Three types of galvanized steel coils 


All of our galvanized steel coils are made of Cold Rolled Steel.Cr steel coil products with good finishing and easily formed advantage can be widely used in Automobiles,Refrigerators,Washing machines,Industrial equipments, and all kinds of building materials.

Our compnay can manufacture three types of galvanized steel coils:


• Hot dipped Galvanized steel coil (SGCC,SGCD,SGCE)

• Electrogalvanized steel coil (SECC,SECD,SECE)

• Hot dipped Galvalume Steel Coil (GL)
