Trief® Kerb
The ultimate in visual and
physical deterrent
The famous Trief Kerb was first introduced to the UK in 1962 and
ever since has made a substantial contribution to traffic control
and safety on our roads.
For highway applications where the
highest level of visual and physical
deterrence is essential, the original
Trief Kerb is the obvious choice. Its
dependability has been demonstrated
repeatedly in use, proving that its
single-unit design is the best available
and significantly increases road
safety.
Multiple uses
Designed for all environments
where the need to contain vehicles
is paramount, the Trief Kerb
delivers proven safety on major
highways, service stations,
warehouses, dockyards and other
areas. The versatile Trief Kerb:
- Prevents... vehicles from
accidentally leaving the
carriageway, encroaching onto
roundabouts and other areas
and parking randomly
- Controls... by forming traffic
management and calming
measures such as roadside
vertical deflections and
pedestrian refuges
- Protects... by safeguarding
verges and landscaped areas
from vehicle and pedestrian
incursion, shielding structures in
heavy traffic areas, protecting
petrol islands and people and
parapets on bridges
- Deters... by creating an
imposing visual warning that
prompts drivers to steer away
High-level safety and practicality
Design 'and
installation
The modular design of the Trief
Kerb makes it simple to install
and use. With over 30 standard
units in the range including
quadrants and radius kerbs, a
huge variety of design layouts
can be created.
Two finishes
The Trief Kerb is available in two
finishes to create the results
required:
Standard Finish: a natural finish Textured: with a subtle, slightly
with a smooth matt surface aged finish to complement
existing environments such as
conservation and heritage
