Types of Highway Crash Barriers
TMR Traffic Safety manufactures a complete range of metal beam crash barriers to meet diverse highway safety requirements
| Barrier Type | Profile | Best For | Impact Severity |
|---|---|---|---|
| W-Beam | Single or double corrugated wave | Standard highways, urban roads | Moderate to high |
| Thrie Beam | Triple corrugated wave | High-speed highways, dangerous curves | High to very high |
W-Beam Crash Barriers
Our W-beam crash barriers are the most widely used road safety barriers in India. The distinctive 'W' shaped profile provides excellent strength-to-weight ratio and effective energy absorption during vehicle impacts.
Key Features:
- Single Beam Barriers – Standard protection for moderate-speed roads
- Double Beam Barriers – Enhanced protection for high-speed highways
- W-Beam Guardrails – Flexible barrier systems for various applications
Thrie Beam Crash Barriers
Thrie beam crash barriers feature a triple-corrugated profile that provides superior rigidity compared to W-beam systems. These barriers are ideal for locations requiring maximum protection.
Key Features:
- 50% higher rigidity than W-beam
- Better containment of larger vehicles
- Ideal for locations with severe crash potential
Terminals & End Treatments
Proper crash barrier terminals and end treatments are critical for barrier performance. We manufacture fish tail terminals, ET-2000 systems, and transition sections that prevent spearing hazards.
Key Features:
- Fish Tail Terminals – Standard curved ends
- ET-2000 Systems – Energy absorbing terminals
- Transition Sections – Smooth barrier connections

Applications of Metal Beam Crash Barriers
TMR Traffic Safety highway crash barriers protect motorists across diverse infrastructure projects
National & State Highways
Our barriers line thousands of kilometers of NHAI projects and state highway improvements, providing essential protection on high-speed corridors.
Bridges & Flyovers
Bridge approaches and flyover edges require robust protection. Our road safety barriers prevent vehicles from leaving elevated structures.
Dangerous Curves & Sharp Turns
Horizontal curves with limited sight distance and sharp turns benefit from our high-containment barrier systems.
Median Barriers
Preventing cross-median collisions on divided highways with our double-sided barrier installations.
Hilly & Mountain Roads
Steep gradients and hairpin bends in terrain require specialized barrier solutions that we customize for each project.
Urban Roads & Ring Roads
City infrastructure including expressways and ring roads use our barriers for pedestrian and vehicle protection.
