Structure of Al-Zinc coated steel coil
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

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:What are the different coil leveling line configurations used for steel coils?
- The steel industry utilizes various coil leveling line configurations to meet specific requirements and preferences. Some commonly employed configurations include: 1. Straightener: Employed to rectify coil shape defects or distortion. It consists of rollers that gradually straighten the coil. 2. Leveler: Ensures consistent thickness throughout the coil. Utilizes rollers to flatten the coil to the desired thickness. 3. Combination Straightener/Leveler: Integrates both straightening and leveling functions into a single machine. Combines rollers and straightening elements for shape correction and thickness leveling in one pass. 4. Looping Pit: Allows continuous processing of accumulated coils. Serves as a buffer between the entry and exit sections of the leveling line, accommodating variations in coil supply and demand. 5. Tension Leveler: Applies tension during leveling to remove shape defects and achieve a flat, uniform surface. 6. Rotary Shear: Incorporates a synchronized rotary shear to cut the leveled coil accurately and precisely. These examples showcase the diverse coil leveling line configurations used in the steel industry. The choice of configuration depends on factors such as desired product specifications, coil dimensions, processing speed requirements, and budget considerations.
- Q:I mean about if I had a piece of metal, how can i decide that's iron or steel?Sorry for bad English.
- Iron is a chemical element with the symbol Fe, that has no engineering application as it is very soft. You are not likely to come across a piece of metal of pure Iron. Steel is an alloy of Iron that is widely used with different types for various application. The type depends on the alloying elements. An old and rough way of identifying them is to use a chart, that shows the spark pattern when they are subjected to grinding.
- Q:What are the different types of steel finishes for coil protection?
- There are several types of steel finishes used for coil protection, including galvanized, painted, and coated finishes. Galvanized finish involves applying a layer of zinc to the steel surface, providing corrosion resistance. Painted finishes involve applying a layer of paint to the steel surface, offering both aesthetic appeal and protection against corrosion. Coated finishes typically involve the application of a protective coating, such as epoxy or polyurethane, to the steel surface, providing enhanced durability and resistance to various environmental factors.
- Q:Edward Humphrey wants to know... Can I use steel roofing on an older house?
- We are having a metal roof installed on our rental property. We were told by a number of contractors that metal roofing is comparable in price to an asphalt roof. It is all a matter of personal preference. Metal roofing will last for upwards of 50 years, where an asphalt roof, if good quality, will last about 30 years. I personally believe that some house styles just would not look proper or authentic with a metal roof. Hope this helps.
- Q:I am getting a barn soon and I was debating between wood, and steel. I think steel would look nicer [painted of course] and I was wondering which is cheaper. Any extra info would be great. Thanks x
- steel would be cheeper and last longer
- Q:How are steel coils inspected for elongation using elongation testers?
- Steel coils are inspected for elongation using elongation testers by first selecting a representative sample from the coil. This sample is then mounted onto the tester, which applies a controlled force to stretch the steel. The elongation tester measures the change in length of the sample as it is stretched, allowing the calculation of the elongation percentage. This data is crucial for evaluating the steel's ductility and mechanical properties, ensuring it meets quality standards and can withstand various applications.
- Q:Several reading methods of steel tape measure
- Indirect reading methodIn some parts of the steel tape can not be used directly, can use the ruler or ruler, the zero alignment measurement, ruler and measurement direction; steel tape measure distance to a whole scale ruler or ruler, with more than a long reading amount. (3).Some errors in measuring steel tape
- Q:How do steel coils impact the environment?
- Steel coils can have significant environmental impacts throughout their lifecycle. The production of steel coils involves extracting and processing raw materials, which can result in deforestation, habitat destruction, and air and water pollution. Additionally, the energy-intensive manufacturing process contributes to greenhouse gas emissions. Improper disposal or recycling of steel coils can further exacerbate environmental harm. Overall, the environmental impact of steel coils underscores the need for sustainable production practices and responsible end-of-life management.
- Q:hello guys. im totally new to this metalwork things. i need to do it for my project. i need to join stainless steel wires to build some kind of structure (eiffel tow. for example).i already have the wire and the torch. now the question is: where do i get silver solder? is it expensive? and what is flux for? is it necessary? what does it do? is it expensive?thank u for ur time guys! :)
- the flux you need is powdered borax
