Box Beam Guardrail

Median barrier is parallel with the highway and used to separate opposing directions of traffic on a divided highway or motorway. It is designed to reduce the risk of errant vehicles especially head-on crash which would be terrible if happens.

Considering the safety of people in the errant vehicle, median barriers should perform well in redirecting light vans, cars and trucks. Traditional concrete barriers is a very common type. Though it is effective and maintenance-free after installation, it should be a little more expensive in the initial cost and more severe injuries.

More and more states and countries prefer to choosing semi-rigid barriers such as w-beam guardrail, box beam guardrail, thrie beam guardrail or cable barriers.
