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 is the accuracy of steel tape inspection
In addition, the project is through the detection of steel tape, steel tape each batch have the error him different, so do projects each into a batch of steel tape has to go through the inspection department, let this batch of steel tape has reached the same error range. All the measuring tools in this project are unified into these steel tape measures, so that the measurement error is guaranteed
Q:Why does stainless steel get rusty?
You can rub the rust off with anything, from steel wool to Ajax. Although if you've previously used steel wool to clean it, that could be why it rusts. We had that problem manufacturing stainless steel railing and had to put it together on an aluminum table and polish welds with grinding wheels that never touched steel. What rusts are steel particles picked up on the stainless surface. Another possibility is that some stainless is more magnetic and usually also heat-treatable. It has just enough chrome in it to classify as stainless but can get minor surface rust. Not nearly as much as plain steel, though. Use a scouring powder like Zud or Barkeepers Friend and a cloth or sponge to polish if it's a sheetmetal surface rather than a bar grille, because these have oxalic acid and no bleach. They don't leave corrosive traces of chlorine behind. In fact, oxalic acid reduces rust to iron powder. Which is really neat if you need to clean a small rusty item--stir one of these powders into water, drop in the rusty piece and check it from time to time. Rinse off any abrasive powder, dry it well and oil it. When the rust is gone, it leaves a fine matte finish behind.
Q:Bike Frame-Aluminum vs Steel?
Dustin You are close, but not quite right. Steel is a great frame material, It can be heavier than its aluminum counter part, But, steel often provides a much nicer ride. Aluminum tends to be a very stiff and rigid ride that many do not like. I have had frames made of all materials. I can say that I have never met a frame material that I did not like. Check the weight of the frames you are looking at. If there is more than two pound (or so) difference then the aluminum frame would be my choice. Soccerref
Q:steel industry?
Since2003, India has been the largest sponge iron producer in the world. In 2005, out of total global production of 56.05 mt of sponge iron, India produced around 11.1 mt (19.8%). In line with production target of 110 mt of steel (National Steel Policy) by FY20, many steel producers have announced their capacity expansion plans by signing MOUs with various state governments like Chattisgarh, Orissa and Jharkhand. The steel producers are expected to add around 8 mt of capacity by FY 08. CARE estimates that during 2006-09, demand for steel in the domestic market would grow at a CAGR of 8.4%. HR steel because of its widespread applicability is expected to grow at a CAGR of 17.5%. During this period, major demand drivers would be Consumer durables, Automobiles and Construction. Domestically, steel prices of flat products follow the international trend. Globally, steel prices are expected to firm up with continued growth in steel consumption. Further, the winds of consolidation have gathered pace with Arcelor-Mittal merger and latest acquisition of Corus by Tata Steel. The Indian steel industry has announced huge capacity expansions. With commissioning of these capacities demand-capacity ratio is expected to decline in FY 09 due to excess capacity. Will this lead to a drop in prices with commissioning of these capacities? With China and India becoming the focus of major global steel companies, will the consolidation of steel industry in these countries continue? For comprehensive analysis and CARE’s future outlook on the sector, please refer to the exhaustive report on the Indian Steel Industry by CARE Research.
Q:Science help!?! steel wool experiment?
steel wool = iron fibers and rusts easily in air iron + Oxygen BUT the blue soap protects the iron at first. that needs to be cleaned off. damp surfaces speed the rusting but compeletly underwater there is not much O2, ther eis some temperature has an effect. the rusting depends ofn the area of the fibers which does NOT change when you cut th epad in smaller pieces. a good beginners experiment In old times thye thought the rusted material would lose weight becasuse it was not solid iron any more careful experiments showed it gained weight and lead to and understanding of chemistry
Q:How to wear out stainless steel?
Just abuse it. You could hit with a hammer, expose it to flame, throw it at or grind it around on rocks or concrete, rub it with steel wool. (be artful in how you do this, the pattern could end up looking too deliberate if you're not careful.) For an example of naturally aged stainless steel, look at some cooking pots/pans. If you don't have any old ones, maybe your parents or someone you know does. They usually get a little banged up/scuffed/stained after a while. (I think the stainless just means it doesn't rust.)
Q:Is Steel crystalline in its makeup?
Steel is made of billions, trillions of very small crystals. This is true of most metals. In order to see the crystal structure of steel, you usually need to cut a sample of it, grind and polish the cut face smooth, then etch the steel with a mixture of nitric acid and alcohol. Without polishing and etching the crystals aren't visible- it just looks like smooth solid metal. Also, in most cases the crystals are small enough that you need a microscope to see them clearly after etching.
Q:What are the brands that sell 100% stainless steel cookware(interior and exterior)?
My SS pans are Prestige.
Q:how carbon is being alloyed during steel making?
Steel is usually made in a two-step process. As you may know, carbon, in the form of coke, is added to the iron ore during the initial smelting process. This is the first step. The conversion of iron ore into raw iron is accomplished with a blast furnace. Carbon dissolves with the iron during the smelting process. The amount of carbon in the iron is generally not controlled at this point as this would be too difficult, the excess carbon is removed in the next step. The result is pig iron which is crude iron that has a very high carbon content, and a large amount of impurities. Pig iron is almost as brittle as glass, and it is useless in this form. In most modern steelmaking operations, molten pig iron is tapped from the blast furnace three or four times per day- it is not allowed to cool. The liquid pig iron is carried in ladles directly to a Basic Oxygen Furnace which converts the pig iron into steel. The basic oxygen converter uses a stream of pure oxygen to burn off the excess carbon. Impurities are also burned off, particularly phosphorus, silicon, and sulfur (which damage the steel's properties.) These elements all have a much higher affinity for oxygen than iron does, so the iron itself remains unchanged. Once the carbon content and the impurities are reduced to the desired level. The oxygen is shut off, and the iron has now become steel. At this point other alloying elements may be added, such as chromium, manganese, or molybdenum. These elements improve the steel's properties, but also add to it's price. If necessary, more carbon can be added as well if the carbon content has accidentally dropped too low. Finally, molten steel from the basic oxygen furnace is poured off. It can be cast into ingots, billets, or thin slabs.
Q:A question about steel?
Hey Ramzi, I met this chick and was wondering if you could tell me if she would make a good wife. Here's your answer: Big Blue, there are a hundred bits of information I would need, and even then there are mysterious factors that affect the outcome. So basically, I don't have the slightest idea. My answer to your question is exactly the same. Without showing exactly how the Simpson Tie is being used, there is obviously no way to know if it is suitable. Can it be tempered? Sure, but again, I give it a 99% likelihood it will not help in your application. Explain it in detail in 5 to 10 sentences. Give us diagrams and photos. If you can't or won't do that, here's Plan B. Head over to your nearest machine shop, and ask the machinist what he thinks. He will ask the probing questions to understand the needs of the part. It is likely a Simpson Tie won't do it but he is in a good position to suggest a workable approach, and then sell it to you. By the way, if this is a load-supporting member of a motorcycle or some other fast moving vehicle, be prepared to get kicked out of the machine shop. The risk of making an error is high and the outcome extremely dangerous. I would not risk a million dollar lawsuit in order to sell you a $10 part.
