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.

- Q: I've created something but it's a huge secret. Anyways I need to know everything and anything about steel. Like the iron steel. ANYTHING AND EVERYTHING. Best answer goes to the person with the most correct information. Please this is really important.
- If you want to know everything about steel, there's no way you're going to get an answer on Yahoo that is comprehensive enough. What you want to do is get some books on steel metallurgy, engineering properties of materials, and maybe machine design depending on your application. Topics will include molecular structure, material properties, alloying, stress and strain, work hardening, creep, computing damage and lifetime cycles, corrosion, toughness vs hardness, heat treating, and a ton of others. If you want to sharpen steel, that is a whole topic in itself concerning different blade profiles and their sharpness, edge holding, ease of sharpening, type of grind etc.
- Q: I don't know why but I'm having a VERY difficult time finding the melting point of 1008 steel.
- It is still the same for 1008 steel. Go to the bottom and see the listing of the grades it covers. Since the only difference between the 1006 and 1008 steel is a few micro amounts of alloys and by far the greatest majority or main component is iron (99%), as a general melt temperature , 2750 F is the melt temperature at which the other alloys are added to the charge to fine tune the mix. Just like adding salt to distilled water actually lowers the boiling point of water, adding alloys to iron decreases the melting point of iron. The iron melts at 2800F, but once alloys to make the 1008 grade are added, it decreases melt temp to 2750F. Since the melting point of pure iron is 2800F, the temperature is actually decreased by adding these impurities of alloys. These alloys are tested while the mix is starting to come down from a pure melt, steel is sampled. and then alloys below are checked and added to make the 1008 steel. The steel is maintained at 2750 F so that the less volatile alloys don't boil off before combining with steel. Minimum Properties Ultimate Tensile Strength, psi 43,900 - 51,900 Yield Strength, psi 26,100 - 34,800 Elongation 42 - 48% Chemistry Iron (Fe) 99% Carbon (C) 0.08% Manganese (Mn) 0.6% max Phosphorus (P) 0.035% max Copper (Cu) 0.2% min Sulfur (S) 0.04%
- Q: What are the different methods of coil welding for steel coils?
- There are several different methods of coil welding for steel coils, including resistance welding, laser welding, and induction welding. Resistance welding involves applying pressure and passing an electrical current through the coils to create a weld. Laser welding utilizes a high-powered laser beam to melt and fuse the edges of the coils together. Induction welding involves using electromagnetic fields to heat and fuse the coils. Each method has its own advantages and is chosen based on the specific requirements of the application.
- Q: Steel is no doubt a better constructin material but it is only in practice in developed country.i would like that we should high lights the benifits and negatives of steel to make the steel more clear as a construction material.Hope some expert to address this topicMD
- Steel Structure considered as the most efficient and fast in completion of any project, specially the high rise buildings, also the logistics during construction is less complicated than the normal methods, Steel Structure has so many advantages vs the disadvantages, and highly recommended for commercial buildings
- Q: Can steel coils be reused?
- Yes, steel coils can be reused. They are often recycled and used in various industries such as automotive, construction, and manufacturing. The coils can be melted down and reshaped into new products, reducing the need for new raw materials and promoting sustainability.
- Q: How are steel coils processed for further use?
- Steel coils are typically processed for further use through a series of steps. First, the coils are uncoiled and fed into a machine that straightens and levels them. Then, the steel is cut into the desired length and width. Next, the edges are trimmed and any defects are removed. The coils are then cleaned, treated, and coated to enhance their corrosion resistance and appearance. Finally, the processed coils are either stored or transported to manufacturers who transform them into various products such as automotive parts, appliances, construction materials, and more.
- Q: What is the standard thickness of steel coils?
- The specific application and industry requirements dictate the standard thickness of steel coils, which can vary. Generally, steel coils are obtainable in thicknesses ranging from 0.5mm to 10mm. Various factors, including intended use, structural requirements, and manufacturing processes, influence the desired thickness of a steel coil. Heavier applications that necessitate increased strength and durability typically employ thicker coils. Conversely, thinner coils are suitable for lighter applications where flexibility and weight reduction are crucial. To determine the appropriate thickness for steel coils in a particular application, it is essential to consult industry standards and specific project requirements.
- Q: What are the common surface finishes available for steel coils?
- There are several common surface finishes available for steel coils, depending on the desired application and aesthetic requirements. One of the most common surface finishes is hot-dip galvanized, which involves coating the steel coil with a layer of zinc. This finish provides excellent corrosion resistance and is commonly used in outdoor applications where the steel is exposed to moisture and harsh weather conditions. Another popular surface finish is electro-galvanized, which is achieved by applying a thin layer of zinc to the steel coil through an electroplating process. This finish also provides good corrosion resistance but is generally not as durable as hot-dip galvanized. Additionally, steel coils can be coated with a layer of paint or polymer to enhance their appearance and provide additional protection against corrosion. These coatings can be applied in various colors and finishes, such as matte or glossy, to suit specific aesthetic requirements. Furthermore, steel coils can undergo a process called mill finish, which involves leaving the steel in its raw and untreated state. This finish is often used when the steel coil will undergo further processing or coating at a later stage. Other surface finishes for steel coils include stainless steel finish, which is achieved through a passivation process to enhance the steel's resistance to corrosion, and brushed or polished finishes, which are typically used for decorative purposes. Overall, the choice of surface finish for steel coils depends on factors such as the intended use, environmental conditions, and desired appearance, with each finish offering its unique advantages and characteristics.
- Q: Why is it usually scorned by the shooting community to use steel cased ammo (like Wolf)? Always hear corrosive and steel is bad for the extractor/firing pin. Hulp a simpleton out!
- Here's a true life example: My Bushmaster AR15 extractor rips the lip/rim off the steel casing leaving the fired round jammed into the chamber. It takes a push rod to remove the casing. It happens pretty frequently, and I recently took half a brick of the junk and dropped it off at my local gun store on amnesty day. I've never had that issue with brass.
- Q: What is the average lead time for receiving replacement steel coils?
- The average lead time for receiving replacement steel coils can vary depending on various factors such as the supplier, location, and specific requirements. It is recommended to contact the supplier directly for an accurate estimation of the lead time.
