Product Description:

Galvanized Steel Coil/Hot Dipped Galvanized Steel Strips Coil Description:

Galvanized steel coil 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.

Main Features of Galvanized Steel Coil/Hot Dipped Galvanized Steel Strips Coil:

Hotdip 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 customer’s demand.

Q:Causes of zinc removal in hot rolled strip
The base plate is coated with an iron oxide layer, which proves that the substrate in the annealing furnace has not been completely reduced to the spongy pure iron required for galvanizing.
Q:What's the meaning of "double light" in strip cold rolling?
Strip strip coiling: general supply, with high dimensional accuracy, good surface quality, easy processing, material saving and other advantages. With the same steel plate, strip by strip material is divided into ordinary and high quality strip two; according to the processing method of cold rolled strip steel hot strip, two.
Q:Reasons for black side of hot strip galvanizing
Luoyang Taihong hot galvanizing factory to tell you the reason, the emergence of the black side of reason is generally divided into: contains too much iron impurities of galvanized steel strip into the liquid, thus causing blackening; resulting in the high current hot galvanized steel blackening;
Q:What are the differences between strip steel and round steel? Where are they mainly used?
Difference between round bar and other steel bars:(1), is not the same, round shape light round, no pattern without ribs, other steel surface appearance is engraved or ribbed, cohesive force that cause steel and concrete, and the bond strength of steel and concrete in the other.(2) the composition is different. Round steel (grade a steel) belongs to ordinary low carbon steel, and most other steel bars are alloy steel.(3), the strength is not the same, low strength steel, and other steel with high strength, the diameter of the same size as compared with other steel, round steel can bear the pulling force than other reinforced small, but the plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, while the other bars in the break before the deformation is much smaller.
Q:What's the reason for the strip after pickling?
Will it use a strong acid wash, and the temperature is too high to destroy the ductility of steel?.
Q:The relation between hot rolled strip and cold rolled coil, hot rolled strip and cold rolled strip
Cold rolled coil (annealed): hot rolled coil obtained by pickling, cold rolling, batch annealing, flattening, and finishingThat is, the biggest difference between hot rolled coil and cold rolled coil is that the heat treatment process is different. (annealing process)Compared to the specific heat roll, the cold-rolled roll has a bright surface and a high degree of finish, but it produces more internal stress and is often annealed after cold rolling.
Q:How to distinguish cold strip steel and cold rolled silicon steel sheet by simple and practical methods
A little further, to buy a measuring instrument of iron loss, the general cold strip can replace the silicon steel sheet, especially low grade such as 1300 and so on, the loss reached 13, low demand can be used instead of cold rolled strip steel production, little more.
Q:Can cold rolled strip be plated with white zinc?
Slight floating rust will not affect, serious rust will affect the quality of the electroplating.
Q:Why is strip heat cheap?
Mainly the production process is not the same.
Q:What is the difference between steel strip and coil?
What do you think of rolling mills, not money ah, rolling strip is a small rolling opportunities, can be cheaper than rolling coil, and this cost should be spread to each product above, there are other what, like the cost of sharing ah.
