The Trief GST2A kerb is a passive safety system designed to contain and re-direct vehicles safely back onto carriageways, avoiding injury to pedestrians, damage to local structures and damage to the driver and their vehicle.

Designed with the same profile as the standard Trief® (GST2A) system but with a reduced height, the Brett Trief® (GST2) Shallow Kerb system is suitable for installation in applications with restricted depths. It has the option of bonded installation methods.

The wider Trief GST2A containment Kerb system consists of various components, including quadrants, short lengths, and radius and transition kerbs. Typically supplied in a smooth concrete finish, it is also available in an exposed aggregate finish or natural granite to suit various project aesthetics. This allows for a wide range of design possibilities, addressing most site-specific constraints and safety considerations, and the use of transition kerbs allows Trief Kerbs to be seamlessly integrated into existing British Standard kerbs.
