Structure of Al-Zinc coated steel 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 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 just bought a used Taurus 85 stainless 38 spl revolver, it's about 25 years old but looks like new. This is my first stainless steel gun. I'm wondering if there's any special things I need to be aware of or cleaning methods? I'm also wondering if stainless steel could rust? in theory stainless means it cannot get stained or rusty. I have a chrome bore AK, cleaning is always super easy, wondering of cleaning a SS revolver would be the same.
- Yes, stainless steel will rust. It is not rust proof, it is rust resistant. You still should oil your gun after you shoot it.

- Q: What are the different types of edge conditions in steel coils?
- Some of the different types of edge conditions in steel coils include mill edge, slit edge, and sheared edge. Mill edge refers to the original edge produced during the steel manufacturing process. Slit edge is created when the steel coil is cut into narrower strips. Sheared edge is formed when the coil is trimmed using a cutting tool. These various edge conditions have different characteristics and can impact the usability and appearance of the steel coils.
- 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: Steel Strings on your guitar or nylons? Why?
- There is no OR about it. You CANNOT use steel strings on a nylon string guitar because the increased tension will actually warp the top of the guitar and eventually pull the bridge right off! (I have seen it happen several times!) Although it is possible to put nylon strings on a steel string guitar it is not recommended. Nylon strings do not have as much tension as a steel string guitar is designed for. Steel string guitar necks are actually designed with a bit of back bow to compensate for the high tension of steel strings. Nylon strings have a much lower tension which could cause the neck of a steel string to settle slightly, which could actually cause the strings to fret out. It is not common, but it does happen. So keep your guitars happy and only string them with the proper strings.
- Q: How are steel coils used in the production of steel washers?
- Steel coils are used in the production of steel washers by being processed through a stamping or cutting machine. The coils are fed into the machine, which then cuts or punches out individual washer shapes. This process allows for efficient mass production of steel washers with consistent shape and size.
- Q: What is the difference between hot-rolled and cold-rolled steel coils?
- The main difference between hot-rolled and cold-rolled steel coils lies in the production process. Hot-rolled steel coils are made by heating the steel above its recrystallization temperature, causing it to become malleable and allowing it to be rolled into the desired shape. This process results in a thicker and less precise product with a rough surface. On the other hand, cold-rolled steel coils are made by cooling the hot-rolled steel and then passing it through rollers at room temperature. This process enhances the steel's strength, durability, and dimensional accuracy, resulting in a thinner and smoother product that is ideal for applications requiring precision.
- Q: Im looking at some knives and am wandering if they use good steel one is this case knife and its 54 dollars Do they use good steel or not Iv never had a good experience with Case but am wandering if they use good steel now? if you all have any other recommendations let me hear them I got my Selection from here so any others wont hurt. so basic break down does case use good steel know?
- Case knives are top quality in workmanship. Many have collectors vlaue. I once found an antique four-bladed Case knife is a school yard that had a bone handle. There are basically three types of knives purchased by those who purchase them for practical uses: Pocket knives, made principally for whittling and gneral light use Lock bladed knives Sheath knives I'm not including such novleties as switchblades or throwing knives The latter two types of knives are designed more for outdoor use. Typically they are more duarble and have high quality steel that enables the knife to hold an edge for a longer period of time than a knife made of softer steel. Pocket knives, by contrast, have smaller, thinner blades. Moreover, their steel tends to be a little softer. Comparable brands to Case would include Boker, Old- Timer and Uncle Henry (both Schrade-Walden tradenames), Camillus and others. Overall, I think you would be pleased with a Case knife. Their quality certainly exceeds such brands as Imperial or Queen.
- Q: How are steel coils used in the manufacturing of appliances?
- Steel coils are used in the manufacturing of appliances as a primary raw material for constructing the outer body and internal components, such as frames, panels, and structural supports. The steel coils are processed and transformed into various shapes and sizes, ensuring the durability and strength required for appliances.
