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

- Q:Are steel coils used in the aerospace industry?
- Yes, steel coils are used in the aerospace industry. They are often utilized in the manufacturing and assembly of various aircraft components such as engines, frames, and landing gears. Steel coils provide strength, durability, and resistance to high temperatures, making them suitable for aerospace applications.
- Q:What is the difference between regular steel stainless steel? Why does steel rust but stainless wont? Is stainless some kind of alloy or something? Any knowledgeable input would be great. Thanx!
- In metallurgy, stainless steel is defined as a steel alloy with a minimum of 11.5% chromium content by mass. Stainless steel does not stain, corrode or rust as easily as ordinary steel (it stains less), but it is not stain-proof. It is also called corrosion resistant steel when the alloy type and grade are not detailed, particularly in the aviation industry. There are different grades and surface finishes of stainless steel to suit the environment to which the material will be subjected in its lifetime. Common uses of stainless steel are cutlery and watch straps. Stainless steel differs from carbon steel by amount of chromium present. Carbon steel rusts when exposed to air and moisture. This iron oxide film is active and accelerates corrosion by forming more iron oxide. Stainless steels have sufficient amount of chromium present so that a passive film of chromium oxide forms which prevents further corrosion
- Q:and also what makes different hardness of stainless steel?
- Stainless steel is formed due to other metals present, that are resistant to corrosion. The main one is chromium, which is an excellent protector. Hardness in steel is due to other metals, as well as the carbon content. Chromium, vanadium and tungsten make steel extraordinarily hard. High carbon content makes steel hard but brittle.
- Q:How are steel coils used in the manufacturing of body panels?
- Steel coils are used in the manufacturing of body panels by being fed into a stamping press. The press uses a die to shape and form the steel into the desired body panel shape.
- Q:Which one has more electrical resistivity? Wood or steel? And why?I know that the resistivity depends on the material of the conductor, but i want a perfect explaination please.Thnx in advance :)
- Steel Resistivity
- Q:What is the average flatness tolerance for steel coils?
- The average flatness tolerance for steel coils varies depending on the specific industry and application. However, in general, most steel coil manufacturers aim for a flatness tolerance of around 0.25% to 0.5% of the material's thickness.
- Q:How are steel coils processed for edge trimming or slitting during processing?
- Steel coils are processed for edge trimming or slitting during processing by using specialized machinery. The coils are uncoiled and fed through a slitting machine, which cuts the coil into narrower strips. These strips are then passed through an edge trimming machine, which removes any irregularities or excess material from the edges. This process helps to ensure that the steel coils meet the desired specifications and are ready for further processing or use in various industries.
- Q:What are the different types of steel coil handling systems?
- There are several types of steel coil handling systems, including overhead crane systems, coil grab systems, coil transfer cars, and coil tilters. Each system is designed to efficiently and safely handle steel coils in different environments and applications.
- Q:What is the difference between a steel strip and a coil? The steel strip is flat steel, and the steel coil is made of steel. Is that correct?
- A steel strip is also a coil, usually a narrow strip, also known as a steel strip. The volume is relatively wide. In addition, flat steel is usually hot-rolled out of long strip steel, fixed length 5 and 5.5,6 meters range, steel coil is Kaiping Chang 12501500, length 2.5 meters, 4 meters, 6 meters, ranging from steel plate
- Q:What are the challenges in coil blanking?
- Coil blanking, a process used to cut flat metal sheets from coiled stock, presents several challenges that need to be addressed for efficient and accurate production. Some of the key challenges in coil blanking include: 1. Material variations: Coiled stock can have variations in thickness, width, and surface quality. These variations can affect the cutting process and result in inconsistent blanks. Proper material selection and control are crucial to ensure consistent quality and dimensional accuracy. 2. Coil set and crossbow: Coiled stock often has inherent shape imperfections like coil set (longitudinal curvature) and crossbow (transverse curvature). These imperfections can cause alignment issues during the cutting process, leading to misalignment and inaccurate blanks. Specialized equipment and techniques, such as straighteners and leveling systems, are required to minimize these shape imperfections. 3. Coil edge condition: The edges of coiled stock can have burrs, waves, or irregularities, which can affect the quality and precision of the cut blanks. Adequate edge conditioning techniques, such as deburring or edge trimming, need to be employed to ensure clean and straight edges for the final blanks. 4. Slitting and shearing forces: The forces exerted during the coil blanking process can induce stresses and strains in the material, potentially leading to deformation or springback. These factors can result in dimensional variations and affect the overall quality of the finished blanks. Careful consideration of the slitting and shearing forces, along with proper tooling design and machine settings, is necessary to minimize these effects. 5. Scrap and material waste: Coil blanking can generate significant amounts of scrap material, especially during setup and adjustment phases. Managing scrap and minimizing material waste are critical challenges in coil blanking to optimize production efficiency and reduce costs. Efficient nesting algorithms and real-time monitoring systems can help optimize material utilization and minimize waste. 6. Automation and productivity: Coil blanking processes often require high-speed and high-volume production to meet market demands. Implementing automation systems, such as robotic material handling and advanced control systems, can enhance productivity. However, integrating and synchronizing these automation components with the cutting process can be challenging and requires careful planning and system integration expertise. Overall, addressing these challenges in coil blanking requires a combination of proper material selection, advanced equipment, specialized techniques, and efficient process control. By overcoming these challenges, manufacturers can achieve consistent quality, dimensional accuracy, and productivity in coil blanking operations.
