Surface Material
Our PIR sandwich panel have multiple customizable surface steel material and color choices such as PPGI, Stainless steel, embossed aluminum etc. Their durability, moisture resistance and chemical resistance further enhance their appeal.
PPGI (Preprinted Galvanized Iron)
PPGI, or Preprinted Galvanized Iron, is a versatile metal material widely used in construction and manufacturing. It features a galvanized steel base that is coated with a layer of paint for excellent corrosion resistance and durability. Key features include its lightweight nature and its availability in a variety of colors and finishes for aesthetic customization. PPGI is also very environmentally friendly as its production process produces less waste. PPGI has a long service life and minimal maintenance requirements, making it ideal for roofing, wall cladding and other applications.

Extra Coating
PPGI can also be enhanced with various advanced coatings to improve its performance and durability.
Typical coating includes:
- 1. PVDF (Polyvinylidene Fluoride): Known for its exceptional resistance to UV radiation, chemicals, and weathering, PVDF provides a glossy finish that retains color vibrancy over time. This makes it ideal for outdoor applications, particularly in architectural projects.
- 2. HDP (High-Durability Polyester): HDP coatings offer superior durability and scratch resistance, making them suitable for high-traffic areas and industrial environments. They protect against corrosion and environmental factors, extending the lifespan of the material.
- 3. EP (Epoxy Polyester): This coating combines the benefits of epoxy and polyester, providing excellent adhesion and resistance to chemicals and moisture. EP coatings are ideal for indoor applications and environments where chemical exposure is a concern.
These advanced coatings significantly enhance the functionality and longevity of surface, making it a preferred choice for various applications in construction and manufacturing.
PIR sandwich panels combine excellent thermal insulation, cost-effectiveness, safety, and versatility, making them the first choice for modern construction needs. Their core competitive advantage is the ability to deliver long-term energy savings while ensuring structural integrity and safety.
