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 are steel coils processed for cutting to length or blanking?
- Steel coils are processed for cutting to length or blanking through a series of steps. First, the coil is uncoiled and flattened to remove any inherent deformities. Then, the edges are trimmed to ensure uniform width and straightness. Next, the coil is fed into a leveling machine to eliminate any remaining inconsistencies in thickness. Once leveled, the steel is conveyed to a cutting machine where it is precisely cut into individual sheets of desired length or blanks. These sheets or blanks are then stacked and prepared for further fabrication or distribution.
- Q:How are steel coils inspected for quality control purposes?
- Steel coils are inspected for quality control purposes through various methods such as visual inspection, dimensional checks, and non-destructive testing techniques. Visual inspection involves examining the surface of the coil for any defects or irregularities. Dimensional checks are conducted to ensure that the coil meets the specified thickness, width, and length requirements. Non-destructive testing techniques like ultrasonic testing or magnetic particle inspection are used to detect internal flaws or defects in the steel coil. These inspection methods help ensure that the steel coils meet the desired quality standards before they are used in various applications.
- Q:if steel is heated from room temperature (20c) to (500c) what would be the change in density?coefficient for linear expansion of steel 12x10^-6 k density of steel 7800 kg
- First you have to convert the coefficient of linear expansion to a coefficient of volumetric expansion. Multiply the coefficient of linear expansion by 3: Coefficient of expansion of steel,β:12E-6/°K x 3 = 36E-6/°K Difference in temperature: 480°K ΔV = VoβΔT ΔV = Vo x (0.000036) x 480 ΔV = 1m? x 0.017 ΔV = 0.017m? Originally, the steel was at 7800 kg/m? Now, the steel was at 7800 kg/ 1.017m?, or 7670 kg/m? Change in density = 7670 - 7800 = -130kg/m?
- Q:I'm looking for a good source as to the 'structural formula' of steel. I'm not quite sure if that's what it's actually called, but here's a link to what I'm looking for.
- That's a very good question. What you need to do is run down to your local university and sign up for a undergraduate degree in Civil Engineering and after you finish that (4 to 5 years) then you need to sign up for a masters degree in Structural Engineering (2 to 3 years). Then, get yourself a structural engineering job and in 4 years you will be able to test to become a Professional Engineer. Whew, after that you will get paid very well as a tower designer.
- Q:How do steel coil manufacturers ensure employee safety?
- Steel coil manufacturers ensure employee safety through a combination of safety training programs, implementation of safety procedures and protocols, regular equipment maintenance, and providing personal protective equipment. They also conduct regular safety audits and inspections to identify and address any potential hazards in the workplace.
- Q:and what are the four main elements in STAINLESS steel? x
- decreasing the carbon content fabric will strengthen the ductility, which will make it greater versatile. Carbon in metallic varieties brittle cementite (iron carbide) which will strengthen the hardness and capability of metallic.
- Q:Can steel coils be recoiled?
- Yes, steel coils can be recoiled. Recoiling involves rewinding a steel coil into a more compact shape, typically to improve storage or transportation efficiency. This process is commonly used in industries such as manufacturing, construction, and transportation.
- Q:How are steel coils used in the production of HVAC equipment?
- Steel coils are commonly used in the production of HVAC equipment as they serve as the primary component in heat exchangers. These coils are responsible for transferring heat between the refrigerant and the air, allowing the equipment to cool or heat the surrounding space effectively. The steel coils are designed to maximize surface area and optimize heat transfer, ensuring efficient and reliable operation of HVAC systems.
- Q:How are steel coils used in the production of wind turbines?
- Steel coils are used in the production of wind turbines to manufacture the tower, nacelle, and other structural components. The coils are processed and shaped to form the required sections, which are then assembled and integrated to create the framework and support structure for the wind turbine. The high strength and durability of steel make it an ideal material for withstanding the demanding conditions and loads experienced by wind turbines.
- Q:No. Not Stainless steel, I mean STEEL.Not a specific type, but STEEL.Thanks. xo
- Steel is mostly iron. However, it is an alloy or solid solution, or mixture of iron and other metals or sometimes carbon. All steel is a mixture. there are many varieties.
