Component details
This guardrail consists of uprights, EVA rotating barrels, U-shaped
beams and connectors. All steel components are treated with hot-dip
galvanizing to prevent rusting.
The vertical pillars are separated by 1 meter or 0.7 meters, and
two rotating barrels are installed on each vertical pillar.
Product features
This rotating barrel is made of EVA (ethylene-vinyl acetate
copolymer) as the main material, added by more than 30 kinds of
auxiliary materials such as PE (polyethylene) and related chemical
additives, and was produced under a certain temperature and
pressure. With high flexibility and resilience, and also with high
temperature resistance, continuous working temperature between -30
°C and 70 °C.
Reflective strips are attached to the rotating barrel. When driving
at night, through the illumination of head-lights, it can better
reflect the outline of the route, play a better sight-inducing role
for the vehicle, improving driving safely.
