System Principle

1.      Wave shaped guardrail, it is a corrugated steel fence panels to each other by stitching a continuous post supporting the whole structure.

2.      It uses soil base, column, beam deformation to absorb impact energy and force out of control vehicle to change direction and return to the normal driving direction, to prevent the vehicle runs off the road, to protect the vehicles and passengers, to reduce losses caused by the accident.

3.      Waveform phase and flexible steel beam guardrail, and a strong ability to absorb crash energy, and has good sight induced features can be coordinated with the road alignment, beautiful appearance, can be used in a small radius curve, the defects were easy to replace.
