Surface Material
Our PUR Cam Lock 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
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.

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
The surface material can also 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.
More About PIR/PUR Cam Lock Sandwich Panel
The effectiveness of polyurethane cam lock sandwich panels in cold storage applications lies in their unique structure and the properties of polyurethane foam. The core material, polyurethane, is a thermoset polymer that expands during the manufacturing process to form a dense, closed-cell structure. This structure traps air, which is a poor conductor of heat, providing excellent insulation.
When installed in a cold storage facility, these panels create a barrier that minimizes heat transfer from the external environment to the interior space. This is critical to maintaining low temperatures, as even small fluctuations can cause temperature-sensitive products to spoil. The outer metal layer not only provides structural support but also protects the foam core from physical damage and environmental exposure.
Key features of PUR/PU Cam Lock Sandwich panels include:
High thermal insulation value
Polyurethane foam is one of the materials with the highest thermal resistance value among thermal insulation materials, with a thermal conductivity coefficient (λ) of approximately 0.023-0.025 W/m·K. This minimizes heat transfer and ensures the refrigerated environment effectively maintains the required temperature.
Cam Lock Design
The cam lock mechanism enables fast and secure panel connection, ensuring a tight seal, minimizing air leakage and enhancing insulation performance.
Lightweight
Although polyurethane panels have strong insulating properties, they are lightweight and easy to handle and install. This feature reduces the overall structural load on the building, which is particularly beneficial when retrofitting existing structures.
Moisture-proof
The closed-cell structure of polyurethane foam makes it resistant to moisture absorption and prevents mold growth, which is crucial in refrigerated environments with high humidity.
