Fabricating a porcelain honeycomb panel means coordinating the ceramic face, the reinforced backing, the exposed edges and the rear fixing positions. A cutout that fits the elevation can still conflict with a rear bracket, and a straight cut can leave the honeycomb core visible at a finished edge.
For Funtek’s construction, the ceramic face is on one side only. Beneath it are the bond, the PU fiberglass skin, the aluminum honeycomb core and the rear PU fiberglass skin. Define the finished shape and its edge treatment before cutting so the supplied panel is ready for its actual position in the wall, ceiling or furniture component.
Define the Finished Panel Before Cutting
Why the Reinforced Backing Helps Fabrication
The product literature identifies processing difficulty as one consequence of making ceramic very thin. A loose thin face is vulnerable when it bends during transfers and positioning. Bonding it to the PU fiberglass-faced honeycomb produces a deeper, reinforced assembly: the core distributes forces and keeps the skins separated, while the bonds keep the layers working together.
That support makes the thin ceramic more manageable through the fabrication sequence and transport to its installation position. Factory bonding, the finished cut outline, edge closure and rear fitting locations can be coordinated as one supplied panel. The strength and impact results explain the reinforcement; the supported cutting and opening details below apply it to the actual finished part.
Start from the finished visible size, the face direction and a consistent measuring reference. A drawing needs to distinguish the overall composite outline from the exposed ceramic area, the joint beside the next panel and any edge trim. If all four are represented by a single rectangle, the fabricator has to guess which line controls the saw and which controls the installed appearance.
Choose the front-view reference and keep it through the drawing set. Show an orientation arrow for a directional vein, identify the visible face and label a mirrored or handed part distinctly. The same dimensions can describe two opposite-handed panels; the face and back views resolve which one is intended.
The fabrication sequence depends on the part. A face can be prepared before bonding, or selected features can be processed after the composite is formed. The useful question is which route gives a supported face, the required edge and access for the rear components. An opening that will be difficult to support after assembly belongs in the fabrication review, rather than being left as an instruction to cut on site.
Record the face and backing thicknesses separately. The panel thickness and dimensions guide explains why “12 mm panel” is incomplete when the drawings need to locate a clip, a return or a trim against the rear surface.

Plan Openings Around the Complete Composite Build-Up
An electrical opening passes through more than a hard ceramic sheet. Cutting also interrupts the front backing skin, the cells and the rear skin. The remaining piece needs support while the opening is formed and while the finished panel is moved. Keep both the panel and the removable offcut supported so the last part of a cut is not forced to carry a hanging piece.
Draw the opening shape, its dimensions and its location from the agreed datum. Include the equipment’s insertion clearance and the area hidden by its cover plate or trim. A nominal equipment size is not necessarily the cut size: the body, flange and access needed to tighten the fixing can occupy different spaces.
Inside corners need a fabricable geometry and continuous support around the remaining material. A line drawing with a mathematically sharp internal corner does not describe how a brittle face will be processed. Agree the internal shape with the selected face material and fabrication process; do not replace it with a universal radius copied from a different slab product.
Example drawing note: “Front-view datum at lower-left finished corner. Socket opening centered at the dimensions shown; cut size and internal corner geometry to match the accepted equipment template. Provide the agreed edge closure and maintain the rear fitting clearance shown on the back view.”
This note connects the visible opening to the template and back view. It is more useful than adding “cut to suit,” which leaves the fabricator without a defined finished condition.
Choose an Edge Closure for the Exposed Core
A raw cut shows the honeycomb cells between the skins. That can be useful on an inspection sample, but it is a separate condition from a finished exposed edge in a building. The selected edge treatment determines what is visible, what protects the thin face edge and how the perimeter meets adjacent work.

| Condition | Panel detail to resolve | Effect on the drawing |
|---|---|---|
| Exposed cut edge |
 Identify where the raw composite edge will be visible and which layers need protection or concealment.
|
Mark every exposed perimeter and opening so it receives an intentional finish instead of an unspecified saw-cut boundary. |
| Closure profile |
 Consider a suitable closure or profile that conceals and protects the core while preserving the required face appearance.
|
Show profile size, its relationship to the face and back, attachment and any space it occupies beside rear fittings. |
| Return or corner |
 Resolve how separate ceramic-faced elements meet and how their backing and supports are connected.
|
Show finished external size, joint or trim, return depth and the independent support or approved assembled detail. |
A profile attached around the edge can affect the panel’s overall size. A return changes the visible depth and may occupy space otherwise used by a rear clip. A closed edge that looks flush from the front still needs an agreed rear termination so it does not prevent the panel from seating on its support.
