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:Stainless steel ring?
My hubby and I have some and they have stood up VERY well. He used to work with drywall, and the ring was SO easy to clean. I work with dogs and have not had a problem with my ring, either. They are heavy duty and stand up to time. LOVE them!
Q:A question about steel.....?
As first answer says, if you look at the number of commercial steel alloys available and consider that any given alloy can be heat treated to a wide range of physical properties, there are thousands and thousands of potential combinations. Technically, steel is an alloy of Fe and C but there are Fe-C alloys that are called cast irons, not steel, and... there are lots of alloy steels which have significant amounts of other elements added like Cr, Ni, Nb, V, Mo, etc. Fe alloys that have a lot of Cr and or Ni added are called stainless steels and there are dozens of them and many of them can be heat treated to produce a wide range of properties. As far as the strongest or the weakest, you have to get really specific about exactly what you mean because some steels are designed for room temperature properties, some are designed for elevated temperature properties, some for static loads, some for impact loads, some for wear resistance, etc, etc.. Steels make up the largest family of metal alloys (by weight and by volume) that humans use. There are a number of reasons for this but the big reasons include: 1) there is a LOT of iron on earth 2) it is relatively cheap to produce 3) you can easily change the physical properties over a every wide range. As an example... you can take a piece of steel that is so brittle it will shatter if you drop it on the floor and heat treat it so you can bend it like a pretzel without cracking and then heat treat it again to make it very strong and tough (resistant to fracture).
Q:Is Diamond stronger than Steel?
diamond are hard but it is not stronger than steel because diamond is a kind of element but the steel is not .steel are influenced by the people

Q:Here is my dilemma, should I shoot steel case ammo in my ar15?
steel case does not cause additional wear to the gun's chamber when compared to brass case. many tests has been done and precise measurements taken, this myth has been proven false. lacquer coating can cause issues because it can melt and cool, and cause jams. this is easily remedied with a chamber brush and some solvent.. However, steel jacket causes problems. Steel is harder than copper, it does not deform as easily so it causes more wear to the barrel as compared to copper or brass. The rate is around 10-25%, inreasing if you hoot rapidly instead of slowly. more shooting = hotter barrel = faster wear. It's the same with copper/brass jackets, but steel jacketed always wears more than softer metals. TulAmmo (or tula) is particular is so cheaply made they don't have enough copper/brass wash on the bullet to survive firing, after a few inches of travel it's steel on steel contact in the bore and it can ruin a gun barrel very quickly. But... there is one exception. if your gun comes with a chrome-lined bore that is standard for most AR's , shoot all the cheap junk you can buy. chrome-lined steel is 2X as hard as plain steel. crappy tula .223 will not cause more harm to a chrome-lined bore more than brass or copper jacketed bullets.
Q:Use of Steel in Jet Engines??
Jet gasoline definitely does get warm sufficient to soften the engines (the cores of that are created from titanium alloy, not steel). in actuality, jet engines could be in particular designed as a fashion to not soften below popular working situations. As for the engines vaporizing it incredibly is extremely not likely. They probable have been pulverized via the impact forces and the debris then melted interior the hearth.
Q:Is it possible to stain steel red?

Q:Engineering Materials - tool steel question?
It all depends what the application actually is. For hammers I would select a hammer grade B1 steel. For impact loading where an edge is needed I would be going for O1 or similar (oil quenching steels tend to be a little tougher than air hardening). For mining tools a very high manganese steel (Hadfields steel) - this is not a true tool steel. The best place to start is by looking at the ranking of the properties which you want - hardness v toughness v strength - and then use this to put the steels in rank order. Price and availablity then sort the problem out for you (in the real world).
Q:were the twin towers made from reinforced steel?
There is no way you could make a 110 floor building out of concrete.
Q:Should I buy a guitar with nylon or steel?
Make your choice based on the type of music you intend to play. Nylon strings are used primarily for classical, flamenco and folk music. Steel strings are used for pop, rock, blues, country, folk, bluegrass.... Both types of guitar are tuned the same, so you *can* play any style of music on either guitar. The big difference is in the tone. Nylon strings are rich and full...if perhaps a little mellow. Steel strings are twangy and have a bite to the sound. There are differences in the construction and feel of the guitars, but that's not critical to your decision. Match the guitar to the music you intend to play. At 14 yrs old, you are certainly big enough for a full sized guitar....and I'll bet you're still growing, right? Even full sized guitars still vary in the size of the body. Try a few out to see how well they fit your reach.
