Crash Barrier Highway Corrugated Plate Eva Roller Anti-Collision
Guardrails Crash Barrier
Roller EVA material with elastic characteristics is used as raw
material, which can slow down the lateral impact process of the
out-of-control vehicle. Moreover, the rotating barrel can rotate
around the column under a certain impact, driving the
out-of-control vehicle to return to the correct driving direction.
Fasteners: Hot dip galvanised or electro galvanised bolts, nuts and
washers conforming to IS 1367 of grade 4.6 MS. 16mm dia Button head
bolts for W-beam to W-beam & W-beam to spacer connection. 16mm dia
hexagonal head type bolts for spacer to post connection
Principle 1: Transforming the impact power into rotating kinetic
energy can greatly absorb the impact force and reduce the impact to
effectively reduce the consequences of traffic accidents.
Principles 2: The rotating barrel uses EVA and poly ammonia
composite materials. This material is elastic and anti -collision
-resistant and wear -resistant.
The rotary drum is made of EVA (ethylene-vinyl acetate copolymer)
as the main material, and more than 30 kinds of auxiliary materials
such as PE (polyethylene) and related chemical auxiliaries are
added at a certain temperature and pressure. It has high
flexibility and resilience, and also has high temperature
resistance, and continuous working temperature is between -30℃ and
70℃.
The reflective strip is attached to the rotating cylinder. When
driving at night, through the lighting of the headlights, the
outline of the route can be better reflected, and the vehicle can
play a better induction role to improve driving safety.
