Great Circle Rigging Ltd Threaded Bar Systems

Stainless steel bars can be used in a variety of applications where there is a requirement for both structural and/or an architectural feature e.g. a planar glazing system. The stunning effect of stainless steel bars can enhance glazed structures, roof trusses and cross-bracing. They can also be used in areas where more rigidity might be appropriate such as uplift on entrance canopies etc. The quality polished tendons are cost effective and durable because they are ready for installation and require no painting.
Bar System GC446. Threaded bar fixed length system
(for lengths less than 3.2m)
Threaded bar fixed length system
Simple fixed length system. Use is limited to lengths of under 3.2m. For longer lengths full strength couplers can be supplied.

Bar System GC465. L/H & R/H Standard threaded bar system
L/H & R/H Standard threaded bar system
Simple adjustable tension rod system. The bar is threaded with opposite threads at either end. The threaded ends are screwed into forks with mating threads. The system is tensioned by rotating the bar using the machined spanner flats provided.
Bar System GC465/4. Standard threaded bar with couplers
(for lengths greater than 3.2m)
Standard threaded bar with couplers
Adjustable tension bar system for greater than 3.2m. stainless steel couplers provide full strength connections allowing tie bar lengths greater than 3.2m to be assembled. Generally one coupler is provided every 3.2m of bar.

The new Adjustable Tube Strut is designed to take the tension loads of canopies in the accepted and conventional way.
In addition to the tension involved, the stainless steel Adjustable Canopy Tube Strut will counteract most of the high wind uplift that can be experienced in many area where exposed canopies can be at risk.
All Tube Struts are considered to be individual according to architects requirements and are therefore custom made to suit a particular project.
