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: Im getting a new guitar soon, and it has steel strings. ive heard that nilon strings are better? thanks:)
- Nylon is allegedly better for beginners because they don't cut into the fingers as much. Steel sounds much better, though.
- Q: I made a wood crossbow body but all I need is a bow which I want to be metal. I've used a thin steel sheet that I cut to appropriate size but when it bent with the string strung, it never went to original shape after being shot. I used a slightly thicker and it wouldn't bend at all. Anybody know what thickness and type to use? Any real answers are very appreciated. Thanks.
- You are trying to use plain carbon steel which only can be bent a little bit if it is to return to its original shape. You have to use spring steel or high carbon steel that is intended to be bent a lot and still recover to its original shape. Most people making crossbows with metal bows get a piece of steel from a leaf spring of a vehicle and grind it to shape. A steel bow cross bow almost always needs a very strong trigger mechanism and a miniature wench to pull the steel bow string into position. You might be better off making the bow of wood.
- Q: Can steel coils be coated with magnetically attractive materials?
- Yes, steel coils can be coated with magnetically attractive materials. This process is commonly known as electromagnetic coating or magnetic coating, where a thin layer of magnetically attractive material, such as iron or nickel, is applied onto the surface of the steel coil. This coating enhances the magnetic properties of the steel, making it more responsive to magnetic fields and enabling it to attract or be attracted by magnets.
- Q: What's the length of a coil of cold rolled steel? Is there a standard?
- In 2.0*1000*C calculations, it is assumed that the formula for the length of 5T in this volume is 5000/ (2.0*1000*1000*7.93) = the total number of meters. First, the weight of one meter is calculated by dividing the total weight by the single weight, that is, the theoretical length of the volume
- Q: i have noticed in guns, and artillery the shell casings are always made out of brass. brass is expensive, weaker and dosnt look as good as steel. so why use it for casings? i am aware some of the case must be deformed. but just a small brass percussion cap could be used just for that and steel for the rest. whats going on?
- Expansion and more resistant to rust. Besides, steel cased ammo is made in East Eur..abia in all kinds of calibers but many people complain about it not being able to expand or that the steel wears out the extractor faster (not true), then they go and buy some.
- Q: How are steel coils used in the production of rail tracks?
- Steel coils are used in the production of rail tracks as they are processed and shaped into long sections known as rails. These coils are first uncoiled and then heated, allowing them to be rolled and formed into the desired rail shape. The resulting rails are then cut to the required length and undergo further processes such as straightening and finishing to ensure their strength, durability, and suitability for use in railways.
- Q: What kind of insulation should be used in a steel building?
- Vinyl fiberglass insulation is getting popular with the steel building industry. The vinyl fiberglass insulation offers a shining look to the building and is resistant to dust as well as condensation. Effective ventilation inside the steel building can also help in preventing the condensation process inside the building. Besides, the building doors should be insulated effectively so as to minimize the heat loss. Be sure to seal all the door gaps in the building. All these steps are necessary to follow to get an effectively insulated steel building.
- Q: What is the role of steel coils in the automotive industry?
- Steel coils play a crucial role in the automotive industry as they are used to manufacture various components and parts of vehicles, including body panels, frames, chassis, and suspension systems. The high strength and durability of steel make it an ideal material for ensuring structural integrity and safety in automobiles. Additionally, steel coils offer cost-effectiveness, versatility, and the ability to withstand extreme conditions, making them an essential component in the production of cars and trucks.
- Q: Can steel coils be used in the production of automotive parts?
- Indeed, the utilization of steel coils is possible in the manufacturing of automotive parts. Various automotive components like body panels, frames, chassis, suspension parts, and engine parts frequently incorporate steel coils within their production process. To achieve the desired shape of these automotive parts, the steel coils typically undergo a range of techniques including cutting, stamping, bending, and welding. The strength, durability, and corrosion resistance of steel make it a favored material for automotive parts. Additionally, steel coils are accessible in different grades and thicknesses, enabling manufacturers to customize the material properties to fulfill specific requirements for diverse automotive applications. Collectively, steel coils play a crucial role in the fabrication of automotive parts, thereby contributing significantly to the performance, safety, and durability of vehicles.
