Rolling Guard Rail System Traffic Safety EVA PU Highway Roadway
Roller Barriers
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
High quality steel support
Using Q235 steel, multiple thick steel fixed, durable, strong
protection ability.
Strong of lower solid frame
The round post could buried deep, structural strengthening, can
effectively block the front or side impact.
Advantage of Roller Barrier
1. The build-in handle and flexible clasp banner simplify handling
and portability.
2. Locking castors can be fixed at the bottom to ease over. And the
castors are optional.
3. Bolts on the flank can be attached to another barrier.
4. The Eco-friendly coated powder is available for both indoor and
outdoor applications.
5. The structures in the posts make the barrier folding and
expanding flexible.
6. All the rivets used in the product are stainless with high
quality.
7. Available in many color combinations.
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.
Application field:
The product can be widely used in highway curves.
Highway ramps and continuous downhill sections.
Midsection of curved belt.
Part of a cliff or high drop slope.
Bridge the dock.
Areas affected by crosswind.
Tunnel entrance.
And accident-prone roads.
