A cable barrier, also known as cable guardrail, wire rope safety barrier, is a flexible guard railing system toprovide good safe guard in open areas. This barrier system composed withchiefly hot dipped galvanized steel wire strands, steel posts and terminalsoffering excellent rust resisting and corrosion resisting property.
Thistype of wire rope safety barrier is a kind of highway fence keeping vehicleswithin the limits of correct way. The wire cable barrier is made with three,four, five or six high tensile steel wire ropes, firmly mounted on the steelpost at certain spacing to form a flexible guard barrier. The more number ofthe wire cables, the much strength the barrier offers.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:
Details about cables:
Thebarriers are manufactured with 3×7 high tensile steel cables, the most commonlyused are 18mm and 19mm steel wire ropes. A 3×7 steel wire rope has threestrands, each strand is made up of 7 identical wires wound around a center.Meanwhile the wire ropes are galvanized for keeping the cable free of corrosionand 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.
Application:
1.usedfor the sides of highway, railway, bridge
2.usedfor the safety of airport, port and wharf
3.usedas the safety measure for roads of scenic zone and hilly area
