CABLE SYSTEMS FOR BRIDGES
Many bridges around the world are held up today with Teufelberger-Redaelli structural cable systems. The 200 years of experience that Teufelberger-Redaelli can call upon ensures the safest, highest quality products in the world. Our complete and expansive range of know-how used to develop and design the cable systems, along with the related accessories for installation and tensioning means all bespoke and technical specifications for each project are catered for.
The cable system, prefabricated in the factory using the highest quality cable, sockets, socketing and finishing, will fulfil the design and installation needs of your project. Our range of high-performance steel cables can be either supplied using Full Locked Coil (FLC) ropes or Open Spiral Strands (OSS). Both solutions are available with poured spelter cone type sockets (resin or zinc filled) or with pressed swaged sockets depending on the cable diameter and the project requirements and specifications.
High Density Polyethylene (HDPE) can be applied to structural cables for improving corrosion protection, increasing visibility and for architectural, aesthetic reasons. This option has an impact on the sockets choice which are specifically designed and manufactured to accommodate the additional HDPE layer within the socket neck. Teufelberger-Redaelli’s HDPE sheathed cables are designed and produced to extend and prolong the cable systems lifespan, offering a good resistance to oils, water, chemicals and abrasions.
Generally stainless-steel cables are selected in applications where the cable system is highly visible or as an architectural feature for example transparent facades, glass curtain wall facades, exhibitions and convention centre halls, pavilions, footbridges and cable net roofs. Stainless steel cables are available as Full Locked Coil (type FLX) or Open Spiral Strand (type OSX).
Teufelberger-Redaelli has a specialist team of site technicians supported by construction engineering expertise and an extensive fleet of industry leading installation and tensioning equipment.
Whether in a new build environment or in a renovation and replacement of an existing structure our dedicated site engineering team are available to discuss the challenges of your project.

There are considerable advantages to utilizing Teufelberger Redaelli’s team of higly skilled and experienced site installation, inspection and maintenance team to ensure your cable systems are accurately, carefully and quickly installed and tensioning to precise measurements. Specialist cable handling equipment is used to ensure the cables are installed without damage and to specification. The extensive & optimized range of Teufelberger Redaelli sockets, clamps and spacers result in reduced anchorage details, components and required space which in turn leads to economical cost saving and optimal aesthetics when compared with larger alternative cable systems such as parallel tendons which require large mechanical individual tendon anchor grips, grouting and ducts. Teufelberger Redaelli cables also have greater flexibility within the monolithic cables.
