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:Is Steel a Metal or Non - Metal ?

Q:Wolf ammo/steel case ammo question?
if you were going to shoot thousands upon thousands of steel cases in your rifle, it would cause more wear than brass cases do. but for the casual shooter, it won't be a significant factor. Corrosive ammo is another story (but not all steel cased ammo is corrosive, and any made after 1975 is not corrosive). shooting corrosive ammo in a bolt gun is simple to care for. When finished shooting, simply clean out the barrel, chamber and bolt face etc with hot soapy water, or military bore cleaner. This nuetralizes the corrosive chemicals. then dry it well, and then do your normal clean and lube with break free CLP or whatever other lube you prefer. But for a semi auto, gas operated firearm, the cleaning process takes hours, with having to tear it down and clean every part including gas tube etc. As for the ectractor, same answer as above, since an extractor slides in front of the rim as the cartridge is fed, it really does not add much more wear if it is steel. The firing pin does not contact the steel case, only the primer, so no additional wear there. The biggest problem with wolf ammo is encountered when you fire a lot of rounds quickly, building up a lot of heat, which can cause the lacquer sealent on the case to turn gummy and this in turn will cause problems for the firearm. Answer? first, use wolf ammo for casual shooting and clean the firearm extensively afterwords. Save your better ammo for real life situations. I understand that some of the newer wolf ammo does not use the same lacquer sealant. I believe it is called silver bear, but don't quote me becasue I can't swear that that is it. shoot safe
Q:i wana get my tongue peirced, the only metal im not allergic to right now is surgical steel?
DO NOT USE SURGICAL STEEL. Use IMPLANT GRADE stainless steel, or, even better, IMPLANT GRADE titanium. surgical steel is a marketing term, pioneered by a cutlery company to make their cutlery seem cleaner. So basically, surgical steel can be anything from the forks and knives in your house, to the rusty tools in the shed, whilst implant grade stainless steel is specifically made for medical uses in the body (pins in your foot or a pacemaker in your heart.)
Q:Who Is Dr. Steel?
Dr. Steel is an extremely complex phenomenon, a bit of a metaphorical nesting doll. On the surface, Dr. Steel can appear to some as simply a method actor musician with an over-the-top gimmick. Just underneath that facade lies an enigma; he makes some people wonder if he's really serious, just trying to entertain, or completely barking mad. But underneath the second facade, Dr. Steel is really acclaimed comic-book writer and chaos magickian, Grant Morrison. Make no mistake, he really thinks he is Dr. Steel. He has taken method acting and ceremonial magick to the highest levels, and fully intends to take over (or make over) the world. What's more, in the three short years since handing over his comic-book authorship to a ghost writer, he has amassed tens of thousands of followers worldwide. I've done several polls among Dr. Steel fans, and the results show that for every one person who has officially signed up, there are ten more loyal followers who have not.
Q:Steel Arch Buildings.....!!?
Q:how can one go about melting and casting steel?
Sand casting useing silica sand was the classical method. Wood models called patterns made the cavity into which the metal was poured. Furnaces capable of melting iron and steel are not found everywhere. They are industrial machinery, not to be improvised. Some-one had better be very careful if he does get access to molten steel. There are some aspects of the process that are not intuitively obvious that can 'bite you' badly. Get at least some briefing from an experienced foundryman.
Q:Can you use steel strings on a classical guitar?
NO ! NO! NO! Do not put steel strings on a classical guitar!! The increased tension can actually damage the guitar by causing the top to warp and can eventually pull the bridge right off of the guitar! I have seen it happen more than once! Ignore the other post, they are wrong! Classical guitars are designed to use nylon strings only!
Q:Stainless Steel Pots and Pans?
First, they must be absolutely shiny, clean. Use a scouring pad in circular motions to make them as smooth as possible, then use Non-stick spray, but read the label, some oil sprays contain water and they will stick every time. Spray with canola or pour canola in the pan and warm it up before putting in the food. For flavor you can mix the canola with some olive oil or butter, but don't overheat or they will smoke and burn. For frying pancakes or eggs, the best choice is a teflon coated pan, use an oil spray and medium heat only.
