cold rolled hot dip galvanized steel coil/

Galvanized steel coils are widely used in the construction industry, as raw material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommended for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 100 – 180 grams per square metre.

Hot-dip galvanized steel coils are produced by immersing steel in a zinc bath. An appropriate galvanizing process requires a pretreatment process during which the steel passes through different baths which prepare the surface for zinc coating. In this stage, chemicals are used to clean the surface of the steel. After the chemical treatment, the steel coils pass through a bath of melted zinc at temperatures around 460 ° C. The resulting uniform coating is finished through a process of skin-passing to provide smooth and shiny appearance of the finished product. To store for a longer period, the hot-dip galvanized coils can be delivered with a final oil coating, according to the customers demand.

PROFILAND STEEL produces hot-dip galvanized steel coils with very good workability at further cold forming and bending processes.

Technical specification for the hot-dip galvanized produced by PROFILAND STEEL::

Steel grade: DX51D+ZZinc coverage: 30-180 g/sqm on both sides (depending by the requested specification);Thickness: between 0,2 mm and 1,00 mm;Width: 600mm,914mm,1000mm, 1220mm and 1250 mm;Coil weight: 4-6 mt;Coil ID: 508 mm;Coil OD: 900-1500 mm ;

Depending on their usage, the hot-dip galvanized coil can be delivered slightly oiled.

Q:Steel Wool + 9V Battery Question...?
The reason the steel wool catches fire is because the strands of steel are so fine and they have a high resistance. The thin strands get to red-hot very quickly, compared to larger gauge copper wire which has lower resistance and can dissipate the heat over its larger mass. When you connect the battery to the wire first, then touch the steel wool, you are making solid contact with the steel wool and your hand makes sure that the wire stays in contact. The current continues to flow and the wool heats up. When you connect the wire to the steel wool first, as soon as you connect the battery the current melts that tiny bit of steel wool touching the wire and electrical contact is lost. The current stops flowing. No fire. If you want to connect the wire first and not have to hold it, you have to make sure that the current keeps flowing, perhaps by using a braided copper wire and spreading out the individual strands to make multiple contacts. Either that, or remove the insulation from a longer section of the wire and make sure that the entire un-insulated part of the wire is in contact with the steel wool. Maybe even weigh it down. Remember that any strands of steel wool touching that wire will melt as soon as the current starts, so you have to make sure that the wire will maintain contact somehow, the same way that your hand pushes the wire against it.
Q:knowledge of steel composition?
You have opened a can of worms. Specific types of steel vary not only by composition but by the way they were made, their physical properties and their morphology (microscopic structure). The composition you have given would fit for High Carbon Steel and Medium Carbon Steel. Go to the reference I've given, it allows you to put in 3 of the components of your alloy and then it gives you a list of possibilities. You can open each candidate individually and see the full composition. Hours of fun. :)
Q:what is the origin of stainless steel?
In metallurgy, stainless steel, also known as inox steel or inox from French inoxydable, is a steel alloy with a minimum of 10.5% chromium content by mass.
Q:Metro Roof Products? steel roof?
Steel roofing Pro...life of product is much longer then Asphalt shingles....Looks great...multi colors.......Just love the stuff... Cons....More costly then singles at first but since it last longer it is really a better buy.......
Q:What steel is the most magnetic?
Silicon steel is the most magnetic material for making into transformer cores and motor cores. It contains 1.25 to 2.5% Silicon. Silicon steel is usually rolled to 2mm plates as lamination material. Iron may be magnewtic but it has low resistivity. With high silicon alloyed to iron resistivity is increased and core and hysteres are losses reduced. Important silicon steels are designated as AISI M15, M19,M22 and M36. In ASTM, these steels are designated 36F15, 36F18 and many more.
Q:Anyone else love the TNA Steel Cage? +BQ?
TNA steel cage is alot more better i agree with you its safe and can see through it just fine on camera.. BQ: i think newer fence type because it does slow down a match and its brutal.. Old blue cage is just a bit too wide that someone can easily jump two or three squares up and finsihed, nah its too quickly finishing a match into that cage.
Q:Best steel to make a custom knife with?
If it does not could desire to hold an part o.k. then 440 stainless could be your appropriate guess. I want severe carbon steel. yet they require alot of cleansing and oiling or they're going to rust.
Q:A question about steel?
I think it might be a bit brittle and could break from metal fatigue.
Q:Help with Steel and Iron please?
Iron is an element. Steel is an alloy made of iron. Mild Steel, or Carbon Steel is made from at least 98% iron in a preocess that involves controlled application of heat. Other Steel Alloys contain significant ammounts of other elements. In the case of Stainless steel, these elements are Nickel and Chromium. In plain steel, the carbon content varies from 0.15% to about 1.4%. The higher the carbon content, the harder the steel is. Over 1.4% carbon, the steel becomes so hard that is also becomes brittle. Carbon content is also used to control the hardness of stainles steel. Because Stainless steel is corrosion resistant, it is often used for making food preparation equipment. Aluminum is NOT a common element in steel. Aluminum reacts to silicon content similarly to the way Iron reacts to carbon content. High strength Aluminum alloys often contain Magnesium.
Q:For those metal experts out there, steel or stainless steel.?
Whilst doing a welding course a few years ago the teacher said stainless steel was not its proper name,it is called Heat and Corossion resistant steel,it come in different grades related to its corossion resistance,priced accordingly.Must be welded properly without introduction of carbon to the weld (carbon pickup) or the weld might not be there next time you look dependant on environment.Generally harder to form than mild steel (low carbon steel) so it will tend to be stronger than lcs for the same cross section.steve
