Three-wave guardrails refer to guardrails with three wavy patterns, each wave being 85MM high. The three-wave pattern guardrails offer higher collision resistance, suitable for more dangerous road sections, such as highways, mountainous roads, and hazardous stretches.
Common specifications for double and triple wave guardrails:
Double Wave Guardrail Panel: 4320*310*85*3/4
Three-wave波形guardrail panels: 4320*506*85*3/4
Double Wave Pillar: 114/Ø140 mm × 4.5mm × height
Three-Section Poles: 114/Ø140mm × 4.5mm × height

In the event of an out-of-control vehicle colliding with a guardrail, it is naturally desired that the guardrail acts on the vehicle's effective areas, neither allowing the vehicle to pass over the guardrail nor to be forced beneath the guardrail's cross beams. An ideal scenario would be for the guardrail to exert its overall force, gradually steering the vehicle back to a normal driving direction. However, the wide variety of vehicles produced worldwide, ranging from heavy-duty trucks to compact microcars, exhibits significant differences in weight and design. Modern sedans are trending towards miniaturization, becoming lighter in weight. To reduce air resistance, their hoods are more streamlined and lower, which makes these vehicles more prone to sliding beneath the guardrail's wave beams, leading to severe consequences.
