Structure of Aluminum Zinc Rolled Coil

 Prepainted Aluminum Zinc rolled Coil for Construction roof

Description of Aluminum Zinc 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 Aluminum Zinc Rolled Coil for Construction Roof

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: Which is more reactive? Zinc or Steel? And why?
Zinc. Steel is an alloy consisting mostly out of iron, In the reactivity seris, zinc is more reactive than iron. Therefore, zinc is more reactive than steel
Q: How are steel coils used in the aerospace industry?
Steel coils are used in the aerospace industry for various applications including manufacturing aircraft components, structural supports, and engine parts. The coils are typically processed and shaped into specific forms such as sheets or plates, which are then used to construct critical components of aircrafts, ensuring strength, durability, and performance.
Q: A friends of mine says he has balls of steel and i told him i would melt em off with lava. He said it wouldnt work. i disagree
some lava is hot enough to melt steel. Mostly, though, the metal would react with the lava and get eaten up that way rather than directly melting. Most lava can contain an awful lot of iron and other metals without any difficulty and are rarely saturated with those metals.
Q: I want to experiment with making steel and want to especially make it stronger. And also I want to know if its possible to turn a meteorite into steel?
If you really want to do this, you should be getting some books on steel metallurgy rather than asking on Yahoo. ASM sells a Metallurgy for the non-metallurgist that would be a good introduction. Most university libraries will have the full ASM handbook that includes detailed information for different grades of steel (vol 1), heat treatment and surface hardening (vol 4), testing (vols 8-12), and casting (vol 15). A reference for continuous cooling transformation diagrams will also help in designing a heat treatment process. If you want to make something stronger than most commercial steels, you'll need to get into nanotechnology and unconventional steel processing methods like powder metallurgy. You can increase the strength of steel by about 1000% by reducing the grain size from 50 micron (typical for conventional processing methods) to 100 nm (achievable through high-energy ball milling). Though you'd also need to customize the chemistry to stabilize the grain size during the necessary thermal processing, I believe zirconium works well with iron.
Q: How are steel coils used in the production of oil and gas pipelines?
Steel coils are used in the production of oil and gas pipelines as they are formed into pipes and provide the necessary strength and durability required for transporting these resources over long distances. The coils are uncoiled and then shaped into pipes through a process called pipe forming or rolling, which allows for the creation of seamless or welded pipes depending on the specific requirements. These pipes are then further processed, such as being welded together, coated, or threaded, to ensure their suitability for the transmission of oil and gas. Overall, steel coils play a crucial role in the manufacturing of pipelines by providing the necessary raw material for their construction.
Q: What are the different methods of coil recoiling for steel coils?
Steel coils can undergo coil recoiling using various methods, each with its own advantages and applications. Some commonly used methods include: 1. Slitting and rewinding: This method entails cutting the wide steel coil into narrower strips, which are then rewound into smaller coils. Circular blade slitting machines are typically employed for steel cutting, while the rewinding process ensures tight and uniform winding of the narrower strips. Industries like automotive, construction, and packaging widely employ this method. 2. Rewinding with tension control: This method involves unwinding and rewinding the steel coil using tension control systems. These systems maintain consistent tension throughout the recoiling process, resulting in uniform winding quality. This method proves beneficial when handling delicate or sensitive materials that require gentle treatment. 3. Recoiling with edge trimming: In situations where steel coil edges are damaged, uneven, or flawed, edge trimming can be combined with the recoiling process. Edge trimming machines remove defective sections, ensuring coils with smooth and even edges. 4. Recoiling with surface treatment: Steel coils often undergo surface treatment processes like oiling, coating, or galvanizing to enhance corrosion resistance or improve surface properties. Recoiling can be performed alongside these treatments, guaranteeing proper application and uniform coverage across the entire coil surface. 5. Recoiling with tension leveling: Tension leveling is a process that eliminates coil shape defects, such as coil set or crossbow, by applying tension during recoiling. This method ensures a flat and even coil shape, which is advantageous for subsequent processing and manufacturing operations. 6. Recoiling with precision slitting: Precision slitting is a specialized method used to achieve extremely narrow strip widths or tight tolerances in the steel coil. It involves precise control of slitting knives and winding tension to ensure accurate and consistent strip dimensions. Industries requiring high precision, such as electronics or precision engineering, commonly employ this method. In summary, the choice of coil recoiling method depends on factors such as desired coil dimensions, material characteristics, surface requirements, and the specific industry or application. Manufacturers often combine multiple methods to meet the diverse needs of their customers.
Q: I have to explain some functions of stainless steel but after days of searching I cant find an answer. Thankyou in advance for your help :)
IT doesn't rust.
Q: How are steel coils used in the manufacturing of springs?
Steel coils are used in the manufacturing of springs by being compressed or wound into a helical shape, which provides the necessary flexibility and resistance to support various applications.
Q: what is the refining process doing to raw materials in steel
Refining process for steel include burning out the extra carbon and impurities with oxygen lancing and protecting the steel from atmospheric gas inclusion by protective environment during such process . Measured % of ferralloys are also added to produce various grades of steel . These may be done in induction furnace/ laddle refining furnace / crucibles converters etc.
Q: Why are steel saucepans and tea kettles covered with copper on the outside and the bottom? what r the goals of having high-quality pans that are thick and tea kettles that are thin walled?
Stainless steel is less conductive than copper. However, steel will retain heat longer and thus be distributed more evenly. (hence the thick bottoms, but also for balance). Copper on tea kettles is ideal to bring water up to a boil rapidly but since your not really cooking food, temperature distribution or control doesn't really matter. Now if your cooking sensitive food, then it does matter. For example, the use of a double boiler is preferred for chocolates. Temperature and distribution is critical. As far as relatively inexpensive copper clad pots and pans such as Revereware? Well, I don't see a difference but perhaps they did some testing.
