Dx51D Color Coated Steel Roll PPGI Prepainted Galvanized Steel Coil
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.
Production Process
1. raw material steel coil
2. cold rolled steel coil
3. Zinc or Alu-Zinc coating
4. annealing
5. color coated steel coil
6. packing
Features
1. Anti-corrosion and moisture-proof construction convenience
2. Good ductility and strong moisture-proof function.
3. 0.1-0.15mm kraft paper has high strength bonding.
4. Liner and top grade stadiums can be composited with kraft paper.
There are two processes for covering kraft paper on the surface of aluminium roll:
First: The kraft paper used on the surface is self-adhesive bonded by glue, which has the advantages of high production efficiency, timely delivery and low production cost.
Two: The kraft paper and aluminium roll are bonded together by heating.
After covering kraft paper, the aluminium roll can be further processed to make embossed aluminium roll.
