Color Coated PPGI Prepainted Galvanized Steel Coil For Corrugated
Roofing
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)

Processes of Hot Dipped Galvanized Steel Coil
Hot Dipped Galvanized Steelis widely used in auto, household
electrical appliance, IT, adnvaced building materials industries,
etc.The process of producing hot dipped galvanized steel is: Cold
Rolled Full Hard - Payoff Reels - Degreasing - Annealing - Zinc
Coating - Tension Leveling - Straightedge Forming - Chromeate or
Oil.
| Characteristics of the Continuous Galvanizing Line |
| • Adopt roll-painting-chromated technology, ensure the Cr Free and
envirinmentally-friendly process. |
| • High-level automatic control system ensures the efficiency and
product quality. |
| • Product is able to be well shaped after tension leveling and
straight forming. |
| • GI production line equipped with chromated, oiled and anti-finger
print facilities can reach customers' requirements. |
| • Zinc coating control system and technology imported from France
guarantees the uniformity of zinc coating. |
| • The USS method applied in galvanizing thchnology ensures the high
quality of adhesion and surface treatment. |
