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:why is ships made of steel?
also add to answers above (now below), zincs are mounted on the hull and shaft to draw the electrolysis to them instead of the hull and are easily replaced by a competent diver
Q:Which one is better to start? Steel or Acrylic tapers?
steel because they dont get that infected also they sre easier to put in. but they do get cold in the winter
Q:Is steel in spacecraft Ulysses?
Reach the core of the sun? No material can even get past the corona of the sun, where did you hear Ulysses went to the core? The spacecraft Ulysses orbits the sun at about 5 au. that's 5 times the earths orbit.. Steel is used instead of Iron because steel is much stronger and therefore you can use smaller 'bolts' to accomplish the same thing, reducing the weight. As far as most structures are concerned steel is better than plain Iron in every category. So Iron is worse i guess.
Q:Where do I need hot galvanized steel coils and color coated rolls?
In industrial or coastal areas, due to the influence of sulphur dioxide or salt in the air, the corrosion rate is accelerated and the service life is affected. In the rainy season, the coating has been soaked by rain for a long time, or the temperature is too large and easy to dew. It will be corroded quickly and the service life will be reduced. A building or building made of colored coated steel plates, often with a long service life when washed by rainwater, otherwise affected by sulfur dioxide, gas, salt, and dust. Therefore, in the design, if the roof slope is greater, the more difficult to accumulate dust and other dirt, the longer the service life; for those areas or parts that are not often washed by rain water, should be regularly washed with water.
Q:Steel reinforced armor.?
I don't think that would work. First off, there's not enough carbon in steel - even very high carbon steels are only about 2% carbon. Second, the iron atoms in steel form a crystal lattice, in the shape of a cube, with another iron atom in the middle of the cube. Each cube is about 0.3 nm per side. Carbon atoms work their way into the crystals and displace the iron atoms. But a carbon nanotube is around 1 nanometer in diameter - that's 3 times as big as the iron lattice! So a nanotube wouldn't fit. One thing you might do, however, is make a composite - mix the materials together on a scale a little bigger than the atomic scale that the iron and carbon mix to make steel. Just like a carbon fiber bicycle frame or ski pole is strands of carbon (much bigger and not as strong as nanotubes) held together with epoxy, you could hold nanotube strands together with metal. Not sure it would be good for armor, but if you can figure out a way to do it, I'm sure someone will come up with a use for it!
Q:What knife steel will last the longest?
Most okorder.com/
Q:Will this steel rust?
carbon will rust.. stainless doesn't rust unless it touches carbon so its definitely not stainless. Since its only 1.7% its extremely unlikely that it will rust unless you leave it outside for extreme long periods of time. Either way you should take care of it. Put it in the garage or something but you don't have to dry it after every use.
Q:High Speed Steel Information!?
wikipedia: High speed steel (often abbreviated HSS, sometimes HS) is a material usually used in the manufacture of machine tool bits and other cutters. It is often used in power saw blades and drill bits. It is superior to the older high carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high speed steel. At room temperature, in their generally recommended heat treatment, HSS grades generally display high hardness (above HRC60) and a high abrasion resistance (generally linked to tungsten content often used in HSS) compared to common carbon and tool steels. see reference for more info .
Q:Environmental concerns for a steel works factory?
Q:Is stainless steel magnetic?
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.
