  RAL Scale Z35 Prepainted Rolled Steel Coil for Construction Roofing

Description of RAL Scale Z35 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.

Q:Is carbon steel strong?
The term carbon steel by itself doesn't mean much. All steel has carbon in it. The definition of steel is iron that has been heated and had carbon dissolved into it and trapped on cooling into its atomic matrix. The amount of carbon in a particular piece of steel does have an effect on its properties. The more carbon it has, the harder it is, but also the more brittle it is. So you can have a high carbon steel blade which is very hard, and holds a great edge, but is likely to break. Or you can have a low carbon steel blade that is very tough and hard to break, but dulls easily. Your real, traditional samurai swords were made to have a core of low carbon steel, jacketed with an outer layer of high carbon steel. Thus they were very strong and hard to break, yet had an extremely hard, sharp edge. If that's what you have you can probably whack away to your hearts content. But you probably have some kind of homogenous steel reproduction type blade. What you can do depends on what steel was used.
Q:Pre Fabricated Steel Buildings?
just google pre fabricated steel buildings
Q:acrylic vs. steel tapers which is better?
Steel is better. Acrylic is porous so isn't as suitable for piercing jewellery as steel. Steel can also slide through easier for some people, acrylic isn't quite as smooth. For tapers it doesn't make a huge deal of difference as they're only passing through your ear briefly, not being worn as jewellery, but if they're close in cost anyway then go for the steel. And the plugs you insert after putting the taper through should always be steel, titanium or glass until your stretch has healed.
Q:Is it harmful to cook on stainless steel?
Stainless steel is one of the safest things to cook on, because it doesn't release metal particles into your food.
Q:What are the end uses of steel coil? galvanized steel coil?
Steel coil is the name given to thinner sheet steel when it is manufactured - it comes out of the machine and is formed into a coil for ease of handling storage and transportation. Thin sheet steel is used for plenty of stuff. It can be slit (cut) into thin strips as well as just cropped and used at one of the standard lengths x widths it leaves the mill. There is a big market for this material. It is used in many construction and engineering applications for things like ducting, boxes, gutters, down pipes, flashings, panels, car bodies etc., anything made of thin steel Galvanising is a flash coating of zinc which improves it's corrosion resitance. Cost wise it is a relatively cheap material. The chemical composition of steel varies, it is mostly iron but has various other elements added or present as impurities that change it's characteristics, depending on the end use. These additional elements can be selected to give better weld ability, hardness, tensile strength, corrosion resistance, flexibility and so on. In many applications excess of these chemicals is undesirable. For example sulphur and carbon are generally better at lower levels. The chemical composition data is contained in a material data sheet and expressed as a percentage of the chemical present and which gives the composition of a particular batch of steel, allowing it to be selected for particular applications and traced for quality assurance purposes. The list you have there shows presence and quantity of other elements in a particular batch of coil. The thickness is 0.23mm, quite thin.
Q:Why are most homes framed of wood rather than steel?
Steel cost more and is very heavy. It would take a piece of equipment to put each piece in place. Holes would have to be made in the steel. Nails will not go into steel. How would the foundation be made?
Q:Will this temperature affect the strength of steel component parts during the galvanizing process?
depends on what your are dipping...i.e what its composition and properties were, was it a spring steel prior?
Q:Whats the differene between steel and stainless steel ?
from wikipedia: In metallurgy, stainless steel, also known as inox steel or inox from French inoxydable, is defined as a steel alloy with a minimum of 10.5% to 11% chromium content by mass. Stainless steel does not corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity, or poor circulation environments. It is also called corrosion-resistant steel or CRES when the alloy type and grade are not detailed, particularly in the aviation industry. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and resistance to corrosion are required. Stainless steel differs from carbon steel by the amount of chromium present. Unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film (the rust) is active and accelerates corrosion by forming more iron oxide, and due to the dissimilar size of the iron and iron oxide molecules (iron oxide is larger) these tend to flake and fall away. Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion and blocks corrosion from spreading into the metal's internal structure, and due to the similar size of the steel and oxide molecules they bond very strongly and remain attached to the surface.
Q:what material could replace iron or steel?
Material selection is a complex area. Iron and steel are very good materials in terms of their strength, stiffness and hardness (especially when compared to their density to give specific strength/stiffness. They are also relatively cheap and the economics of material selection is often the over-riding criteria. Each individual substitution has to be considered on the merits of what the component has to do and the environment in which it operates and often to replace steel with, say, aluminium, might not be appropriate or might require a redesign of the component to accomodate the lower strength and stiffness. Take one of your examples of a dishwasher; To replace the (cheap and thin) steel outer casing with aluminium would require thicker sheet to achieve the same stiffness. To replace the stainless steel inner you would need a corrosion resistant material (which rules out aluminium) which can be easily fabricated to shape. Nickel alloys would be harder to process and very expensive, but you might be able to use a bronze alloy. If you have time look in the library for a book on materials selection by Ashby - one of the best texts on the subject.
Q:Fallout 3 broken steel question?
Broken Steel fixes the original ending of the game so that you can continue past the end and continue exploring. The Broken Steel missions also take place after the original ending of the game. One way you can tell if Broken Steel is working though is if you are finding enemies added with Broken Steel (Super Mutant Overlords, Hellfire Enclave Troops, and so on), and if you can level up past level 20 and get new perks added between 20 and 30. You can even see all of these new perks any time you level up, so next time you level up, scroll down and see if there are new perks below the level 20 perks. If there are, then Broken Steel is working properly.
