Barrier Cable Systems

VSL Barrier Cable SystemsBarrier cable systems are able to be used for all vehicle and pedestrian barrier needs and are compliant with all International Building Code standards. These systems are economically efficient – because of the high strength-to-weight ratio of the strands, the cables cost less to place than precast panels, traditional cast-in-place or concrete masonry barriers. Barrier cables are also a visually appealing alternative to traditional systems, such as concrete walls, which can create blind spots or similar hazards. Additionally, barrier cables can be used to replace traditional disposable safety cables required on jobsites – providing a solution that ultimately integrates into the barrier cable system.

Our systems feature galvanized ½”, 7-wire steel strands that can be packaged to include design, installation and fabrication of external anchoring devices, plates, cables, wedge sets, and stressing equipment.

STRUCTURAL TECHNOLOGIES offers several different levels of service for barrier cable systems. Involvement ranges from supplying systems, installation equipment and placement drawings to furnishing and installing barrier cables along with a full complement of steel components such as posts and angles. Our highly trained technicians are also ready to repair or replace strands or install safety cable systems during construction.
