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.

- 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 cant find this stuff about steel:conductivitystrengthcorrosion resistancecommon applicationsif you know of any interesting facts, i could use those 2!thanx!
- The strength and corrosion resistance depends on the mix. Pure steel is pure iron plus 6% pure carbon. It is the carbon molecules that give it a tough crystallized strength. Pure iron is wrought iron and you can bend that with your hands. Strength also depends on the shape of the beam the most common steel beam is the W flange more commonly called the I beam. That is because the strength of the ‘I’ beam is just a little bit less than if the entire I beam was filled in; however the weight and material savings is huge. Steel itself has no corrosion resistance and is often given a zinc coating just to resist oxidization. Manganese, vanadium and tungsten are just some of the other elements added to improve the steel.
- Q: I heard about a new bike the specialized allez steel. Has anyone heard anything about it. it will have all brand new components like shimano 2300 parts and everything. it looks nice.
- Steel? I doubt it's made out of steel, more labor and a heavier frame. Most likely aluminum. Shimano 2300 you say? The Shimano 2300 is the lowest of the low of Shimano road components. Most likely not too reliable and heavy. www.cyclestore .uk/productDetai... I think this is what you might be looking for.
- Q: What is the process of pickling and oiling steel coils?
- To ensure the quality and protection of steel coils, a series of steps are undertaken in the process of pickling and oiling. The first step involves pickling, wherein impurities and scale are removed from the surface of the steel coil. This is achieved by immersing the coil in an acid bath, such as hydrochloric acid or sulfuric acid, which effectively dissolves any oxides, rust, or contaminants present on the surface. This step is critical as it readies the steel for further processing and safeguards against potential defects or corrosion. Following pickling, the steel coils are rinsed with water to eliminate any residual acid and then dried. Once they are clean and dry, a layer of oil is applied to provide temporary corrosion protection and lubrication during subsequent handling and transport. The oil coating acts as a barrier, preventing rusting or oxidation before the steel undergoes further processing or is utilized in various applications. The oiling process can be executed through various methods. One common approach is to apply the oil using a roller or brush, ensuring an even coating across the entire surface of the coil. Alternatively, the coils can be passed through a bath or spray chamber where the oil is administered. The choice of oil depends on the specific requirements of the steel and its intended use, with options ranging from mineral oil and synthetic oils to specialized rust-preventive coatings. Once the oiling process is complete, the steel coils are typically stacked, wrapped, or packaged for storage or transportation. It is crucial to handle the coils with care to avoid damaging the oil coating and compromising the corrosion protection it provides. Overall, the pickling and oiling of steel coils are indispensable steps in the steel manufacturing process. They ensure the quality, cleanliness, and protection of the steel, thereby prolonging its lifespan and enhancing its performance in various applications.
- Q: It seems that steel would be stonger and more stable than wood, fire resistant, and better for the environment, so why are most homes wood-framed rather than steel-framed?
- Basically, it's because wood was available first and wood is still the cheaper, more widely available material. Way back when man started building dwellings similar to what we have now, steel was not an option for the masses. The process probably hadn't even been invented or perfected yet, there was not the widespread transportation of goods that we have today either. Early shelters were not even put together with nails, they use wooden pegs because metal was so expensive and not widely available. I can't say that it would be better for the environment; it takes a tremendous amount of electricity to smelt and produce metals. And you have the emissions problems from the factories and the power generation. I'd have to do more research on that one. A managed timber stand actually reduces greenhouse gasses and every scrap of that tree can be used in one form or another. The only energy expenditures are moving the trees to the saw mill, cutting at the saw mill and transportation of the goods after that point. And that would be a lot less than the power required to make the same number of feet of steel products.
- Q: How are steel coils used in the automotive industry?
- Steel coils are used in the automotive industry to manufacture various components, such as body panels, frames, and suspension parts. These coils are transformed into flat sheets or molded into different shapes to meet the specific requirements of each component. The high strength and durability of steel make it an ideal material for ensuring safety and structural integrity in vehicles.
- Q: What are the dimensions of steel coils used in the metalworking tool industry?
- The dimensions of steel coils used in the metalworking tool industry vary depending on the specific requirements of the tool being manufactured. However, common dimensions for steel coils in this industry range from 0.5 to 3 millimeters in thickness and 1000 to 2000 millimeters in width.
- Q: How are steel coils used in the manufacturing of machinery?
- Steel coils are used in the manufacturing of machinery as they provide a reliable and durable material for various components and structures. These coils are often shaped, cut, and formed into desired parts such as gears, shafts, frames, and supports. The high strength and versatility of steel coils allow them to withstand heavy loads and harsh conditions, ensuring the machinery's efficiency and longevity.
- Q: What are the main factors that affect the strength of steel coils?
- The main factors that affect the strength of steel coils include the composition and quality of the steel used, the manufacturing process employed, the thickness and width of the coils, and the presence of any impurities or defects. Additionally, factors such as temperature, humidity, and storage conditions can also impact the strength of steel coils.
- Q: What are the challenges in coil leveling for high-strength steel?
- One of the main challenges in coil leveling for high-strength steel is the material's inherent strength and hardness. High-strength steel is designed to have superior mechanical properties, which can make it difficult to manipulate and flatten during the leveling process. The high tensile strength and increased yield strength of the steel can cause it to resist deformation, leading to springback or permanent deformation issues. Additionally, the increased hardness of the steel can put more strain on the leveling equipment, potentially leading to wear and tear. Proper equipment selection, precise control of leveling parameters, and advanced process monitoring techniques are required to overcome these challenges and achieve accurate and consistent coil leveling results for high-strength steel.
