1️⃣ Introduction: Choosing the Right Facade Material
In modern architecture, aluminum-based panels have become the preferred solution for building facades thanks to their light weight, durability, and design flexibility.
However, many buyers are confused about which type to choose — Aluminum Solid Panel, Aluminum Composite Panel (ACP), or Aluminum Honeycomb Panel.
Each material has its own structure, performance advantages, and application scope. Choosing the right one can significantly affect your project’s cost, durability, and overall appearance.

2️⃣ Aluminum Composite Panel (ACP): The Economical Choice
Structure:
Two thin aluminum sheets bonded to a polyethylene (PE) or fire-retardant core.
Advantages:
Lightweight and easy to install
Excellent surface flatness and rich color options
Low material and processing cost
Suitable for digital printing or decorative finishes
Limitations:
Fire resistance limited to B1 or B2 level (depends on core type)
Not suitable for high-rise or heavy-load curtain walls
May deform or age faster under strong UV exposure
Common Applications:
Shopfronts, signage, indoor walls
Low-rise exterior decoration
Advertising panels and display walls
✅ Best for: Cost-sensitive projects needing decorative but lightweight panels.

3️⃣ Aluminum Solid Panel: The Reliable Standard for Curtain Walls
Structure:
Made from a single aluminum plate (usually 2.5mm–4mm thick) with PVDF or powder coating on the surface.
Advantages:
Excellent weather resistance and durability
High structural strength and impact resistance
Can be bent or curved for architectural designs
Easy to replace and maintain
Limitations:
Heavier weight increases installation load
Flatness slightly lower than honeycomb panels
Higher material cost than ACP
Common Applications:
Exterior curtain walls of commercial and public buildings
Architectural facades with complex shapes or perforations
Ceiling and canopy panels
✅ Best for: Medium to large facade projects needing reliable performance and long lifespan.
---
4️⃣ Aluminum Honeycomb Panel: The Premium High-End Option
Structure:
Two aluminum sheets bonded to an aluminum honeycomb core through high-temperature composite technology.
Advantages:
Extremely high rigidity and flatness even for large panels
Lightweight (1/3 of solid aluminum panel at same stiffness)
Excellent sound and heat insulation
A2-grade fire resistance
High-end, seamless visual effect
Limitations:
Higher processing and installation cost
Requires professional curtain wall system
Complex edge-sealing and mounting process
Common Applications:
Airports, exhibition centers, office towers, transport hubs
High-end commercial and government buildings
✅ Best for: Projects demanding superior aesthetics, lightweight design, and durability.
