A road crash barrier is engineered to absorb impact energy and redirect a vehicle away from a hazard — rather than simply stopping it dead. SinoBarrier manufactures metal beam and rolling barrier systems for highways and high-risk sites, crash-tested to MASH TL3 / TL4.
How crash barriers absorb energy
- Beam deflection — the corrugated section flexes and transfers load along the run to the posts.
- Post yielding — the posts deform in a controlled way, absorbing a share of the impact.
- Roller rotation — rolling barrier systems convert impact energy into rotation, steering the vehicle along the barrier.
Systems for crash-critical locations
| Location | Recommended system |
|---|---|
| Highway curves | Thrie-beam or rolling barrier |
| Bridge approaches | Thrie-beam with bridge end terminals |
| Tunnels | Rolling barrier (confined cross-section) |
| Median separation | W-beam or double-sided barrier |
| Accident-prone sections | Rolling barrier retrofit |
