Highway Safety Guardrail Anti-Collision Proof Roller Rotating Crash
Barrier
The Rolling Barrier Guardrail was built with maintenance as a
primary concern. A modular design comprised of D-shaped steel
rails, round steel-posts with EVA shock-absorbing barrels, and
frame rail lockers means that after incidents, individual parts can
be replaced without compromising the entire system thus reducing
maintenance costs.
Improve roadside visibility – SRB rollers are striped with
high-intensity reflective sheeting that increases driver awareness
and reduces accidents. Optional LED guide lamps can be added for
even more exceptional visibility.
Safely redirects vehicles – Shock absorbing rollers convert impact
energy into rotational energy, creating a smooth redirection.
Occupant impact test results show SRB is the safest in its class.
Soften vehicle impacts – With 100% recyclable components, SRB is
made of steel and flame-retardant, eco-friendly ethylene vinyl
acetate (EVA) plastic, which softens vehicle impacts and reduces
vehicle damage.
Wear resistance is higher than 200% Wear resistance is higher than
200% to other anti-collision barrel materials in the market . Due
to its unique production process and process, Taicheng Rotary
Anti-collision Barrel has 3mm thick hard polyurethane protective
layer in the outer layer of the barrel. Its tensile strength and
bearing capacity are 2-3 times that of other anti-collision barrels
in the market.
