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: What are some characteristics of steel.
- Characteristics Of Steel Hardening. - The characteristic difference between steel and pure wrought iron is as follows: - When steel is raised to a red heat and then suddenly cooled, it becomes hard and brittle. This process, which is known as hardening, has no effect upon pure wrought iron. Tempering is a characteristic of steel which distinguishes it from cast iron. If steel has been hardened by being heated and suddenly cooled, as above described, it may be softened again by applying a lower degree of heat and again cooling. This is known as tempering. Cast iron, on the contrary, though it is hardened by the first process, cannot be softened by the second. When a bar of steel is struck it gives out a sharp metallic ring, quite different from the sound produced by striking wrought iron. Other characteristics of steel are its great elasticity and its retention of magnetism.
- Q: I got my dog those nice looking stainless steel water and food bowls (looks great next to my kitchen appliances...haha). The thing is my dog will drink from the toilet or a plastic bowl but not out of his bowl...I was wondering if those stainless steel bowls change the taste of food and water?
- Well, I know the water at this restaurants where they use metal pitchers taste a bit off to me. There's nothing wrong with the water, but I think the metal pitcher throws off the flavor. Could be the same with the metal bowl and the dog. Plastic is only a problem at hiding bacteria if it gets scratched up badly (which isn't as likely to happen with water as long as the dog doesn't chew it. You can also put the plastic crock bowls on the top shelf of a dishwasher for cleaning as the heat kills most germs.
- Q: What are the typical lead times for ordering steel coils?
- The typical lead times for ordering steel coils can vary depending on various factors such as the type and size of the coil, the supplier's production capacity, and the current market conditions. However, on average, lead times for ordering steel coils can range from a few weeks to several months. For standard-sized steel coils that are readily available in the market, lead times are generally shorter and can range from a few weeks to a couple of months. This is because suppliers often maintain a stock of these commonly used coil sizes to meet immediate customer demands. However, it's important to note that lead times can still be influenced by factors like transportation and logistics. On the other hand, if you require custom-made or non-standard steel coils, lead times can be longer. These coils usually involve additional processes such as specialized cutting, shaping, or coating, which may require more time for production. Lead times for custom-made steel coils can range from a few months to even six months or more, depending on the complexity of the specifications and the supplier's production capabilities. It's worth mentioning that lead times can also be affected by external factors like market demand and availability of raw materials. During periods of high demand or when there are supply chain disruptions, lead times may be extended as suppliers need to adjust their production schedules accordingly. To accurately determine the lead times for ordering steel coils, it is recommended to reach out to specific suppliers or manufacturers. They will be able to provide you with the most up-to-date and accurate information based on your specific requirements and the current market conditions.
- Q: How long do steel coils typically last?
- Steel coils typically last for several decades, with an average lifespan ranging from 20 to 30 years. However, the actual durability and lifespan depend on various factors, such as the quality of the steel, the environment it is exposed to, how well it is maintained, and the frequency of use.
- Q: How are steel coils inspected for paint adhesion?
- Steel coils are inspected for paint adhesion using various methods and techniques. One common method is the tape test, where a strip of adhesive tape is pressed onto the painted surface and then quickly pulled off. The tape's adhesion to the paint is then assessed by examining the amount of paint that is removed from the surface. If the paint adheres well to the steel, only a small amount of paint will be lifted off by the tape. Another method used is the crosshatch adhesion test. In this test, a series of parallel cuts are made on the painted surface using a sharp blade, creating a crosshatch pattern. A piece of adhesive tape is then applied over the cuts and quickly pulled off. The amount of paint that is removed from the crosshatched area is evaluated to determine the paint adhesion. Additionally, a visual inspection is often conducted to assess the overall appearance and adhesion of the paint. Inspectors look for any signs of cracking, peeling, or bubbling of the paint, which could indicate poor adhesion. They also check for any areas where the paint may have chipped or flaked off. Furthermore, various laboratory tests can be performed to evaluate the paint adhesion on steel coils. These tests may include techniques such as the pull-off test, where a specialized device is used to measure the force required to pull off a small section of the paint from the surface. Other tests may involve subjecting the painted surface to extreme temperature or humidity conditions to assess how well the paint holds up under different environmental factors. Overall, a combination of visual inspections, tape tests, crosshatch adhesion tests, and laboratory tests are used to thoroughly inspect steel coils for paint adhesion. These tests help ensure that the paint adheres properly to the steel surface, providing a durable and long-lasting finish.
