Structure of Prepainted Rolled steel Coil for Construction Roofing

 Prepainted Rolled steel coil for Construction Roofing use

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:what are some advantages of stainless steel?
It is great for knives because it stays chromed looking without rust. The steel is very hard so holds an edge for a long time. If it contains enough nickel it also is not magnetic, which some applications need this trait It is used for exhaust pipes in good cars, because it doesn't corrode from exhaust like common steel will, so the exhaust pipes last very long. Stainless is used for sinks, ovens, and kitchen appliances because it holds a shine, is very durable , doesn't crack or get burn holes like plastic would. It doesn't rust and is easy to clean and has a good color. It is used on exterior building panels for the same reason , plus it adds the same structural strength as regular steel without the maintenance of painting and rust removal. It is great for pans because you can scrub it without scraping it and it conducts heat well and cleans easily because the surface is smooth and hard So it has the same advantages of strength and fabrication as regular steel, without the downside of rust and ugliness. More cost (it contains chromium and nickel which are expensive) and harder to weld is two of it's shortcomings
Q:Why cold rolled stainless steel sheet is lower than cold rolled stainless steel coil?
Hello! The reason is: 1. cold rolled flat plate is Kaiping;2. cold-rolled plates are negative tolerances.
Q:Is steel lighter than iron?
For the same volume of part, like a cubic inch, the weight is very close. If you base the comparison on strength, like a bar strong enough to hold XXX pounds, then the forged bar will be lighter, smaller still hold the weight.
Q:Movies- Conan: What is the riddle of steel?
This Site Might Help You. RE: Movies- Conan: What is the riddle of steel? . 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...
Q:Magnet will not stick to stainless steel?
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:Does steel make its own static electricity?
If you sprinkle iron filings near a bar magnet (on paper, etc.) the filings will try to line up with the magnetic field (because iron atoms behave like tiny magnets). Bringing the compass near steel (mainly iron with a little carbon) will cause the iron to try to align with the magnet of the compass needle, however, because the needle is free to swing it also aligns with the magnetic field set up between the needle and steel. Any static electricity would have nil effect on the magnetic field.
Q:What minerals are stronger then steel?
Mineral ≠ metal Strong ≠ hard Even after you learn what the words mean, the only straight answer is still Look and see.
Q:Why can aluminum and steel casings not be used for reloading?
Some Blazer/CCI loaded ammo comes with aluminum casings, it is easy to tell because they have a very dull finish compared to the nickel. These cases are not safe to reload. There is also Wolf brand from Russia that has a steel casing, it looks laqured and it may or may not be able to be reloaded.
Q:i need help about stainless steel?
Weathering steel will rust, but the rust will be adherant and not flake off and be replaced by new rust. Therefore once it rusts it will pretty much stop rusting any more. One (severe) down side is that anything around it will be streaked with rust stains and it will look awful. Some bozo with the Texas Department of Transportation designed a number of freeway interchange overpasses here in Houston using Cor-Ten steel and all of the concrete supports are streaked with red rust stains and it looks like hell. Cameron built an office building here in Houston with a Cor-Ten facade and it is streaked with rust too. They should have gone ahead and spent the money and painted them, but they didn't.
