about Cable Barrier
Cable Barrier, also known as cable guardrail, wire rope safety barrier. Cable Barrier System is a flexible guard railing system to provide good safe guard in open areas. This barrier system composed with chiefly hot dipped galvanized steel wire strands, steel posts and terminals offering excellent rust resisting and corrosion resisting property.
This type of wire rope safety barrier is a kind of highway fence keeping vehicles within 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 steel post at certain spacing to form a flexible guard barrier. The more number of the wire cables, the much strength the barrier offers.
Advantages
1.Low cost, Easy to install and repair
2. Less impact on accident car and the persons inside
3. Cable tension and Post space can be adjusted
4. Prevent vehicles from running off the road effectively
5. Absorb most sudden impact energy during collision
6. Can be reused after accident by somehow repairment
7. Anti-rust, anti-corrosion and anti-aging
8. Good looking for open scenic spots
Application
1.used for the sides of highway, railway, bridge
2.used for the safety of airport, port and wharf
3.used as the safety measure for roads of scenic zone and hilly area
Details about Cables
The barriers are manufactured with 3x7 high tensile steel cables, the most commonly used are 18mm and 19mm steel wire ropes. A 3x7 steel wire rope has three strands, 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 corrosion and rusting.

Three Major Factors on Efficiency of Cable Barriers
1. Cable numbers: Three of four cables are commonly used. Five or six layer wire cables are used for reinforced guard railings.
2.The barrier post often installed with spacing from1.2m-4.0m.
3. Tensioning: Cables are fixed on the post and tightened to specific tension in accordance with the local temperature and environment. After tension, the reflection will be reduces and the ability to preventing vehicles from skidding off the road can be enhanced.
