Description of RAL Scale 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 RAL Scale 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.
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 RAL Scale Z70 Prepainted Rolled Steel Coil for Construction Roofing

- Q: How are steel coils used in the manufacturing of body reinforcements?
- Steel coils are used in the manufacturing of body reinforcements by being processed and shaped into various structural components, such as beams and frames, which provide strength and support to the body of a vehicle. These reinforcements help enhance the vehicle's structural integrity, ensuring safety and protection for the occupants in the event of a collision or impact.
- Q: How do steel coils contribute to energy efficiency in appliances?
- Steel coils contribute to energy efficiency in appliances in several ways. Firstly, steel is a highly conductive material, allowing for efficient heat transfer. This means that appliances with steel coils, such as refrigerators or air conditioners, can cool or heat up faster, reducing energy consumption. Additionally, steel coils are durable and have excellent heat retention properties, meaning that once the desired temperature is reached, the coils can maintain it for longer periods without consuming additional energy. This helps appliances to operate more efficiently and save on electricity usage.
- Q: I am working on a hydrogen generator, but the stainless steel I am using corrodes and turns the water brown. Can anyone tell me if there is stainless steel that does not corrode, and if so, what is it called and where can I get some.Thank you.
- All stainless steel will corrode in certain conditions. Some varieties are worse than others. For instance grade 409 which is used for car exhausts (and other things) will rust. For the most suitable grade call a local steel supplier which carries stainless steel. Some of these companies will have a catalog of available grades and the appropriate uses. It would probably help to let them know what types of chemicals are present and what temperature the water is. You may want to call several suppliers, the quality of answer you get may vary quite a bit from company to company. The cost of exotic grades of stainless can be quite high. you may have to use a less appropriate grade if you can't justify the cost. If corrosion is a very serious concern for this be forewarned that stainless steels can be contaminated by contact with carbon steel (ordinary steel). I have seen rust form on stainless steel after a carbon steel bar was set down on the stainless steel. The carbon steel will leave trace amounts under prolonged contact. I have even seen signs of contamination of stainless steel direct from the supplier.
- Q: What are the different methods of embossing steel coils?
- There are numerous techniques for embossing steel coils, each possessing unique characteristics and applications. Some of the most prevalent techniques include: 1. Hot embossing: By heating the steel coil to a high temperature and pressing it between two engraved rollers, this method allows for intricate designs or textures to be imprinted onto the surface. The heat softens the steel, facilitating the desired pattern transfer. 2. Cold embossing: In contrast to hot embossing, cold embossing does not require heating the steel coil. Instead, it employs pressure and specifically designed dies or stamps to produce the desired pattern. Cold embossing is commonly used for simpler designs or when working with heat-sensitive materials. 3. Roller embossing: This technique involves using a series of rollers with engraved patterns to imprint the design onto the steel coil. The coil is passed through the rollers, and the applied pressure transfers the pattern onto the surface. Roller embossing is often utilized for larger-scale production, delivering consistent and uniform results. 4. Laser embossing: A modern method that employs laser technology to create patterns on steel coils. The laser beam selectively melts or vaporizes the metal, generating the desired design. Laser embossing offers high precision and flexibility, making it suitable for intricate and detailed patterns. 5. Press embossing: This technique utilizes a press machine equipped with custom-made dies to imprint the desired pattern onto the steel coil. The coil is positioned between the dies, and the press machine applies pressure, transferring the pattern onto the surface. Press embossing is commonly used for large-scale production, achieving high-speed and high-volume embossing. Ultimately, the choice of embossing method depends on various factors, including design complexity, production volume, material properties, and cost considerations. Each technique possesses advantages and limitations, necessitating careful selection by manufacturers based on their specific requirements.
- Q: How are steel coils used in the manufacturing of automotive accessories?
- Steel coils are used in the manufacturing of automotive accessories as they are processed and shaped into various components such as brackets, frames, and supports. These coils are typically cut, molded, and stamped into specific shapes before being assembled into the final product, adding strength and durability to the accessories.
- Q: I read that contrary to popular belief, today's folded steel swords are only made that way for tradition and cosmetics. In the past steel was very impure and therefore had to be folded in order to make a good sword. Today's steel manufacturing provides very pure steel and so folding the metal only makes it look nicer, but does nothing to improve the function of the blade.What do you think of this?

- Q: Can steel coils be coated with electrically conductive materials?
- Yes, steel coils can be coated with electrically conductive materials.
- Q: I bought my Gerber Scout for 29 bucks at the local Walmart a couple months ago, and so far it's performed better than any of my previous knives (a couple of low quality Bucks, and a Winchester). However, my friend just bought a 50 dollar Buck knife and I absolutely love it, so I'm debating trading mine in and pitching in a bit of cash for the same kind.What troubles me is the fact that everybody seems to be bashing 440A steel. I hear a lot of bad things about it; how it is soft, chips easy, dull quickly, etc. How bad is 440A steel really, and would it be worth trading in my Gerber plus about 30 cash for a Buck Vantage Pro? Apparently the Vantage Pro uses S30V steel, so is it really that big of an upgrade, from 440A to S30V? Thank you.
- 440 steel is fine for most knives, but there are better quality steels out there for specialized uses. If you like the knife you have, don't worry about what other people say. If you like the new knife more, trade for it. Sometimes I question why people have to ask so many questions about what's better than what.
- Q: Why can't the coil weight be too low?
- And may make the level stacked steel coil collapse, rolling, produce production safety accidents.
- Q: How are steel coils tested for dimensional accuracy?
- Steel coils are tested for dimensional accuracy through various methods such as measuring their width, length, thickness, and diameter using specialized tools like calipers, micrometers, or laser measurement systems. These measurements are compared against the specified tolerances provided by the manufacturer to ensure that the steel coils meet the required dimensional standards.
