Description of ASTM Z80 Prepainted Galvanized Rolled Steel Coil
Prepainted Rolled steel Coil 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 ASTM Z80 Prepainted Galvanized Rolled 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.

- Q: Can you recycle steel? And if you wanted to buy some recycled steel, where would you get it?
- V J is right when he says that steel is the most recycled commodity on the planet. When the price of steel is high, everyone in the steel recycling and forming industry wants their equipment up and running - that's what keeps my husband employed. You would buy some of the steel for a cruise ship from an industrial roll mill, it would likely need to be 3/8' or more thick, not sure how big the rolls would be. Other steel would be purchased from a bar, angle, flat and channel mill, and still other material for your cruise ship would come from a mill that casts beams and other structural parts. My husband made the hull for a 41' steel sail boat by himself, it was all made from steel materials that were readily available in the Vancouver area of British Columbia, Canada. China sells steel - lots and lots and lots of it.
- Q: What metals contain steel? It can be anything except soft iron or steel.
- tricky situation. look from google. it may help!
- Q: Are steel coils resistant to rust and corrosion?
- Yes, steel coils are resistant to rust and corrosion. Steel coils are typically made from carbon steel or stainless steel, both of which have excellent corrosion resistance properties. Carbon steel coils are often coated with a protective layer, such as zinc or a polymer coating, to enhance their resistance to rust and corrosion. Stainless steel coils, on the other hand, are inherently corrosion-resistant due to the presence of chromium, which forms a protective oxide layer on the surface of the steel, preventing rust and corrosion. However, it is important to note that the level of resistance to rust and corrosion may also depend on the specific grade and quality of the steel used in the coils, as well as the environmental conditions they are exposed to.
- Q: Why can hot rolled coils be placed outside?
- Because hot-rolled steel coils are generally used as raw material for semi-finished products, they have to be further used for pickling and cold rolling to make more use. The rust and dust can be removed after pickling
- Q: What are the dimensions of a steel coil?
- The dimensions of a steel coil can vary depending on its intended use and manufacturer. However, typical dimensions include a width ranging from 600mm to 2,200mm, a diameter of 600mm to 2,000mm, and a weight ranging from a few hundred kilograms to several metric tons.
- Q: What are the factors to consider when selecting steel coils for a specific application?
- When selecting steel coils for a specific application, several factors need to be considered. Firstly, the desired strength and durability requirements of the application should be assessed to determine the appropriate grade of steel. Other important factors include the thickness and width of the coils, as well as their surface finish and flatness. The intended use and environment of the application, such as exposure to corrosion or extreme temperatures, should also be taken into account. Additionally, cost considerations and availability of the desired steel grade should be considered during the selection process.
- Q: What are the common coil thicknesses available for steel coils?
- The common coil thicknesses available for steel coils can vary depending on the specific application and industry requirements. However, some of the most common coil thicknesses for steel coils range from 0.5mm to 3mm. These thicknesses are commonly used in various manufacturing processes, including automotive, construction, and appliance industries. For lightweight applications or where flexibility is required, thinner steel coils with thicknesses ranging from 0.5mm to 1.5mm are often used. These thinner coils are suitable for applications such as automotive body panels, roofing, and general sheet metal fabrication. On the other hand, for applications that require higher strength and durability, thicker steel coils with thicknesses ranging from 1.5mm to 3mm are commonly used. These thicker coils are often utilized in heavy-duty construction, structural components, and industrial equipment manufacturing. It is important to note that these are just general ranges, and specific coil thicknesses can vary depending on the specific requirements of a particular project or customer preference. Steel coil thicknesses can be customized to meet specific needs, allowing for greater flexibility in various industries.
- Q: What are the different types of steel coatings for coil protection?
- There are several different types of steel coatings for coil protection, including galvanized coatings, zinc-nickel coatings, organic coatings, and metallic coatings. Galvanized coatings involve applying a layer of zinc to the steel surface to protect it from corrosion. Zinc-nickel coatings offer enhanced corrosion resistance and improved adhesion properties compared to traditional galvanized coatings. Organic coatings, such as paint or polymer coatings, provide a protective barrier against corrosion and can also offer aesthetic benefits. Metallic coatings involve applying a thin layer of a different metal, such as aluminum or tin, to the steel surface to provide corrosion resistance.
- Q: How are steel coils manufactured?
- Steel coils are manufactured through a series of processes that involve the transformation of raw materials into the final product. The manufacturing process begins with the extraction of iron ore, which is then smelted in a blast furnace to produce pig iron. The pig iron is further refined in a basic oxygen furnace to remove impurities and adjust the carbon content. Once the molten steel is obtained, it is continuously cast into large slabs or billets. These slabs are then rolled into thinner sheets or strips through a process called hot rolling. This involves passing the steel through a series of high-pressure rollers, which reduce the thickness and shape the material to the desired dimensions. During this process, the steel is also treated to improve its mechanical properties, such as strength and hardness. After hot rolling, the steel is pickled and cleaned to remove any scale or impurities on the surface. It is then cold rolled to further reduce the thickness and improve the surface finish. Cold rolling involves passing the steel through a set of rollers at room temperature, which increases its strength and dimensional accuracy. To form steel coils, the cold-rolled steel is typically wound tightly into a large coil shape. This is achieved by feeding the steel strip through a series of rollers that gradually wind it into a spiral. The coils are then typically annealed to relieve internal stresses and improve the material's formability. Finally, the steel coils are coated or treated, depending on their intended use. This can involve applying a protective coating, such as zinc or paint, to enhance corrosion resistance or providing a specific surface treatment for improved adhesion in subsequent processes. Overall, the manufacturing of steel coils is a complex process that involves several stages, including smelting, casting, hot rolling, cold rolling, coiling, and surface treatment. Each step contributes to the final product's quality and properties, ensuring that steel coils meet the required specifications for various industrial applications.
- Q: What are the weight ranges of steel coils?
- The weight of steel coils can differ based on their dimensions and intended purpose. In general, steel coils can weigh anywhere from a few hundred pounds to several tons. For instance, hot-rolled steel coils generally fall between 10 and 25 tons, while cold-rolled steel coils can range from a few hundred pounds to 20 tons. The weight of steel coils is also influenced by factors like coil thickness, width, grade, and steel type. Ultimately, the weight range of steel coils is determined by the industry and application requirements.
