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:How long does the coating on steel coils last?
- The longevity of the coating on steel coils can vary depending on a variety of factors including the type of coating, environmental conditions, and usage. However, with proper maintenance and protection, a well-applied coating can typically last anywhere from 10 to 30 years.
- Q:How do steel coils contribute to the aerospace manufacturing industry?
- Steel coils are essential in the aerospace manufacturing industry as they are used to produce various components, such as aircraft bodies, wings, and landing gear. These coils provide the necessary strength, durability, and resistance to extreme conditions required for aerospace applications. Additionally, steel coils can be easily shaped and welded, enabling manufacturers to create complex and precise structures, thereby enhancing the safety and efficiency of aircraft.
- Q:What are the common methods of recoiling steel coils?
- The common methods of recoiling steel coils include slitting, rewinding, oscillating, and recoiling using a mandrel or a recoiler machine. Slitting involves cutting the wide coil into smaller widths, while rewinding involves rewinding the coil into a tighter, more compact roll. Oscillating is a method where the coil is wound back and forth to create a narrow, oscillating coil. Finally, recoiling using a mandrel or a recoiler machine involves winding the coil onto a mandrel or a spool to create a new coil of desired size and shape.
- Q:What are the different surface finishes available for steel coils?
- Some of the different surface finishes available for steel coils include hot-dip galvanized, galvannealed, electro-galvanized, and plain.
- Q:Can steel coils be rewound?
- Yes, steel coils can be rewound.
- Q:i recently got an industrial piercing and instead of getting pierced with a metal bar i have a PTFE bar .. i eventually want to put in a metal bar but what kind do i get? whats the difference between a surgical steel and titanium bar?thanks
- Titanium Industrial Bar
- Q:How are steel coils used in the production of HVAC equipment?
- Steel coils are used in the production of HVAC equipment primarily for their heat transfer capabilities. These coils, made of high-quality steel, are essential components in the heat exchangers of HVAC systems. They help facilitate the transfer of heat between the refrigerant and the surrounding air, allowing for efficient heating or cooling. The steel coils are typically designed with fins or tubes to increase the surface area and enhance heat transfer efficiency, ensuring optimal performance and energy efficiency in HVAC units.
- Q:How are steel coils used in the automotive stamping industry?
- Steel coils are used in the automotive stamping industry to provide a continuous supply of flat steel sheets that are then fed into stamping machines. These coils are unrolled, straightened, and then fed through the stamping presses to create various automotive parts, such as body panels, chassis components, and other structural parts. The use of steel coils ensures efficiency, precision, and a consistent quality in the production of automotive parts.
- Q:How are steel coils inspected for flatness variations?
- Steel coils are inspected for flatness variations using various methods such as visual inspection, measurement techniques, and automated systems. Visual inspection involves trained personnel visually inspecting the coil's surface for any irregularities or deviations from flatness. Measurement techniques involve using precision instruments such as straight edges, feeler gauges, or laser sensors to measure the flatness at different points along the coil's length. Automated systems use advanced technologies like laser scanning or optical sensors to quickly and accurately detect any flatness variations in the steel coils. These inspections help ensure that the coils meet the required flatness specifications and quality standards.
- Q:For example, (and this is weird) if I were wearing a steel collar and I needed some way to remove it, with limited supplies.Force is difficult because it would be around my neck.Chemical cominations are great- but they have to use VERY common products. And I'm not sure what to use.Other ideas?
- Your best bet would be a grinding wheel attached to a small electric motor. Even if you slipped, your skin is too soft to be cut by the dull wheel. Steel, however, is easily cut. But perhaps you don't have access to electricity or pressurized air to run such a tool. In that case, a simple file would work well, though you'd be somewhat more likely to injure yourself. If you had no tools, but access to whatever chemicals you wanted, you could try a weak acid. This would take a long time, and require constant scrubbing to bring fresh acid into the pits in the metal, but it would eventually eat through the collar.
