Box beam guardrail, a kind of highway barrier, is not as common as traditional W beam or thrie beam guardrails, but it caters the need of appreciation of the beauty and is widely used not only on highways, but also in parks, picturesque bridges, etc.
The same as W-beam guardrails, it is made of high quality steel and plated with superior zinc coating or coated with PVC coating. Thereby, it is anti-rust and durable enough to endure the impact force. Additionally, there is no need of paying much money on the maintenance of the box beam guardrail, which makes it cost effectively in the long run.
