Cable barrier, also called guard cable or wire road safety barrier (WRSB for short) is getting popular in roadside or median road applications. It includes steel cable and steel posts like H posts. As a result of lower installation cost and effectiveness at controlling vehicles, cable guardrail is increasingly applied by highways or motorways.
Depending on tension strength, cable barrier can be divided into low-tension and high-tension type. Each type has its own advantages and disadvantages. However, a high-tension cable barrier system will benefit you more in the long term. If you are not sure which type is right for you, call us for professional advice.
