A spiral strand is a composite of multiple layers of helically twisted steel wires. Layers are spun in opposite directions providing constructional and torque stability. The use of high strength steel wires makes it a good candidate as tension member in static applications. Our proprietary Bridon-Bekaert blocking compound fills the cable on the inside, reducing the impact of steel-steel contact, and adding an additional barrier against corrosion.
Good fatigue resistance
The wire is coated using a patented gas wiping process, which heavily galvanises the wire in a smooth, even coating of zinc, up to 400gm/m².
Factory assembly & pre-stress shorten your installation time
Bridon-Bekaert manufactured the cable assemblies and provided installation and tensioning equipment and assistance for the Newport City Bridge in Wales, UK.
