Structure of Aluminum Zinc Rolled Coil

 Prepainted aluminum Zinc rolled Coil for Construction

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:What are the different types of steel coil coatings?
There are several different types of steel coil coatings that are used for various purposes. Some of the most common types include: 1. Galvanized Coating: This is a zinc-based coating that provides excellent corrosion resistance to steel coils. It is often used in outdoor applications where the coils are exposed to harsh weather conditions. 2. Galvannealed Coating: Similar to galvanized coating, galvannealed coating also contains zinc, but it is heat-treated to form an alloy with the steel surface. This type of coating provides better paint adhesion and is often used in applications where the coated coils will be painted or further processed. 3. Pre-painted Coating: As the name suggests, pre-painted coatings are applied to steel coils before they are delivered to customers. These coatings can be made of various materials, including polyester, polyurethane, epoxy, or fluoropolymer. Pre-painted coils are commonly used in construction, automotive, and appliance industries. 4. Electro-galvanized Coating: This coating is applied to steel coils through an electroplating process, where a thin layer of zinc is deposited on the surface of the steel. Electro-galvanized coatings provide good corrosion resistance and are often used in indoor applications or where a thinner coating is desired. 5. Aluminized Coating: Aluminized coatings are made by applying a thin layer of aluminum to the surface of steel coils. This type of coating provides excellent heat resistance and is commonly used in exhaust systems, ovens, and other high-temperature applications. 6. Organic Coatings: Organic coatings are typically applied to steel coils to provide additional protection against corrosion and improve aesthetics. These coatings can be in the form of paints, lacquers, or powder coatings, and they can be customized to meet specific requirements in terms of color, gloss, and durability. Overall, the choice of steel coil coating depends on the specific application, environmental conditions, desired aesthetics, and performance requirements.
Q:Is a steel plate the same as a steel coil?
Generally speaking, they can be used interchangeably, and the purchase price of the plate is slightly cheaper.
Q:What is the weight range of steel coils?
The weight range of steel coils can vary greatly depending on the specific type and dimensions of the coil. However, typically, steel coils can weigh anywhere from a few hundred kilograms to several tonnes.
Q:What are the common thicknesses available for steel coils?
The specific requirements and applications determine the available common thicknesses for steel coils. However, various industries commonly produce and use certain standard thicknesses. Typically, steel coils can range in thickness from 0.005 inches to 0.5 inches or more, depending on the type of steel and its intended use. For instance, in automotive manufacturing, where steel coils are utilized for body panels and structural components, the thicknesses commonly range from 0.5 mm (0.020 inches) to 3 mm (0.118 inches). In the construction industry, steel coils are employed for roofing, siding, and structural framing. The common thicknesses can vary from 0.014 inches to 0.062 inches, depending on the specific application and structural requirements. Similarly, appliances manufacturing, such as refrigerators, washing machines, or HVAC systems, frequently employ steel coils with thicknesses ranging from 0.018 inches to 0.035 inches. It is important to note that these are only a few examples of common thicknesses, and variations can occur based on the specific requirements of different industries and applications. Custom thicknesses can also be produced upon request to meet unique needs in various sectors.
Q:What are the different types of welding used for steel coils?
There are several different types of welding used for steel coils, depending on the specific requirements and applications. Here are some of the most common types of welding techniques used for steel coil fabrication: 1. Shielded Metal Arc Welding (SMAW): Also known as stick welding, it involves the use of a flux-coated electrode and an electric current to create an arc between the electrode and the base material. SMAW is a versatile and widely used welding technique suitable for various steel coil applications. 2. Gas Metal Arc Welding (GMAW): Commonly known as MIG (Metal Inert Gas) welding, GMAW uses a continuous wire electrode and a shielding gas to protect the weld pool from atmospheric contamination. GMAW is known for its high welding speed and ease of automation, making it a popular choice for steel coil manufacturing. 