Description of 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 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.

- Q: How are steel coils protected against scratches and damage?
- Steel coils are protected against scratches and damage through various methods such as applying protective coatings, using edge protectors, securely packaging them with appropriate materials, and ensuring careful handling during transportation and storage.
- Q: Can steel coils be coated with luminescent materials?
- Yes, steel coils can be coated with luminescent materials. This process involves applying a layer of luminescent material onto the surface of the steel coils, allowing them to emit light in the dark or under specific lighting conditions.
- Q: So finally got around to watching man of steelnow i heard a few times that batman was in iti didn't se him.in the film is it something subtle I've just missed or is he not in it?when i googled it got loads of results for them being together in the new film but nothing about man of steel 2013
- Batman himself is not in Man of Steel; he is in the upcoming sequel to Man of Steel though, titled Batman v Superman: Dawn of Justice There are subtle references to Batman in Man of Steel though. When Superman and Zod are fighting and they fly up above the Earth, the satellite they fight next to has the Wayne Enterprises logo on it (Wayne Enterprises is the name of the company owned by Bruce Wayne AKA Batman). Also (and this one is very hard to spot) there is a part where Zod throws Superman into an office building, and just for a split second you can see a poster on the wall which says Keep Calm and Call Batman So no, Batman is not in Man of Steel, although he is in the sequel and he is referenced in Man of Steel.
- Q: Can steel coils be transported by air?
- Yes, steel coils can be transported by air.
- Q: what is the chemical process that makes steel harder when it is heated and cooled rapidly?what does the heating of it do to the atoms?what does the cooling of it do to the atoms?what makes tempered steel so strong compared to untempered steel?
- You can't temper all steels. Generally the material must be a high-carbon or tool steel. Different alloys temper differently, and tempering is usually done to get a specific set of characteristics, so you must know what you are working with and use the right methods and temperature. If you do it wrong, the material may be hard but too brittle for the purpose or have other issues. It can be simple, such as heating to a dull red, carbonizing the surface (use an acetylene rich flame until it blackens the surface) and oil quenching. Do that to a piece of tool steel (like a screwdriver) and it will case (surface) harden it to the point you can't scratch it with a file. Tempering changes the way the molecular structure in the metal is linked and oriented.
- Q: Can steel coils be coated with anti-corrosive substances?
- Yes, steel coils can be coated with anti-corrosive substances to protect them from rust and corrosion.
- Q: What are the safety considerations when handling steel coils?
- When handling steel coils, there are several safety considerations that should be taken into account. Firstly, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, safety glasses, and steel-toed boots. This protective gear helps to minimize the risk of injuries from sharp edges, flying debris, or accidental contact with the coils. Secondly, it is important to have a clear understanding of the weight and dimensions of the steel coils being handled. Steel coils can be extremely heavy, and improper lifting techniques can result in back strains, muscle pulls, or even more severe injuries. Therefore, it is crucial to use proper lifting techniques, such as bending the knees and keeping the back straight, or utilizing lifting equipment like cranes or forklifts when necessary. Additionally, steel coils can be unstable and prone to rolling or shifting during handling. To prevent accidents, it is crucial to secure the coils properly before moving or stacking them. This can be done by using appropriate lifting attachments, banding the coils together, or utilizing racks or other storage systems specifically designed for steel coils. Furthermore, it is important to be aware of the potential hazards associated with the steel coils, such as sharp edges, oil or grease coatings, or even damage to the coils themselves. It is essential to inspect the coils for any abnormalities or defects before handling them, as well as ensuring that they are stored in a safe and stable manner to prevent accidents. Lastly, proper communication and training are essential when handling steel coils. It is crucial to establish clear communication channels between workers to ensure that everyone is aware of their roles and responsibilities. Additionally, providing training on safe handling techniques, potential hazards, and emergency procedures can help minimize the risk of accidents and injuries. In conclusion, when handling steel coils, it is important to wear appropriate PPE, use proper lifting techniques, secure the coils properly, be aware of potential hazards, and ensure proper communication and training. By following these safety considerations, the risk of accidents and injuries can be significantly reduced.
- Q: Can one assume that stainless steel that can be hardened is magnetic?
- actually stain less steel is mainlly three first one is austenitic, 2nd one is ferritic, and 3rd is martensitic. These three types of steels are identified by their microstructure or predominant crystal phase. Austenitic. Austenitic steels have austenite as their primary phase (face centered cubic crystal). These are alloys containing chromium and nickel (sometimes manganese and nitrogen), structured around the Type 302 composition of iron, 18% chromium, and 8% nickel. Austenitic steels are not magnetic and not hardenable by heat treatment. The most familiar stainless steel is 304 containing 18-20% chromium and 8-10% nickel. Ferritic. Ferritic steels have ferrite (body centered cubic crystal) as their main phase. These steels contain iron and chromium. Ferritic steel is somewhat magnetic, less ductile than austenitic steel, and is not hardenable by heat treatment. Martensitic. Martensitic steels have orthorhombic martensite as their main phase. Martensitic steels are low carbon steels. They are magnetic, and may be tempered and hardened. Martensite gives steel great hardness, but it also reduces its toughness and makes it brittle. If you ran around the house with a magnet, checking on the items you know are stainless steel, you would probably find that cookware and flatware are not magnetic, but cutlery might be slightly magnetic.
