Innovative, cost effective solution for safety barrier applications

Vetex normal containment (N2) system combines safety performance with installation convenience. Vetex® N2 is an innovative, cost effective solution for safety barrier applications. Normal containment barrier is designed to contain average vehicles, e.g. small and large cars <1500kg etc. This is used on motorways, major roads and minor roads. EN1317 details various performance classes for normal containment barrier.

Vetex® N2 has been designed with collapsible elements to absorb impact energy, assisting safety performance. Vetex® N2 design protects occupants from vehicle crossovers and safely redirects the vehicle back onto the highway.

Many working widths to chose from:

  • Several post spacing options
  • Acceleration Severity Index (ASI) A class on several options
  • Fully compatible with existing UK steel barrier systems
  • Untensioned for quick, easy installation and low maintenance
  • Approved by the Highways Agency

EN-Construction-Product-Vetex normal containment | Application

Application
  • On and off the road, in normal containment risk areas e.g. central reserves, verges and protection from impact with obstructions
  • High speed roads, including motorways, trunk and non-trunk roads
  • New build projects
  • Can be integrated with existing barrier runs: ideal for refurbishment, extensions and maintenance projects

Designed to contain very large vehicles

Vetex higher containment (H2) system combines safety performance with installation convenience. Vetex H2 is an innovative, cost effective solution for safety barrier applications which are designed to contain very large vehicles, e.g. coaches, curtained lorries etc.

This is used on motorways, in high-risk areas, such as bridges, gantries, concrete abutments, and off the road to protect machinery or buildings. EN1317 details various performance classes for high containment barrier. Tata Steel high containment barrier is H2 class, which can contain vehicles of up to 13,000kg vehicle mass.

Vetex H2 has been designed with collapsible elements to absorb impact energy, assisting safety performance. The Vetex H2 design protects occupants from vehicle crossovers and safely redirects the vehicle back onto the highway.

  • Same working width as Double Rail Open Box Beam (DROBB), with a higher performance class
  • H2W4 @ 2m post spacing
  • Acceleration Severity Index (ASI) B class
  • Fully compatible with existing UK steel barrier systems
  • Untensioned for quick, easy installation and low maintenance
  • Suitable for all ground types traditionally specified
  • Approved by the Highways Agency

<ul> <li>Vetex® P1 end terminal effectively anchors and terminates barrier runs thus offering a cost effective alternative to existing P1 terminals</li> <li>Straight ended detail enables installation where space is limited</li> <li>Suitable for new build projects</li> <li>Can be integrated with existing barrier runs; ideal for maintenance, repair and refurbishment</li> </ul>

EN-Construction-Product-Vetex end terminals - P1 End Terminal | Expert design and engineering

Expert design and engineering

<ul> <li>Safety is at the heart of Tata Steel Highways safety barrier development. The patented Vetex®  terminals have been engineered to offer a safer alternative to traditional terminals</li> <li>Vetex® terminals have been specifically designed to assist in the redirection of ramped impacts in a safe and controlled way. A discrete, sloping end detail to below ground yields a robust anchorage, while ensuring that key anchorage components do not create a hazard to errant vehicles. The Vetex® design allows a vehicle to mount the terminal smoothly, without snagging, and redirects it onto the ground, giving an improved level of safety for vehicle occupants</li> <li>With Vetex® terminals, vehicle and barrier damge is generally lower than for collapsible mechanisms. Therefore, Vetex® terminals maintain anchorage of the adjacent barrier, which means that the barrier maintains safety performance and can still be effective after impact</li> </ul>