3. Flux-Cored Arc Welding (FCAW): Similar to GMAW, FCAW uses a tubular electrode with flux inside. The flux provides both the shielding gas and additional alloying elements, resulting in increased efficiency and improved weld quality. FCAW is often used in high-speed welding applications for steel coils. 4. Gas Tungsten Arc Welding (GTAW): Also known as TIG (Tungsten Inert Gas) welding, GTAW uses a non-consumable tungsten electrode and an inert gas, typically argon, to shield the weld area. GTAW produces high-quality, precise welds with excellent control over the heat input, making it suitable for thin steel coil materials and critical welding applications. 5. Submerged Arc Welding (SAW): This welding technique involves the use of a continuously fed wire electrode and a granular flux that covers the weld area. The arc is submerged under the flux, providing excellent protection and reducing the need for post-weld cleaning. SAW is commonly used for welding thick steel coils due to its high deposition rates and deep penetration capabilities. These are just a few examples of the different types of welding techniques used for steel coil fabrication. The choice of welding method depends on factors such as the specific steel grade, thickness, desired weld quality, production speed, and cost considerations. It is essential to select the appropriate welding technique to ensure the durability and performance of the steel coils in various applications.
Q:What is the difference between hot rolled and cold rolled steel coils?
The main difference between hot rolled and cold rolled steel coils is the process by which they are made. Hot rolled steel coils are produced by heating the steel above its recrystallization temperature, allowing it to be easily shaped and formed. This process results in a rougher surface finish and less precise dimensions. On the other hand, cold rolled steel coils are produced by further processing hot rolled coils through a series of rolling mills at room temperature. This process results in a smoother surface finish, tighter tolerances, and improved mechanical properties.
Q:What is the role of steel coils in the supply chain?
Steel coils play a crucial role in the supply chain as they are used for a variety of purposes, such as transportation, storage, and manufacturing. They serve as a convenient and efficient way to transport large quantities of steel, ensuring that it reaches its destination safely and in optimal condition. Additionally, steel coils facilitate storage by allowing for easy stacking and organization, maximizing space utilization. Moreover, they are a primary raw material for various industries, especially manufacturing, where they are used in the production of a wide range of products, including automobiles, appliances, construction materials, and more.
Q:Who started or popularized the use of the steel guitar in country music? Early country songs contained no steel guitars but by 1950 the steel guitar had become a staple of country music.
As I don't know for sure I have a couple of really good guesses. I would say either Jerry Byrd of Ernest Tubb's Texas Troubadours or Don Helms of Hank Williams' Drifting Cowboys. I can tell you for sure that Bud Isaacs was the first player to use a pedal steel guitar on a hit recording: Slowly by Webb Pierce in 1953.
Q:I've been looking into battle-ready katanas a lot lately. And I've come across some debates between the best forges and steels to be used for them. The functional katanas I use now are Musashi brand katanas, using 1045 carbon steel. They each cost roughly $200-$250. The straight carbon steels are mentioned in the debates, but they aren't very sophisticated in their design. Now the higher end of this middle class of katana ($250-$1000) uses higher carbon. spring, damascus, and other various steels and combinations. I've heard a lot about the strength of damascus steel and it's cutting power. But I look for more than that. I've also been looking at (and for) durability, flexibility, and how well it stands up to contact. So I guess what I'm asking is for the opinion of people who have used these steels, and an answer on what the community thinks is the best steel for a mid range ($250-$1000) battle-ready katana. Looking forward to some good answers.

Q:Why does steel with several composites have a greater hardenability from quenching than low carbon steel alloys?Any help would be great
Bit tricky to explain and I don't know muh about it but steel on its own has lost of gaps in it ( the molecular structure) and when carbon is added thos gaps are filled, I think of it like this: it is easier to punch through expanded polystyrene( with all the little balls) than unexpanded(just a lump of plastic) as the balls are not properly joined and have air pockets between them.
