Description of Aluminum Zinc Rolled Coil
The detailed information for the Al-Zinc coated steel coil is as following and it is mainly using for roofing producing, making ceiling grid and all kinds of roll forming structure.
Thickness: 0.20mm to 1.20mm
Width: 914mm, 1000mm, 1200mm, 1219mm and 1250mm, or slit narrow strip according to customer request, can be slit from 20mm to 610mm.
Coil ID: 508mm
Coil weight: 3 tons to 6 tons
Thickness tolerance: +/- 0.02mm or according to customer request.
Main Feature of Al-Zinc coated steel coil
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 Al-Zinc coated steel coil
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:Can steel coils be customized in terms of size and shape?
- Yes, steel coils can be customized in terms of size and shape.
- Q:How are steel coils used in the manufacturing of lighting fixtures?
- Steel coils are used in the manufacturing of lighting fixtures primarily for their structural strength and durability. The steel coils are shaped and formed into various components such as brackets, frames, and housings that provide stability and support for the lighting fixtures. Additionally, the steel coils are often coated or plated to enhance their aesthetic appeal and protect against corrosion.
- Q:will peircers use surgical steel? how do you know for sure what they are using?
- Most reputable piercers will use surgical steel. You can ask them beforehand and they will let you know what it is they are piercing you with. You can go out and buy a ring of your own and have them sterilize and use that to Peirce you with. Like I said though, most places do use surgical steel. I wouldn't worry too much. :) Just make sure you ask to be sure. Good luck!
- Q:What are the dimensions of steel coils used in the storage tank industry?
- Steel coils used in the storage tank industry come in various dimensions, depending on the specific requirements of the tank being manufactured. Generally, these coils are available in different sizes and thicknesses. The width of the steel coils can range from approximately 600 millimeters to 2,400 millimeters. Similarly, the length can vary from a few meters to tens of meters. The thickness of the coils can also differ, typically ranging from 1.5 millimeters to 10 millimeters or more. Factors such as the size and capacity of the storage tank, the material being stored, and the structural requirements of the tank determine these dimensions. Consequently, the tank manufacturer or designer would determine the specific dimensions for a given storage tank project, following industry standards and project specifications.
- Q:How do steel coils impact the environment?
- Steel coils can have both positive and negative impacts on the environment. On one hand, the production of steel coils requires significant amounts of energy and emits greenhouse gases, contributing to climate change. Additionally, the extraction of raw materials for steel production can lead to deforestation and habitat destruction. On the other hand, steel is highly recyclable, reducing the need for new steel production and saving energy and resources. Proper waste management and recycling practices can mitigate the negative environmental impacts of steel coils.
- Q:What are the common problems faced during steel coil production?
- Some common problems faced during steel coil production include surface defects such as scratches or dents, dimensional inconsistencies, coil breakage, edge wave formation, and coil slitting issues. Other challenges may include coil corrosion, improper coil cooling, and quality control issues.
- Q:What are the different finishes available for steel coils?
- There are several different finishes available for steel coils, including hot rolled, cold rolled, galvanized, and coated finishes.
- Q:I know that the steel is significantly harder than when air cooled, but why is the quenched steel harder?
- When steel is slowly cooled, lots of carbon diffusion takes place because it is not very soluble in steel at room temperature. The carbon is in solution at high temperatures, and is rejected out of the lattice as it cools. And when this happens, the microstructure will consist of ferrite and pearlite, and the lattice structure will be base centered cubic (bcc). If it is cooled fast enough, then the carbon gets trapped in the interstitial sites of the lattice and distorts it to a body centered tetragonal (same as bcc, but elongated in one direction) This elongation strains the lattice and makes it harder. Also, when cooled fast enough the atoms do not have time to diffuse like they normally would and they shear into place. This forms the hard phase of martensite that is desired of heat treated steel. But then it must be tempered back some because it is too brittle.
- Q:What are the common uses of stainless steel coils?
- Stainless steel coils are commonly used in a variety of industries for applications such as manufacturing automotive parts, appliances, construction materials, and HVAC systems. They are also utilized in the production of kitchen utensils, medical equipment, and food processing machinery due to their corrosion resistance, durability, and heat resistance properties.
- Q:hello, just wondering if there is such a thing as a stainless steel coating for my aluminum muffler prior to installation. Yes, i suppose you can say that im cutting corners, but my current finances wont allow me to pay full price for a stainless steel one, thnx
- No, cheap parts or expensive parts are your choices. The cheap ones...you hope they last long enough for you to get a new car before they wear out.
