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: My company want to welding stainless steel, do not know to use what welding machine?
- They actually make a stainless rod now that can be used with most arc welders
- Q: Is 440 steel relatively strong or weak?
- Grade 440C is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. Its very high carbon content is responsible for these characteristics, which make 440C particularly suited to such applications as ball bearings and valve parts. Grades 440A and 440B are identical except for slightly lower carbon contents (0.60 - 0.75% and 0.75 - 0.95% respectively); these have lower attainable hardnesses but slightly higher corrosion resistances. Although all three versions of this grade are standard grades, in practice 440C is more available than the A or B variants. A free-machining variant 440F (UNS S44020) also exists, with the same high carbon content as 440C. Again this grade is not readily available in Australia. Martensitic stainless steels are optimised for high hardness, and other properties are to some degree compromised. Fabrication must be by methods that allow for poor weldability and usually also allow for a final harden and temper heat treatment. Corrosion resistance is lower than the common austenitic grades, and their useful operating temperature range is limited by their loss of ductility at sub-zero temperatures and loss of strength by over-tempering at elevated temperatures. Key Properties These properties are specified for bar product in ASTM A276. Similar but not necessarily identical properties are specified for other products such as plate and forgings in their respective specifications.
- Q: Steel or stainless steel
- Steel often has impurities that can generate fumes, which cause a fever identical to smoke inhalation. You always need to be concerned about what you are breathing around hot metal.
- Q: How do steel coils compare to aluminum coils?
- Steel coils and aluminum coils possess distinct characteristics that render them suitable for varying purposes. Firstly, steel coils are renowned for their robustness and durability. They can endure high temperatures and exhibit greater resistance to damage in comparison to aluminum coils. Consequently, steel coils are an ideal choice for heavy-duty industrial applications necessitating sturdy materials, such as construction, automotive manufacturing, and the oil and gas industries. Additionally, steel coils boast heightened corrosion resistance, enabling their usage in outdoor environments characterized by harsh conditions. On the contrary, aluminum coils are lighter in weight and possess a higher strength-to-weight ratio than steel coils. This renders them exceptionally well-suited for industries wherein weight serves as a critical factor, such as aerospace and transportation. Furthermore, the malleability of aluminum coils facilitates easier shaping and forming, thereby proving advantageous in industries like packaging and consumer electronics. Moreover, aluminum coils exhibit superior thermal conductivity when compared to steel coils, rendering them more efficient in heat transfer applications. This particular attribute proves beneficial in industries such as HVAC (heating, ventilation, and air conditioning) and refrigeration, where the achievement of efficient heat exchange is of utmost importance. Concerning cost, steel coils generally prove more affordable due to the lower cost of raw materials. However, aluminum coils can yield long-term cost savings as they require less maintenance and possess a longer lifespan owing to their resistance to corrosion. In conclusion, the selection between steel coils and aluminum coils hinges on the specific requirements of the application at hand. Steel coils are favored for their strength, durability, and corrosion resistance, while aluminum coils excel in lightweight applications, heat transfer, and malleability.
- Q: What are the dimensions of steel coils used in the metalworking tool industry?
- The metalworking tool industry has a wide range of dimensions for steel coils, which can vary depending on the specific application and requirements of the tool. However, there are certain dimensions that are commonly observed in this industry. Steel coils used in metalworking tools typically come in different widths, ranging from 24 inches to 72 inches. The thickness of the coils can also vary, with common thicknesses ranging from 0.020 inches to 0.250 inches. Moreover, the length of the coils can vary significantly, with standard lengths usually falling between 100 feet and 2000 feet or even more. These dimensions are selected based on several factors, such as the type of metal being worked, the specific tool being used, and the desired outcome of the metalworking process. Additionally, other factors like the weight and handling capabilities of the tool, as well as the efficiency of the manufacturing process, may also influence the dimensions of the steel coils used. To ensure the appropriate dimensions for steel coils in the metalworking tool industry, it is essential to consult with manufacturers, suppliers, or industry experts. This is crucial because these dimensions can vary based on specific needs and preferences.
- Q: I saw this really pretty ring online and it was made of steel. Is this a good ring? If I were to wash my hands with it on, would it rust and turn my finger green?
- Steel rust is brown not green! Very much expected to be of one type of stainless steel, and you should have no problem.
- 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?
- I don't know that stainless can be laminated to steel very easily. Stainless is a little more expensive. The problem comes in that stainless is much harder to machine that normal gun steel. With laminated steel, you would still have the problem of machining the stainless. Occasionally firearms are nickle plated or barrels are chrome lined.
- Q: How are steel coils inspected for surface finish using profilometry?
- Steel coils are inspected for surface finish using profilometry by measuring the surface topography using a profilometer. The profilometer scans the surface of the steel coil and records the deviations from the ideal surface. This data is then used to determine the roughness, waviness, and other surface parameters of the steel coil, providing a quantitative assessment of its surface finish quality.
- Q: Just two sentences on a detailed description on what the steel industry is
- The steel industry is an industry that produces steel. It is one of the largest industries in the world, with China as the leading steel producer
