Double Skin Color Steel Sandwich Panel is designed for steel structure wall and roof systems requiring thermal insulation, structural stability, and fast installation, widely used in industrial and commercial buildings such as factories, warehouses, and logistics facilities.
Key Features
- Not Easy to Deform
Upper and lower color-coated steel sheets form a rigid shell, improving overall panel strength and resistance to deformation.
- Stable Thermal Insulation Layer
Core material reduces heat transfer through the building envelope, maintaining stable indoor temperature in industrial environments.
- Corrosion Resistance
Color-coated steel surface helps prevent rusting and protects the core from environmental exposure.
- High Structural Stability
Sandwich structure improves load distribution, suitable for wall cladding and roof systems under wind and snow load conditions.

FAQs
Q1: How to choose the core material for this panel?
EPS for cost-sensitive projects, PU/PIR for better insulation, and rock wool for fire-rated buildings.
Q2: Can the panel be used for both wall and roof?
Yes, but thickness and fixing method should be selected based on span and load requirements.
Q3: What is the maximum panel length?
Length is customized based on transport and installation conditions, usually within container limits.
Q4: How are panels connected on site?
Panels use tongue-and-groove joints or concealed fixing systems for quick alignment and secure installation.
Q5: Can surface color be customized?
Yes, color can be produced according to the RAL system to match project design requirements.
