According to the shapes of highway guardrails, they can be divided into four main types: W-beam guardrail, thrie beam guardrail, box beam guardrail and cable guardrail. We Xiamen Bogong Machinery can custom manufacture the first three types of highway guardrail roll forming equipments.

• W-beam guardrail is a kind of road crash barrier used for securing highway safety by preventing errant vehicles from sliding out of the roads and impacting the roadside buildings or other objects. So it is most commonly fixed on the side of the highways, dock areas, aisles, especially on curves and slopes for protection against run-off-road collisions.

• The W-beam guardrail product is formed in accordance with the latest highway safety barrier technology for making sure its high durability and maximum strength. It is made of high quality steel, which reduces the impact force caused by mobile equipment to the maximum extent. Meanwhile, the zinc coating or PVC coating perfectly combined to the W-beam guardrail keeps the products free of damages of corrosion and rust.

• Thrie beam guardrail features its shape of three waves, which has an added corrugation on the basic of traditional W-beam. Compared to two-wave shape products, this one has a stronger construction and higher impact endurance. It has been successfully impact-tested by a heavy truck and has showed its remarkable resistance against the crash force.

• It is a perfect combination of high quality material (including Q235, Q345, etc.) and excellent anti-rust zinc or PVC coating. All of these make it outstanding at long-term corrosion and rust resistance. Meanwhile, it costs effectively and is widely used as a visual and physical barrier for protection against run-off road collision. Additionally, it is often used as a specific signs for a transition to high speed roadways, bridges, etc.

• 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.
