Structure of Al-Zinc coated steel coil

  Al-Zinc coated Steel Rolled Coil for Roofing

Description of Aluminum Zinc Rolled Coil
The detailed information for the Al-Zinc coated steel coil is as following and it is mainly using for roofing producing, making ceiling grid and all kinds of roll forming structure.
Thickness: 0.20mm to 1.20mm
Width: 914mm, 1000mm, 1200mm, 1219mm and 1250mm, or slit narrow strip according to customer request, can be slit from 20mm to 610mm.
Coil ID: 508mm
Coil weight: 3 tons to 6 tons
Thickness tolerance: +/- 0.02mm or according to customer request.

 

 Main Feature of Al-Zinc coated steel coil

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:can you put nylon strings on a steel string acoustic guitar?
Nylon Strings For Acoustic Guitar
Q:Questions about Steel. Please Help?
It is usually a grey color, more silver when freshly scratched. Every one of the other questions can range based on the quality of the steel and other variables such as thickness. That's more than likely the reason you couldn't find any info on it. Its hardness is based on quality, for example regular steel is softer than Mild steel. It can be a thin sheet or a thick plate (which could then be changed to a tube Circle or square) etc
Q:A simple question: Corten steel?
Weathering steel, best-known under the trademark COR-TEN steel and sometimes written without the hyphen as Corten steel, is a group of steel alloys which were developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. Overheating ? It's not possible for a metal to get hotter than it's environment unless there is a source of radiation. The sun shining on a metal will heat up a bit, as will any material, but the amount is small and depends on the surface reflectivity. Define what you mean by overheating. .
Q:on pokemon diamond what pokemon are week to steel types?
I believe Ground-type, Ice-type, Rock-type, Dark-type, Normal-type, Psychic-type, and Ghost-type Pokemon are weak to a Lucario. Steel is super effective against Rock and Ice-type Pokemon. Fighting is super effective against Rock, Ice, Normal, and Dark-type Pokemon. The reason why I added Psychic-type and Ghost-type Pokemon to the list of Pokemon that are weak to a Lucario is because Lucaro has the ability to learn Dark Pulse at high levels, so if he knows this move, then he should be able to deal super effective blows to Ghost and Psychic-type Pokemon. Of course, these are only if the Pokemon that you are facing is a single-type Pokemon. The Pokemon that you face will determine if a move is weak against it or not. Study up on the Pokemon you are facing and what types they are so that you can determine if your Lucario will be super effective against it or not. Have your Lucario stay away from Fighting-type and Fire-type Pokemon as they are both super effective against Steel-type Pokemon. Hope this helps :)
Q:Can carbon steel be solution annealed?
No. Carbon steel has two different crystal structures, FCC and BCC , depending on the temperature. when you heat steel up and then quench it, it locks the crystal structure into the BCC form. this makes it hard. whereas precipitation hardened austentic stainlesses remain BCC regardless of the temp, so the hardness change is not a function of thermally induced strain. you can anneal carbon steel but the thermal profile is closer to the precipitation profile of PH stainlesses than it is to the Solution annealing profile.
Q:what type of steel is used to make rail tracks?
I don't know what the technical name is, but steel used in rail is higher in carbon content. There is a trade-off as the higher carbon content tends to make them more brittle, and those rails with the highest carbon content are used exclusively for tight curvature in heavy grade. It's amazing to watch the welders with this stuff. Torches take too long, so diamond saws are utilized for cutting. The stuff is more problematic in severe cold, too. Railroading in the mountains as I've always done, nighttime and its severe chill causes pull - aparts, due to the contraction of CWR (Continuous Welded Rail) as a result of the cold, at least two or three times a week. In an extended deep freeze, the problems are nightly. What is interesting to note is that the pull aparts tend to happen with equal frequency regardless of whether a part of tangent track or curve. Still, I'd rather have it under me. I know it caused some major problems on the SP in the '80s, but it was cheaper, imported steel that was the significant part of the problem, not so much the high carbon content. Once again, you can't beat US steel.
Q:Steel Tensile Strength?
I don't follow your calculations. It seems to me that the piece you show could be made from .01 steel and still be less than a pound. Also, it is hard to get steel thinner than .015 because anything thinner is not very useful. If you made it out of .015 steel and used a high strength steel, it might be useful. You wouldn't be bashing any skulls, but with some spikes on the end, it could do some damage, and protect against knives or other hand weapons. You also won't get any bullet resistance out of anything that thin. If you want to bash skulls and deflect bullets, you have to get up to at least .10 and several pounds. Any weight on your hands slows down the speed of your punch, but this is compensated for by the increased energy of impact carried by the extra mass. Also, having something hard to protect your hands allows for harder hits and more damage to the opponent. An interesting idea, but it would take some testing to figure out the optimum configuration. One problem I see is that it completely encloses the hand, making it impossible to use the hand for anything else. So you would have to put it on and take it off a lot, and there would be cases where you wouldn't be able to put it on when you needed it. For that reason, I would not wear two at one time. I would make it heavier and wear it on one hand for bashing skulls and deflecting weapons, and keep the other hand free for other things.
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:Would aftermarket steel wheels weigh more than stock jeep wheels?
steel is steel is steel- they will always be heavy you would have to weigh them to find out--NOW if you are going to alloy wheels they are typically aluminum and yes they are lighter -this is good because it lightens your un-sprung weight and is less harmful to your suspension-good for your auto
