Rolling Guard Rail System Traffic Safety EVA PU Highway Roadway Roller Barriers
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.
