High Quality ASTM/Cold Rolled Galvanized Steel Coil for Metal Iron Roofing Sheet Price
Alvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metal, alloy or other materials to play the role of aesthetics and rust prevention. The main method used is hot galvanizing.
For galvanized coils, the thin steel plate is immersed in the molten zinc bath to make the surface of the zinc thin steel plate adhered. It is mainly produced by continuous galvanizing process, that is, the coiled steel sheet is continuously immersed in a galvanizing tank with molten zinc to make galvanized steel sheet; alloyed galvanized steel sheet. This kind of steel plate is also manufactured by hot dipping method, but immediately after leaving the tank, it is heated to about 500°C to form an alloy film of zinc and iron. This galvanized coil has good paint adhesion and weldability.
Alvanized steel coil is mainly used in construction, home
appliances, automobiles, machinery, electronics, light
industry,signage industry etc.Galvanized sheet is mainly
used: a large number of galvanized sheet plate used in
automobile manufacturing, cooler, construction,ventilation
and heating facilities and furniture manufacturing and other
fields.
Galvanized become important steel anticorrosion method, not
only bacause the zinc can be formed in the steel surface
protective layer of dense, but also because of the zinc has
the effect of cathodic protection, when the galvanized layer
damage, it can still through the cathodic corrosion protection
to prevent the iron base.
Hot-dip galvanized coils can be divided into hot-rolled
galvanized coils and cold-rolled hot-dip galvanized coils,
which are mainly used in construction, home appliances,
automobiles, containers, transportation and household
industries. Especially steel structure construction, automobile
manufacturing, steel silo manufacturing and other industries.
Their main features are: strong corrosion resistance, good
surface quality, conducive to deep processing, economical
and practical, etc.
Galvalume steel coils used galvalume/aluzinc (AZ20 -275gsm) steel coils as the basic raw materail. After pretreatment (the surface of the basic raw materail is cleaned to remove impurities, degreasing, and undergoes composite oxidation and passivation treatment), the surface is coated with PE. SMP, PVDF paint is then baked and solidified. It is more suitable for applications in corrosive and coastal areas.

Color steel coil is a kind of composite material, also known as color coated steel plate. It is made of strip steel after continuous surface degreasing and phosphating and other chemical transfer treatments on the production line, and then coated with organic paint and baked.
Substrate Type
1.Hot-dip galvanized color coated steel sheet(pre-painted
galvanized steel sheet)
The product obtained by coating an organic coating on a hot-
dip galvanized steel sheet is a hot-dip galvanized color-
coated plate.
In addition to the protective effect of zinc, the hot-dip
galvanized color-coated sheet also protects against rust and
has a longer service life than hot-dip galvanized sheet;
2.Hot-dip aluminum-zinc color coated sheet(pre-painted
gavanized steel sheet) Hot-dip aluminum-zinc steel sheets
can also be used as color-coated substrates (55% AI-Zn and
5% AI-Zn);
3.Electroplated zinc color coated sheet
The electro-galvanized sheet is used as the substrate, and
the product obtained by baking with the organic coating is an
electro-galvanized color-coated plate. It has a beautiful
appearance and excellent processing properties, and
therefore can be mainly used for home appliances, audio,
steel furniture, interior decoration, and the like.

chalking resistance, gloss retention, general flexibility, and
medium cost.
High Durability Polyester(HDP): Excellent color retention and
anti-ultraviolet performance, excellent outdoor durability and
anti-pulverization, good paint film adhesion, rich color,
excellent cost performance.
Polyvinylidene Fluoride(PVDF): Excellent color retention and
UV resistance, excellent outdoor durability and chalking
resistance, excellent solvent resistance, good moldability,
