A composite footbridge has replaced a
50-year-old timber footbridge in Sedlescombe, Kent. It is a fraction of
the weight of its predecessor.
The production of the footbridge was a
result of a partnership between Norco Composites and Concrete Repairs.
Driving factors in the development were low maintenance, aesthetics and
light weight for ease of installation. The bridge solution also had to
be produced at a target cost which would not deter decision makers from
selecting composites for their long term benefits.
To meet structural requirements, the
bridge used infused unidirectional fibers in the bridge deck and beam
cappings combined with overlaid multi-axial fabrics at +/-45 along with a
vinylester resin system. The final bridge deck weighed 600 kg (1,322
lb) with the powdercoated and galvanized handrails weighing an
additional 400 kg (882 lb). This is more than 3 tons lighter than the
wooden bridge it replaced. The bridge was installed within one hour in
Seddlescombe with minimal disruption.
