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: Hello,is it possible to divide an alloy in its own elements? I am particularly interested in Stainless Steel, which is made of Nickel, Chrome and Iron. Do you have an idea of where can I find some more information (blogs, reviews, sites or books)?Thanks for your help
- Yes it is possible to recover individual elements from an alloy such as stainless steel, but not easy. Look up etching of stainless steel on google. This same etching solution will completely dissolve stainless steel. These solutions are strong acids such as H2SO4 and HNO3 so safety goggles and good ventilation are absolutely required. Once the metal has been dissolved, then you would need to use a qualitative analysis scheme to precipitate out the different metals one at a time as compounds, then do additional reactions to recover the metallic elements.
- Q: I have a new stainless steel trash compactor under a butcher block counter. We refinished the countertop, but unfortunately the person who did it wasn't careful with the orbital sander and sanded the top edge of the stainless steel compactor door, ruining the finish. The sander marks are not deep - just surface scratches - but they are unsightly. Is there any way to restore the finish to the stainless steel without having to buy a new door?
- How To Refinish Stainless Steel
- Q: What are the common methods of protecting steel coils from corrosion?
- Common methods of protecting steel coils from corrosion include applying a protective coating, such as zinc or paint, using corrosion inhibitors, storing coils in a controlled environment with low humidity, and implementing proper handling and packaging techniques to prevent moisture exposure.
- Q: I would like to know if steel is basically a very dense crystal, or if it is a different atomic structure
- Steel is made of billions, trillions of very small crystals. This is true of most metals. In order to see the crystal structure of steel, you usually need to cut a sample of it, grind and polish the cut face smooth, then etch the steel with a mixture of nitric acid and alcohol. Without polishing and etching the crystals aren't visible- it just looks like smooth solid metal. Also, in most cases the crystals are small enough that you need a microscope to see them clearly after etching.
- Q: How are steel coils processed for different finishes?
- Steel coils can be processed for different finishes through various methods. One common process is called coil coating, where the steel coil is cleaned, primed, coated, and cured to achieve a desired finish. This process includes removing any contaminants from the surface of the coil, applying a primer to enhance adhesion, and then coating it with a specific paint or coating material. The coated coil is then cured at high temperatures to ensure proper adhesion and durability. Another method for processing steel coils is through galvanization. In this process, the steel coil is coated with a layer of zinc to protect it from corrosion. This can be done through hot-dip galvanization, where the coil is immersed in a bath of molten zinc, or through electro-galvanization, where a thin layer of zinc is electroplated onto the coil. The galvanized finish provides excellent corrosion resistance and can be further processed to achieve different aesthetic finishes. Additionally, steel coils can be processed for different finishes through various surface treatments. This may involve processes such as pickling, where the coil is treated with an acid solution to remove scale and impurities, or mechanical treatments like brushing or grinding to achieve a desired texture. These surface treatments can be followed by applying a protective coating or paint to enhance the appearance and durability of the coil. Overall, the process of achieving different finishes on steel coils involves a combination of cleaning, coating, curing, and surface treatments. The choice of specific methods depends on the desired finish and the intended application of the steel coil.
- Q: What is the process of pickling and oiling steel coils?
- To ensure the quality and protection of steel coils, a series of steps are undertaken in the process of pickling and oiling. The first step involves pickling, wherein impurities and scale are removed from the surface of the steel coil. This is achieved by immersing the coil in an acid bath, such as hydrochloric acid or sulfuric acid, which effectively dissolves any oxides, rust, or contaminants present on the surface. This step is critical as it readies the steel for further processing and safeguards against potential defects or corrosion. Following pickling, the steel coils are rinsed with water to eliminate any residual acid and then dried. Once they are clean and dry, a layer of oil is applied to provide temporary corrosion protection and lubrication during subsequent handling and transport. The oil coating acts as a barrier, preventing rusting or oxidation before the steel undergoes further processing or is utilized in various applications. The oiling process can be executed through various methods. One common approach is to apply the oil using a roller or brush, ensuring an even coating across the entire surface of the coil. Alternatively, the coils can be passed through a bath or spray chamber where the oil is administered. The choice of oil depends on the specific requirements of the steel and its intended use, with options ranging from mineral oil and synthetic oils to specialized rust-preventive coatings. Once the oiling process is complete, the steel coils are typically stacked, wrapped, or packaged for storage or transportation. It is crucial to handle the coils with care to avoid damaging the oil coating and compromising the corrosion protection it provides. Overall, the pickling and oiling of steel coils are indispensable steps in the steel manufacturing process. They ensure the quality, cleanliness, and protection of the steel, thereby prolonging its lifespan and enhancing its performance in various applications.
- Q: I have two guitars, a nylon stringed classical, and a steel stringed acoustic, I find the nylon strings easier to play, but doesn't have as good of sound as the steel stringed, and when I play with the steel strings, it really hurts my fingers, and if I play just a little bit, it feels like the high e string is going to cut my finger. Are the strings too high? What can I do to make the steel strings easier to play?
- find an online tuner and tune the strings to the tuning you want. trust me, guitar hurts your fingers after a while. but your skin gets used to it's, it's what ever.
- Q: Can steel coils be cut?
- Yes, steel coils can be cut using various methods such as shearing, sawing, or laser cutting, depending on the thickness and type of steel.
- Q: Hello. right now i have been playing electric and acoustic guitar for 6 years. I currently became very interested in learning the pedal steel guitar. I will be teaching myself so is it really hard to learn? Are there a lot of songs online that could give me tabs? Basically im asking if it is worthwhile to spend a lot of money. I dont want it if there are only 3 songs im gona learn. im up for the challenge im just curious how hard it was to learn. thanks for your help.
- The okorder /... Beware of eBay deals unless you know what you're buying. To start, you should get a 10-string single neck with 3 pedals and 4 levers. Some of the student models don't have as many levers and aren't capable of all the changes you need. Stay away from the ShoBud Maverick...you'll outgrow it in a couple of months. Often it makes more sense to buy a used professional model...you'll eventually need one, and they hold their value better than a student model. You'll also need a volume pedal, bar, thumb and finger picks. For now, your guitar amp will be ok. Playing the guitar: There are several tunings and lots of different combinations of levers, but the basic guitar is a 10 string E9 tuning. It's almost an open E but with a few extra notes. The pedals and levers raise and lower the pitch of selected strings. Chord changes are made by moving the bar and pressing pedals and levers. The volume pedal helps you swell and sustain notes. Steel has it's own unique tablature which reflects all these changes. If you have any other questions, feel free to email me or just join the PSG forum and ask there.
- Q: How are steel coils used in the manufacturing of transmission shafts?
- Steel coils are used in the manufacturing of transmission shafts by being converted into cylindrical shapes through a process known as coil winding. These coils are then cut, shaped, and machined to create the desired dimensions and specifications for the transmission shafts. The high strength and durability properties of steel make it an ideal material for transmission shafts, ensuring efficient power transmission and overall performance of the machinery.
