Product Description:

Hot Dip Galvanized Steel Coil in Coil

Description

Galvanized Steel Coil gets coated in layers of zinc because rust won't attack this protective metal. The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel. These multiple layers are responsible for the amazing property of the metal to withstand corrosion-inducing circumstances. Zinc also protects the steel by acting as a "sacrificial layer." If rust does take hold on the surface of Galvanized Steel Coil, the zinc will get corroded first. This allows the zinc that is spread over the breach or scratch to prevent rust from reaching the steel. For countless outdoor, marine, or industrial applications, Galvanized Steel Coil is an essential fabrication component.

FAQ:

1.How about the package for the Hot Dip Galvanized Steel in Coil?

Usually Standard export seaworthy package: waterproof paper+steel trip packed+wooden case seaworthy package

2. Can I know the production period of the goods?

Usually it need 20 days for 25tons in one container. We can produce 300 tons per day but we need to arrange the production in advance.

3. How about the label, could you make the label according to pour requirements?

Usually we use the MILL label, but if you need special form we can make.

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:Does steel contain nickel?
Yes. Different alloys contain differing amounts.
Q:is CS material is comes under Mild steel? any difference?
*Carbon steel, also called plain carbon steel or Mild Steel, is steel where the main alloying constituent is carbon. The AISI defines carbon steel as: Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0.40 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60. If it crosses limit as said, it will come under alloy steel. ASTM A 106 gr B is a carbon steel pipe and seamless Pipe for High Temperature Service. So, it will be a mild steel comes under carbon steel category.
Q:What is the difference between steel toe boots and composite toe?
steel toe boots are just that a piece of steel fitted over the toes, composite toe boots use other materials that are just as hard BUT they do not have the connectivity levels as steel. if you are working in a cold climate steel toes will freeze them toes right off, also electrical environments. my advice get a good pair of composite ones, and you get what you pay for, its worth the investment. more than you could ever imagine. proper foot support. helps legs cramps, back pain etc...
Q:i know stainless steel don't rust, does that go the same for just regular steel..?
There are dozens of types of steels, some stainless and some not. They differ a lot in their chemical composition and in how they're made (especially heat treating methods). They all vary in their strength, working properties and corrosion resistance. Regular steel (technically carbon steel--mostly iron, with a little bit of carbon) rusts quite badly if unprotected and in the right environmental conditions i.e. humidity/moisture. The iron in regular steel reacts with oxygen to form iron oxide--the orange/red stuff we call rust. Iron oxide is a loose and porous material which provides no protection to the underlying steel, which is why rusted regular steel will continue to rust. Stainless steel, in addition to containing iron and carbon, contains chromium as a component--and it's the chromium that is important for corrosion protection. To be fair, even stainless steel rusts but what happens is that it's the chromium that reacts with oxygen to create a microscopically-thin layer of chromium oxide. This layer is very tough and actually protects the uncorroded steel, preventing further corrosion. Broadly speaking, the higher the chromium content, the more corrosion resistant the stainless steel.
Q:i have guestion a bout steel?
Stainless Steels are alloys that are made up of iron and generally contain around 11.5% chromium. For obtaining special properties, nickel, carbon, chromium, and other elements can be added to it. There are four types of Steel : Carbon Steel Alloy Steel Stainless Steel Tool Steel From kitchen utensils to cutlery, sinks to machine drums, as well as microwave oven liners mainly, use Stainless Steel. One can find different types of products such as Stainless Steel Tube Fittings, Pipe Fittings, Flanges, pipes, Tubes, Fasteners, Sheets, Rods, Bars and so forth are used in different industries. List of typical applications of these Stainless Steel products include: Oil and gas equipments Offshore technology Seawater desalination plants Chemical industry Bridges Storage tanks Medical Industry Civil Engineering Pressure vessels, reactor tanks, and heat exchangers Rotors, impellers and shafts Power plants Petrochemical Shipbuilding industry
Q:Is diamond lighter than steel?
Diamond has half the density of steel but would make a terrible sword because it is not very tough. Toughness is a material's ability to resist breakage from forceful impact: Diamond has a toughness of 2.0 MPa·m1/2 and has a critical stress intensity factor of 3.4 MN·m−3/2. That makes it tough for a gem but are poor compared with steels. Plus diamond has a cleavage plane.
Q:im getting a sword tommoro and i need to figure out the pros and con of stainless steel and carbon steel sword?
For display stainless is ok, no maintenance is required, for actual use carbon steel it the way to go, these blades will rust and need to be taken care of.
Q:steel refining process?
As Mr. Perfessor says, refining raw steel involves a lot of purifications of the raw steel; and to expand a bit, these refining processes also add corrosion-resistances to certain graded steels, and durability factors, when heat-tempering processes are used. All of these refining processes, and coating processes help steel products last when exposed to moistures, salts, and other corrosive conditions that steel can be exposed to, whether the steel is in open-air/water/space, embedded in concretes and other masonry products, or part of a protective barrier system in power plants, engines, etc. Hope this also helps; the eggster.
Q:What's the length of a coil of cold rolled steel? Is there a standard?
Generally there is no standard length, to customer demand to roll weight, because customers with steel coil production capacity is different, lifting ability of a volume can do longer, on the contrary, do small points.
