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 Z80 for Construction Roofing Constrution
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: 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!
- That is an ENORMOUS subject that won't fit in this little box. Run an internet search on steel making. Essentially, steel is an alloy of iron and other metals chosen to give it the desired properties. These metals usually come from ores that are extracted from the earth. Actually, iron has too much carbon for most steel making purposes, and the carbon must be burned off. Iron is melted in a blast furnace, and oxygen is used to burn off the excess carbon. Then the molten metal is mixed with molten alloy metals and poured into molds to make ingots, which are blocks of steel of a size convenient for handling. Steel can also be made by re-melting scrap metal and adjusting the amounts of various adulterants or alloy metals at molten temperatures. The ingots are taken to rolling mills to be shaped into rods, pipes, sheet metal, and structural shapes. Molten iron and steel can also be poured into molds to produce complex shapes.
- Q: I have been thinking of buying a knife that says it has damascus steel. The reason for the question is that many people told me that damascus steel does not exist anymore, and that damascus nowadays is fake. Is this true???
- damascus steel it says is made from ore containing either tungsten or vanadium, although most tools I've seen are made from chrome vanadium, it wouldn't be hard in this day and age to get the proper material. Although it DOES say in wikipedia that apparently the technique died out a long time ago due to shortage of the ore. Then it talks about reproduction attempts. So theoretically, yes, it could be the deal deal. But it does refer at the bottom about damascend steel which is made with a different technique, you could be buying one of those. NEXT TIME JUST LOOK UP THE ARTICLE YOURSELF AND READ IT
- Q: I was curious to what type of steel I should get if I wanted something that kept its edge longer than 154cm but is still just as stainless. I don't know much about knife steels inform me please?
- 154cm is a very good knife steel, the problem is in the heat treating. Stainless should be cryo treated to get all it can offer. That being said, if you really want to drop some coin, look at getting one made from CPM 440V. Stainless isn't as strong as carbon but on a smaller knife works well. You might also look for D-2 Tool steel. There are factory knives that are made of that.
- Q: Why do we galvanise steel? Galvanised steel is steel coated with zinc.
- The coating of zinc inhibits rust. First of all the zinc does not oxidize a readily as iron (steel). If the zinc coating gets scratched it still protects the exposed iron. When the zinc and exposed iron get wet they behave like a battery. Electrons flow from the zinc layer to the iron layer. The extra electrons in the iron layer replace any that might be lost to oxidation and help keep the iron metallic. Of course now the zinc oxidizes faster so eventually all of the metallic zinc is removed and the iron is unprotected and will rust. The fact that the zinc doesn't have to cover the steel is shown in another process. To protect the steel hulls of ocean going ships a block of zinc is attached to the bottom. The electrical circuit behaves as described above. When the zinc block has dissolved they just attach another one. If they keep this up the hull of the ship remains corrosion free. A tin coating on steel (as in a tin can) works just the opposite. When the tin is scratched the electrons flow from iron to tin so the iron rusts faster than it would have with no tin.
- Q: How do steel coils contribute to energy efficiency in lighting?
- Steel coils do not directly contribute to energy efficiency in lighting. Steel coils are typically used in the manufacturing of various electrical and electronic appliances, including lighting fixtures. However, the energy efficiency in lighting primarily depends on the type of light source used. The energy efficiency of lighting is typically determined by the type of light bulb or fixture used, such as incandescent, fluorescent, LED, or halogen. Each of these light sources has different energy consumption characteristics. Steel coils, on the other hand, are primarily used for structural support, heat dissipation, and protection in lighting fixtures. They are not directly involved in the energy efficiency of the lighting system. However, steel coils can indirectly contribute to energy efficiency in lighting by providing strong and durable support to the lighting fixtures. This allows for reliable and long-lasting installations, minimizing the need for frequent maintenance and replacements. A well-supported lighting system ensures optimal performance and reduces any energy wastage or inefficiencies that may arise from loose or unstable fixtures. Additionally, steel coils can also be utilized in the manufacturing of reflectors or housings for lighting fixtures, which can help enhance the overall efficiency and distribution of light. By effectively reflecting and directing the light output, the utilization of energy and illumination can be optimized, reducing any potential energy waste. While steel coils themselves do not directly impact the energy efficiency of lighting, their use in the construction and support of lighting fixtures can indirectly contribute to a more energy-efficient lighting system.
- Q: I bought my Gerber Scout for 29 bucks at the local Walmart a couple months ago, and so far it's performed better than any of my previous knives (a couple of low quality Bucks, and a Winchester). However, my friend just bought a 50 dollar Buck knife and I absolutely love it, so I'm debating trading mine in and pitching in a bit of cash for the same kind.What troubles me is the fact that everybody seems to be bashing 440A steel. I hear a lot of bad things about it; how it is soft, chips easy, dull quickly, etc. How bad is 440A steel really, and would it be worth trading in my Gerber plus about 30 cash for a Buck Vantage Pro? Apparently the Vantage Pro uses S30V steel, so is it really that big of an upgrade, from 440A to S30V? Thank you.
- 440 steel is fine for most knives, but there are better quality steels out there for specialized uses. If you like the knife you have, don't worry about what other people say. If you like the new knife more, trade for it. Sometimes I question why people have to ask so many questions about what's better than what.

- Q: like the steel industry and the effects it had on industrial growth, 10 points!
- The single most important important advance in steel production was learning to accurately control carbon content. This was done through the Bessemer Process in which air was blown through molten iron to burn out impurities and excess carbon. Low carbon iron (wrought iron) could be easily worked into shapes. Medium carbon iron could be cast into useful and durable shapes. High carbon steel could be used for structural uses (beams and girders). Adding alloys such as nickel and silicon could produce very tough steels and steels resistant to rust. Adding vanadium to steel engine parts allowed Ford to produce finely machined engines in huge numbers with existing machinery.
