protection for steel coils?
- There are several different types of corrosion protection for steel coils, including galvanizing, paint coatings, organic coatings, and metallic coatings. Each method provides a barrier between the steel surface and the corrosive environment, preventing or slowing down the corrosion process. Galvanizing involves applying a layer of zinc to the steel surface, while paint coatings use various types of paints or primers. Organic coatings utilize polymers or resins to form a protective layer, and metallic coatings such as tin or aluminum can also be applied. The choice of corrosion protection method depends on factors such as the specific corrosive environment, desired lifespan, and cost considerations.
