Key Product Lines
Thermoplastic Honeycomb Sandwich Panels (HolyPan® Series)
The HolyPan® thermoplastic honeycomb panel represents Holycore's flagship product line. It consists of a polypropylene (PP) honeycomb core laminated between fiberglass reinforced skins (FRP) or other reinforced face materials. The combination of a cellular core with high-strength skins yields a panel with:
High stiffness-to-weight ratio
Low water absorption and moisture resistance
Excellent chemical and corrosion resistance
High bending and compressive strength
Thermal stability across a wide working temperature range
These panels are widely used in applications such as truck body sidewalls, modular partitions, cold-chain vehicle interiors, caravan and RV body panels, and structural wall components.
XPS Core Sandwich Panels
To meet demands for thermal insulation and structural stability, Holycore also produces FRP + XPS sandwich panels, which integrate extruded polystyrene foam (XPS) as the core. These panels are particularly suited for cold-chain logistics, refrigerated vehicle walls, and modular buildings requiring both structural integrity and insulation performance.
Decorative Composite Panels (HexWood, HexMetal, HexStone)
Beyond structural boards, Holycore manufactures decorative lightweight composite panels that combine aesthetic surface finishes with thermoplastic cores:
HexWood – wood-style decorative panel with moisture resistance and lightweight design
HexMetal – metal-finish composite panel with corrosion-free, light mass
HexStone – stone-texture composite panel offering luxury visuals without heavy stone weight
These decorative panels expand lightweight sandwich panel technology into interior design, furniture components, retail fixtures, and architectural decoration.

Where Lightweight Sandwich Panels Are Making an Impact
The versatility of lightweight sandwich panels is reflected in a wide array of industry applications. Below are expanded insights into some of the most impactful domains:
Transportation & Commercial Vehicle Bodies
In truck, van, and specialty vehicle manufacturing, lightweight sandwich panels reduce vehicle weight, increase payload capacity, and improve fuel efficiency. Holycore's FRP honeycomb panels and thermoplastic cores deliver a combination of structural rigidity and moisture resistance, making them preferred for sidewalls, ceilings, RBC floors, and bulkheads.
Cold-Chain Logistics & Refrigeration
Cold-chain applications demand panels with both thermal insulation and structural integrity. Sandwich panels with XPS or foam cores and laminated skins provide low thermal conductivity, moisture resistance, and mechanical stability. Holycore's XPS sandwich boards are widely applied in refrigerated trucks, portable cold rooms, and insulated storage facilities.
Modular Construction & Prefabricated Buildings
Lightweight sandwich panels are fundamental to modular housing, container buildings, and portable offices. Panels equipped with decorative surfaces - including wood-style, metal-look, or stone-look finishes - offer architectural flexibility while maintaining structural performance.
Marine & Interior Structures
Marine environments demand corrosion-resistant, moisture-proof materials. Honeycomb panels with fiberglass skins and thermoplastic cores resist saltwater exposure and dimensional distortion, while supporting cabin partitions, furniture modules, and interior décor.
Industrial & Cleanroom Environments
Cleanrooms, laboratories, and pharmaceutical facilities require hygienic, easy-clean surfaces with controlled dimension stability. FRP sandwich panels with sealed cores and smooth finishes are ideal for chemical resistance and frequent cleaning.
Lightweight Sandwich Panels in China & Beyond
Several trends are shaping the future of lightweight sandwich panels:
Increasing Adoption of Thermoplastic Cores - thermoplastic honeycomb cores like PP and PET offer recyclability and repeatable thermoforming advantages over thermoset cores.
Multi-Functional Panels - the integration of thermal insulation, sound absorption, fire resistance, and surface protection in a single lightweight panel.
Customization & Modular Design - demand for tailored panel sizes, performance grades, surface textures, and engineered panel systems.
Green Building & Regulatory Compliance - recyclable cores and low-emission composites support sustainable construction goals.
Manufacturers that combine advanced materials science, scalable production processes, and global logistic support - like Holycore - are at the forefront of this evolution.
