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.
5.Others:vending machine; game machine; etc.

- Q:What are the challenges faced in the recycling of steel coils?
- One of the main challenges in recycling steel coils is the process of separating the different materials that may be attached to the coils, such as plastic or paper. These contaminants need to be removed before the steel can be recycled efficiently. Additionally, the size and weight of steel coils can pose logistical challenges in terms of transportation and storage. Lastly, ensuring that the recycled steel meets the required quality standards and specifications is another challenge faced in the recycling process.
- Q:How are steel coils used in the production of steel framing systems?
- Steel coils are used in the production of steel framing systems as they are the primary raw material. These coils are unwound and fed into a roll forming machine, where they are shaped into the desired profiles and lengths. The steel framing systems, including studs, tracks, and joists, are then fabricated from these formed coils, providing structural support and stability to buildings and structures.
- Q:Are steel coils resistant to rust and corrosion?
- Steel coils exhibit resistance to rust and corrosion. Typically, these coils are crafted from either carbon steel or stainless steel, both of which possess exceptional properties for combating corrosion. Carbon steel coils are frequently coated with a protective layer, such as zinc or a polymer coating, to augment their resistance to rust and corrosion. Conversely, stainless steel coils possess inherent corrosion-resistant qualities due to the presence of chromium. This element creates a protective oxide layer on the steel's surface, effectively preventing rust and corrosion. Nonetheless, it is crucial to acknowledge that the extent of resistance may also hinge on the specific grade and quality of the steel employed in the coils, as well as the environmental conditions to which they are exposed.
- Q:How are steel coils used in the production of electrical resistors?
- Steel coils are used in the production of electrical resistors as they provide a conductive material that can withstand high temperatures. The steel coil is wound into a spiral shape to increase the length of the wire, which in turn increases the resistance. This allows the resistor to regulate the flow of electric current in a circuit, providing the desired level of resistance.
- Q:I need to identify a metal. It is rusty so I suspect it is either iron or steel. Since they both have similar densities and are magnetic, how do I tell the difference betweeen steel and iron?
- Iron is a natural ore. Google: Iron ore, click on Mineral Information Institute - Iron Ore. Steel is a man-made material, consisting of iron. Google: Sir Henry Bessemer, inventor.
- Q:I have some steel wool and a charged 9V Battery, when I connect 2 wires to the battery, then touch the wool with the ends of the wires the wool instantly starts burning, but when I connect 2 wires to the piece of steel wool (a new piece not same one of course) and touch the battery with the ends of the wire nothing happens (see image...)

- Q:What is the maximum stacking height for steel coils?
- The maximum stacking height for steel coils depends on various factors such as the weight and size of the coils, the strength of the supporting structure, and the safety regulations and guidelines in place. It is recommended to consult the manufacturer's specifications and industry standards to determine the appropriate maximum stacking height for steel coils in a specific situation.
- Q:steel of beam has been rusted ,how can i repair it?
- The rust needs to be removed by what ever means works best for your situation.. Often a twisted wire wheel on a 4 1/2 angle grinder works quickly... a hand wire brush may work well for you, or just plain sandpaper and a LOT of elbow grease (hard work) will remove the rust. From there, a coat of primer paint made for steel. Any hardware store in your area would have such a primer, in quart cans or spray cans. Once that is dry (a good 24 hours for most formulations), you can spray or brush paint the beam most any color you wish.. I've had very good luck with acrylic enamel paints for such projects.. IF your steel is badly pitted, you should consider getting it inspected to insure it will still hold up or support what ever it was installed to do. If you want a smooth finish, once the rust removal is done, you can fill in the dips and pock marks with an auto body filler (Bondo is one brand name)... It comes in 2 parts (the main filler and a hardener) that are mixed well and used to fill in the holes and divits with a plastic spreader.. Once hard (in a few minutes with most brands of filler), sanding with sandpaper and a sanding block will smooth out the finish very nicely. From there, the same primer mentioned above and paint will finish up your project... Hope this helps some... Good Luck!
- Q:What is the standard thickness of steel coils?
- The standard thickness of steel coils can vary depending on the specific application and industry. However, common thickness ranges for steel coils typically fall between 0.015 inches (0.38 mm) and 0.125 inches (3.17 mm).
