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 good knife steels?
Buying good knifes now-adays is very difficult as most steel is made abroad and the quality is not the same as it used to be, British steel made in Sheffield used to rule the world but alas no more! so basically you get what you pay for, so you must be prepared to part with a substantialal amount of your hard earnt cash to get the best.
Q:Can a bear bend steel?
depends on the steel thickness and positioning. frm your question I'm guessing you're not really well versed in steel framing or use... im guessing whatever you build, a bear can destroy. if i was to build it not even 100 bears can destroy it. it doesn't require much steel, it's just about bracing the positing of steel and some design.
Q:Are cold steel swords durable?
Yes. Cold Steel is a great company with a quality product, and I've always been happy with their work. Their katanas, while not made in the traditional method, are heavy duty carbon steel and should handle abuse well. I'd recommend them based on my experience with other Cold Steel products.
Q:Question about whetstones and honing steels.?
You're not supposed to use the whetstone alone. It leaves a burr, which the steel removes. If you google using a whetstone, you'll see plenty of info. It is possible to use a finer stone in place of the steel.
Q:Permanently expanding steel?
You can calculate the maximum reversible strain, for elastic loading as follows: You need to look up the yield strength (for that particular type of steel). Divide this yield strength by the elastic modulus of steel (also called Young's modulus). That gives you the strain at the onset of yielding, the maximum you can strain the steel fibers before crossing the point of no return. If you are interested in the strain until failure, you need to take tensile test measurements. Seldom do people document an equation to model the non-elastic portion of the stress-strain curve of the specimen, because seldom do we design systems to operate with materials which yield. We want systems which only deform reversibly and elastically. This means you need to perform an experiment to find what you are actually desiring to know.
Q:Steel sole combat boots?

Q:What type of metal is T10 tool steel?
Carbon Tool Steel usually in the form of forged bar stock. Steel Grades for tool steel can be any of the following (depending on the application) T10/1.1645 SK3/SK4/W1A-91/2/ TC105/y10/1880/BW1B T10A/1.1545/y10A/1880 Standards are published by: DIN, JIS, ASTM, AISI, BS, SS, ISO, TOCT, GB Doug
Q:Steel mine question help!!!?
There's no such thing as a Steel mine - steel is made from various raw materials (and now recycled metals). These materials may be mined separately and then combined at a steel mill - but steel is made, not mined. Steel, depending on what final characteristics they're trying to develop (strength, hardness, finish , etc.) can be comprised of iron, carbon, manganese, phosphorus, sulfur, nickel, chromium, etc. in varying quantities.
Q:For those metal experts out there, steel or stainless steel.?
S/S. We use clam rakes around here, I think they have a S/S basket with steel teeth to dig into the sand. By the way, I believe S/S is just steel with nickel added, but I could be wrong.
