Description of ASTM Z70 Prepainted Rolled Steel Coil for Construction Roofing
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 Z70 Prepainted Rolled Steel Coil for Construction Roofing
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.

- Q: I am wondering what the highest quality steel is used in handgun production.
- The chrome moly alloy used in blued steel guns is the strongest thing out there today. Stainless guns sacrifice a little in strength in exchange for their rust resistance. Every maker has their own special alloys for various parts as well as proprietary techniques for hardening and tempering depending on the use a part will be put to. Keep in mind that the harder you make steel the more brittle it becomes. Especially true in knife blades also. A custom knife blade could be made much harder than they are, but would shatter under hard use.
- Q: rust is not a issue. i was looking a D2 steel but heard story's of it chipping and breaking
- The very best is Damascus steel or the composite samari blade. Talk to the American Bladesmith Society if you are interested in forging your own or buying a forged blank and making the knife yourself. D2 and other similar tool steels are generally not a good choice because they can not obtain very high hardness but they should be tough (resistant to cracking) if they were heat treated properly. There are more ways to heat treat wrong than there are to heat treat right. Although you say rust is not an issue, 440 stainless steel is commonly used for commercial knives, it does not rust, holds a good edge, and is pretty tough.
- Q: What are the common standards and specifications for steel coils?
- In the industry, there are various widely recognized and utilized standards and specifications for steel coils. Some notable ones include: 1. ASTM A36/A36M: This specification is concerned with carbon structural steel shapes, plates, and bars of structural quality. It is intended for use in constructions that involve riveting, bolting, or welding. 2. ASTM A572/A572M: This specification focuses on high-strength low-alloy columbium-vanadium structural steel shapes, plates, sheet piling, and bars. It is applicable for constructions involving bolting, riveting, or welding. 3. ASTM A653/A653M: This specification pertains to steel sheet that is zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) through the hot-dip process. 4. ASTM A1011/A1011M: This specification covers various types of steel sheet and strip in coils, such as hot-rolled, carbon, structural, high-strength low-alloy, high-strength low-alloy with improved formability, and ultra-high strength. 5. JIS G3302: This Japanese Industrial Standard specifies the requirements for hot-dip zinc-coated steel sheet, also known as galvanized steel sheet, and strip. 6. EN 10111: This European standard outlines the requirements for continuously hot-rolled low carbon steel sheet and strip that are suitable for cold forming. 7. ISO 3575: This International Organization for Standardization standard lays down the requirements for hot-dip zinc-coated and zinc-iron alloy-coated steel sheet and strip. These are just a few instances of the prevalent standards and specifications employed for steel coils. It is crucial to note that different industries and applications may have specific demands, thus consulting the relevant standards and specifications for the particular application is always advisable.
- Q: What is the typical weight of a steel coil?
- The typical weight of a steel coil varies widely depending on its size, thickness, and type of steel used. However, a common range for steel coils is between 3 to 25 metric tons.
- Q: How are steel coils used in the production of bridges?

These coils are first uncoiled and then cut, rolled, and welded to create the required bridge sections. The high strength and durability of steel make it an ideal material for bridges, and the use of steel coils allows for efficient and precise manufacturing of these vital infrastructure elements.
- Q: I am a complete idiot when it comes to anything musical, so please forgive me if this is a stupid question. I bought my son his first guitar, acoustic and didnt realize until after I purchased it that it has steel strings. Can I have the strings changed from steel to nylon???
- Haha, You're too cute for me. Did you buy Alex the guitar? Just wait until your boys become the next Jonas Brothers :)
- Q: How are steel coils stored and transported?
- Steel coils are typically stored in warehouses or outdoor storage yards. They are usually stacked horizontally, one on top of the other, with wooden or steel supports placed between each coil to prevent damage. When it comes to transportation, steel coils are usually loaded onto flatbed trucks or shipping containers using cranes or forklifts. It is important to secure the coils properly during transportation to prevent any shifting or damage.
- Q: How do steel coil manufacturers handle international shipping requirements?
- Steel coil manufacturers typically handle international shipping requirements by following a well-defined process. First, they ensure proper packaging and securing of the coils to prevent damage during transportation. This may involve using specialized equipment, such as coil racks or crates. Next, they comply with international shipping regulations and obtain necessary documentation, such as bills of lading and customs clearance forms. They coordinate with freight forwarders or shipping agents to arrange transportation and select the most suitable shipping method, whether it's by sea, air, or land. Throughout the process, manufacturers closely track shipments and communicate with customers to ensure smooth delivery and address any issues that may arise.
- Q: How are steel coils used in the manufacturing of airbags?
- Steel coils are used in the manufacturing of airbags as they provide the necessary structural support and strength to ensure the airbags deploy effectively during a collision. The coils are typically placed within the airbag module to help maintain its shape and prevent it from collapsing on impact, ensuring the airbag can rapidly inflate to protect occupants in a vehicle.
- Q: How are steel coils used in the automotive stamping process?
- Steel coils are a critical component in the automotive stamping process. These coils are essentially large rolls of steel that are unwound and fed into stamping machines. The coils are typically made of high-quality steel and come in various thicknesses and widths to meet the specific requirements of different automotive parts. During the stamping process, the steel coils are fed through a series of dies and presses that shape and form the metal into the desired automotive components. The coils are unwound and passed through a straightener to remove any bends or twists, ensuring a smooth and consistent feed into the stamping machine. The stamping machine then uses a combination of hydraulic or mechanical force to press the steel coil against a die, which is a specially designed mold that gives shape to the metal. The die is often made of hardened steel to withstand the pressure and provide accurate and repeatable results. The steel coil is fed into the stamping machine at a high speed, and as it passes through the die, the metal is formed into various automotive parts such as body panels, doors, hoods, fenders, and other structural components. The stamping process allows for high precision and consistency in producing these parts, ensuring they meet the required specifications and tolerances. Once the metal is formed, it may undergo additional processes such as trimming, piercing, or bending to achieve the final shape. These processes are often performed in subsequent stamping stations or by using progressive dies that combine multiple operations into a single pass. Overall, steel coils play a vital role in the automotive stamping process as they provide the raw material required to produce various components. The use of steel ensures the necessary strength, durability, and safety of the automotive parts while maintaining cost-effectiveness and mass production capabilities.
