Products Description
Polyurethane cam lock sandwich panels consist of a core made of polyurethane foam, sandwiched between two outer layers, which are typically made from sheet metal such as galvanized steel or aluminum. Panels are available in a variety of thicknesses, typically 100mm to 200mm, depending on specific insulation requirements.
The Joint & Connection
The cam-lock design with split joint of the cam-lock 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.

Frequently Asked Questions (FAQ)
What thicknesses are available for polyurethane cam lock sandwich panels?
Panels are available in thicknesses of 100mm, 120mm, 150mm, and 200mm. Custom thicknesses can also be arranged based on specific project insulation requirements.
What is the thermal conductivity of polyurethane (PUR) sandwich panels?
The core has a heat transfer coefficient (Ud,s) of ≤0.024 W/[m·K] and a thermal conductivity (λ) of approximately 0.023–0.025 W/m·K, providing industry-leading efficiency.
What surface materials can be chosen for PUR cam lock panels?
Options include PPGI, Stainless Steel (SUS304 / SUS201), Embossed Aluminum, and special alloys like Ti-Mg-Zn-Al, with surface thicknesses from 0.3mm to 0.8mm.
How does the cam lock joint system benefit the installation?
The split joint design allows panels to interlock securely without extra fasteners. This ensures an airtight seal, improves insulation, and significantly speeds up on-site installation.
Are these panels suitable for cold storage facilities?
Yes, their closed-cell foam core provides exceptional thermal insulation, resists moisture, and prevents mold, making them ideal for stable low-temperature environments.
What advanced surface coatings are available for durability?
We offer PVDF for UV/weather resistance, HDP for scratch/corrosion resistance in industrial areas, and EP for superior chemical and moisture resistance.
