Categories of Printed PPGI Steel Coil Paint Coating

1. Polyester (PE)
Polyester coating has a great adhesion performance, wide range of formability and outdoor durability, medium chemical resistance and is available at a low cost.

2. Silicon Modified Polyesters (SMP)
The SMP coating has a great rigidity, abrasion resistance and heat resistance. It also has an excellent external durability and pulverization resistance, as well as a gloss retention ability.

3. High-durability Polyester (HDP)
HDP coating has an excellent color retention ability and anti-ultraviolet performance. It has an excellent outdoor durability and pulverization resistance, as well as a great adhesion performance.

4. Polyvinylidene Fluoride (PVDF)
PVDF coating has excellent color retention ability, UV resistance, excellent outdoor durability and pulverization resistance, excellent solvent resistance, good formability, and dirt resistance. It is available in limited colors and costs more than our other PPGI coil coatings.


1. Longer service life in corrosive environment than galvanized steel coil.
2. Processability: Similar processability and spraying property to galvanized sheets.
3. Heat resistance: These steel sheets feature more discoloration resistance than galvanized steel sheets at high temperatures.
