Multi Applicational Safety System

The MASS Barrier is a steel base unit providing the foundations for five top sections designed to suit different site specifications.

MASS can be used in a range of sectors including aviation, nuclear, and construction, and has been used effectively in urban areas to segregate pedestrians and protect against traffic.

With a brilliant record in city centre vehicle/ pedestrian segregation and protection scenarios.

MASS Barrier Specifications

The hot dip galvanised and powder coated steel units are quick and easy to assemble due to unique plug-in sections. The swift installation process ensures maximum protection quickly with a minimum impact to traffic-flow. MASS is specially designed to self-stabilise when an errant vehicle drives onto the base units of the system, helping to protect the workforce and vehicle occupants. The base units are not fixed to the road, with an anchorage consisting of a steel buffer filled with sandbags at the terminal sections only.

No coring or drilling

For systems not requiring EN1317 level protection, no coring or drilling into the road is necessary, meaning installation can be quickly achieved with minimal tools and a team consisting of only four operatives or more.

All our MASS products are offered as rental or purchase.

MASS Corner Unit

MASS barriers provide the flexibility to curve, bend or angle where those site configurations are required.

Using a series of vertical pins and corner units, it is possible to easily rotate by 180° allowing a maximum angle between each base unit of a 90° bend.

These corner units allows for extra flexibility when each optional top section is required to follow a curve, bend or angle.
