Low Cost Cable Barrier- Best Choice for Open Scenic Area

A cable barrier, also known as cable guardrail, wire rope safety barrier, is the mainly type of flexible highway fences for keeping vehicles within the limits of correct way. Three or four high tensile wire ropes, mounted on the post, will absorb the maximum energy by flexing to cushion the unavoidable impact. Compare to other steel highway guardrail, this one is relatively cheaper and easy to install with a high effectiveness of redirection of errant vehicles when it is installed in a right way.

Advantages:

• Low cost
• High flexibility to install and repair
• Cable tension and post space can be adjusted.
• Prevent vehicles from running off the road effectively
• Absorb most sudden impact energy during collision
• Good looking for the usage in open scenic spots
• Anti-rust, anti-corrosion and anti-aging

Details about cables:

The barriers are manufactured with 3×7 high tensile steel cables. Meanwhile the wire ropes are galvanized for keeping the cable free of corrosion and rusting.

How to install cable barrier?

Cable number:

During installation, determine the number of cables according to different applications firstly. Three of four cables are commonly used. Generally, more cables, the higher ability to redirect the errant vehicles.

Space distance:

The barrier post often installed with spacing from 6.3 to 32.6 ft. The thing you must to chew on is that longer spacing normally means the higher deflection distance.

Tensioning:

Cables are fixed on the post and tightened to specific tension in accordance with the local temperature and environment. After tensioning, the reflection will be reduces and the ability to preventing vehicles from skidding off the road can be enhanced. Normally the tensions values range approximately from 2,000lb to 9,000lb.
