 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:quinching steel... hardening?
boy what a though question ! let me explain. when you rapidly cool a steel from high temperatures(depending on steel type) with water or oil or other means , it is called quenching. it depends on the steel type to say if it is better to quench it with oil or water but basically in water you will have a harder steel rather than oil. for some steels if you do this you will ruin it's properties ! you can't totally tell what kind of steel do you have until you get it analyzed with Quantometer analyzer with a pocket knife it is more like an estimation and it can't be trust able generally if you can scratch the steel with your knife it means it is not a hard steel and it might not be expensive. I hope that helps but for more information i need to know more !
Q:What are surgical steel earrings ?
Surgical steel is a grade of steel often used in medical appliances like tweezers, forceps, etc. It's generally non-reactive and considered very safe. It doesn't contain any special properties against infection--you still have to observe basic hygiene and clean your piercings properly--but most people can wear surgical steel earrings without a problem. However, if you have a contact allergy to base metals like nickel, surgical steel may cause redness or irritation because of the metals used in it. If cheap rings or necklaces make your skin break out in a rash you should NOT wear surgical steel.
Q:difference between titanium and stainless steel?
Stainless steel is more corrosion resistant than steel and titanium is more corrosion resitant and lighter. However, titanium is more prone to picking up (scratches caused by normal tools creating scratches and leading to stress fractures). The Lockheed Blackbird had to have tools treated lithium grease (i could be wrong) to prevent this. I'd stick with stainless steel as i think any titanium exhaust you can buy will be a titanium composite due to its cost
Q:.308 steel cased ammo in my remington 7400?
Should you?...... Its a free country - You can do what you want....... Why shouldn't you?...... If I got it right - That Herters ammo is foreign made steel case ammo..... Most of that stuff has a reputation for being dirty and likes to foul semi-auto rifles up..... I suppose if you use a little of that stuff now and then it would be ok........ Usually that steel cased stuff is used by folks that own military style semi-0auto guns and bolt action rifles...... Those types of guns for the most part are well suited to use that cheap steel case...... A Remington 7400?..... This is just my opinion - but that's a hunting rifle and isn't up to the rigors of blasting a few hundred rounds of ammo off in an afternoon....... Get a different gun for that...... Occasional use?... Yeah its alright...... If this is for hunting use a better grade of brass cased ammo.......
Q:truth of steel Sword making?
I am unsure of what the Truth of Steel is, but here is the Riddle of Steel (from Conan) Thulsa Doom: Yes! You know what it is, don't you boy? Shall I tell you? It's the least I can do. Steel isn't strong, boy, flesh is stronger! Look around you. There, on the rocks; a beautiful girl. Come to me, my child... Thulsa Doom: [coaxes the girl to jump to her death] Thulsa Doom: That is strength, boy! That is power! What is steel compared to the hand that wields it? Look at the strength in your body, the desire in your heart, I gave you this! Such a waste. Contemplate this on the tree of woe. Crucify him!
Q:steel guitar, can i use bronze strings?
I don't see why not. Put them on and try it out.
Q:Stainless steel or Carbon steel knives?
If your talking about a folding pocket knife, I think that it's basically six one way and a half dozen the other. I actually do prefer stainless for my pocket knives. I don't want to oil a knife to the degree I feel carbon requires, only to then stick it my pocket to attract dirt to the knife and oil to my pants. I'm the exact opposite on sheath knives though. I like 1095 carbon steel, plain edge sheath knives. I'll thrash on them HARD, and I rarely have major edge problems. Of course, I require them to be coated with some kind of powder coat or the like, because they can rust, but I do try and keep them clean and dry when in the sheath, so they won't pit the uncoated edge. My reasons for this sheath knife preference is multi-fold. First, these knives are simply affordable. I don't spend $80 dollars on a outdoors sheath knife. I use the tool too hard to want to spend more. I don't like the more traditional stainless steels such as AUS-8, 420HC, and 440C (not to mention the HORRENDOUS 440A) because I feel that the all else being equal, a stainless blade will bend before a carbon blade will break. I also think that carbon holds an edge at least as well, if not better, than traditional stainless, and it's much easier to hone. I don't know much about these new laminates, other than the very hard, but not so tough. They seem to be POSSIBLY too brittle for my use. That, combined with the fact that they cost a FORTUNE, means that I just won't be considering them.
Q:High Speed Steel Information!?
wikipedia: High speed steel (often abbreviated HSS, sometimes HS) is a material usually used in the manufacture of machine tool bits and other cutters. It is often used in power saw blades and drill bits. It is superior to the older high carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high speed steel. At room temperature, in their generally recommended heat treatment, HSS grades generally display high hardness (above HRC60) and a high abrasion resistance (generally linked to tungsten content often used in HSS) compared to common carbon and tool steels. see reference for more info .
Q:Buoyancy question. Why does a steel nail sinks but a steel ship floats.?
A steel nail is much denser than the water. That means that it weighs more than an equivalent volume of water. Therefore, the buoyancy is never going to be enough to hold it up. Whether it is a big steel nail or a small one, it will always be too dense for the water to support it. Because of its shape, a steel ship is not as dense as water. It is not made out of a solid block of steel. Instead, the hull is built of thin plates of steel enclosing an open space. A steel ship is sort of like an empty cup. Although its sides are hard and dense, it holds a lot of air in the middle. Since air weighs almost nothing, it lowers the overall density of the ship to a point where its buoyancy exceeds its weight, and the ship floats. Think of it as you trying to sink a balloon.
Q:how to make a unique piece of steel?
If you're looking to make steel stronger, I can suggest 2 things: 1. If you're actually smithing the steel yourself, and forging it from hot liquid metal, then if you can get ahold of some Carbon (i have no idea where you can get some), you can add it to the molten steel to make it stronger. Sword Smiths did it all the time back in the Dark Ages. (you'll have to look up the exact Science and Process of how to do it) 2. There's a treatment for steel called Tempering. If you Temper the steel, it makes it stronger. You do this by 1st Forging what you're making. In this case, I'll use a sword. Take the Sword and re-heat it (i dont know the exact temperature) until it glows-hot. You can use a blast furnace, a campfire, or any other extreme-source of heat. Some companies use molten Salt - yes, the Condement, and dip the sword in it until it's glowing-hot. Now you have to super-cool it. This is simple, all you need is Ice water. Submerge the Sword in it, until it's cool to the touch. Now toss the Sword back into your source of extreme Heat. Get it glowing hot, and then take the sowrd out. Set it aside, and let it cool naturally. Once it's cooled, it's TEMPERED, and alot stronger. NOTE: If you stop at the ICE-WATER stage, you'll only succeed in making your Sword BRITTLE. You MUST Continue the Process once Started. - Hope this helps.
