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:Which is stronger for cars, carbon fiber or steel?
Depends on the design/construction.
Q:Does anyone know anything about Kodiak Steel Homes?
Steel framing replaces all the wood making the house stronger and resistant to termites. Costs about $2,000 more per house and there is a lack of trained framers in most cities. Never heard of Kodiak brand. Do you know a city where they are located?
Q:Steel & Iron Industry?
Steel is made from injecting air into molten iron
Q:types of steel.......?
steel is the best material for a real sword
Q:Steel Building Kits...!!?
I put up a 30'x40' Mueller Steel Building from a bolt together kit 6 yrs ago. Fully insulated, 2 10'x10' roll up doors, 1 walk thru door, 3 windows, 2' overhang all around, and gutters. The building price minus the slab was about $9500. The only special equipment was a neighbor's large Farmall with a hay spike on the FEL that we used to lift the trusses in place. Then it was mainly cordless drills to put in LOTS of self tapping screws, circular saw with metal cutting blade, tall ladders, etc. Had help putting up the trusses and putting up the roof panels. Everything else I did by myself. Took about 6 wks, but that was only working weekends and maybe 3 evenings a week since that land is 30 miles from my house. Would have gone a lot faster with at least one helper.
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:Steel shafted woods vs Graphite woods?
I'd be very surprised if there are any tour players still using steel shafts on their woods (I did actually see Tiger with a steel shaft on a driver during a clinic in 2002). Top end graphite shafts have gotten so much better there's just no reason for pros not to use them anymore. That being said, I use a 45 True Temper stiff steel shaft in my driver (Cobra X-speed, 9.5*). Graphite is longer than steel, but the distance I've lost is minimal (maybe 10 yards and I still put it out there 250+ consistently). The extra weight has actually helped me stay in control which has improved my overall driving considerably, and the very low torque in a steel shaft has paid off huge in accuracy. You're paying minimum $60 (or more) for a graphite shaft with a similar torque rating to any steel shaft. I hit easily twice as many fairways since the switch. I've even switched out my other fairway woods too, the feel and control are so much nicer. I've considered going with a 46 on the driver to try to regain some of the distance, and at $7 per shaft I can actually just go do that whenever I want. Don't get me wrong, if I were playing for money or flirting with par I'd invest in good quality graphite stuff no question, but it doesn't make sense to me right now. I'd recommend to anyone looking for more consistency out of their woods to take $20 to your golf shop and try it out. It's a lot cheaper than the alternatives.
Q:Alloyed to make stainless steel?
E. Stainless steel is mainly comprised of Cr and Ni. Steel is an alloy composed mainly of iron. On a side note, Carbon is not really in stainless steel and it is only less than .1%
Q:When was steel first used in buildings?
steel was first used in the 1800s in buildings.
Q:Is T-304 Stainless Steel dependable?
Stainless steel is available in 2 grades - 304 and 316. The 304 has traces of ferrous to make it adaptable for the intended purpose. The 316 is non-ferrous and a bit more expensive. Whereas the 316 will not inhibit rust, the 304 will show some flecks (which can be cleaned away) over a period of time. It, however, is as good as the other.
