Waveform guardrail is rigid and flexible, has a strong ability to absorb collision energy, has a good line of sight induction function, can be coordinated with the highway line shape, beautiful appearance, damage is easy to replace. Waveform guardrail than concrete guardrail has a certain permeability, at the same time has a relatively low engineering cost characteristics, can be used for high aesthetic requirements of the road and the desert, snow areas.Corrugated beam guardrail is the main form of semi-rigid guardrail, it is a corrugated steel guardrail plate spliced and supported by the main column of the continuous structure. It uses the soil base, column, beam deformation to absorb the collision energy, and force the runaway vehicle to change direction, back to the normal direction of travel, to prevent the vehicle from rushing out of the road. To protect the vehicle and passengers, reduce the loss caused by the accident. Corrugated beam guardrail steel and flexible, has a strong ability to absorb collision energy, has a good line of sight induction function, can be coordinated with the road shape, beautiful appearance, can be used in small radius curves, damage is easy to replace. Combined waveform beam guardrail can be used in the narrow central divider. For vehicles crossing the road (bridge) outside, may cause serious consequences of the section, can choose to strengthen the waveform beam guardrail.Waveform guardrail has good impact resistance, low cost, long life, anti-corrosion performance, safety. Higher, green, easy and fast installation and other advantages. Highway waveform guardrail plate material is high-quality steel plate by anti-corrosion treatment.
