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:How are steel coils used in the manufacturing of airbags?
Steel coils are used in the manufacturing of airbags to provide structural support and stability. These coils are typically incorporated into the airbag module, helping to maintain its shape and ensure proper deployment in the event of a collision.
Q:How are steel coils used in the production of rail tracks?
Steel coils are used in the production of rail tracks as they are a primary raw material for manufacturing the rails. These coils are first processed to form the desired shape and dimensions of the rail tracks, which are then cut, welded, and shaped to create the individual rail sections. The steel coils provide the strength, durability, and flexibility necessary for the tracks to withstand heavy loads, extreme weather conditions, and constant use.
Q:Can steel coils be used in electrical applications?
Certainly, electrical applications can make use of steel coils. In the realm of electrical circuits, steel coils often serve as magnetic cores in transformers and inductors, which are indispensable components. The steel employed in these coils typically consists of high-quality electrical steel, possessing distinct magnetic attributes, including low core losses and high permeability. These attributes empower the steel coils to efficiently transmit electrical energy between various circuit components. Furthermore, steel coils can also find utility in other electrical applications, such as the construction of electric motors and generators. Taking everything into account, steel coils are extensively employed in electrical applications due to their magnetic properties and their capacity to handle high currents and temperatures.
Q:What are the different types of steel coil loading and unloading methods used during processing?
Some of the different types of steel coil loading and unloading methods used during processing include overhead cranes, forklifts, coil cars, and coil transfer systems.
Q:How are steel coils packaged for shipment?
Steel coils are typically packaged for shipment by being tightly wound and secured with steel bands or straps. They are often placed on wooden skids or pallets to provide stability and protection during transportation. Additionally, protective covers or sheets may be used to shield the coils from moisture and other potential damages.
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:What are the common coil handling equipment used in the industry?
Some common coil handling equipment used in the industry are coil cradles, coil reels, coil straighteners, coil feeders, and coil transfer cars. These tools are essential for safe and efficient handling of coiled materials during various manufacturing processes.
Q:I'm looking for the weight of different types of steel and haven't found anything helpful!!thank you
