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:I was cutting a sheet of steel with an angle grinder when suddenly the rate at which the blade was cutting slowed way down. I tried a few different things, and turned off the tool and looked at the blade. It didn't look damaged, but it definitely was not cutting as quickly. I thought either I had hit a harder section of steel (is that possible? It looked pretty uniform) or the blade had lost it's abrasive quality or something. Also, before this happened I had accidentally cut into the wooden sawhorse that was holding up the steel sheet, but I've done that before with no problem. After a short while the problem fixed itself and the rate of cutting went back to a fast normal. Anyone know why this happened?
- Your blade was overheated. Change it into diamond blade shall do.
- Q:What are the different testing methods used for steel coils?
- There are several testing methods used for steel coils, including visual inspection, dimensional measurements, hardness testing, chemical composition analysis, and various non-destructive testing techniques such as ultrasonic testing, magnetic particle testing, and eddy current testing. These methods help ensure the quality and integrity of steel coils by detecting any defects, flaws, or deviations from the required specifications.
- Q:I want to make a chess set out of stainless steel, but I'm not sure what type of mold I need or where I can go to have the steel melted and molded for me. Any ideas? I live in Southern, NJ.
- I'll buy one. You'll have to machine it from blocks... You could invest in a milling machine - they are like drill presses and lathes all together and more... If you hook it up to your computer, you can do a CNC milling, where you can get really creative and finely detailed. Stainless is heavy and hard, so it'll go through your bits, and you should use the super duty bits as well. I have always wanted an SS chess set, I made a board out of leather. It's really super awesome, just need your pieces now. Or make mine from Plutonium, or Tungsten Carbide.
- Q:How are steel coils used in the production of agricultural storage tanks?
- Steel coils are used in the production of agricultural storage tanks as they serve as the primary material for constructing the tank walls and base. The coils are shaped and welded together to form a sturdy and durable structure that can withstand the weight and pressure of storing agricultural products such as grains, feed, and fertilizers. The steel coils provide the necessary strength and corrosion resistance required for long-term storage in various agricultural environments.
- Q:Can steel coils be coated with anti-fingerprint materials?
- Yes, steel coils can be coated with anti-fingerprint materials. These materials are designed to reduce the visibility of fingerprints and smudges on the surface of the steel, providing a cleaner and more aesthetically pleasing appearance.
- Q:hi, i have a steel block with an unussual composition. does anyone know if this is any particular type?c- .6%, si - .33%, mn - .6%, sulphur - .014%, phosphorous - .013%, ni - 1.69%, Cr, 1.07%, molybdenum - .67%
- You have opened a can of worms. Specific types of steel vary not only by composition but by the way they were made, their physical properties and their morphology (microscopic structure). The composition you have given would fit for High Carbon Steel and Medium Carbon Steel. Go to the reference I've given, it allows you to put in 3 of the components of your alloy and then it gives you a list of possibilities. You can open each candidate individually and see the full composition. Hours of fun. :)
- Q:What are the common methods of transporting steel coils?
- Depending on factors such as coil size, weight, destination, and specific handling requirements, there are various common methods for transporting steel coils. These methods include: 1. Short-distance transportation: For short distances, steel coils are often transported using flatbed trucks. These trucks have a flat trailer bed that allows for easy loading and unloading of the coils. To prevent movement during transit, the coils are secured and strapped down. 2. Long-distance transportation: Rail transport is commonly preferred for longer distances due to its cost-effectiveness and efficiency. Specially designed railcars, known as coil cars or gondola cars, are used to securely hold the coils in place. This method is particularly advantageous for large quantities of steel coils. 3. International or long-distance transport: Shipping by sea is a common method for transporting steel coils internationally or over long distances. The coils are loaded into specialized shipping containers with internal cradles to prevent movement and damage during transit. These containers are then loaded onto cargo ships. 4. Waterway transportation: In regions with navigable waterways, barges can be used to transport steel coils. Similar to ocean freight, the coils are loaded into specially designed containers or barges with cradles to secure them during transport. Barge transport offers an economical and environmentally friendly option, especially for inland waterway transportation. 5. Combined transportation: In certain cases, a combination of different transportation modes, known as intermodal transport, may be used. For instance, steel coils can be initially transported by truck and then loaded onto railcars for long-distance transport. This approach allows for the optimization of cost and efficiency by utilizing the advantages of different transportation modes. It's important to note that the specific method of transporting steel coils can vary based on various factors, including coil size, weight, destination, and any specific handling requirements.
- Q:How did the growth of the steel industry influence the development of other industries?
- At least three ways: 1. Steel as a material that other industries could use to do things that couldn't be done before (for example, construction (skyscrapers, long bridges, etc.)) or could now be done at much lower cost and hence increased the size of the industry (automobiles, bearings, etc.)
- Q:How are steel coils inspected for quality assurance?
- Steel coils are inspected for quality assurance through a combination of visual inspections, measurements, and non-destructive testing techniques. These inspections typically involve checking for surface defects, such as cracks, scratches, or corrosion, as well as ensuring the dimensions and weight of the coils meet the required specifications. Non-destructive testing methods, such as ultrasonic or magnetic particle testing, are also used to detect any internal defects that may not be visible to the naked eye. Overall, these comprehensive inspections help ensure that steel coils meet the desired quality standards.
- Q:What are the environmental considerations of using steel coils?
- There are several environmental considerations associated with using steel coils. Firstly, the production of steel coils requires a significant amount of energy and raw materials, which can contribute to greenhouse gas emissions and environmental degradation. Additionally, the extraction and processing of iron ore for steel production can have negative impacts on land, water, and air quality. Moreover, the transportation of steel coils, especially over long distances, can result in emissions from vehicles and contribute to pollution. Lastly, the disposal of steel coils at the end of their lifecycle poses challenges as they can be difficult to recycle and may end up in landfills, further contributing to waste accumulation. Overall, the environmental implications of using steel coils highlight the need for sustainable practices in their production, transportation, and disposal.
