Guardrail barriers provide semi-rigid protection to shield motorists from hazards located close to the edge of the travelled way.
The most common guardrail system consists of a steel W-Beam rail on steel posts with end treatments and transitions of various designs using similar materials. The W-Beam type safety barrier shall consist of a steel post and a 3mm thick ‘W’ Beam rail element.
The steel post and the blocking out spacer shall both be channel section of 75mm x 150mm size and 5mm thick. The rail shall be 70 cm above the ground level and posts shall be spaced 2m center-to-center. A double ‘W’ Beam barrier shall be as indicated in IRC:5-1998.
SAFETY BARRIER APPLICATIONS
Valmont’s guardrails are manufactured using the Cold Roll Forming Technology with multiple roll forming stations ensuring greater strength due to grain reorientation as compared to the normal press-formed sections. These sections are of ‘W’ and Thrie-Beam shapes with a thickness of 3mm.
Following are some of the applications of these safety barrier systems:
- Highways, Flyovers & Bridges
- Median Barriers as Road Separators
- Protection from Trees, Rocky Areas etc.
- Hilly Terrain, High Embankments etc.
- Test Tracks in Automobile Industry
- Mass Housing Complexes/Townships.
- Airports, Railway Stations and Parking Lots
