How it is built
Stiffness where it counts, weight where it doesn't
A honeycomb sandwich panel separates two thin, strong skins with a lightweight core. Moving the skins apart raises the panel's bending stiffness sharply while adding almost no mass — which is why the same construction shows up in aircraft flooring, rail interiors, and architectural facades.
- Face skin
- Aluminum, stainless or FRP — bonded both sides
- Structural adhesive
- Film adhesive, cured under heat and pressure
- Honeycomb core
- 3.2–25 mm hexagonal cell, expanded to thickness

Anatomy of a core
The dimensions you'll quote on
- Cell size
- Width across one hexagonal cell — smaller cells give a denser, stiffer core.
- Cell pitch
- Centre-to-centre spacing between adjacent cells; sets how many cells pack into an area.
- Node
- The bonded wall where two foils join. Node lines run the length of the sheet and define the ribbon direction.
- Cell height
- The core thickness — the gap between the two skins. More height means far more bending stiffness for almost no weight.
- Length & width
- The in-plane sheet dimensions, cut to your panel size.
Marine fire rating
What decides the class
- Face sheet melting point
- Steel skins hold at far higher temperatures than aluminium.
- Bonding adhesive resistance
- A resilient adhesive bond keeps the skins and core working together through heat, moisture and chemical exposure.
- Honeycomb core density
- A denser core carries load longer as temperature rises.
- Total panel thickness
- More thickness buys more time before heat reaches the far side.

Pick the core that fits the load case
Every structural core we stock, measured on the three numbers that decide a specification. Each chart has its own scale — density and strength are not comparable on a shared axis.
