Structure of Aluminum Zinc Rolled Coil

 Prepainted Aluminum Zinc Rolled Coil for construction

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:I expect that I will be questioned about my knowledge in methoding for steel castings, in a interview. I dont know about it. Can someone explain me in simple language and give me some links, like how I can explain methoding for steel castings.....key points...help please...so that i will pass the interview as if I have experience in methoding....thanks
It is very difficult to define Methoding of Steel castings by one sentence. Actually it encompasses the total casting process. Normally it would mean a) Pattern design i.e. what type of pattern it would be- wooden, metallic, split or full, loose or fitted on a match plate or any other, how will be the parting line. b) Design of the gating system. c) Design of risering i.e. numbers, size and location of risers. d) Design of molding process i.e. sand system to be used, mold box size. But to do justice to the above mentioned activities, you need to consider other parameters of the casting process such as chemical composition, solidification characteristics, pouring temperature, pouring time, knock out time etc. As I said Methoding of Steel castings means designing of the total casting process from inception to final product.
Q:I was wondering because i just watched an episode of build it bigger on the discovery channel about the uss George bush, and when they were discribing it they said it was 500 tons of steel and 47,000 tons of aluminum. this kinda struck me as odd because i thought that it was mostly made of steel. and i would think that even if it was mostly aluminum, that the hull would be steel. and i think the hull would weigh more than 500 tons.

Q:So I'm trying to decide which is better. I've always had aluminum on my 6 yr old tb gelding as I do hunters on him. He's never had steel on but I've recently moved and the shoer here is more expensive. So is aluminum really worth the extra cash to keep him light on his feet or is steel really not that much different?
It really depends on your horse. If you horse is a good mover, and average weight steel shoe shouldn't make much of a difference. If the horse is a mediocre mover, sometimes the added weight will make it move worse. You should also understand that one steel shoe is not like another steel shoe- they come in different widths of web and thickness of steel. Some horses that don't do well in regular shoes do better in a light rim shoe or training plate. Discuss your concerns with your farrier, but he/she doesn't have a crystal ball. You may just have to try steel for a cycle and see how your horse does. When I am shoeing a horse that needs lighter weight steel, I tend to use either St. Croix's Lite Rim shoe or steel Concord training plate, or Kerckaert's DR training plate or the Triumph Lite steel shoe. All of these shoes are light weight, have decent traction and good break over.
Q:What are the different types of steel coil leveling methods?
There are three main types of steel coil leveling methods: roller leveling, stretcher leveling, and temper leveling. Roller leveling involves passing the coil through a series of rollers to reduce its curvature and improve flatness. Stretcher leveling uses hydraulic or mechanical stretching to remove the coil's internal stresses and straighten it. Temper leveling, on the other hand, subjects the coil to a controlled heating and cooling process to achieve the desired flatness. Each method has its own advantages and is chosen based on the specific requirements of the steel coil.
Q:What are the different types of surface defects in steel coils?
Some common types of surface defects in steel coils include scratches, pits, rust, scaling, laminations, and waviness.
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 roofing panels?
Steel coils are a critical component in the production of metal roofing panels. These coils, which are rolled sheets of steel, play a crucial role in shaping and forming the panels. To start with, the steel coils are unwound and fed into a machine called a roll former. This machine uses a series of rollers and dies to gradually shape and bend the steel into the desired profile of the metal roofing panel. The coils pass through these rollers, which apply pressure and force to mold the steel into the required shape and size. Once the metal has been formed into panels, it may undergo additional processes to enhance its durability and appearance. This can include galvanizing or coating the panels with various protective layers to prevent corrosion and improve weather resistance. These additional steps help to ensure that the metal roofing panels are able to withstand harsh environmental conditions and provide long-lasting performance. Steel coils are preferred in the production of metal roofing panels due to their strength and durability. Steel is known for its exceptional strength-to-weight ratio, making it a suitable material for roofing applications. Additionally, steel is highly resistant to various weather conditions, including high winds, heavy rains, and extreme temperatures. This makes it an ideal choice for roofing panels that need to withstand the elements and provide reliable protection for buildings. Overall, steel coils are an essential component in the manufacturing process of metal roofing panels. They are used to shape and form the panels, which are then further processed to enhance their durability. The use of steel in these panels ensures that they can withstand harsh weather conditions and provide long-lasting performance for residential, commercial, and industrial buildings.
Q:What are the environmental considerations when using steel coils?
Some environmental considerations when using steel coils include the extraction and processing of raw materials, energy consumption during production, and the potential for air and water pollution. Additionally, the disposal of steel coils at the end of their life cycle should also be taken into account to minimize waste and promote recycling.
Q:What are the safety precautions when handling steel coils?
When handling steel coils, it is important to follow certain safety precautions. First, workers should wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and steel-toed boots to protect against cuts, impacts, and eye injuries. Additionally, workers should receive proper training on safe lifting techniques to prevent strains and back injuries. It is crucial to use appropriate lifting equipment such as cranes or forklifts to avoid manual handling injuries. Adequate clearance should be maintained between coils and other objects to prevent accidents or damage. Lastly, workers should be aware of the weight and dimensions of the coils to ensure they are properly secured during transportation and storage.
Q:What is the average shelf life of a steel coil?
The average shelf life of a steel coil can vary depending on various factors such as the type of steel, storage conditions, and handling practices. Generally, steel coils can be stored for several months to a few years without significant degradation in quality. However, it is important to ensure proper storage conditions, such as maintaining a dry and clean environment, protecting against moisture and corrosion, and avoiding excessive pressure or stacking. Regular inspection and maintenance can help to extend the shelf life of steel coils even further.
