More Colors
PPGI has a variety of color finishes, we provide customized color service for whatever color you need.
Other Surface Material
To obtain better or specific function, other surface materials can also be customized — such as Stainless Steel (SUS304 / SUS201), Aluminum, or other alloy (Zinc, Magnesium, Titanium, etc.).
Ti-Mg-Zn-Al Alloy
Embossed Aluminum
Stainless Steel (SUS304)
Extra Coating
PPGI can also be enhanced with various advanced coatings to improve its performance and durability. Typical coatings include:
-
🛡️
1. PVDF (Polyvinylidene Fluoride): Exceptional resistance to UV radiation and weathering, retaining color vibrancy over time.
-
🔨
2. HDP (High-Durability Polyester): Superior durability and scratch resistance, suitable for industrial environments.
-
🧪
3. EP (Epoxy Polyester): Excellent adhesion and resistance to chemicals and moisture, ideal for indoor chemical exposure.
PIR sandwich panels combine excellent thermal insulation, cost-effectiveness, safety, and versatility. Their core competitive advantage is the ability to deliver long-term energy savings while ensuring structural integrity and safety.
