The attractive spaceframe construction of the roof allows for large spans to be free of sloping rooflines.

Tri-dimensional alu frame

In order to obtain fast erection and dismantling time and fulfil the demanding wishes of several clients, De Boer developed the highly flexible and easy to install Delta by De Boer system.

The new system offers unparalleled opportunities for temporary space utilisation and ventilation.

Frame
- Adjusted tri-dimensional aluminium frame realised with 5mx5m basic modules for fast construction and dismantling possibilities. The repetition of about ten basic elements is sufficient to build any types of structures.
- Aluminium bi-articulated poles placed every 5 meters on the periphery of the structure. Up to 40-meter span.

Cover and outside walls
- Solid security white DE BOER side panels, constant internal height of 6,4 or approximately 9,0 meters.
- Aluminium louvered ventilation panels on two levels.
- Suspended cassette floor by DE BOER.
- Mezzanine floor sections possible based on 5x5m grid.
- Installation options for pushbar/glass doors, PVC doors, emergency doors, smoked glass windows, ventilation panels.
- PVC white or opaque roof covers with "Chinese Hat", including ventilation.

Erection and lifting operation
- Structure and covering are safely assembled on the ground; all necessary lighting and other technical facilities can be easily installed.
- The lifting operation is performed with cranes or jacks, depending on the structure to be erected.
- Erection time depends on size and lay-out of structure, in general the construction time takes between three and ten days.
