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:How are steel coils protected during transportation?
- Steel coils are typically protected during transportation by being wrapped in layers of protective materials such as plastic or paper, and then secured onto pallets or placed inside specialized containers. This helps prevent damage from moisture, dust, and other external elements, ensuring the coils arrive at their destination in good condition. Additionally, proper handling and loading techniques are employed to minimize the risk of any physical damage during transportation.
- Q:Can steel coils be stored in a corrosive environment?
- Ideally, steel coils should not be stored in a corrosive environment as exposure to corrosive elements can lead to degradation and damage to the steel surface. Corrosion can weaken the structural integrity of the coils and affect their performance. To ensure the longevity and quality of the steel coils, it is best to store them in a dry and non-corrosive environment.
- Q:How are steel coils used in the manufacturing of automotive springs?
- Steel coils are used in the manufacturing of automotive springs as they provide the necessary strength and flexibility required for suspension systems. These coils are shaped, heated, and tempered to achieve the desired spring rate and durability, ensuring a smooth and controlled ride for vehicles.
- Q:On a fixie frame what should i get an aluminum frame or a steel frame
- Steel will ride smoother, but be heavier. Aluminum is lighter, but you will feel more of the small bumps in the road. IMHO - steel is real - but only on a road bike with gears for around town or touring. Fixed gear bikes? You can keep 'em. I wouldn't own one if it were free.
- Q:Which is more reactive? Zinc or Steel? And why?
- Zinc. Steel is an alloy consisting mostly out of iron, In the reactivity seris, zinc is more reactive than iron. Therefore, zinc is more reactive than steel
- Q:I really need help what is the origon of stainless steel?
- Stainless steel is regular steel. They just remove most of the carbon out of it. Carbon it the reactive element within the steel that makes it rust, tarnish, etc...
- Q:I'm getting my nose pierced, meaning that i have to keep the piercing in for a prolonged time. i've always had reactions when wearing sterling silver or fake earrings (i dont know what types of metal they were) after wearing it overnight. Will I get a reaction on my nose piercing if the stud is surgical steel?
- The chances of a reaction from the stud is minimal. Surgical steel is an alloy specifically designed to make sterile safe surgical equipment. Often made with titanium or nickel, surgical steel is highly reactive and forms an oxidized layer when made. This layer creates a stable surface. The titanium and nickel are both very hard and resistant to scratches which make for easy sterilization. This will help keep your piercing clean. Be sure to follow the directions you receive when you get your piercing and keep it clean.
- Q:What are the different methods of surface inspection for steel coils?
- There are several different methods of surface inspection for steel coils, each with its own advantages and limitations. Some of the most commonly used methods include: 1. Visual Inspection: This is the simplest and most basic method, where an inspector visually examines the surface of the steel coils for any defects such as scratches, dents, or discoloration. While this method is subjective and dependent on the skill and experience of the inspector, it can be a cost-effective option for detecting obvious surface defects. 2. Magnetic Particle Inspection (MPI): This method involves applying a magnetic field to the steel coil and then applying iron particles on the surface. Any defects or cracks in the surface will disrupt the magnetic field, causing the particles to gather at those areas and making the defects visible. MPI is particularly useful for detecting surface cracks and defects that may not be easily visible to the naked eye. 3. Eddy Current Testing (ECT): ECT is a non-destructive testing method that uses electromagnetic induction to detect surface defects on steel coils. A probe with a coil is placed near the surface of the coil, generating an alternating magnetic field. Any changes in the electrical conductivity or magnetic permeability of the steel due to surface defects will cause a change in the induced current, which can be detected and analyzed. ECT is effective for detecting cracks, corrosion, or other surface irregularities. 4. Ultrasonic Testing (UT): This method uses high-frequency sound waves to inspect the surface and subsurface of steel coils. A transducer sends ultrasonic waves into the steel, and the reflected waves are analyzed to detect any changes or anomalies in the material. UT can identify defects such as cracks, delaminations, or voids within the coil, providing valuable information about the overall structural integrity of the steel. 5. Optical Inspection: This method utilizes advanced imaging techniques, such as cameras or laser scanners, to capture high-resolution images of the surface of steel coils. These images can be analyzed for defects, such as scratches, pits, or other irregularities. Optical inspection can provide detailed information and is often used in conjunction with other methods for a comprehensive inspection. It is important to note that each method has its own limitations and may be better suited for specific types of defects or surface conditions. Therefore, a combination of these methods is often employed to ensure a thorough and accurate inspection of steel coils.
- Q:This needs to be in a percentage by mass. Could you please also reference where this info has come from. Thanks.
- Steel is produced in different grades,depending on the amount of iron, and chromium, and any other alloying metal that might be in that particular grade. Any good welders hand book would be a good source of information on steel and its properties.
- Q:I'm kind of confused as to how the difference between a stainless steel and blued steel firearm is sometimes only $20 or so. Isn't stainless steel fairly more expensive to manufacture than plain carbon steel? Are some stainless steel firearms simply stainless steel finished with carbon steel underneath?
- Fill the pot up w/cold water to cover the burned on rice. Bring it up to a boil. Do it again w/some high powered soap in the mix. This time let the water sit in the pan until its luke warm, dump it out and scrub it up w/the plastic scouring pad. You should be all set.
