Technical Details

ALUCORE® is an aluminium sandwich-type panel with high rigidity and extremely low weight. In contrast to conventional honeycomb composite materials, the system components, i.e the aluminium core and the coil-coated aluminium cover sheets are bonded in a continuous process.

The advantages are product quality and surface evenness. The material does not become brittle hard but shows tough and resilient properties and an excellent peel strength. Following in the footsteps of the ALUCOBOND® trademark, ALUCORE® is the ideal material for a host of applications in transport, architecture or industrial production.

The honeycomb core consists of aluminium foils made of the alloy AIMn (EN AW 3003) cell size b: approx 6.3-12.7 mm. The cover sheets of the panels consist of corrosion-resistant Peraluman alloys and may be used in a decorative or functional manner, depending on the purpose of application.


Wind Load and Permissible Panel Sizes

The diagrams below indicate the available ranges of panel thickness and permissible panel lengths at a given parnel width (1250 or 1500mm), depending on the loads applied.

The tables apply to panels supported on four sizes (corners fixed). Dimensional values for other systems are available on request.
