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

- Steel coils are used in the production of steel rings by being fed through a machine that cuts and shapes the coil into individual rings. These rings can then be further processed and manipulated to create a wide range of steel products, such as bearings, pipe fittings, or automotive components.
- Q: What are the different methods of punching steel coils?
- For punching steel coils, there are several methods available that vary depending on specific requirements and desired outcomes. The following are some commonly used methods: 1. Mechanical Punching: To create holes in the steel coil, a mechanical press is employed. This method involves utilizing a punch and die set, where the coil is subjected to force from the punch to create the hole. Mechanical punching is best suited for small to medium-sized holes and finds frequent use in high-volume production settings. 2. Hydraulic Punching: In hydraulic punching, hydraulic pressure is utilized to drive the punch into the steel coil. This method is commonly employed for punching larger holes or shapes that demand greater force. Hydraulic punching machines offer precise control and can handle thicker and harder materials. 3. Laser Cutting: Laser cutting is a non-contact technique that employs a laser beam to cut through the steel coil. By directing a focused laser beam onto the coil, the material is melted and evaporated to form the desired shape or hole. Laser cutting provides high precision and can be used for complex shapes and patterns. 4. Plasma Cutting: Plasma cutting involves the use of a high-velocity jet of ionized gas (plasma) to melt and remove the steel coil material. This method is suitable for cutting thicker steel coils and is often employed for larger holes or irregular shapes. 5. Waterjet Cutting: Waterjet cutting uses a high-pressure jet of water mixed with abrasive particles to cut through the steel coil. This method is versatile and can effectively cut various materials, including steel. Waterjet cutting is renowned for its high precision and clean cuts. Each method of punching steel coils possesses its own advantages and considerations. Factors such as material thickness, desired precision, production volume, and cost will determine the most suitable method for a specific application.
- Q: What is the typical lead time for ordering steel coils?
- The typical lead time for ordering steel coils can vary depending on factors such as supplier availability, production capacity, and shipping logistics. However, it is common for lead times to range from a few weeks to a few months. It is important to communicate with the supplier directly to get an accurate estimate for the specific order.
- Q: What are the different coil packaging options available for steel coils?
- There are several coil packaging options available for steel coils, including wooden crates, steel strapping, steel or plastic banding, shrink wrap, and stretch film. These packaging materials help protect the steel coils during transportation and storage, preventing damage from moisture, corrosion, and shifting.
- Q: Does anyone know if there is any info on Steel Manufacturing techniques, utilyzing electro/mechanical methods in order to create carbon nanotubes from the %C already inherant in the steel. In other words just modifying the Geometry of the Carbon the already makes up some of the steel.
- I don't think that would work. First off, there's not enough carbon in steel - even very high carbon steels are only about 2% carbon. Second, the iron atoms in steel form a crystal lattice, in the shape of a cube, with another iron atom in the middle of the cube. Each cube is about 0.3 nm per side. Carbon atoms work their way into the crystals and displace the iron atoms. But a carbon nanotube is around 1 nanometer in diameter - that's 3 times as big as the iron lattice! So a nanotube wouldn't fit. One thing you might do, however, is make a composite - mix the materials together on a scale a little bigger than the atomic scale that the iron and carbon mix to make steel. Just like a carbon fiber bicycle frame or ski pole is strands of carbon (much bigger and not as strong as nanotubes) held together with epoxy, you could hold nanotube strands together with metal. Not sure it would be good for armor, but if you can figure out a way to do it, I'm sure someone will come up with a use for it!
- Q: What is the difference between hot-rolled and cold-rolled steel coils?
- Hot-rolled steel coils are produced at high temperatures, resulting in a rough surface and less precise dimensions. Cold-rolled steel coils, on the other hand, are processed at lower temperatures, leading to a smoother surface and more accurate dimensions.

- White steel is a common shorthand name for white paper steel (shirogami hagane) which can be any of several fairly simple high carbon, water hardening steel grades. The carbon content varies by grade, and runs from 0.8 to 1.4%. The range of carbon content within a grade is a tight 0.1%. For example, the carbon content of Shirogami Hagani No1A is specified to be between 1.3 and 1.4%. Each grade also contains 0.1-0.2% silicon and 0.2-0.3% manganese, and only trace amounts of the impurities sulfur and phosphorus. Blue paper steel (aogami hagane) is also offered in several grades, with carbon content ranging similarly to the white grades. However, blue steel contains the additional alloying elements chromium and tungsten, and one grade (aogami super) also contains molybdenum and vanadium. The blue steels can be quenched in water or oil, whereas most of the white grades need a faster quench and require water.
