BIRKDALE INTRODUCES ITS NEW DURAPOST^® SLEEPER POST

Birkdale has launched a new addition to its practical DuraPost^® range - the Sleeper T-Post. The new post has been designed to offer an ideal solution for constructing small to medium sized retaining walls. Easy to install, the post features 9mm pre-drilled holes and offers a tough and durable fixing method. 

The T-shaped design provides an ideal method for fixing sleepers to the post. It also features 9mm pre-drilled holes, which are then compatible with SITEMATE^® Flat-Head, Wafer-Head or Hex-head timber screws. 

Available in 1.2m, 1.5m, 2.0m and 2.4m lengths, the patented DuraPost^® Sleeper T-Post is made from roll-formed galvanised structural steel with an extremely durable pre-galvanised coating to ensure the ultimate in corrosion resistance. The coating offers a 30 year life expectancy in C2 and C3 environments, as defined in ISO 12994-2:2017. 

While the T- Post can be used to build retaining garden walls up to 1.2m in height with a foundation depth of 1.2m, Birkdale recommends that a structural engineer is consulted on projects over 0.6m in height.
