Product Overview
The CHAOEN All-Aluminum Tongue-and-Groove Wall Panel is an interlocking wall cladding system engineered for rapid, seamless installation in interior and exterior applications. Each panel consists of two aluminum skin sheets (0.5–1.0 mm, 3003/5052 alloy) bonded to an aluminum honeycomb core, with a precision-machined tongue on one longitudinal edge and groove on the other. The tongue-and-groove joint ensures perfect alignment, eliminates visible fasteners, and accommodates minor thermal expansion while maintaining a flat, continuous surface. The panel is 100% metal (no wood, plastic, or adhesive fillers), making it fully waterproof, fireproof, and formaldehyde-free. A two-person installation team can complete 80–120 m² per day - 3–5× faster than ceramic tiling. Ideal for bathroom walls, kitchen backsplashes, hotel interiors, hospital cladding, and high-humidity commercial spaces.

• Brushed metal: linear grain texture for industrial-chic and loft-style interiors
Custom digital printing with brand patterns, artwork, or corporate graphics is also available.
Q: 7. Is the panel fire-resistant?
A: Yes. The all-aluminum honeycomb tongue-and-groove wall panel is 100% metal construction and rated Class A non-combustible under GB 8624 and Class A1 under EN 13501-1. It will not ignite, contribute to flame spread, or emit toxic smoke under fire conditions. This makes it suitable for all building types including high-rise residential, hotels, hospitals, schools, and public assembly spaces where stringent fire codes apply. Independent fire test reports (GB 8624, EN 13501-1, ASTM E84) are available upon request.
Q: 8. What is the typical production lead time?
A: • Standard stock items (white/grey powder coat, 600×2400mm): 5–10 working days
• Standard size, custom color/finish: 10–15 working days
• Custom wood-grain or special finishes: 15–20 working days
• Non-standard dimensions requiring custom tooling: 20–25 working days
• Large-volume project orders: schedule confirmed upon PO review with phased delivery available
Sample panels (300×300mm with tongue-and-groove joint demo) can be dispatched in 3–5 working days for finish approval. We recommend ordering samples before full production to confirm color, texture, and joint fit.
Q: 9. How are tongue-and-groove panels packaged and shipped?
A: Packaging: Each panel is protected with 50μm PE film on both faces. Panels are stacked face-to-face with PE foam interleaving (3mm) to protect the tongue-and-groove profiles. The stack is enclosed with 5mm MDF cover boards top and bottom, then strapped with PET bands. All four corners and the tongue/groove edges are reinforced with heavy-duty cardboard angle protectors to prevent profile damage.
Export packaging: ISPM 15 fumigated plywood crates with internal foam cushioning. Optional vacuum-sealed packaging for LCL sea freight.
Shipping:
• Domestic: door-to-door trucking; panels are shipped flat (never on edge) to preserve joint precision
• International: FCL 20GP/40HQ sea freight; CIF/FOB standard; DDP available for select markets
• Sample shipping: DHL/FedEx/UPS for small-quantity evaluation samples
Custom barcodes, QR codes, and project labels for site logistics tracking are available.
Q: 10. How are tongue-and-groove wall panels installed?
A: Installation is designed for speed and simplicity:
Substrate preparation:
• Panels can be installed over leveled concrete, masonry, steel stud framing, or existing tiled walls (after degreasing)
• Substrate must be dry, clean, and flat within ±2mm over 2m
• A vapor barrier is recommended in continuously wet areas as a secondary defense layer
Installation steps:
1. Starting profile: fix an aluminum or PVC starter channel at the floor/bottom edge to receive the first panel groove
2. First panel: apply structural adhesive (MS polymer or polyurethane) in vertical beads on the substrate; press panel into starter channel
3. Sequential panels: apply adhesive on substrate; insert the tongue of the new panel into the groove of the installed panel at a 15–20° angle; press flat against the wall
4. Leveling: use a rubber mallet to gently tap panels into perfect alignment; spacer wedges at top/bottom ensure consistent expansion gap (2–3mm)
5. Finishing: top/end profiles cap the final exposed edges; silicone sealant at internal corners and perimeter joints
Key tips:
• Install from left to right (groove facing incoming panel) or bottom to top
• Maintain 2–3mm expansion gap at all perimeters - fill with color-matched silicone
• Use low-expansion PU foam adhesive for uneven substrates (>3mm variation)
• Two installers can complete 80–120 m² per day
