Aluminum PVC Sandwich Panel

The Aluminum Polyvinyl Chloride (PVC) Sandwich Panel combines two outer aluminum sheets with a rigid closed-cell PVC foam core. This three-layer structure delivers a high strength-to-weight ratio, making it well suited for applications where both stiffness and low weight matter.

The closed-cell PVC foam core provides structural stability, effective thermal insulation, and minimal water absorption. The panel resists moisture, corrosion, chemicals, and UV exposure, and machines easily with standard CNC equipment for custom shapes and cutouts. Additional properties include sound dampening and full recyclability of both aluminum and PVC components.

Common applications include marine cabin bulkheads, industrial partitions, equipment enclosures, transportation vehicle bodies, commercial building cladding, and signage. Full technical parameters are listed in the data sheet below.

Aluminum PVC Sandwich Panel Selection & Engineering Guide

When marine cabin bulkheads, industrial partitions, and equipment enclosures require high shear strength, rigid fastener retention, and rot-proof moisture resistance, PVC foam cores excel. Aluminum PVC Sandwich Panels bond durable aluminum alloy skins onto a rigid closed-cell PVC foam core. At RaxPanel, our engineering team manufactures these composite panels to provide superior mechanical rigidity, high shear resistance (2.0 to 4.5 MPa), and long-term durability under demanding industrial and marine operating conditions.

💡 Pro Tip: High Core Shear Strength for Fastener Retention
In structural marine bulkheads and heavy equipment partitions, lower-density foams can crush or strip out when securing screws and mounting brackets. RaxPanel offers high-density PVC foam cores (120 – 250 kg/m³) that deliver strong shear modulus and screw pull-out strength, eliminating localized core crushing during installation.

1. How to Select Marine-Grade Aluminum Alloys and Skin Thickness

Selecting the appropriate aluminum skin alloy (0.3mm to 2.0mm thickness) determines structural strength and environmental protection:

5005 / 5052 Marine Alloy (Al-Mg): Exceptional resistance to salt spray and saltwater corrosion; the mandatory choice for marine cabin partitions, ship bulkheads, and offshore facilities.
3003 Alloy (Al-Mn): High tensile strength and impact resistance; ideal for commercial building wall cladding, industrial machinery enclosures, and transport walls.
1100 / 1050 Alloy: Excellent ductility; specified for decorative interior wall partitions, ceiling panels, and indoor signage.

2. Why High-Density PVC Foam Outperforms in Shear Strength and Screw Holding

Closed-cell PVC foam core delivers high physical performance for structural sandwich construction:

Performance Property	RaxPanel PVC Core Standard	Engineering Advantage
PVC Core Density Range	60 kg/m³ to 250 kg/m³	Tailored options from lightweight interior partitions to heavy structural bulkheads
Core Shear Strength	2.0 MPa to 4.5 MPa	High fatigue resistance preventing core delamination under dynamic loads
Water Absorption Ratio	< 1.5% (Volumetric)	Impervious to water logging, rot, and mold growth in wet marine cabins
Thermal Conductivity (λ)	~ 0.033 – 0.038 W/m·K	Effective thermal R-value insulation for climate-controlled marine spaces

3. Which Surface Finish Will Protect Your Panels Against Marine Salt Spray?

Surface roller coatings guarantee long-term color stability and protection against harsh atmospheric exposure:

PVDF Coating (70% PVDF Fluorocarbon Coating): 20+ Year exterior warranty against UV fading, chalking, and coastal marine atmosphere.
FEVE Coating: High gloss retention and vivid color durability for architectural features.
PE Coating: Cost-effective finish for indoor wall partitions, available in wood grain, stone, and solid metallic tones.

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

🛡️ Safety & Acoustic Performance:

Fire Ratings: Flame-retardant PVC core formulations meet EN 13501-1 Class B-s1,d0 and EN 13501-1 Class B1 fire performance standards.
Acoustic Isolation: High-density PVC foam absorbs vibration and dampens structural sound transmission by 24 dB to 30 dB relative to single metal sheets.

5. Where Are Aluminum PVC Panels Most Commonly Installed?

🚢 Marine Cabin Bulkheads & Ship Interiors

Saltwater-resistant 5052 aluminum skins with rigid PVC core for lightweight, rot-proof ship interior walls.

🏢 Industrial Enclosures & Cleanroom Walls

High shear strength panels for machinery housings, cleanroom partitions, and commercial wall cladding.

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

Aluminum PVC panels process smoothly on-site using CNC machinery or standard tools:

V-Groove Corner Folding: Cut 90° V-grooves into the reverse aluminum skin to fold clean 90-degree corners without cracking surface paint.
Edge Protection: Edge sealing options include open edges, folded skin edges, or aluminum extrusions to prevent moisture ingress.

Frequently Asked Questions (FAQS)

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

Standard panel thicknesses range from 10mm up to 120mm. Standard widths include 1000mm, 1220mm, and 1500mm (with custom widths up to 2600mm), with maximum single-sheet lengths up to 5800mm (5.8m) to fit ocean freight container shipping dimensions.

2. Why is rigid PVC foam core preferred for marine cabin partitions and ship bulkheads?

Rigid PVC foam provides excellent moisture resistance (<1.5% water absorption), high shear strength (2.0-4.5 MPa), and rot-proof durability in salty, humid marine environments, while significantly reducing vessel top-weight compared to solid steel bulkheads.

3. What PVC foam core density options are available for different structural loads?

Core densities range from 60 kg/m³ for lightweight interior partitions up to 120–250 kg/m³ for high-load structural bulkheads requiring maximum screw pull-out strength and compression resistance around fasteners.

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

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

5. What is the difference between PVDF, FEVE, and PE coatings for outdoor weatherability?

70% PVDF Fluorocarbon Coating-based PVDF (Polyvinylidene Fluoride) coating provides a 20+ year weatherability warranty against UV fading, chalking, and acid rain on exterior building facades. FEVE delivers high gloss retention for architectural landmarks, while PE (Polyethylene) coating is cost-effective for interior wall partitions and signage.

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

Yes. The pre-painted aluminum skins can be V-grooved at 90° or 135° on the reverse skin using standard CNC routers or hand tools, allowing manual edge folding into architectural cassettes without surface paint cracking. Edge sealing options include open edges, folded skin capping, or interlocking aluminum extrusion profiles.

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

Panels are packed with protective PE film on both aluminum skins, separated by inter-sheet foam layers, and secured on heavy-duty export wooden pallets or CKD (Completely Knocked Down) steel crates. This prevents surface scratching or edge impact damage during 20ft and 40ft container shipping.
