Carbon Steel Systems |
| The carbon steel range of components
consists of fifteen available diameters
ranging from 6 mm to 60 mm. Tension rods
and anchor discs can be provided in black,
zinc plated, or hot dip galvanised finishes.
The maximum available length of tension
rod varies according to the finish and
diameter selected. System diameters and
load capacities are detailed on page 6. |
| Where large spans are necessary, couplers
and anchor discs can be used to extend the
system to the length required. Fork
connectors, couplers, and locking nuts are
only available in zinc plated finish. |
Stainless Steel Systems |
| Stainless steel systems are typically used in
situations where a high resistance to
corrosion is necessary, or where a polished
finish is preferred. Stainless steel tension
rods are available up to six metres long in
nine diameters ranging from 6 mm to
30 mm. System diameters and load
capacities are detailed on page 6. As with
the carbon steel system, couplers, and
anchor discs may be used to extend the
system when long spans are required. All
components of the stainless steel system are
available in bright drawn, electro-polished,
or hand polished finishes. |
Tension Rods |
| Tension rods are supplied with one left hand
and one right hand thread to compliment
the threaded adjustment facility in the fork
connectors. Flats on the tension rod enable
a spanner to be used to turn the rod on its
threads. Depending on the direction that
the rod is turned the length of the system is
either increased or reduced within the limits
of its adjustment. |
Couplers |
| Couplers are used to join tension rods in
applications requiring long spans. They also
provide an additional facility for adjusting
the system for length. Each coupler is
provided with two locking nuts. Sizes M12
and above can be supplied with a welded
lug to provide a hanger connection if
required. Hangers can be used in long span
applications to limit system deflection. |
Anchor Disks |
| Anchor discs are another method for
extending the span of the system, or they
can be used to provide a central connection
point for structures requiring cross bracing.
A maximum of eight bars may be
connected to each anchor disc. |
Fork Connectors |
| Fork connectors provide an adjustable
connection between the tension rod and
connection plates on the structure or anchor
discs. Each fork connector is provided with a
pin and two circlips to provide a safe and
aesthetically pleasing attachment method
for the system. Fork ends are sealed from
moisture penetration with a colour-coded
plug. A yellow plug denotes right-hand
thread, and a blue plug denotes a left-hand
thread. |
Locking Nuts |
| Locking nuts secure the tension rod after
adjustment, and are designed to provide a
visually attractive transition between the rod
and the fork connector. |
| Locking nuts for systems M6 to M12 are
tightened with soft touch pliers. Sizes M16
and above are tightened using a peg
spanner provided with the system. A
combination of flat and round seals can be
provided to special order for locking nuts
M16 and above, if it is desired to seal to the
threads from the accumulation of moisture
or dirt. To provide a visual safety check, the
locking nut hides an indicator mark on the
tension rod only when the system is within
its allowable range of adjustment. |
