DX51D SGCC color coating Galvanized steel coil
PPGI is pre-painted galvanised iron, also known as pre-coated steel, coil coated steel, color coated steel etc., typically with a hot dip zinc coated steel substrate. The term is an extension of GI which is a traditional abbreviation for Galvanized Iron.
Using Hot Dip Galvanized Steel Coil as the substrate, PPGI is made by first going through surface pretreatment, then the coating of one or more layers of liquid coating by roll coating, and finally baking and cooling. The coatings used including polyester, silicon modified polyester, high-durability, corrosion-resistance and formability

High strength tension hot rolled pickled oiled S235 S355 S420 S550 structural carbon steel slitted strip coil
High strength tension hot rolled pickled oil S235 S355 S420 S550 carbon steel slitted strip coil
S355 grade steel is a medium tensile, low carbon manganese steel which is readily weldable and possesses good impact resistance (also in sub-zero temperatures).
What is the difference between S275 and S355 steel?S275 provides a lower strength (than S355) but has good machinability and can be welded. The average minimum yield for S275 steel is 275 N/mm² giving its name: S275. S355 is often used in the most demanding environments such as the offshore industry.EN10149 S420MC steel plate/sheet,EN10149 S420MC steel plate/sheet, under EN standard, we can regard S420MC steel plate/sheet as high yield strength steels for cold-forming steels.
S420MC steel plate is mainly used as high yield strength steels for cold-forming steels.
The EN10149 S420MC steel is equivalent to SEW092 QStE420TM, NFA E420D, UNI FeE420TM, ASTM X60XLK and BS HR50F45 steel grades.

According to the customer’s requirements Package: Standard export package (Plastic film in the first layer,second layer is Kraft paper. Third layer is galvanized sheet) Application: Industrial panels, roofing and siding for painting Applications of Our Galvanized Steel Coils :
1.Construction and building: roofing; ventilating duct; handrail; partition panel,etc.
2.Further processing: coating base plate.
3.Electric appliance: refrigerator; washing machine; recorder; microwave, etc.The hot dip process includes passing the steel through a molten zinc bath, and the electro galvanizing process includes applying zinc through electrolytic treatment. 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
