Angle Ring has always been at the forefront of new concepts,
and 2004 is no exception with its 3 dimensional bending
abilities.
Typically where a section is required for a helical or
spiral staircase spine or stringer the bend would be achieved
through fabrication of thin flat plate stringers, which
would then be welded to form the sections required.
Now however, Angle Ring is able to bend structural sections
into spirals opening up new scope for staircase design
and construction.
Paul Middleton from Angle Ring stated The new capacity
for 3 dimensional bending opens new possibilities for
architects and engineers
Examples are the Next Generation leisure club (shown)
at Brierley Hill, West Midlands, which consists of 230x90
PFC sections curved to form the inner and outer stringers.
Using structural sections allows much longer spans, without
the need for vertical supports, opening the normally redundant
space below.
This allows stunning designs to become a reality without
the cost normally associated with helical or spiral stairs.
Tubes, Channels, Beams, RHS and Plate can all be spiralled
in sizes to suit your application.
Sizes currently available as spirals:-
Beam up to 406x140 UB
Channel up to 430x100 PFC
Tube up to 914mm diameter
RHS up to 300x100 RHS or 430x200 fabricated RHS
Plate up to 200mm thick.