The composite construction guide explains the layers at this cut edge. Sealing the ceramic surface, closing a core and forming the facade weather line are three different functions. A decorative edge strip should not be described as a complete external drainage or weatherproofing detail.
Detail Outside Corners, Inside Corners and Returns
At an external corner, decide which face continues visually and how the edge of the adjacent face is concealed. Two flat panels with a trim can be simpler to separate and replace. A prefabricated returned element can reduce the number of site-assembled parts, but its geometry, support and packing have to accommodate the return as a complete piece.
An internal corner has a different assembly sequence. If one panel must slide into a mating fitting, leave enough room for that movement before the adjacent return closes the space. The corner can look correct on a plan while being impossible to engage in the intended installation order.
For a window return, show the depth from the facade face to the frame and the space required for the joint and sill. In a facade renovation, this depth changes when the new outer face moves forward. Keep the frame interface and water route visible in the section, rather than completing the corner only as a material junction.
Do not specify a ceramic-faced panel by copying a routed-and-folded aluminum sheet detail. The ceramic face and reinforced backing need a fabrication route that preserves their actual geometry.
Coldspring publishes separate edge conditions and corner details for its StoneLite system. They illustrate why perimeter and corner conditions deserve individual drawings. Develop each detail around the selected panel construction, connection and finished geometry.
Keep Cutouts Clear of Inserts and Rear Fixings
Place the front-view machining outline over the rear fixing layout using the same origin. This immediately reveals a socket opening that cuts through a bracket zone, a trim that covers a rivet line or an equipment body that will occupy the cavity needed to engage a mating clip.
Show the whole component envelope. A bolt center locates one point, while a bracket has width, a nut needs tool access and a mating fitting needs an engagement direction. Those spaces are especially easy to lose near corners and narrow strips beside an opening.
When an opening conflicts with a fixing, review the part before cutting. The available options can include changing the panel division, relocating equipment, revising the fitting arrangement or revising the opening’s relation to the finished face. The chosen correction belongs on both views and on the revised panel schedule so a superseded drawing does not return to production.
The inserts and panel fixings article explains the connections shown in the product material. Cabinet doors add a different interface: a hinge or handle needs a planned reinforced area, as discussed in the honeycomb-backed cabinet door construction guide. A convenient open cell is not a substitute for an intended hardware connection.
Approve a Representative Fabrication Sample
Select a sample that includes the difficult features rather than only a flat decorative square. For a facade package, this might combine an external corner, an exposed lower edge and a nearby opening. For an interior panel, an equipment cutout and a mating clip can be more useful than an unrelated facade corner.
Compare the sample with the drawing from the front and back. Examine the ceramic edge for chips and the composite perimeter for gaps or local crushing. Check that the closure sits as drawn, the rear component is accessible and the mating part can be installed without pulling the ceramic edge. Record the actual inspection locations and the agreed appearance reference.
Then try the assembly sequence on the sample support. Engage the fitting, bring the adjacent piece into place and remove the panel by the intended route. This exposes a clearance problem before it is repeated across a full elevation. The accepted sample should carry the drawing revision and component identities so later production can be compared with the same detail.
Approve the visible edge and the rear assembly together. A good-looking face sample alone cannot show whether the fitting can engage, be adjusted or be reached after installation.
Release a Complete Fabrication Drawing
The release package should let the fabricator identify the finished part without resolving design choices on the machine table. Include these connected items:
- Identity and orientation: unique panel ID, location, front-view arrow, visible face and drawing revision.
- Geometry: finished outline, face dimensions, backing thickness, openings and all dimensions from the same datum.
- Perimeter: each exposed edge, trim or closure, corner and return, including its finished depth.
- Rear assembly: component type, locations, reinforced regions and the space needed to engage or adjust the fitting.
- Approval and inspection: equipment templates, accepted sample reference and features to check before packing.
For a simple wall panel with one socket, the front view locates the opening and face direction; the section shows the closure through the complete composite; the rear view locates the clip and confirms equipment clearance. Together they describe one part. A new revision to the socket location requires checking the other two views rather than changing only a dimension beside the opening.
