Guardrail whosesafety has been reinforced by strengthening structural functions and enhancing sustaining power according to the amendments to the Vehicle Protection Safety Facilitiesfor Banking Sections
[Product Features]
- A function to enhance an insufficient earth pressure on the incline of the banking section by attaching the “W”-shaped bent brace plates to the underneathof the prop.
- The “W”-shaped bent brace plate, formed in three-dimensional shape, provides sustaining power in the several directions which shock is applied to.
- The “D”-shaped x-frame with a smooth front part prevents tire breakage of the accident vehicles and prevention of loss of steering function
- A simple structure with a “D”-shaped semicircular x-frame which has a self-shock absorption function does not need buffer bracket.
- The product can be designed to have a simple and narrow structure suitable for the enough roadside width is not secured.
- The product, whose track-type rail structure moves liquidly at collisions, reduces shock.
