EVA rotating barrel guardrail

EVA rotating barrel guardrail is a traffic safety facility, mainly composed of columns, beams, rotating barrels, and sleeves. The main material is a composite material of EVA and polyurethane. The "one column and four guardrails" installation method enhances the overall performance of the column and guardrail, effectively preventing vehicles from breaking through the guardrail and driving out of the lane. In the event of a collision, the guardrail adopts a free rotation design, and its rotating barrel structure can convert vertical impact force into parallel force. At the same time, the elastic material in the rotating barrel absorbs and mitigates the impact energy, thereby effectively reducing the damage caused by traffic accidents.

Rotating barrel size	commonly 350mm×238mm (diameter×height), some customized products can reach 600 mm in length.
Column size	generally 140mm×4.5mm×2160mm (diameter×wall thickness×height), spacing is about 700mm±50mm.
Weight	The weight of a single rotating barrel is about 20kg, and the overall weight of a customized large guardrail can reach 1111kg (depending on length and configuration).
Material and structure
Rotating barrel material	EVA blend or high-strength EVA+polyurethane composite material, with high elasticity, anti-collision and wear resistance, chemical corrosion resistance, UV aging resistance, and a service life of more than 10 years.
Column material	high-quality carbon structural steel, hot-dip galvanized surface, zinc layer adhesion column ≥ 600g/m², fastener ≥ 350g/m².
Color and warning
Color	Yellow, orange, green and other colors are available, and reflective film (class IV and above) is supported to enhance the night warning effect.
Collision-proof performance
Collision-proof level	SB/SBm level, through small car and large truck collision tests, can decompose the impact force to parallel directions, reducing accident mortality by more than 90%.
