Description

Standard Unit Trip Rail, also known as Knee Rail, is a low-profile boundary solution widely used across parks, schools, housing schemes, and car parks. It provides a discreet, cost-effective way to indicate boundaries and restrict vehicle or foot traffic without compromising visibility or landscape aesthetics.

Supplied as 1500 mm welded units, the system is available with either flat bar or circular steel posts, offering design flexibility to suit modern or traditional environments. Each unit is manufactured from mild steel sections—solid S275JR and hollow S235JR—hot dip galvanised for weather resistance, with optional polyester powder-coating in any RAL colour. Its modular nature ensures fast and straightforward installation.

Features & Benefits

Sleek and low-profile – Maintains open visibility while providing an effective visual and physical boundary

Design flexibility – Available with either flat bar or circular upright post designs

Modular panel format – 1500 mm welded units support quick installation and easy specification

Robust steel build – Fabricated from durable S275JR solid and S235JR hollow mild steel sections

Corrosion resistant – Hot dip galvanised to EN ISO 1461 for long-lasting performance outdoors

Optional colour coating – Polyester powder-coated finish available in any RAL shade

Simple installation – Pre-fabricated panels with minimal fixings reduce on-site labour and time
