Trip Rail / Trip Fence / Knee Rail

Trip rail or knee rail offers protection to grassed or planted areas. They also act as an effective deterrent to drivers who would otherwise seek to park free of charge away from public highways.

Our standard metal trip rail is fabricated using circular or square hollow section mild steel. As a more contemporary option, trip rail can also be offered with flat bar posts as shown on image 4 in the gallery below. This is then hot-dipped galvanised to offer long term rust protection and can be polyester powder coated in any RAL colour thereafter. This ensures a long lasting, hard working product. We have manufactured a variety of differing trip rails in our time, many of which can be seen in the photos below. We believe that steel trip rails offer long term value for money in comparison to a timber alternative which may be cheaper at the outset, but is more prone to vandalism and would require frequent maintenance.

We can manufacture designs that are both aesthetically pleasing and effective at deterring people and vehicles from trampling over areas that need protection Sometimes alternative materials may be used to make trip rail such as wood, particularly if cost is an consideration as these materials can be a cheaper alternative.
