Description of Prepainted Galvalume Rolled Coil
Aluminum zinc coils 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 Galvalume Rolled Coil
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 Galvalume Rolled Coil
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: rust is not a issue. i was looking a D2 steel but heard story's of it chipping and breaking
- Ok, lets define what is Damascus steel. The modern Damascus is basically any steel that shows a pattern. Patterns are accomplished by 1. manipulating the crystal structure or 2. by combining 2 or more different alloys together. The blade you are looking at is referred to as a pattern welded blade. Damascus is only as strong as it's base components + heat treat and design. The strongest will be obtained by combining high carbon and low carbon steels. I do this by using steel cable. The patterns aren't real bold but are interesting none the less. To break it you must brake the hard steel and tear through the soft iron. The laminated stuff works the same way. For greater edge holding I use all high carbon, varying alloy content from simple carbon to chromium/nickle alloys. These are what you normally find in pattern welded blades. A fine pattern that has many lamination's crossing the edge will offer the best edge holding. Properly done one can get the DCE or damascus cutting effect where the soft layers wear away faster than the hard layers almost making the blade self sharpening. Is that blade good? Buy it if you like it, it won't compare to a well made hand forged blade but is much cheaper. sorry for the overload.
- Q: How are steel coils used in the shipbuilding industry?
- Steel coils are used in the shipbuilding industry primarily for the construction of ship hulls, decks, and other structural components. These coils are typically processed and shaped into plates, beams, and other forms to provide strength and stability to the ship's structure. The high tensile strength and durability of steel make it an ideal material for shipbuilding, ensuring the vessel's ability to withstand harsh marine environments and heavy loads.
- Q: How do steel coils contribute to the automotive manufacturing sector?
- Steel coils are essential in the automotive manufacturing sector as they are used to produce various components such as body parts, frames, and suspension systems. The high strength and durability of steel coils make them ideal for ensuring the safety and structural integrity of vehicles. Additionally, steel coils are easily moldable, allowing manufacturers to create complex shapes and designs, contributing to the overall aesthetics and functionality of automobiles.
- Q: How are steel coils used in the manufacturing of electrical wiring?
- Steel coils are used in the manufacturing of electrical wiring as a core material for cable reinforcement. The coils provide structural strength and support to the wires, ensuring durability and resistance to external forces. Additionally, the steel coils help in maintaining proper electrical conductivity and minimize electrical losses, ensuring efficient power transmission and distribution.
- Q: Is Stainless steel called that because.....a. Its stains lessORb. Its virtually stainless (it can't stain).Lol do you know the correct answer?????
- a. is the correct answer. It will still show tea and coffee stains. I find using baking soda is a good way to clean it and freshens the drains of the sinks as well. If cleaning your refrigerator a glass cleaning spray works well, just be sure to dry it thoroughly.
- Q: How are steel coils used in the manufacturing of storage racks?
- Steel coils are used in the manufacturing of storage racks by being cut into smaller, more manageable pieces that are then shaped and welded into the desired rack structure. The strength and durability of the steel coils make them an ideal material for supporting heavy loads and ensuring the stability of the storage racks.
- Q: How are steel coils used in the manufacturing of industrial equipment?
- Steel coils are used in the manufacturing of industrial equipment as they serve as a primary raw material for fabricating various components such as frames, supports, and structural elements. These coils are often cut, shaped, and welded to create the desired parts and structures that provide strength, durability, and stability to the equipment. The steel coils ensure that the industrial equipment can withstand heavy loads, resist corrosion, and maintain structural integrity, making them vital in the manufacturing process.
- Q: What are the common coil sizes available for steel coils?
- The steel coil sizes available for different industries and applications vary. However, there are standard sizes commonly used across sectors. These sizes include coil widths of 36 inches, 48 inches, 60 inches, and 72 inches. In terms of coil diameter, the most common sizes range from 20 inches to 24 inches. Furthermore, coil weights can vary greatly depending on the type of steel and its intended use, ranging from a few thousand pounds to tens of thousands of pounds. It is important to note that these sizes can differ among steel manufacturers, so it is advisable to consult the specific supplier or industry standards to determine the available coil sizes for a particular steel product.
- Q: Bronze came before steel, right? thanks
- Bronze The earliest surviving iron artifacts, from the 5th millennium BC in Iran and 2nd millennium BC in China, were made from meteoric iron-nickel. By the end of the 2nd millennium BC iron was being produced from iron ores from South of the Saharan Africa to China. Steel (with a smaller carbon content than pig iron but more than wrought iron) was first produced in antiquity. New methods of producing it by carburizing bars of iron in the cementation process were devised in the 17th century. In the Industrial Revolution, new methods of producing bar iron without charcoal were devised and these were later applied to produce steel. In the late 1850s, Henry Bessemer invented a new steelmaking process, involving blowing air through molten pig iron, to produce mild steel. This and other 19th century and later processes have led to wrought iron no longer being produced. The earliest tin-alloy bronzes date to the late 4th millennium BC in Susa (Iran) and some ancient sites in China, Luristan (Iran) and Mesopotamia (Iraq).
- Q: What are the common methods of welding steel coils?
- The common methods of welding steel coils include arc welding, resistance welding, and laser welding.
