PPGI Coil Production Process


Unrolling – Stitching machine – Entrance loop – Pretreatment – Initial coating – Bake – Cool down – Fine coating – Bake – Embossed film – Export loop – Inspection station – Cut – Coiling

In the above process, if the cleaning degreasing process is not handled well, the adhesion of the primer of the color coated plate to the galvanized sheet is not good, and it is easy to cause the topcoat of the color coated steel coil to fall off during the press forming process.

Prepainted Galvanized Steel Coil Structure

  • Top Finish Coating (PE/HDP/PVDF, etc.), When the thickness is above 20um, it can effectively prevent the damage of ultraviolet rays and harsh environments to the coating.

  • Primer Coating

  • Surface Treatment Layer(Chromate Coating)

  • Metallic Coated Layer (Zn, AL, 55%AL+Zn)

  • Steel Substrate (Cold Rolled Steel Sheet)

  • Metallic Coated Layer (Zn, AL, 55%AL+Zn, Sn, Cr, etc.)

  • Surface Treatment Layer (Chromate Coating)

  • Back Primer
