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: How are steel coils used in the manufacturing of storage shelves?
- Steel coils are used in the manufacturing of storage shelves by being cut and shaped into the desired size and design. The coils are typically processed through a roll forming machine which bends and molds the steel into the required shape for the shelves. This process allows for high efficiency and precision in creating uniform and durable storage shelves.
- Q: were iron age weapons made of steel?
- Even in very early iron, a small amount of steel was produced by carburization, where the iron picks up carbon by laying in hot coals before quenching. This produces a thin layer of steel on the surface of the iron. By about 300 BC Damascus steel was being produced by the crucible method on the Indian subcontinent, and the Romans used steel from Noricum. In the first century BC the Chinese were melting cast iron and wrought iron together to make steel.
- Q: i always have eaten rolled oats and i have never tried steel cut oats. what are your opinions on them for oatmeal and which do u like better?
- Steel cut oats, much better texture. You can prepare them overnight in a mini-crockpot with raisins, brown sugar, nuts or anything you like in your oatmeal. You can also put steel cut oats and all your favorite oatmeal toppings in a stainless steel thermos with boiling water overnight. Either way it will be hot and ready to go in the morning. Have a great day!!
- Q: Are steel coils used in the packaging industry?
- Yes, steel coils are commonly used in the packaging industry for various applications such as securing and protecting products during transportation and storage. The strong and durable nature of steel coils makes them ideal for packaging heavy or bulky items, providing stability and preventing damage.
- Q: What are the different methods of coil blanking for irregular shapes?
- Coil blanking for irregular shapes can be achieved through various methods. Among these methods, one commonly employed technique is laser blanking. By utilizing a high-powered laser, the shape is directly cut from the coil with exceptional precision. This method proves especially effective for intricate shapes, minimizing wastage. Another approach is water jet blanking, where a forceful stream of water mixed with abrasive particles is employed to cut the shape from the coil. Water jet blanking is particularly suitable for thicker materials or situations where heat sensitivity is a concern. Additionally, die blanking involves the utilization of a die to stamp out the desired shape from the coil. This method is frequently applied in large-scale production runs and can be automated for improved efficiency. Lastly, plasma blanking utilizes a plasma torch to cut the shape from the coil. It is commonly employed for thicker materials or situations requiring high cutting speeds. The choice of coil blanking method for irregular shapes is dependent on factors such as material thickness, shape complexity, production volume, and desired precision. Each method possesses its own advantages and limitations, necessitating careful selection to achieve optimal results.
- Q: im writing a book.-how is steel made? like, from what natural resources?-is there a type of factory that just prouduces steel to then be made into the various things made out of steel? if so, what kind of company might that be?-what is the first stage of steel, like, right after the other....ingrediants......are mixed, but before it is shaped into whatever its destined to be?thank you so much, i really appreciate it!
- Steel is made from iron with some amount of carbon added in- in essence, it is an alloy. A steel factory is a factory that makes steel. It is often sold in bars or in ingots, but many factories also produce steel in prefabricated shapes. The first stage of steel involves molten iron, which then has carbon added to it, eventually becoming molten steel, which hardens into steel.
- Q: What does "steel roll number" mean?
- The coil numbers in the steel industry are generally applicable to rolled round steel bars. A coil of steel has a specified length and weight. Different rolls have different volumes
- Q: How are steel coils used in the production of metal ductwork?
- The production of metal ductwork relies heavily on steel coils. Typically constructed from high-quality steel, these coils serve as the primary raw material for manufacturing ductwork. To begin the process, the steel coil is unwound and then cut into specific lengths based on the required dimensions of the ductwork. These lengths are then shaped using specialized machinery, such as roll formers or bending machines, to achieve the desired form. The steel coils are essential in providing the necessary strength and durability to the ductwork, ensuring its ability to withstand the pressure and environmental conditions it may encounter during operation. Additionally, the composition of the coil allows for easy fabrication and customization, enabling manufacturers to produce ductwork in various shapes and sizes to meet specific project requirements. Moreover, steel possesses inherent properties that make it an ideal material for ductwork. Its resistance to corrosion and fire makes it highly desirable. Steel coils can also be coated with protective layers, such as galvanized or stainless steel finishes, to further enhance their longevity and performance. This added protection ensures that the ductwork remains intact and functional, even in harsh environments or when exposed to corrosive substances. In conclusion, steel coils are indispensable in the production of metal ductwork as they provide the necessary raw material for fabrication. Their strength, durability, and customization capabilities make them a crucial component in the manufacturing process, resulting in reliable and long-lasting ductwork systems.
- Q: I am trying to clean up a stainless steel back splash and some kitchen appliances that have brown spots that look like rust spots. I was able to remove most of them with stainless steel cleaner but does anyone know any tricks?

- Q: Does steel have a valence number and if so, what is it?
- Steel is a mixture, so it doesn't have any valence number. On the other hand, all of the components of the steel mixture are in their elemental forms, so all the various valences are zero.
