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 they worth today? As well as a 1943 steel nickel?
- The article I am inclosing quotes the price at 50 cents, apparently the 1943 copper penny is worth thousands of dollars.
- Q: explain what happen if carbon steel is exposed to an oxygen rich atmosphere at elevated temperature inside a furnace.
- Blowing oxygen or air rich in oxygen through molten carbon steel is a way of lowering the carbon content. The properties of carbon steel depend very much on the carbon content . too much and it is very brittle. It is all governed by a complex phase diagram. If the steel isn't actually melted, then only insignificant effects at the surface will occur.
- Q: How are steel coils tested for quality?
- Steel coils are tested for quality through a series of rigorous inspections and tests. These include visual inspections to identify any surface defects, dimensional measurements to ensure proper size and shape, and mechanical tests such as tensile strength and hardness tests. Additionally, non-destructive testing methods like ultrasonic testing and magnetic particle inspection are used to detect internal defects or cracks. These comprehensive quality checks ensure that steel coils meet the required standards and are fit for their intended applications.
- Q: What is the difference between steel coils and steel sheets?
- Steel coils and steel sheets differ primarily in their form and dimensions. Steel coils are long, continuous rolls of steel that have been wound up after being processed. They are typically produced in large quantities and are used in various industries, such as automotive and construction. Steel sheets, on the other hand, are flat pieces of steel that have been cut from coils or directly produced in a flat form. They come in different sizes and thicknesses, making them more suitable for specific applications such as roofing, cladding, or fabrication. In summary, while steel coils are the raw material for steel sheets, the main distinction is that coils are long rolls, while sheets are flat pieces of steel.
- Q: What are the different steel coil specifications?
- There are several different steel coil specifications available, including dimensions, thickness, width, and weight. These specifications vary depending on the specific application and industry requirements. Additionally, steel coils can be classified based on their surface finish, such as hot-rolled, cold-rolled, or galvanized.
- Q: I have hundreds of pounds of scrap steel... who purchases this steel and what is the price per pound etc. of this? Does someone pick it up or do I bring it somewhere?
- It okorder /
- Q: What are the different thickness tolerances for steel coils?
- The different thickness tolerances for steel coils can vary depending on the specific grade and type of steel being used, as well as the industry standards and customer requirements. However, common thickness tolerances for steel coils typically range from +/- 0.005 inches to +/- 0.020 inches, with tighter tolerances available for certain applications.
- Q: How are steel coils used in the manufacturing of pipes and tubes?
- Steel coils are used in the manufacturing of pipes and tubes by being formed and shaped into the desired dimensions and then welded or seamless to create the final product. The coils provide a continuous and consistent source of steel material, ensuring high-quality and reliable pipes and tubes.
- Q: Does the solution change, or does only the steel wool change color?
- once you upload water to anhydrous copper(II) sulphate it turns blue because of the fact that's going to become hydrous copper(II) sulphate. Then, in case you upload water greater, that's going to proceed to be blue, could be slightly darker.
- Q: I know that mild steel is more brittle than cast iron....but that is all.......please help??Thank you in advance......Ruby:D
- Actually, the opposite is true. CAST IRON is generally brittle, while mild steel is not. Cast iron has a carbon content from about 2%-4%. Mild steel has less than one tenth as much carbon as cast iron- around 0.2% - 0.3%. Cast iron also typically has from 1%-3% silicon. Most mild steel contains no more than 0.3% silicon. Steel melts at ~1450 degrees C. The addition of large amounts of carbon and silicon to C.I. lower the melting point to around 1200 C and make it more fluid than molten steel. Obviously this makes it easier to melt and to pour. The main advantage of cast iron is it's cheap to produce. It also has some desirable properties despite it's brittleness. For example it's easy to cut and carve with machine tools. It's also very heat resistant and excellent at absorbing vibration. For this reason C.I. was commonly used for engine blocks and exhaust manifolds in cars and trucks in the past, (Cast aluminum engine blocks are more common these days because Al is much lighter and conducts heat better.) Cast iron also rusts much more slowly than steel which is why it's still commonly used for pipes. C.I. pipes have been known to last 300 years.
