Sandwich Wall Panel — Aluminum​ Corrugated & 3D Cored

The Aluminum Corrugated Core Sandwich Panel is a high-performance all-aluminum façade material developed by Chalco, featuring a "surface panel + 3D aluminum core + back panel” integrated metal structure. Compared with traditional honeycomb panels, it offers higher strength, better processing flexibility, and improved fire and weather performance.

Key Features:

• 3D aluminum core structure: enhanced strength and bending stability
• All-aluminum, no plastic core: A2 fire rating, safe and eco-friendly
• Flexible processing: ideal for bending, shaping, and modular systems
• Cost-efficient: higher structural utilization and better system compatibility
• Multiple finishes: anodized, PVDF, polyester, wood grain, stone grain, brushed metal, etc.

Widely used in façade cladding, exterior renovation, medical clean spaces, and modular wall systems, it is a high-strength sandwich wall panel solution for modern architecture.

3D aluminum core sandwich panel vs. aluminum honeycomb panel: Why is it the better choice?

• Structural differences: Three-dimensional aluminum core panels use a three-dimensional aluminum core + adhesive layer composite, while honeycomb panels use a hexagonal honeycomb core + glue hot-pressed structure.
• Cost advantages: Lower aluminum consumption, simpler process, no reliance on honeycomb stretching and large amounts of adhesives, overall cost can be reduced by about 10-30%.
• Fireproof and environmentally friendly: All aluminum core material, no plastic foam, can achieve A2 fire rating and is recyclable;
• Processing advantages: stronger resistance to collapse, can be bent, milled, and made into arcs, suitable for irregular curtain walls and prefabricated wall panels.

Chalco Aluminum 3D-cored Plate Structure Composition and Technical Advantages

Lightweight, high-strength, thermally insulated, prefabricated applications, material upgrades, and breakthroughs in structural technology

Three-dimensional aluminum core sandwich panels are based on an all-aluminum structure and a three-dimensional core design, achieving a perfect balance of strength, weight, and processing performance through precision composite technology. They not only inherit the robustness and metallic feel of traditional facade sandwich panel systems, but also meet the demands of modern architecture for lightweighting, energy conservation, environmental protection, and rapid installation.

In short, 

the core competitiveness of 3D aluminum core sandwich wall panels is not just "lightweight, strong, and fireproof", but its systematic innovation in structural design and manufacturing process, which enables metal curtain walls and prefabricated interior decoration to achieve true "high-performance integration".

Whether it's high-end curtain wall projects, medical cleanrooms, or prefabricated modular engineering, we can provide customized structural designs and rapid installation solutions (sandwich building panels) to meet your application needs.

Chalco 3D Aluminum Core Sandwich Wall Panel Project Overall Solution – Production and Processing System

Chalco, a professional aluminum alloy materials manufacturer, provides systematic materials and processing solutions for curtain wall, interior decoration, and prefabricated building projects worldwide. We possess a complete manufacturing system from raw material casting, sheet metal composite, precision machining to finished product delivery, ensuring that products are ready for installation before leaving the factory and providing high-performance integrated support for building projects.

Raw Material & Quality Control

• It adopts a high-purity aluminum ingot melting and casting system and strictly implements international standards such as GB/T 3880 and ASTM B209;
• Production range: Thickness 8–35 mm, width ≤ 2000 mm, length ≤ 8000 mm;
• The core board and the panel are bonded together using an environmentally friendly, high-strength adhesive system and cured at a constant temperature to ensure flatness and strength.
• The product has a fire rating of up to A2, excellent weather resistance and corrosion resistance, and is suitable for long-term indoor and outdoor use.
• Each batch of products undergoes flatness, bonding strength, fire resistance, and appearance testing, and is accompanied by an inspection report and a traceable batch number.
• Surface finishes include anodizing, fluorocarbon coating, polyester coating, wood grain transfer, stone grain, brushed metal, and mirror finish.

Pre-installation fabrication capabilities

All aluminum 3D sandwich panels undergo various precision processing and prefabrication treatments before leaving the factory, ensuring that customers can directly proceed to the assembly or installation stage after delivery.

• Bending: edge binding, corner forming, and folding to maintain structural stability and precise shape;
• Curving: Three-roll mills can achieve large-radius or hyperboloid shapes with a smooth, crease-free surface;
• Slotting: Slotting on the back facilitates bending and forming, allows for precise angle control, and produces smooth lines;
• Drilling/Riveting: Pre-drilled screw holes and riveting positions improve installation efficiency;
• Saw Cutting: CNC cutting offers high precision, ensuring clean edges and minimal dimensional tolerances;

All processes are completed in the factory, ensuring ready-to-install assembly, effectively shortening on-site construction time, reducing errors, and saving overall costs. Welcome to contact Chalco for customized fabrication and integrated project solutions.
