China Manufacturer JIS ASTM DX51D AZ150 Galvalume Cold Rolled Sheets Coils Hot Dip SGCC Z275 Galvanized Steel Strip GL GI
Galvanized sheet refers to the steel plate coated with a layer of zinc. Galvanizing is an economical and effective antirust method which is often used. About half of the world’s zinc production is used in this process.
Galvanized Steel Coils have gone through a chemical process to keep them from corroding. The steel gets coated in layers of zinc because rust won’t attack this protective metal. For countless outdoor, marine, or industrial applications, galvanized steel is an essential fabrication component. The principal method of making steel resist corrosion is by alloying it with another metal, zinc. When steel is submerged in melted zinc, the chemical reaction permanently bonds the zinc to the steel through galvanizing. Therefore, the zinc isn’t exactly a sealer, like paint, because it doesn’t just coat the steel; it actually permanently becomes a part of it.

Hot Rolled Zinc Galvanized Steel Sheet Zinc Coated Steel Plate
Hot-dip galvanizing is the reaction of molten metal with an iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle iron and steel parts first. In order to remove iron oxide on the surface of iron and steel parts, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium chloride and zinc chloride.And then sent to the hot-dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

soft forming quality Electro hot dip galvanized steel plate SECC JIS G 3313 Electro-Galvanized Commercial Cold Rolled
soft forming quality Electro hot dip galvanized steel plate SECC JIS G 3313 Electro-Galvanized Commercial Cold Rolled
Electro Galvanized Steel(EGI) EGI is made in the way of electro galvanizing zinc over cold rolled steel. This product with high corrosion resistance has less coating than GI steel but features even coating thickness, good surface, and coating at a low temperature
SECC steel is electro-galvanized commercial quality cold rolled steel which is basically cold rolled and then coated with zinc in an electro-galvanizing line. SECC is a material grade and designation defined in JIS G 3313 standard. It is a low-cost steel metal grade with improved thermal conduction that is mostly utilized for the casings of computer and other electronic accessories. As a basic Zinc-Coated Carbon Steel it can be enumerated in mild steel which is processed under electro galvanization, unlike the SGCC steel which is processed hot-dip galvanized steel.
The based metal is actually made up of commercial quality cold rolled steel but the coating is made up of zinc through electro galvanization process unlike the hot-dip galvanized steels. Following forming operations can be performed on this type of steel:
- Pressing
- Blanking
- Shaping
- Lancing
- Piercing
- Notching
- Stamping
However, any specific forming operation should be properly investigated and testing should be performed before the execution.
Following are the available forms of SECC steels in the global market:
- Galvanized Coils
- Slit Edge Galvanized Coils
- Cut to Length Galvanized Sheets

As a result, the zinc layer is firmly adhered to the base metal through the iron-zinc bonding layer. Our hot-dip galvanized products are manufactured in accordance with specifications, and our electro-galvanized products comply with the specifications.
Galvanizing is one of the most effective and economical methods for protecting bare steel from corrosive environments. Zinc is not only a barrier between steel and the environment, but also sacrifices itself to protect the steel plate below. When two different metals are in contact and coupled with water and oxygen, sacrifice or current protection occurs. Zinc preferentially corrodes iron in steel. This protection prevents corrosion of the steel in areas not covered by zinc. Therefore, the diffusion of corrosion from cutting edges, drilling holes, etc

ASTM 653 Prepainted PPGL DX51D DX52D SGCC Galvanized Steel Sheet Coil
Galvanized steel is a hot-dipped coated metal that provides customers with better resistance to corrosive environments.
To create galvanized steel, cold rolled steel is submerged into a molten zinc bath, known as the hot-dip process (galvanization can also be achieved through continuous galvanizing). When the material is removed from the zinc bath and cooled a reaction to the oxygen in the air occurs. The reaction causes the zinc coating to become part of the steel creating the well-recognized spangled finish.
