Precast Concrete Bridge Beams, Banagher Concrete
build. From 2000 to 2008 Banagher
developed 3 new beam types to add to
the range. The approval and acceptance
of these beams involved third party
checking and detailed reports. These
reports were then submitted to the NRA
(National Roads Authority) for analysis
and approval. Having gained approval
the Super U Beam was launched in 2000.
This beam which in effect is a deeper U
beam was developed to accommodate
large spans. These spans were beyond
the capacity of the existing U beam and
provided more options to designers at
longer spans.
In 2005 the ‘W’ beam was developed
as an alternative to the existing U, super
U beam and Y beam ranges. The W
beam system provides increased stability
during transportation and erection, greater
design economies and can accommodate
longer bridge spans. The range typically
spans from 17m to 45m. Investment in
8 axle twin steering modular bogie systems
ensures easy transportation to site with staff
highly trained in their operation.
In 2007 the MY beam was developed
to provide a more efficient prestressed
beam for the smaller span ranges. This
compliments the existing inverted T and
TY beam but, the 970mm soffit provides
a complete closed bridge soffit. This beam
is ideally suited over line rail and work may
continue without the risk of falling debris.
With these new products Banagher
Concrete can now supply customers
with more efficient, cost effective design
solutions, the highest quality product and
on time delivery.
