Crash Barrier Highway Corrugated Plate Eva Roller Anti-Collision Guardrails Crash Barrier
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.
