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.

- Q: I haven't seen Man of Steel yet, but which one do you think was better? (please no spoilers)
- Well, I haven't seen it Man of Steel but I really see it hard to believe that's better than Superman. To me, Superman with Christopher Reeve is the best movie about Superman ever made. When I first saw it I was amazed. Watching Superman flying for the first time, catching Loise and graving that helicopter before it falls... it was awesome! I loved it! The other movies that followed were bad but this one was amazing. I've seen what other actors have made with the character, but I believe Christopher was the best. He was the perfect man, the perfect gentleman and the best superhero ever. I know that this Superman is for the new generations so it will be more 'real' and more 'suffered' or will have more personal issues dealing with his origins and blah blah blah... and I wish him good luck, but honestly? I stick to the original Superman because whenever I see Christopher Reeve flying around the planet as Superman (hanging from wires-no CGI people!) and I hear that characteristic music I just melt and I'm a child once more. So good luck to the new generation, I really hope they like this new guy and new story, but I'm more than fine with the original version, thank you. Hope it helps! ;)

- Q: How do steel coils compare to aluminum coils?
- Steel coils are generally stronger and more durable than aluminum coils. They have a higher tensile strength and better resistance to impact and abrasion. However, aluminum coils are lighter, more corrosion-resistant, and have better thermal conductivity. The choice between steel and aluminum coils depends on the specific application and the desired characteristics such as strength, weight, and corrosion resistance.
- Q: What are the different methods of edge camber correction for steel coils?
- There are several methods used for edge camber correction in steel coils, depending on the specific requirements and equipment available. Some of the common methods include: 1. Mechanical Edge Trimming: This method involves trimming the edges of the coil using mechanical tools such as shears or slitters. It helps to remove excess material and correct the camber. This method is often used for smaller coils or when the camber is minimal. 2. Tension Leveling: Tension leveling is a process where the coil is passed through a series of adjustable rollers under tension. The tension helps to elongate the steel and reduce the camber. This method is effective for correcting moderate camber and is commonly used for larger coils. 3. Roller Leveling: Roller leveling is similar to tension leveling, but instead of adjustable rollers, the coil is passed through a series of fixed rollers. These rollers exert pressure on the steel to flatten it and correct the edge camber. This method is often used for thicker and heavier coils. 4. Heat Straightening: Heat straightening involves applying controlled heat to the edges of the coil to soften the steel. Once the steel becomes malleable, external force is applied to straighten the edges. This method is suitable for correcting severe edge camber but requires specialized equipment and expertise. 5. Combination Methods: In some cases, a combination of different methods may be used to achieve the desired edge camber correction. For example, mechanical edge trimming may be followed by tension leveling or roller leveling to further straighten the edges. It is worth mentioning that the choice of method depends on various factors such as the severity of camber, coil dimensions, material properties, and available equipment. It is essential to evaluate these factors and consult with experts to determine the most suitable method for edge camber correction in steel coils.
- Q: How are steel coils cleaned before use?
- Steel coils are cleaned before use through a process known as pickling. Pickling is a chemical treatment that helps remove any impurities, scale, rust, and other contaminants from the surface of the steel coils. The initial step involves the steel coils being immersed in an acid bath, typically a mixture of hydrochloric acid and sulfuric acid. This acid solution helps dissolve any rust, scale, and other surface impurities. The duration of the immersion depends on the extent of contamination and the desired cleanliness level. After the pickling process, the coils are thoroughly rinsed with water to remove the acid solution and any remaining residue. This step is crucial to prevent further corrosion or chemical reactions. Once the rinsing is complete, the coils are often subjected to a drying process to remove any remaining moisture. This can be done through air drying, using high-pressure air blowers, or by passing the coils through heated chambers. After the cleaning process, the steel coils are now ready for use in various applications such as manufacturing, construction, or any other industry that requires high-quality steel products. The pickling process ensures that the coils have a clean, smooth, and corrosion-resistant surface, allowing them to perform effectively and meet the desired specifications.
- Q: What are the common coil processing equipment used in the industry?
- Some common coil processing equipment used in the industry include coil slitting machines, coil leveling machines, coil cutting machines, coil recoiling machines, and coil feeding systems.
