EPS Sandwich Panel Specifications
Core Material Expanded Polystyrene EPS
Our EPS insulated sandwich panels use a rigid Expanded Polystyrene (EPS) core. EPS is lightweight, closed-cell foam that offers reliable thermal insulation, stable performance, and moisture resistance. It is ideal for both roof and wall panel systems in commercial, industrial, and cold storage applications.
Key EPS Core Benefits:
- Excellent thermal insulation (low thermal conductivity)
- Resistant to moisture and mold growth
- Lightweight for easier handling and installation
- Stable performance over time without sagging or settling
Cover Material Options
We offer multiple facing options to meet different environmental and strength needs:
- Galvanized steel sheets for corrosion resistance and durability
- Color-coated steel sheets for visual appeal and extra protection
- Aluminum sheets for lightweight applications and high corrosion environments

Manufacturing and Quality Control Process for EPS Sandwich Panels
Raw Material Sourcing
As a leading China EPS sandwich panel manufacturer, Shanghe sources only premium-grade expanded polystyrene (EPS) from trusted suppliers. The steel skins—whether galvanized, pre-painted color-coated, or aluminum—are procured from mills that meet ISO and CE standards. This ensures each panel has a consistent EPS core density and durable metal exterior for long-term performance.
Production Line Technology
We operate fully automated continuous production lines in our modern EPS sandwich panel factory. The process ensures:
- Consistent EPS core bonding with metal sheets
- High-speed precision cutting for custom sizes without edge defects
- Uniform thickness with tight tolerances
- Smooth, even coating finishes on all panels
Our technology covers both roofing and wall-type EPS insulated sandwich panels for commercial, industrial, and cold storage usage.
Quality Testing Procedures
Every EPS panel batch undergoes strict in-house testing to meet U.S. and international standards:
- Mechanical Strength Test – Checks load-bearing capacity for structural use
- Thermal Performance Test – Measures insulation efficiency (R-value, thermal conductivity)
- Fire Resistance Test – Ensures compliance with safety codes for building applications
- Surface Adhesion & Finish Inspection – Guarantees paint quality and lamination durability
Our QC team uses SGS-certified measuring equipment to verify all parameters before shipment.
Packaging Handling and Logistics
To protect panels during transport, we use:
- PE film wrapping for moisture protection
- Foam corner guards to prevent dents or edge damage
- Palletized bundling for easy forklift handling
For U.S. buyers, we offer export-ready packaging with fumigation-compliant wooden pallets. Panels are shipped via sea freight or intermodal transport, ensuring safe delivery to your project site, whether it’s a prefabricated building, cold storage facility, or warehouse expansion.

FAQs about Shanghe EPS Sandwich Panels
What is an EPS Sandwich Panel
An EPS sandwich panel is a lightweight, insulated building panel made with an expanded polystyrene (EPS) foam core between two layers of metal, usually color-coated steel, galvanized steel, or aluminum. It’s designed to provide thermal insulation, structural strength, and a finished surface in one product.
Common uses include cold storage facilities, warehouses, prefab buildings, roofing, and wall cladding.
How Shanghe EPS Panels Compare with Other Core Materials
Shanghe’s EPS panels deliver a cost-effective, highly lightweight, and easy-to-install option compared to other cores like polyurethane (PU) or rock wool.
- Better value for general insulation where extreme fire resistance is not the main requirement
- Lower weight for easier transport and installation
- Good thermal performance for moderate to cold climates
- Faster production & delivery due to simpler processing compared to PU or PIR panels
For projects needing ultra-high fire resistance, mineral wool cores may be considered. But for most commercial, industrial, and agricultural buildings in the U.S., EPS cores meet performance and budget needs effectively.
Are Customized Panels Available
Yes. Shanghe provides custom EPS sandwich panel manufacturing with options for:
- Length, width, and thickness according to building design
- Panel colors matched to project branding or aesthetic needs
- Surface coatings for corrosion resistance, UV stability, or enhanced hygiene
- Special panel types for cold rooms, roofing systems, or soundproofing applications
Typical Lead Time for Orders
Lead times depend on panel size, quantity, and customization level:
- Standard sizes & colors: usually 7–10 days after order confirmation
- Custom sizes/colors: typically 10–15 days
- Large export projects: may require additional production and shipping time
Shanghe’s high-capacity production lines help ensure a consistent and reliable supply, even for bulk orders.
How to Maintain EPS Sandwich Panels
EPS panels require minimal upkeep, but following basic care helps extend lifespan:
- Clean periodically with mild soap and water to remove dirt and debris
- Inspect joints and fasteners for any damage or loosening
- Avoid high-pressure washing directly at seams to prevent water infiltration
- Touch up scratches on coated steel surfaces to avoid corrosion
- Keep panels free from prolonged contact with strong solvents or chemicals that can damage the EPS core
