W Beam / Thrie Beam metal Crash Barrier description:

Metal Beam Crash Barriers (MBCBs), as per NHAI and MoRTH norms, are made of high tensile hot-dip galvanized steel conforming to AASHTO M180 / IRC / MoRTH Section 810 standards. The barriers are generally of W-Beam (312 × 83 × 3 mm) or Thrie-Beam (507 × 83 × 3 mm) profiles, mounted on C, Z, or H-type posts spaced at 2.0 m. All components are hot-dip galvanized with 610 g/m² coating for corrosion resistance. Installed at a height of 700 mm ± 20 mm from ground level, these barriers are designed to absorb impact, reduce accident severity, and redirect vehicles safely, ensuring long-term road safety on highways, expressways, bridges and hilly terrains.

The products conform to national and international standards such as MORTH, AASHTOM 180 and EN 1317-1 and 2. What’s more, the quality-oriented company offers end-to-end solutions that embrace manufacturing as well as installation. Designed for safety, the W beam absorbs maximum energy during impact by flattening out and laterally limits the vehicle from swerving over. Impedes the vehicle from skidding back onto the roadway through curbed exit inclinations, gradual slowing down and operational projecting of the vehicle back onto the thoroughfare. Facilitates a beneficial visual representation to the drivers, especially after dark. Allows immediate repairs in case of accidents. Offers durability as all components are hot dip galvanised.

W Beam Crash Barrier: Guardrail barriers provide semi-rigid protection to shield motorists from hazards located close to the edge of the road. A typical guardrail system consists of a steel W-Beam rail on steel posts with various designs of end treatments and transitions made from the same material. The W-Beam type safety barrier consists of a steel post and a 3mm thick ‘W’ Beam rail element. The steel post and the spacer are 75mm x 150mm and 5mm thick segments. The rail is situated 70 cm above ground level and posts are spaced 2m center-to-center. A double ‘W’ Beam barrier conforms with the standards of in IRC: 5-1998.

Types of Metal Beam Crash Barriers
1. W-Beam Crash Barrier

Most widely used type.

Consists of “W”-shaped steel rails mounted on vertical posts.

Absorbs impact energy and redirects vehicles back to the road.

Suitable for highways, expressways, and hilly terrains.

2. Thrie-Beam Crash Barrier

Stronger than W-Beam (three-wave profile instead of two).

Provides higher containment and resistance.

Preferred for areas with heavy vehicle traffic, bridges, and steep embankments.

3. Median Crash Barrier

Installed on road medians to prevent head-on collisions.

Can be W-Beam or Thrie-Beam depending on site requirements.

4. Bridge/Parapet Crash Barrier

Specially designed barriers for bridges and flyovers.

Higher strength to prevent vehicles from falling off.

5. Customized/Combination Barriers

Combination of W-Beam & Thrie-Beam for specific site conditions.

Can be designed to meet IRC, MORTH, or AASHTO standards.

Metal Beam Crash Barriers (MBCBs) – Detailed FAQs
1. What are Metal Beam Crash Barriers (MBCBs)?

MBCBs are safety barriers made of galvanized steel beams (W-Beam or Thrie-Beam) mounted on posts. They absorb and redirect impact energy, preventing vehicles from leaving the roadway and reducing accident severity.

2. Why are MBCBs important in India?

India records one of the highest numbers of road accidents globally.

MBCBs protect vehicles from colliding with roadside hazards, steep slopes, and medians.

They are mandated on national highways, expressways, bridges, and hilly terrains as per MoRTH/IRC specifications.

3. What are the main types of MBCBs used in India?

W-Beam Crash Barriers – Standard type, widely used.

Thrie-Beam Crash Barriers – Heavier, stronger, suitable for bridges & high-risk zones.

Median Barriers – Prevent head-on collisions on divided highways.

Bridge Parapet Barriers – High-strength barriers on bridges & flyovers.

4. Which standards are followed in India?

MoRTH (Ministry of Road Transport & Highways) Specifications

IRC (Indian Roads Congress) Guidelines

AASHTO M180 (American Standard) for galvanization, beam profiles, and performance.

5. What is the difference between W-Beam and Thrie-Beam barriers?

W-Beam:

Two-wave profile

Cost-effective, general highway use

Deflection is slightly higher

Thrie-Beam:

Three-wave profile

Stronger, used for bridges, steep embankments, heavy traffic roads

Lower deflection, higher impact resistance

6. Where are MBCBs installed in India?

National and State Highways

Expressways

Flyovers & Bridges

Hill Roads / Ghats

Dangerous curves & embankments

Roadside hazards (culverts, trees, poles)

Medians (to prevent head-on collisions)

7. What materials are used?

High Tensile Steel (IS 5986/2062)

Hot-Dip Galvanization (610 g/m² or as per AASHTO M180) for corrosion resistance

Posts & Fasteners also galvanized for long life

8. How long does a crash barrier last?

Typically 20–30 years with proper galvanization.

In coastal or highly humid areas, additional protective coating may be required.

9. Can damaged barriers be repaired?

Yes 

Damaged rails (beams) or posts can be replaced individually.

No need to dismantle the entire stretch.

This makes them more economical compared to concrete barriers.

10. What is the cost of installation in India?

Cost depends on:

Type (W-Beam / Thrie-Beam)

Length of barrier

Galvanization thickness

Location (plain, bridge, or hilly terrain)

11. How are crash barriers tested?

Full-Scale Crash Tests are conducted as per MoRTH & IRC guidelines.

Tests check:

Impact absorption

Vehicle redirection capability

Deflection (how far the beam bends)

Safety of vehicle occupants

12. What is the typical size/structure of an MBCB?

W-Beam Profile: 312 mm × 83 mm × 3 mm thick

Thrie-Beam Profile: 507 mm × 83 mm × 3 mm thick

Posts: C-Post, Z-Post, or H-Post (1.8 m–2.5 m high, depending on site)

Spacing: Posts installed at 2 m (standard) or 1.5 m (for stronger requirement)

13. What are the advantages of using MBCBs in India?

Saves lives by reducing accident severity

Easy to install & repair

Cost-effective compared to RCC barriers

Durable (20+ years with galvanization)

Flexible design for highways, hills, and bridges

14. Who are the approving authorities in India?

MoRTH (Ministry of Road Transport & Highways)

NHAI (National Highways Authority of India)

State PWD / R&B Departments

IRC (Indian Roads Congress) – technical guidelines

15. Are MBCBs mandatory in India?

Yes 

As per MoRTH & IRC codes, crash barriers are mandatory on highways, expressways, flyovers, and accident-prone zones.
