Aluminum Sandwich Panel

Aluminum sandwich panels combine two outer face sheets bonded to a central aluminum honeycomb core, utilizing hexagonal geometry to distribute loads while delivering high strength and stiffness with minimal weight. The panels provide long-term dimensional stability and low thermal expansion, making them suitable for applications requiring performance under varying environmental conditions.

The exceptional strength-to-weight ratio significantly exceeds that of traditional solid materials, with notable compressive and tensile strength contributing to structural integrity. The aluminum core, available in various cell sizes and densities, provides specific mechanical and thermal properties, including energy absorption and formability for complex shapes. The bond between core and skins resists delamination, ensuring durability.

These panels serve aerospace, marine, automotive, and construction industries in applications including aircraft interiors, marine paneling, architectural cladding, vehicle body panels, and industrial components. Their lightweight properties and structural performance make them ideal where reducing dead load is essential without compromising strength or durability.

Available thicknesses range from 10mm to 75mm or more, with widths extending to 3.2 meters. Computer Numerical Control (CNC) machining enables precise cutting, milling, and drilling. The panels can be cut using cut-off wheels or tungsten carbide saber saws, and maintain high flatness and dimensional tolerance after manufacturing.

Aluminum Foam Core Panel

Lightweight sandwich panel with two aluminum skins laminated to a foam core for thermal insulation and reduced dead load. Offered in multiple foam options and thickness ranges, it suits façades, partitions, roofing, and cold-room envelopes where insulation and easy fabrication matter most.

Aluminum Honeycomb Panel

High-stiffness aluminum sandwich panel using an aluminum honeycomb core for superior rigidity at low weight. Compared with foam-core types, it prioritizes flatness, strength, and impact resistance, making it ideal for large-format cladding, transportation interiors, and applications demanding high strength-to-weight.

Aluminum PET Sandwich Panel

Aluminum-skinned panel with a PET foam core, balancing insulation, dimensional stability, and mechanical strength. Versus PU or XPS, PET typically targets a more structural feel and better temperature tolerance, making it a solid choice for façades and partitions needing strength without heavy weight.

Aluminum PU Sandwich Panel

Aluminum sandwich panel with a PU foam core focused on maximum thermal insulation and energy efficiency. Compared with PET or PVC foam versions, it is often chosen when insulation performance is the top priority, such as cold storage, insulated enclosures, and climate-controlled building envelopes.

Aluminum PVC Sandwich Panel

Aluminum composite sandwich panel with a PVC foam core, valued for processing friendliness and stable performance. Compared with PU, it emphasizes balanced insulation and workability; compared with XPS, it often targets robust panel feel for interior partitions, signage, and architectural cladding systems.

Aluminum XPS Sandwich Panel

Aluminum-faced panel with an XPS foam core designed for strong insulation and moisture resistance. Compared with PU, it commonly targets a cost-effective insulation build; compared with PET, it leans more toward insulation over structure, fitting roofs, wall cladding, and refrigerated-room linings.

Aluminum Sandwich Panel Selection & Engineering Guide

Selecting the right specification for Aluminum Sandwich Panel depends on matching structural load requirements, environmental exposure, and thermal R-value insulation goals. At RaxPanel, our engineering team manufactures high-performance composite panels to deliver durable, moisture-resistant, and energy-efficient solutions for industrial and commercial projects worldwide.

💡 Pro Tip: Delamination Prevention Under Thermal Cycling
At RaxPanel, we utilize automated vacuum lamination with high-performance two-component polyurethane adhesives to ensure a bond strength that absorbs differential thermal expansion without micro-delamination.

1. How to Choose the Right Skin Alloy and Thickness

Outer skin selection governs mechanical impact resistance, corrosion barriers, and structural stiffness across different operating environments.

2. How Well Does the Core Insulate and Withstand Heavy Loads?

The core material handles shear stress and maintains thermal R-value insulation across operating temperature ranges:

Performance Metric	RaxPanel Engineering Standard	Application Advantage
Outer Skin Spec	Pre-Painted Aluminum / GRP Sheet (0.3mm – 2.0mm)	High tensile strength and corrosion resistance
Thermal Conductivity	~ 0.020 – 0.038 W/m·K	Consistent R-value insulation & energy savings
Bonding Adhesive	Two-Component Polyurethane / Epoxy Adhesive	Delamination-free performance under freeze-thaw cycles

3. Which Surface Finish Will Protect Your Panels for 20+ Years?

Factory roller coating specifies long-term color stability, UV protection, and resistance against industrial pollutants or marine salt spray.

4. How Fire-Safe and Soundproof Are These Panels?

🛡️ Compliance & Acoustic Isolation:

Fire Safety: Formulations comply with EN 13501-1 Class B-s1,d0 and GB8624 Class B1 building fire safety standards.
Sound Damping: Composite core attenuates noise transmission by 24 dB to 30 dB relative to solid metal sheets.

5. Where Are Aluminum Sandwich Panels Most Commonly Installed?

🏢 Commercial & Industrial Buildings

Exterior wall cladding, cleanroom partitions, and insulated roof envelopes.

🚚 Cold Storage & Transport Fleets

Refrigerated truck bodies, cold storage rooms, and RV composite walls.

6. How to Cut, Groove, and Seal Edges During Installation

Panels process easily on-site using standard CNC machinery, routers, or specialized edge profiles for airtight moisture sealing.

Frequently Asked Questions (FAQS)

1. What are the standard panel thicknesses, maximum lengths, and width options available for Aluminum Sandwich Panels?

Standard panel thicknesses range from 10mm up to 150mm. Standard widths include 1000mm, 1220mm, and 1500mm, with maximum single-sheet lengths up to 5800mm (5.8m) to fit ocean freight container shipping dimensions.

2. What are the primary engineering benefits of using Aluminum Sandwich Panels?

Aluminum Sandwich Panels deliver an exceptional stiffness-to-weight ratio, rot-proof moisture resistance, reliable thermal insulation, and dynamic fatigue endurance for high-stress applications.

3. How do these composite panels perform under high humidity and outdoor weathering?

The closed-cell core prevents water logging and condensation absorption, while pre-painted skins provide a 20+ year weatherability barrier against UV degradation.

4. What fire safety ratings and quality certifications do these composite panels meet?

Flame-retardant formulations meet EN 13501-1 Class B-s1,d0 and GB8624 Class B1 fire performance standards. Manufacturing quality is governed under ISO9001 management systems, with raw material performance verified under SGS and CE testing.

5. What surface coating options are available for exterior UV protection?

70% PVDF Fluorocarbon Coating PVDF coating provides a 20+ year exterior weatherability warranty against UV fading and acid rain. FEVE offers high gloss retention, while PE coating is cost-effective for indoor partitions.

6. Can these composite panels be CNC grooved, bent, or edge-sealed on-site?

Yes. Pre-painted skins can be V-grooved at 90° or 135° on the reverse side using standard CNC routers or hand tools, allowing manual edge folding into architectural cassettes without surface paint cracking.

7. How are large panel shipments packaged to prevent freight damage during ocean transit?

Panels are packed with protective PE film on both skins, separated by inter-sheet foam layers, and secured on heavy-duty export wooden pallets or CKD steel crates to prevent shipping damage during 20ft and 40ft container freight.
