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: What is the process of slitting steel coils into narrower strips?
The process of slitting steel coils into narrower strips involves unwinding the steel coil, passing it through a set of rotating circular blades called slitters, and then rewinding the resulting narrower strips onto separate spools.
Q: Are steel coils used in the packaging industry?
Yes, steel coils are commonly used in the packaging industry for various applications such as securing and protecting products during transportation and storage. The strong and durable nature of steel coils makes them ideal for packaging heavy or bulky items, providing stability and preventing damage.
Q: I'm looking for the weight of different types of steel and haven't found anything helpful!!thank you
Just know the type of steel ,its density. Density gives you weight per unit of volume. For example: The density of mild steel is approximately 7.85 g/cm^3 (0.284 lb/in^3) From above , you can say that 1 cm^3 of volume of mild steel have 7.85 gram weight.
Q: for instance Cr-Ni steeldoes this refer to plated steel or a uniform mixture
stainless steel is an alloy normally iron with additions of C, Mn, Ni, Cr, and Nb - amounts added depend on properties required. Corrosion resistance is due to a very thin but dense layer of chromium oxide which forms at the surface and prevents further attack. Ordinary steel on the other hand becomes coated with a porous layer of iron oxide(rust) through which the atmosphere can pass and cause further corrosion.
Q: How are steel coils used in the manufacturing of automotive fenders?
Steel coils are used in the manufacturing of automotive fenders by being shaped and formed into the desired fender design. The coils are cut and stamped into specific shapes, then undergo a series of bending, welding, and finishing processes to create the final fender product. The strength and durability of steel make it an ideal material for fenders, providing protection to the vehicle's wheels and body in case of collisions or impacts.
Q: What is the process of galvanizing steel coils?
The process of galvanizing steel coils involves several steps to enhance their durability and protect them from corrosion. Firstly, the steel coils are cleaned thoroughly to remove any dirt, oil, or other impurities that may be present on the surface. This is done through an acid pickling process, where the coils are immersed in a bath of diluted acid solution or treated with a chemical cleaner. This step ensures that the surface of the coils is free from any contaminants, allowing for better adhesion of the zinc coating. After the cleaning process, the coils are rinsed to remove any remaining acid or cleaner. This is crucial to prevent any adverse reactions with the next step of the process. The next step is the actual galvanization, where the cleaned coils are dipped into a bath of molten zinc. The coils are carefully passed through the zinc bath using rollers or other mechanisms to ensure that the entire surface is coated evenly. The zinc bath is maintained at a specific temperature, typically around 450°C (842°F), which allows the molten zinc to bond with the steel surface. As the coils are withdrawn from the zinc bath, excess zinc is removed by passing them through air knives or by centrifugal spinning. This helps to control the thickness of the zinc coating and ensure a uniform appearance. Once the galvanization process is complete, the steel coils are cooled down gradually to room temperature. This allows the zinc coating to solidify and bond firmly with the steel surface, creating a protective barrier against corrosion. The final step in the process is inspection and quality control. The galvanized steel coils are inspected for any defects, such as uneven coating or areas with insufficient zinc coverage. This is usually done visually or through specialized equipment that can detect any anomalies. Additionally, the coating thickness is measured to ensure it meets the required specifications. Overall, the process of galvanizing steel coils is designed to enhance their longevity and protect them from rust and corrosion. By applying a layer of zinc coating to the steel surface, the coils become more resistant to environmental factors, making them suitable for a wide range of applications in various industries.
Q: Hi! does anyone know where can i find a building with a structure of steel frames, i need to do an analysis for school so i need joint details, girder details and such! PLEASE help me! thanks
if u need to analyse a steel framed structure for joint details the best example would be of a mechanic workshop...the truss of such a workshop is always supported on a portal frame and in most of the case thats a steel structure...do keenly observe the joints at the footing plates that is connected to the girder section...nd also observe the joints in truss of such a frame....myslf m a civil engg. student.
Q: I have a set of Stainless steel pots and pans. Everything is sticks to them. What must I do so things don't stick?
First, they must be absolutely shiny, clean. Use a scouring pad in circular motions to make them as smooth as possible, then use Non-stick spray, but read the label, some oil sprays contain water and they will stick every time. Spray with canola or pour canola in the pan and warm it up before putting in the food. For flavor you can mix the canola with some olive oil or butter, but don't overheat or they will smoke and burn. For frying pancakes or eggs, the best choice is a teflon coated pan, use an oil spray and medium heat only.
Q: What are the different types of steel coil surface treatments for durability?
There are several types of steel coil surface treatments used to enhance durability. These include hot-dip galvanizing, electro-galvanizing, galvannealing, and organic coating. Hot-dip galvanizing involves immersing the steel coil in a bath of molten zinc to create a protective zinc coating. Electro-galvanizing is a similar process, but it uses an electric current to deposit a layer of zinc onto the steel surface. Galvannealing combines the galvanizing and annealing processes to create a zinc-iron alloy coating that offers enhanced corrosion resistance. Organic coating involves applying a layer of paint or other organic material to the steel surface, providing protection against corrosion and enhancing aesthetics.
Q: How are steel coils used in the production of metal buildings?
Steel coils are an essential component in the production of metal buildings as they are used to create the structural framework and outer cladding. These coils are unrolled and cut into sheets, which are then shaped and formed into various building components such as beams, columns, and panels. The strength and durability of steel make it an ideal material for constructing metal buildings, ensuring they are capable of withstanding harsh weather conditions and providing long-lasting structures.
