Barrier Cable

Barrier Cable Systems by Tendon Systems is an engineered vehicular impact and pedestrian control solution that reduces the construction and maintenance cost of parking structures.

Tendon Systems Cable Barrier eliminates the need for costly structural members by utilizing durable, high-strength tensioned barrier strands.  Tensioned barrier cable resists impacts and springs back to its original position after impact thus avoiding the permanent deformation that other systems would incur.

Tendon Systems can design challenging and difficult projects while meeting our Client’s expectations, budget and schedule. Having in-house Registered P.E.’s enables Tendons Systems to offer innovative, cost effective engineered solutions for specialized applications.

Tendon Systems field service technicians will provide on-site assistance for system installation, stressing, and sequencing. Our field crews are PTI-Level 2 certified and we use only certified welders.

During the past 30 years our team has completed over 1,000 projects centered around barrier cable systems and services for vehicular and pedestrian restraint and safety protection.  Seasoned management leadership combined with a dedicated staff of experienced professionals provides our Clients with a reliable project partner who adds value from conception to completion.

Products Overview

Tendon Systems provides the following products and services:

• Barrier Cable

• Specialized End Terminations & Support Posts

• Fencing

• Galvanized Steel / Plastic Coated Products

• Retrofits & Code Upgrades

• Additional Services

• Cable Types and Sizes

• Anchorage and End Fittings

Tendon Systems offers Barrier Cable Systems in several coatings and corrosion protection levels depending on use and environment.

Our barrier cable is primarily produced with half inch diameter strand. Other sizes are available upon request.

There are three types of barrier cable systems:

• Galvanized

• Epoxy Coated

• Plastic Coated

The most widely specified coating is Class A-ASTM A475 galvanization. Enhanced coatings include a zinc aluminium alloy ASTM B750 Galfan which offers 3 to 1 corrosion performance enhancement.

Epoxy Coated is used primarily for aesthetic purposes. It is more expensive than galvanized barrier cable.

Additional protection aesthetics can be provided with the addition of a 60 mil extruded sheathing of high density polyethylene which is hot melt extruded over wax coated cable. The HDPE sheathing can be manufactured in a wide variety of colors. Special ultraviolet, anti-oxidizing inhibitors are added during the process to ensure durability and weather resistance.

Barrier Cable Retrofits, Code Upgrades, Restoration & Replacement

Tendon Systems Barrier Cable Division can retrofit the existing barrier cable system in your parking structure to meet updated building code requirements or to avoid a life safety issue.  Tendon Systems will even come in and replace or restore other company’s products that prematurely deteriorated.

Tendon Systems Structural Engineers can design new terminations and support posts to meet the newer and more stringent Code requirements.   Tendon Systems team of Engineers, Project Managers and PTI Certified field crews are your turn-key source for barrier cable replacement.

Traffic Coatings, Sealants and Specialty Services

Tendon Systems Superintendents and craft workers are also experienced in traffic coatings, sealants and other specialty services.  This work can be simultaneously completed during barrier cable installation which provides an acceleration of the total construction schedule.

As a member of the International Concrete Repair Institute (ICRI), Tendon Systems stays abreast of the latest industry trends and innovations with materials and methods to extend project durability.

Tendon Systems offers a wide variety of standard end anchorages and specialized end fittings.  Each anchorage is designed to handle the full guaranteed ultimate force of the cable although the actual design load is much lower than this.

Standard end anchorages are utilized where access for stressing is available on the back side of the terminating support.  These anchorages may be either recessed into a concrete column or wall or surface mounted.

Specialized end anchorage components are available where access is not available on the back side of the cable termination.   The end anchorage fittings and components may be protected through hot dip galvanizing (ASTM A153) or zinc plating conforming to ASTM B633.

All end anchorages and specialized end fittings allow for back stressing, an installation requirement of the Post-Tensioning Institute (PTI).
