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.
5.Others:vending machine; game machine; etc.

- Q: I noticed a friend's appliances are not magnetic, and mine are. Both are stainless steel. Are there two types of stainless steel or something? Thanks
- Some stainless steel are magnetic and some aren't. The real high grade stainless steels aren't magnetic.Stainless is just regular steel with varying degrees of nickel and chromium alloys mixed in the batch. The more nickel and chromium the less likely to be magnetic. A lot of stainless exhaust pipes and barbecue grills claim to be stainless, and yet they still rust and tend to be magnetic. They must use the bare minimum of nickel and chromium in the melted batch just to claim the title of stainless steel. Nickel and chromium are quite expensive and they are what gives the steel the anti-corrosion and extreme hardness characteristics along with loss of magnetism of the steel. If you have stainless steel that is magnetic , it is a good sign it is stainless steel that barely meets the criteria of true stainless steel.
- Q: Are steel coils used in the packaging industry?
- Yes, steel coils are commonly used in the packaging industry for various purposes such as securing and stabilizing loads, protecting products during transportation, and providing structural support to packaging materials.
- Q: Can steel coils be customized in terms of size and shape?
- Yes, steel coils can be customized in terms of size and shape.
- Q: I'm buying a new set of steel plugs.I've heard things about streched ears and cold weather not being to good. do you think it would be bad to be wearing steal plugs?
- Personally, okorder They are spot on for sizing, they do customs, and amazing quality like i have never seen before and I have been through a lot of plugs. Hope this helps :)
- Q: Can steel coils be coated with copper?
- Yes, steel coils can be coated with copper.
- Q: Maybe it is obvious. But i have thought alot about it.I thought steel at a cool temperature was unbreakable. I am not one for science or physics or engineering (i am a political science major). But i don't understand why the planes that struck the world trade center on 9-11 didn't just dent the side and fall,How did the place break the steel? Was it the velocity? Is steel easily broken?I realized that i wasn't taught how the planes broke the steel, and that no one ever asked. I searched the web and i couldn't find the answer or even anyone who had asked the question before.(i don't care about conspiracy theories, i just want scientific facts)
- 1 nothing is unbreakable! 2 it is a question of velocity not that the plane was going very fast but! the difference between an explosion and a detonation is if the flame front is faster or slower than 1000 meter per second If you burn Hydrogen it burns fast, more than 1000 meter per second at that speed a plastic pen like those you use every day will puncture through a steel 2X4 used in modern building walls it is not thick steel but it is still steel! and the plastic piece is hardly deformed Those talking about aviation fuel... this is long, very long after the fact Guru
- Q: How does the surface finish of steel coils affect their performance?
- The surface finish of steel coils greatly affects their performance. A smooth and uniform surface finish enhances the coil's corrosion resistance, durability, and ability to resist wear and tear. It also improves the coil's ability to form and join with other materials, making it easier to work with during manufacturing processes. On the other hand, a rough or uneven surface finish can lead to decreased performance, as it can negatively impact the coil's ability to resist corrosion, reduce its overall strength, and potentially cause issues during processing and handling. Therefore, ensuring a proper surface finish is crucial in optimizing the performance and lifespan of steel coils.
- Q: What are the common coil edge finishes?
- The common coil edge finishes include mill edge, slit edge, and deburred edge.
- 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: How are steel coils used in the production of storage tanks and silos?
- Steel coils are used in the production of storage tanks and silos as they provide the necessary structural strength and durability required for these storage structures. The coils are formed, cut, and welded into the desired shape to create the walls and roofs of the tanks and silos. This ensures that the storage vessels can withstand the weight of the stored materials and any external forces exerted on them.
