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.
Applications of Prepainted Rolled steel Coil for Construction Roofing
1. Construction and building: roofing; ventilating duct; handrail; partition panel;etc.
2. Electric appliance: refrigerator; washing machine; refrigerator; DVD;etc.
3.Transportation: oil tank; road sign; etc.
4.Agriculture:barn; etc.

- Q: Ok I have a neodymium magnet, stuck to my fridge holding a old bottle cap opener for my beer it works fine. At the local rummage sale there was a beautiful cap opener my freind was selling for $0.25 she said had never beenUsed it was like 40 years old it is made a stainless steel. The magnet will not stick to it. I don't understand this looked this up and certain steels are not magnetic, I tried a experiment with my compass it don't point north as should it follows the bottle opener as I move it around it. If not magnetic why is this happening? Also tried placing near another neodymium magnet with a pull of about 200 lbs. Not I tiny bit of attraction to the metal. If so why is the tiny magnet in the compass attracted to it. But not a huge powerfull magnet.
- That's interesting that it caused deflection in the compass. A lot of stainless steels may be SLIGHTLY magnetic, because they have small amounts of ferrite or alpha-iron in them. Ferrite is one of the crystal phases of steel. It has a body-centered cubic (BCC) structure and it's responsible for the magnetism of ordinary steels. Adding certain elements like nickel, manganese, or molybdenum, changes the crystal structure of the steel to a face-centered cubic (FCC) structure, which is NOT magnetic. This crystal phase is known as Austenite or gamma-iron. However most iron alloys contain some impurities that may cause the steel to be not completely transformed into the FCC austenite phase, small areas remain as ferrite.
- Q: What are the safety regulations for handling steel coils?
- The safety regulations for handling steel coils include wearing personal protective equipment (PPE) such as gloves, safety goggles, and steel-toed boots to protect against injuries. Employees should be trained on proper lifting techniques and use mechanical aids whenever possible to prevent strains and sprains. The storage area should be well-organized, with coils stacked securely to prevent them from falling. Regular inspections and maintenance of equipment, such as cranes or forklifts, should be conducted to ensure safe operations. Additionally, awareness of potential hazards, such as sharp edges or protruding nails, is crucial to prevent cuts or puncture injuries.
- Q: .Yea, so I just saw the old Conan movie with Arnold. Good movie, but I still don't get it. What IS the riddle of steel???I get that like from the begining Conan's dad is like telling him a story about Crom and giants, and people got steel once Crom killef the giants. Then, later on in the movie Conan's talking to his lil' asian homie, and Conan tells him that when he dies... he'll go before Crom, and Crom will ask him what the riddle of steel is, and if he doesn't know it he'll get kicked out of barbarian heaven!But, what is the riddle of steel???C'mon guys... I want to in to barbarian heaven! LolBut, seriously though... what us it???.

- Q: I heard that titanium isn't the most hypoallergenic metal because it is treated and the chemicals can cause an allergic reaction. I also heard that surgical steel is the best because it is what is used in surgery and in hip replacement implants etc. Is this correct?I've always heard that titanium is best, but now I'm curious because surgical steel is much cheaper than titanium which can be expensive.Thanks
- Implant grade titanium is much better than surgical steel. The nickel content in it (which is what alot of people are allergic to) is virtually non-existant. Though most people with a nickel allergy are fine with surgical steel too, its too small for most people to react to. But the odd few people do. Its the same with everything. Good surgical steel is probably better than cheap titanium. But implant grade ti will beat it hands down. And ti is alot stronger, and is also used in surgical impants and as replacement bits too. But a big lump of titanium hip is going to be expensive. If you're not allergic to steel, theres little reason for the extra cost, especially if it's likely to outlive you. Niobium has no nickel in at all. But that really is expensive, and I've never seen any threaded. Any particular reason why you ask? ----- Piercing-wise titanium will be better than steel. Unless they carry some not so great ti. You should be fine with steel though.
- Q: How are steel coils processed for stamping or forming?
- Steel coils are typically processed for stamping or forming by first uncoiling them and then flattening or leveling them to remove any curvatures or distortions. After that, the coils are fed into a stamping or forming machine, where they undergo different processes such as cutting, bending, or shaping to achieve the desired final product.
- Q: What are the different methods of heat treatment for steel coils?
- Steel coils can undergo various heat treatment methods, each offering unique benefits and applications. One method is annealing, where steel coils are heated to a high temperature and gradually cooled in a controlled environment. This relieves internal stresses, enhances ductility, and refines the grain structure, resulting in softer and more machinable steel. Another method, normalizing, is similar to annealing but involves a faster cooling process. It aims to refine the grain structure and achieve uniform hardness throughout the coils. Normalizing also eliminates residual stresses and improves mechanical properties. Quenching and tempering is a two-step process that begins with heating the coils to a high temperature and rapidly cooling them in a quenching medium like oil or water. This creates a hard and brittle phase called martensite. To enhance toughness and reduce brittleness, the coils are reheated to a lower temperature and held there for a specific duration, a process known as tempering. Tempering helps decrease internal stresses and increase ductility and toughness. Case hardening is another method used to increase the surface hardness of steel coils while maintaining a soft and ductile core. This involves heating the coils in a carbon-rich atmosphere, allowing carbon to diffuse into the surface layer. The result is a hard outer layer, known as the case, while the core retains desired mechanical properties. Stress relieving is performed by heating the coils to a specific temperature and holding them there for a sufficient time. This minimizes residual stresses from previous manufacturing or heat treatment processes. Stress relieving improves dimensional stability, reduces the risk of distortion or cracking, and enhances overall performance. The choice of heat treatment method depends on desired properties, intended application, and specific requirements of the end product. Each method has its own advantages and can be customized to achieve the desired balance between hardness, toughness, ductility, and other mechanical properties.
- Q: Does anyone know what colour steel is?How hard steel is?The density of steel?Conductivity of steel? (Heat and electricity)Reactivity of steel?Melting and boiling points of steel?And the malleability and ductility of steel?Ive looked all over the net and i cant find anything. Can someone please answer these questions or give me a website?THANKS!
- It's going to be made from a Shock Resisting Tool Steel ideally. Those steels average .50-.55 % carbon. They combine the ability to withstand repeated blows with excellent hardenability and toughness.
- Q: What brand steel tapes are of good quality?
- Personal feeling is also good for the Great Wall Seiko tape, upstairs several estimates are the production of steel tape manufacturers, of course, that their goods well. Our unit now buy all the Great Wall Seiko goods, said the tape is good, not because it is so durable
- Q: How are steel coils used in the production of automotive components?
- Steel coils are used in the production of automotive components as they are rolled into flat sheets and then further processed to create various parts such as body panels, frames, and chassis. These coils provide the necessary strength and durability required for automotive applications, ensuring the safety and performance of vehicles.
- Q: i have a pocket knife that is stainless steel that my mom found in the parking lot and i am wondering if oxygen peroxide will rust it? and if it dose is there something else i can use to get rid of the rust?
- Stainless steel does not rust, but It can get dulled. Oxygen peroxide will not hurt it.
