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: I have been searching on pots and pans, how can I find out if it's really stainless steel, someone told me if a magnet sticks to it it's real stainless steel is this true?
- Some types of stainless are magnetic and some are not. being magnetic isn't a reliable way to tell the difference. In fact, only the cheapest pots would be made out of grades of stainless that are magnetic. Stainless pots/pans are generally made of non-magnetic types, but then again, aluminum isn't magnetic either. Aluminum and stainless are superficially very similar.
- Q: How are steel coils used in the production of automotive wheels?
- Steel coils are used in the production of automotive wheels by being formed into flat strips, which are then cut, shaped, and welded to create the wheel rims. The steel coils provide the necessary strength and structural integrity required to withstand the weight and pressure exerted on the wheels while driving.
- Q: 1045 surgical steel.
- There are many ways to sharpen knives. I guess your question is whether to use the steel that comes with knives, or a stone. Steels are only to straighten the edge, which is stropping. They won't sharpen a truly dull knife. For that you need a real sharpening system, of which a whet stone is one. The edge of a knife will get wavy with use - that's what the steel is for, to true it back up.
- Q: I want to know if Diamond is stronger than Steel.
- Diamond is harder than steel, as diamond can scratch steel, but steel can't scratch diamond. However, I think steel is more structurally stable than diamond. Besides, how can you afford diamond girders, not even mentioning the impossibility of making a diamond that large.
- Q: How are steel coils processed for cold rolling or hot rolling?
- Steel coils are processed for cold rolling or hot rolling through a series of steps. For cold rolling, the steel coils are first cleaned and pickled to remove any impurities. They are then passed through a series of rolling mills, where the steel is gradually reduced in thickness and elongated. This process improves the steel's strength and surface finish. In contrast, for hot rolling, the steel coils are heated to high temperatures and then passed through a series of rolling mills. The hot rolling process allows for greater deformability and shaping of the steel, resulting in different thicknesses and shapes.
- Q: How are steel coils used in the production of electrical wiring?
- Steel coils are used in the production of electrical wiring as a core material for the conductors. The steel coils are typically shaped into a cylindrical form and coated with an insulating material. This helps in providing structural support to the wiring and also enhances its conductivity and durability.
- Q: Can steel coils be coated with anti-graffiti materials?
- Yes, steel coils can be coated with anti-graffiti materials. These materials create a protective layer that can prevent graffiti from adhering to the surface, making it easier to remove any unwanted markings.
- Q: What are the different types of steel coil storage containers?
- There are several types of steel coil storage containers, including coil racks, coil cradles, coil saddles, and coil cars.
- Q: Bronze came before steel, right? thanks
- Yes, bronze was created a long time before steel. Steel came a long time after iron too.
- Q: How are steel coils inspected for chemical composition?
- Steel coils are inspected for chemical composition through a process called spectroscopic analysis. This involves taking a small sample from the coil and subjecting it to various tests, such as X-ray fluorescence or optical emission spectroscopy, to determine the precise elemental composition of the steel. This ensures that the steel meets the required specifications and quality standards.
