Post-Tension Cable

Barrier Cables: 
When and How 
to Use Them

Barrier cables, also known as guard cables or wire rope safety barriers, play a critical role in ensuring the safety of vehicles and pedestrians. These post-tensioned steel-stranded restraints can withstand significant force, making them ideal for parking garages and similar structures.

Applications of Barrier Cables:

  • High-strength fencing

  • Roadway barriers
  • Barrier replacement on existing structures
  • Safety code upgrades
  • Aesthetic and secure restoration projects
  • Retrofits to add steel cables

Types of Barrier Cables:

Galvanized Barrier Cables: The most common type, coated with zinc to prevent corrosion.
Plastic Coated Barrier Cables: Sheathed in plastic to prevent rust and allow color customization, like post-tensioning tendons.

Key Components of Barrier Cable Systems:

CABLES: Available in various thicknesses but typically are half an inch.
POSTS: Made of steel or concrete, calculated for optimal distance and type.
INTERMEDIATE SUPPORT: Control deflection and prevent sagging over continuous runs.
ANCHORAGES AND END FITTINGS: Essential for attaching cables to posts and ensuring system performance.
