Structure of Aluminum Zinc Rolled Coil
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.
Applications of Aluminum Zinc Rolled Coil for Construction Roof
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 methods of coil joining for steel coils?
- There are several different methods of coil joining for steel coils, including welding, laser welding, stapling, and adhesive bonding.
- Q:How are steel coils straightened?
- Steel coils are straightened using a process called leveling. This involves passing the coils through a series of rollers that gradually flatten and align the steel, resulting in straightened coils.
- Q:How are steel coils inspected for coil set?
- Steel coils are inspected for coil set using a variety of methods and equipment. Coil set refers to the curvature or shape of the coil, which can impact its performance and usability in various applications. One common method of inspecting steel coils for coil set is through visual inspection. Experienced operators or inspectors carefully examine the coils for any visible deformities or irregularities in their shape. This can be done by unrolling a portion of the coil and checking for any signs of buckling, twisting, or unevenness. Visual inspection is a straightforward and cost-effective way to identify obvious coil set issues. In addition to visual inspection, more advanced techniques are also used to accurately measure and quantify coil set. One such method is the use of a straight edge or a template. The straight edge is placed along the length or width of the unrolled portion of the coil, and any gaps or deviations from the straight edge indicate the presence of coil set. This method provides a more precise measurement of the extent and severity of the coil set. Another common technique is the use of specialized tools such as a non-contact laser measurement system. This system utilizes lasers to project a line on the surface of the coil and measures the distance between the line and the coil. Any variations in this distance indicate the presence of coil set. This method is highly accurate and provides detailed data about the coil's shape and curvature. Other methods may include using mechanical devices such as rollers or tensioners to unroll and measure the coil's shape. These devices apply controlled pressure to the coil to straighten it out, and any resistance or deviations encountered during the process are indications of coil set. Overall, the inspection of steel coils for coil set involves a combination of visual examination and precise measurement techniques. These methods help identify and quantify any deformities or irregularities in the coil's shape, allowing manufacturers and customers to make informed decisions about the usability and quality of the steel coils.
- Q:Is there a difference between hot rolled and cold rolled steel coils?
- Yes, there is a difference between hot rolled and cold rolled steel coils. Hot rolled steel coils are produced at high temperatures and have a rough, scaled surface with slightly rounded edges. They are generally used for applications that require less precise dimensions and a rougher surface finish. On the other hand, cold rolled steel coils are produced at room temperature and have a smoother surface with tighter tolerances and sharper edges. They are commonly used for applications that require precise dimensions, a smoother finish, and higher strength.
- Q:how many persent of manganese in all types of carbon steel
- i think it is 1.65%...
- Q:I've heard different things bout them, though I do not know this. Oh, and if you know where you can buy some raw or get custom made stuff out of black steel please let me know it would be greatly appreciated. Oh and my friend told me there is a black steel that can be sharpened and silver will be underneath, is this also true? Thank you very much for answering ^^
- Black steel is steel with a surface layer of dark coloured iron oxides used for low pressure hot water heating pipes. Black iron is iron without any finish on it, which is really gray-black in color. they may be the same as many people often confuse iron and steel. Since the steel is simply steel with a covering, it could describe any steel including your silver steel.
- Q:Is it just because brass is reloadable? But what makes it reloadable? What does brass bring to the equation that the steel cased ammo can't do?
- Brass is slightly softer than annealed steel. Both can be reloaded, once or maybe even twice. But STEEL has a tendency to WORK HARDEN, becoming brittle. Which is why it's used for tools and other applications where work hardening is a plus. It's actually designed to do that. Brass does not work harden, because it is a different sort of metal. That's the main reason.
- Q:Are Steel buildings Fire Resistant, just want to know as I am going to owe it . Suggestions required…………..
- What burns in a building are mostly the furnishings and interior, not the frame it's made of. Steel buildings are more expensive to insure against fire than wood frame buildings, because in a fire more steel is damaged by warping and distortion than would happen in a wood-framed structure, and wood structures are easier (and cheaper) to repair. Of course, if everything in a building was non-flammable, fire would never occur. That doesn't usually happen, though, and it's all the flammable stuff that most buildings house inside that burns.
- Q:What are the different types of steel coil loading and unloading devices?
- There are several different types of steel coil loading and unloading devices, including coil lifters, coil hooks, coil tongs, coil grabs, coil c-hooks, coil fork attachments, and coil transfer cars. These devices are used to safely and efficiently handle steel coils during transportation and storage processes.
- Q:Can steel coils be bent or shaped?
- Yes, steel coils can be bent or shaped due to their flexibility and malleability.
