There are many advantages in designing with FABSEC® long
span cellular composite beams. The section design may be
optimised in FBEAM® to produce the most efficient solution first
time, with the beam weight usually substantially less than plain
steel beams or castellated alternatives.
The unrivalled cell geometry and position permitted in FABSEC®
beams includes circular, rectangular and elongated openings in both
normal and fire-engineered conditions. Due to low cost manufacture,
the low weight is complemented by an economical rate per tonne,
resulting in a highly competitive lump sum price.
The long span grid arrangement reduces the number of columns to
allow architectural freedom and reduces the piece count for the
whole fabrication and erection process. In addition, the passage of
the services through the web of the beam reduces the floor sandwich
depth and consequentially the overall building height.
FABSEC® beams are used for primary and secondary floor beams and
rafters, can be composite or non-composite with typical floor spans
of 8-24 metres and roof spans of up to 60 metres.
