Edge filler
A filled perimeter for closing the exposed cellular core.
Technical Guide
Honeycomb Panel Edge Closure Designs
Edge filler, U-channel, Z-section, extruded-box and folded-edge approaches for protecting the core and preparing panel perimeters for fixing or finishing.
Why the perimeter matters
The edge is part of the panel system
An exposed honeycomb edge is not a finished connection. The perimeter detail is selected around appearance, water or debris exclusion, final sizing, stiffness, hardware loads and the way the panel connects to adjacent profiles.
Edge members and local inserts should be resolved before cutting and CNC work so drilling, tapping, hinges, latches and brackets land in a suitable reinforced zone. Exact extrusion, adhesive, weld and tolerance details are confirmed on drawings.
Selection inputs
- Panel thickness, core and face-sheet construction
- Visible, concealed or profile-covered perimeter
- Drilling, tapping, hinge, latch or bracket loads
- Water, debris, cleaning and corrosion exposure
- Final-size tolerance and CNC sequence
- Adhesive, mechanical fixing or welding method
Catalogue options
Eight edge and insert approaches
These diagrams establish the type of detail to discuss. Final extrusion geometry, material, adhesive, weld, tolerance and fixing method are confirmed on the project drawing.
U-channel
A channel cap that can cover both skins and the open core edge.
Z-section
An offset section for a stepped perimeter or interface detail.
Extruded box
A closed perimeter member where a more substantial edge is required.
Channel, legs in
A strength- and weight-conscious insert enclosed by the face sheets.
Solid edge enclosure
Aluminium or timber insert used where drilling or tapping is required.
Channel, legs out
A perimeter arrangement that allows the panel to be squared to final size.
Press-brake folded edge
A folded skin closure commonly considered for wall and ceiling panels.
Engineering the interface
Match the closure to the next operation
A neat edge cap and a hardware-bearing insert solve different problems. Mark every hinge, bracket, latch, handle, threaded fixing and exposed perimeter before panel cutting begins.
- Use a suitable reinforced zone where drilling or tapping is required.
- Coordinate the edge with the visible aluminium profile or joint.
- Confirm whether final squaring occurs before or after the edge member is fitted.
- Resolve water, debris and cleaning exposure for every open perimeter.
Drawing checklist
What to mark up
- Panel length, width and finished thickness
- Visible, concealed and profile-covered edges
- Cut-outs and final tolerance
- Hardware and local load positions
- Face finish and acceptable edge appearance
- Quantity, handing and packing sequence
