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: Nickel is ferro magnetic in nature. But when it is added with stainless steel, it makes stainless steel non-magnetic. What is the structural changes happened with the presence of nickel?
- Steel is magnetic because of the alignment of the spin in the electrons of the atoms in the crystaline matrix of the steel. Nickel atoms are not the same size as Iron atoms and Chromium atoms. by having several different sizes of atoms in the alloy, it prevents a uniform crystaline matrix from being formed. If you imagine a box of marbles that are all the same size, they will all settle into a regular pattern in the box. But a bunch of mismatched marbles will be jumbled together in irregular patterns. This prevents the magnetic properties of either element from asserting itself.
- Q: What metals contain steel? It can be anything except soft iron or steel.
- tricky situation. look from google. it may help!
- Q: i mean cor ten steel( rusted)
- If the steel is true Cor Ten steel, it does not require waxing. Cor Ten is a steel designed to rust slowly over time ... then the rust acts as a natural barrier to prevent further rust. Check out the United States Steel building in downtown Pittsburgh, PA ... its nickname is The Rusty Nail.
- Q: You have two steel wool pads,one is cut up into little pieces, and the other is whole, and they are both submerged in water. 1.Which steel wool pad will rust quicker?2.How much faster will that pad rust? (estimate+explain the estimate)6.How could you make the steel wool pad rust faster?Please dont tell me to do my homework because I tried, but I bought the wrong type of steel wool
- steel wool = iron fibers and rusts easily in air iron + Oxygen BUT the blue soap protects the iron at first. that needs to be cleaned off. damp surfaces speed the rusting but compeletly underwater there is not much O2, ther eis some temperature has an effect. the rusting depends ofn the area of the fibers which does NOT change when you cut th epad in smaller pieces. a good beginners experiment In old times thye thought the rusted material would lose weight becasuse it was not solid iron any more careful experiments showed it gained weight and lead to and understanding of chemistry
- Q: Can steel coils be reused?
- Yes, steel coils can be reused. They are often recycled and repurposed for various applications in different industries.
- Q: How hot does steel have to get before it will melt?
- Type your query into Yahoo! Search or other search engines to get the answer: It depends, since steel usually has different metals added for various properties (strength, corrosive resistance, etc.)
- Q: Aluminum alloy rolling doors and color steel shutter door that good
- Hello, the shutter door material mainly galvanized steel plate, color steel plate, aluminum alloy, stainless steel, PVC soft board, PVC soft door curtain.
- Q: What are the different types of steel coil transport methods?
- There are several different types of steel coil transport methods, including trucking, rail transportation, and sea freight. Trucking involves using flatbed trucks or specialized trailers to transport steel coils over short distances. Rail transportation utilizes flatcars or specialized railcars to transport steel coils over long distances. Sea freight involves shipping steel coils in containers or on specialized vessels across international waters.
- Q: How do steel coils contribute to energy performance in buildings?
- Steel coils contribute to energy performance in buildings through their use in the construction of energy-efficient heating, ventilation, and air conditioning (HVAC) systems. Steel coils are commonly used in HVAC equipment, such as air handlers and heat exchangers, due to their excellent thermal conductivity and durability. By efficiently transferring heat or cool air, steel coils help regulate the temperature in buildings, reducing energy consumption and improving overall energy performance. Additionally, steel coils are often used in the construction of insulated panels and roofing systems, providing excellent insulation and preventing thermal bridging, thereby further enhancing the energy efficiency of buildings.
- Q: I know that the steel is significantly harder than when air cooled, but why is the quenched steel harder?
- When steel is slowly cooled, lots of carbon diffusion takes place because it is not very soluble in steel at room temperature. The carbon is in solution at high temperatures, and is rejected out of the lattice as it cools. And when this happens, the microstructure will consist of ferrite and pearlite, and the lattice structure will be base centered cubic (bcc). If it is cooled fast enough, then the carbon gets trapped in the interstitial sites of the lattice and distorts it to a body centered tetragonal (same as bcc, but elongated in one direction) This elongation strains the lattice and makes it harder. Also, when cooled fast enough the atoms do not have time to diffuse like they normally would and they shear into place. This forms the hard phase of martensite that is desired of heat treated steel. But then it must be tempered back some because it is too brittle.
