Introduction: Wuxi Gotele Metal produces the widest range of Prepainted Galvanized Steel Coil& Sheet , Pre-coated Metal Sheet,
laminated steel, pre-coated steel, and anti-fingerprint steel.
PPGI is produced by coating two or more layers paint applied on Cold-Rolled, Galvanized Steel, Electrolytic Galvanized Steel,
base-steel, and then cut into sheets. It is also called prepainted steel, pre coated metal sheet.

Production Facility of Prepainted Galvanized Steel? Coil:
Pay-off Section
The operating principles and functions are similar to the galvanizing process, except that it uses a joiner to fasten the steel sheets together.
Clean, Pre-treatment and Chemical Coating
The GI coil is cleaned at the degreaser tank, where oil and dust are removed by chemical means. The white rust formed on the surface can be removed at the brush assembly. The clean coil will then be coated with conditioner and chromate at the conditioner and chromate tank respectively, to provide better adhesion and corrosion resistance ability.
Prime and Finish Coating
A basic layer of paint, called primer, is applied on the chemical coater in order to strengthen the corrosion resistance and paint adhesion ability. The requested colours and specifications of paint will be applied at both the top and bottom of the primer coated coil to complete the painting work.
Prime and Finish Oven
The primer coating is further cured at the primer oven and cooled at the primer water quench to ensure the painted coil is completely cured. Similarly, the finish oven and finish water quench also serve to ensure that the paint applied is completely cured and cooled.
Production Line of Prepainted Galvanized Steel? Coil:
A typical Horizontal PPGI Line would comprise with the following steps:
