T-18 LogRail

The T-18 Log Rail element is constructed from Douglas Fir log (18 mm diameter), combining the natural beauty of wood with the strength of steel, to produce an aesthetic appealing road traffic barrier system.

Revered as the industry leader in mixed wood and steel guardrail systems, more than 1500km of T-18 Log Rail have been installed worldwide.

T-18 Log Rail provides vehicle containment and re-direction through a steel U-channel which is factory-fitted into the rear of the log.

A specially engineered fishplate (using only 3 bolts to secure the rails to the supporting posts) is used to splice the rail elements.

The supporting posts of the barrier system consist of a steel C-section that is driven directly into the ground and fitted with timber cladding (18 mm diameter).

All the components comprising the T-18 Log Rail road barrier system effectively work together, to provide the necessary tensile strength required for safe vehicle re-direction and containment.

How do T-18 Log Rails work?

The T-18 Log Rail relies upon the combination of the tensile strength of the steel components and the energy-absorbing characteristics of wood, to safely redirect an errant vehicle in a collision.

Upon impact, the posts absorb some of the crash energy through the post’s rotation into the surrounding soil, prior to their separation from the rail as they fully yield.

Once the connection bolt shears, the rail is released from the supporting posts.

Following the rail’s separation from the posts, the rail forms a re-directive ribbon, guiding the vehicle away from the nearby hazard.

Features and Benefits

  • T-18 Log Rail is supplied in standard 4m lengths and can be installed with posts spaced every 2m or 4m, providing design flexibility (depending upon the available clearance from the traffic barrier to the roadside hazard).
  • Pressure-treated Douglas Fir wood is used for construction to enhance rail durability.
  • Timber clad components are used for optimum performance and aesthetic appeal.
  • The steel backing is factory fitted to the rail log and the assembly of the fish-plate component requires only 3 bolts, facilitating rapid installation.
  • The steel posts of the road barrier system are driven directly into the ground for anchored strength reinforcement.

Safe Direction’s T-18 Log Rail has been successfully evaluated with posts spaced at 2m and 4m centres, meeting the requirements of European Standard EN1317 Parts 1 & 2, Containment Class N2.
