Both the station entrances were produced
by Gothenburg-based Skandinaviska
Glassystem AB (SG) who specialize in the
design and fabrication of façades and cladding
systems. Diab have worked closely with SG on several previous occasions including
the development of an award-winning
sandwich composite cladding system.
Lightweight, high strength performance was
a key requirement of the sandwich composites.
In addition to being capable of supporting
the weight of any maintenance crews and
equipment, the sandwich components also
feature hidden run-off channels for rainwater.
The sandwich composite elements were
based on Divinycell P, Diab’s recyclable,
thermoplastic foam. Divinycell P offers excellent
FST (fire, smoke & toxicity) properties,
a wide processing envelope and very
good fatigue properties.
To achieve the complexity geometry and
the +/- 0.5 mm tolerances that were required,
the core was accurately machined to shape
using a three axis CNC milling machine.
Reinforcements were then applied directly
to the core thereby eliminating the need for
molds.
