Highway safety barriers separate traffic from hazards — oncoming lanes, steep drops, fixed objects and work zones. SinoBarrier manufactures steel and metal beam barrier systems in-house, galvanized to AASHTO M180 and crash-tested to MASH TL3 / TL4, for roads, medians and temporary work-zone protection.
Barrier types we supply
| Barrier type | Where it is used |
|---|---|
| W-beam guardrail | Standard highway runs, medians and ramps |
| Thrie-beam guardrail | Bridges, transitions and high-risk curves |
| Rolling barrier | Expressways and alignments needing energy absorption |
| Steel work-zone barrier | Temporary protection in construction and maintenance |
Choosing the right system
The correct barrier depends on three things: the road class, the speed, and what is behind the barrier. A wide-shoulder rural road needs a different system from a narrow median on an expressway. Send the road class and posted speed, and we recommend the beam profile, post spacing and test level.
Standards and documentation
All systems are hot-dip galvanized to AASHTO M180 and crash-tested to MASH. Mill test certificates, coating-weight reports and crash-test documentation ship with every order.
