01
Consistent relaxation performance
Bridge tendons hold force for the life of the structure, so the relaxation limit in the specification is not a formality.

Bridges
Strand and accessories for a long-span bridge
Global Overseas supplied prestressed steel strand and post-tensioning accessories for the bridge over Paranoa Lake in Brasilia, Brazil. Bridge work is the most demanding application for prestressing strand: tendons are long, the consequences of a relaxation or elongation problem are structural rather than cosmetic, and the inspection regime is strict.
For a bridge, the strand diameter, standard and relaxation class are fixed by the design, and the anchorage, duct and stressing equipment must be compatible with the strand as a system. Supplying strand and accessories together removes the interface risk that appears when components come from different sources.

Why it matters
What precast prestressing demands from the strand
02
Long tendon handling
Long tendons place demands on coil weight, strand straightness and the stressing sequence that the supplier has to support.
03
System compatibility
Strand, anchorage, wedge, duct and jack must be dimensioned as one system, not sourced independently.
04
Inspection before shipment
Bridge projects usually require third-party inspection and a defined document set before loading.
