PUR sandwich panels consist of a core made of polyurethane foam, sandwiched between two outer layers, usually made from sheet metal such as galvanized steel or aluminum. Panel thickness can vary, typically 50mm to 200mm, depending on specific insulation requirements. The polyurethane sandwich panels are engineered to provide good insulation, structural integrity, and versatility, making them ideal for a variety of refrigeration applications.
The PUR sandwich panel are an excellent choice for cold storage insulation, such as food or drug storage, cold chain logistics and industrial refrigeration. It features in energy efficiency, versatility, easy installation as well as beautiful appearance.
Our PUR Sandwich panel has the thickness choice from 50mm to 200mm, and can be customized in length and surface steel finish to meet specific project requirements.

The Split Joint PUR sandwich panels are widely used in industrial, commercial, and agricultural buildings, including warehouses, cold storage facilities and manufacturing plants. Their ease of installation and low maintenance requirements make them a cost-effective option for modern construction projects, helping to increase sustainability and efficiency.
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, 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 has a variety of color finishes, we provide customized color service for whatever color you need.
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.).
PPGI can also be enhanced with various advanced coatings to improve its performance and durability. Typical coatings include:
