Structure of Aluminum Zinc Rolled Coil
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.
Applications of Aluminum Zinc Rolled Coil for Construction Roof
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: What are the different surface treatments applied to steel coils?
- Some different surface treatments applied to steel coils include galvanizing, electroplating, painting, and powder coating. These treatments help to protect the steel from corrosion, improve its appearance, and enhance its durability for various applications.
- Q: I went to the store to get metal to make a knife and they had weldable steel and plate steel. Which one would be best/ which steels would be best for what i want to do?
- 'Plate' does not refer to a specific alloy. It simply describes the shape in which the metal is sold. Various steel alloys have varying degrees of weldability. Some weld well, with good strength. Others weld poorly, and crack or become very weak. Try looking up information on the specific alloy of steel.
- Q: How are steel coils processed for edge trimming or conditioning?
- Steel coils are processed for edge trimming or conditioning through a series of steps. First, the steel coils are unwound and fed into a machine that trims the edges to remove any irregularities or imperfections. This process helps ensure that the edges of the steel coils are straight and smooth. After edge trimming, the coils may undergo further conditioning processes such as leveling, slitting, or recoiling, depending on the specific requirements of the end product. These processes help to refine the steel coils and prepare them for various applications in industries such as automotive, construction, or manufacturing.
- Q: How are steel coils processed before they are used in manufacturing?
- Steel coils undergo several processing steps before they are used in manufacturing. The first step is called pickling, where the coils are immersed in an acid bath to remove any surface impurities, such as rust or scale. This helps to improve the surface quality of the steel. After pickling, the coils go through a process called cold rolling. This involves passing the coils through a series of rollers to reduce their thickness and improve their dimensional accuracy. Cold rolling also enhances the mechanical properties of the steel, making it stronger and more durable. Next, the coils are annealed, which involves heating them to a specific temperature and then slowly cooling them. Annealing helps to relieve internal stresses in the steel and improves its formability and ductility. Following the annealing process, the coils may undergo additional surface treatments, such as galvanizing or coating. Galvanizing involves applying a layer of zinc to protect the steel from corrosion, while coating can involve applying various types of paint or polymer to enhance the steel's appearance or provide specific functionalities. Once the coils have been processed and treated, they are typically cut into smaller sheets or strips, depending on the manufacturing requirements. These sheets or strips can then be used in various manufacturing processes, such as stamping, forming, welding, or fabrication, to create a wide range of products, including automotive components, appliances, construction materials, and many others. In conclusion, steel coils undergo a series of processing steps, including pickling, cold rolling, annealing, and surface treatments, before they are ready to be used in manufacturing. These processes improve the quality, strength, and formability of the steel, allowing it to be transformed into a variety of products.
- Q: My 8-year-old and 9-year-old boys have approached me with an interesting question. Does fire burn steel? One says yes, the other says no. Help me to settle yet another debate :)
- no, fire MIGHT cause steel to oxidize, depending on the alloy, but think of steel as a block of ice. Steel melts at 2800 degrees F and boils and evaporates at 5400 degrees. Some metals like magnesium can possibly catch fire but not steel
- Q: What's the length of a coil of cold rolled steel? Is there a standard?
- Generally, according to the volume measurement, each roll weighs 3~15 tons.
- Q: I have a Charles Daly shotgun and I'm trying to find out if it is ok to shoot steel out of. The side engravings say: Charles Daly 20 GA 3 and the other side says : KBI-HBG, PA made in TurkeyOn their website it says that the barrel on the Charles Daly 300 Field is able to shoot steel but I don't see anywhere that this is a 300 model.Im also not sure if the choke is able to shoot steel. It has no engravings on it. How can I tell if this choke will work? It is the original choke that came with the gun?
- Kbi Shotguns
- Q: What is the difference between a steel strip and a coil? The steel strip is flat steel, and the steel coil is made of steel. Is that correct?
- A steel strip is also a coil, usually a narrow strip, also known as a steel strip. The volume is relatively wide. In addition, flat steel is usually hot-rolled out of long strip steel, fixed length 5 and 5.5,6 meters range, steel coil is Kaiping Chang 12501500, length 2.5 meters, 4 meters, 6 meters, ranging from steel plate
- Q: So carbon is gas that brakes down to hydrogen and helium before going in...And steel can go a little farther towards sun before evaporating.. 200 degrees closer at leastso steel is full of a heavier gas bomb in my hypothesis and needs to be broken up outside stars(broken down)Is steel capable of going into sun with an element thats wrong wayLike iron has no air to boil outAnd steel goes just as far with carbon in it..Other words can u answer me with..Carbon is already IN the sun and is capable of braking down Carbon INSIDE the star/sunOnly way I see steel boiling is inside and it releases carbon gas at once..carbon bomb
- Carbon is an element, which is your first oversight. The rest of you statements are not clearly presented. Let alone make any sort of sense.
- Q: I am building a robot for Bots IQ. In doing so i have the option of building the the armor of my robot out of titanium or tool steel.. which would be the better option.Brief description of Bots IQ: It is a competition where 2 15lb robots go and attack each other with spinning blades, hammers or whatever is designed.
- Titanium is a significantly stronger and lighter metal, but is also extremely expensive. If you have the option for titanium, go for it.
