2-Layer / 4-Layer Honeycomb Panel vs Welded Aluminum Panel Comparison
2026/07/30
2-Layer / 4-Layer Honeycomb Panel vs Welded Aluminum Panel Comparison
1. 2-Layer Aluminum Honeycomb Panel Structure: 2 aluminum face sheets + 1 single-layer aluminum honeycomb core, bonded by high-temperature adhesive lamination (standard sandwich structure).
2. 4-Layer Aluminum Honeycomb Panel Structure: 4 aluminum face sheets + 2 double-layer stacked honeycomb cores. Multi-layer composite structure for upgraded strength and stability.
3. Welded Aluminum Panel Structure: Hollow aluminum profile frame welded as a whole. No honeycomb core, no adhesive bonding, pure welded integral structure.

4-Layer Honeycomb Panel
|
Welded Aluminum Panel
|
|---|---|---|---|
|
Structure
|
2 sheets + single honeycomb core, glue bonded
|
4 sheets + double honeycomb core, multi-layer composite
|
Welded hollow profile frame, zero glue, no core
|
|
Weight
|
Lightest, optimal lightweight performance
|
Medium, lighter than welded panel by 20-25%
|
Heaviest under the same thickness
|
|
Flatness & Rigidity
|
Excellent flatness, slight dent risk under strong impact
|
Superior rigidity, anti-deformation & anti-dent performance greatly improved
|
High rigidity, slight warping risk for large-size panels
|
|
Screw Holding Power
|
Average, easy loose after repeated disassembly
|
Excellent, firm screw grip, suitable for frequent disassembly
|
Outstanding, determined by profile wall thickness
|
|
Delamination Risk
|
Glue bonded, risk of bubbling/delamination under long-term high temperature
|
Low delamination risk due to multi-layer structure, still with glue layer
|
Zero glue, no delamination & bubbling risk
|
|
Sound Insulation
|
Good sound absorption
|
Best performance, double honeycomb structure reduces hollow resonance
|
Average, obvious metal hollow resonance sound
|
|
Surface Finishes
|
Full options: PET, PP, CPL, HPL, wood grain transfer, spraying
|
Same full finish options as 2-layer panel
|
Main for spraying & heat transfer, limited film wrapping options
|
|
Processing
|
Easy cutting & bending, suitable for large panels
|
High hardness, slightly difficult processing
|
Complicated welding & polishing process
|
