 prepainted rolled Steel Coil for Construction Roofing Constrution

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:Steel Making Process?
From what I understand of it, US steel is better as the steel is more recycled than Canadian, so a lot of that oxygen / CO2 has already taken place compared to working from ore. The second reason US steel is environmentally ahead of Canadian is that US tends to use Electric Arc, while Canadian uses Basic Oxygen, Basic Oxygen uses more energy than electric arc, and I think it also uses more oxygen, but I would suspect that oxygen that it uses is 'waste oxygen' and not converted into Co2 because the Co2 process is limited by the carbon, and steel only has so much carbon.
Q:whats the average price of wide flange steel W10x30?
The price of steel is increasing daily, so an exact answer is rough. A W10x30 is a fairly common shape and shouldn't be too hard to find. For a very rough ballpark number, say $700/ton (installed price), the piece you require should be in the range of about $250.00 or less as I assume you'll be doing the installing. Please don't take this as the gospel, however. Price varies on location, stock, and availability. Open the phone book and contact your local steel supplier. Because the piece you require is fairly short, you might get lucky and find someone who has a waste piece that length that they will give you a good deal on. --------------------------------------... I just checked the AISC web site to verify the number I quoted above and they posted an article stating that the average mill price had just increased to over $1000/ton in May. The best advice I can provide at this point is to buy the W10 now and don't wait any longer.
Q:Damascus steel sword question?
There okorder.com, the true Damascus is a region of spain, which is similar to getting swords made in Pakistan
Q:crossbow hunting with 8mm steel balls?
An 8mm steel ball fired from a 150# crossbow is probably going to damage your crossbow. Crossbows shoot arrows (or bolts), NOT ball bearings and, furthermore, a 150# crossbow needs an arrow (or bolt) of about 450 grains in order to be efficient and operate without damaging itself. A 450 grain arrow will kill small game very well and out to a range of about 30 yards. Don't wind up like the guy below... EDIT: Racing Pace Stick - I stand corrected. There are, indeed, tacticool crossbows that shoot ball bearings and they all seem to come straight from Shandong Province, China. Note that these are not implements suited to hunting. Also note that if you shoot an 8mm steel ball out of a 150# draw compound crossbow that IS suitable for hunting, you are probably going to break it.
Q:Who invented the steel windmill?
The Steel Eclipse Type WG was the first of several self-oiling steel windmills marketed by Fairbanks, Morse, and Company after they became the distributor of all the Eclipse mills about the start of the 20th Century. It has the more important distinction of having been the only widely distributed worm-gear mill in the history of American windmill manufacture. Produced from about 1926 to the mid-1930's, the Steel Eclipse remains in the field today in considerable number in most parts of the country. Hope this helps!
Q:Is stainless steel stainless all the way through?
Yes, stainless steel is stainless all the way through. All metals are uniform in composition throughout the piece. However, many metal items are plated to give a different finish from the base metal or to provide protection. An example is galvanized ductwork. The duct is made of steel, but a coating of zinc is plated onto it for corrosion resistance. Likewise, some items are made of steel or brass, but are chrome plated to present a bright, shiny appearance.

Q:Where are the coils and the steel plates used? Where did the steel plate come from?
The use of steel coils, refrigerators, washing machines, household appliances, and other industries, parcels are winding.Steel plates can also be found everywhere: airplanes, guns, trains, ships, space shuttles, spaceships, automobiles, etc..Steel plate through mining - sintering - iron smelting - smelting - forming.
Q:Does steel give off harmful gas when heated?
Steel often has impurities that can generate fumes, which cause a fever identical to smoke inhalation. You always need to be concerned about what you are breathing around hot metal.
