Product Overview
Color steel polyurethane sandwich panel is a factory-engineered composite panel consisting of two layers of color-coated steel sheet bonded to a rigid polyurethane foam core. The three-layer construction provides enclosure rigidity and high-efficiency thermal insulation in a single product.
Polyurethane foam features very low thermal conductivity among widely-used insulation materials. This allows thinner panels to achieve the same thermal resistance as thicker mineral wool alternatives, saving building space and reducing structural weight.
Typical applications include cold storage facilities, temperature-controlled warehouses, industrial plant envelopes, and commercial roof and wall systems.
Panel thicknesses range from 30 mm to 200 mm, with effective widths of 1,000 mm and custom lengths up to 12,000 mm. Steel gauges from 0.4 mm to 0.8 mm are available. Core density and final dimensions are confirmed per project drawings. If you have specifications ready, our technical team can review your documentation to assess production feasibility.
Product Features
1. High-efficiency thermal insulation
Polyurethane foam features very low thermal conductivity among widely-used insulation materials. This allows the panel to deliver high thermal resistance with reduced thickness compared to many other core materials.
2. Composite construction
The rigid polyurethane core is continuously bonded to the steel facings during production, creating a single composite panel with stable thermal performance across the entire surface.
3. Enclosure rigidity
The steel facings contribute to the panel's cladding performance, allowing use as wall and roof cladding. The composite construction provides reliable enclosure stability for building envelopes.
4. Fast installation
The large-format panels are crane-lifted and fixed directly to the building frame with self-drilling screws. Interlocking edges are designed for effective weather resistance when installed per project specifications, and installation labor is significantly reduced compared with traditional built-up systems.
Facing and Coating Options
Color steel sandwich panels are available with various surface finishes and coating systems. Available options include:
| Option Type | Description |
|---|---|
| Standard Color Coating | Polyester or PVDF coating in standard RAL colors; colors confirmed per project |
| Anti-Corrosion Coating | Enhanced coating system for aggressive environments |
| Embossed Finish | Embossed surface texture for reduced glare and improved aesthetics |
| Perforated Facing | Perforated steel sheet for acoustic applications (functional performance to be confirmed by project designer) |
Please specify the required facing type and coating when submitting your inquiry.

Note: Our service executes fabrication strictly to customer-provided specifications. The product is supplied as a building component; final design, panel selection, fixing systems, fire ratings, thermal calculations, and code conformity must be verified by the project owner and their qualified engineering team. We do not provide engineering certification or compliance validation for specific applications.
Customization and Packaging
Panel thickness, core density, length, steel gauge, coating system, color, and packaging are all configurable per order specifications and finalized before production.
Panels are dispatched in protective stacks suited to their size and quantity. Container stowage plans and stacking arrangements are determined per order to avoid transit damage and control freight costs.
MOQ: Quoted based on specifications and order volume
Sample availability: Panel samples are available on customer's request
Production lead time: Determined by specifications and order size
Packaging: Protective stacks / plastic wrapping / steel banding / final packaging arranged per order
OEM marking: Offered upon request (labeling or paint marking)
FAQ
Q1. How does polyurethane compare to other core materials?
Polyurethane features very low thermal conductivity. Thinner panels achieve equivalent thermal resistance compared with thicker rock wool or glass wool, saving space and reducing load.
Q2. What panel thickness should I choose for cold storage?
Thickness depends on temperature differential, climate, and refrigeration design. Refer to your project's thermal calculations for specific guidance.
Q3. Is polyurethane suitable for high-temperature applications?
Polyurethane foam core is rated for continuous service up to approximately +120°C. This refers to the foam core only—the complete panel assembly is limited by adhesives and steel facings. Operating-temperature evaluation should be completed by your project engineer.
Q4. Can panels be supplied in custom colors?
Yes. Standard RAL colors are available, and custom colors can be matched subject to coating availability. Color samples are confirmed prior to production.
Q5. Are the panels suitable for exterior roof applications?
Yes. Panels are designed for both wall and roof cladding. Joints and fixing systems should be selected based on project wind load and weatherproofing requirements.
Q6. How do polyurethane panels compare to spray foam?
Panels are factory-made with consistent density and protective steel surfaces on both sides. Spray foam is applied on-site and requires additional cladding. Panels suit new construction; spray foam suits retrofits and irregular cavities.
