Steel Sleeper Posts

Enhance your garden by creating sleeper retaining walls with our range of strong and high quality galvanised steel RSJ sleeper posts.

Sleeper retainer posts, also known as RSJs (Rolled Steel Joists) are a common sight in construction and structural work. They are highly versatile and can be used for a wide range of applications. Their easily recognisable I shaped profile makes them the ideal choice for supporting railway sleepers.

Available in 1200mm, 1500mm, 1800mm and 2000mm lengths, offering a great level of versatility when creating your perfect garden.

The 127mm x 76mm dimensions of these sleeper retaining wall posts allows the railway sleepers to fit comfortably into the gaps and be held securely.

Each of these sleeper retaining posts has been made from high quality galvanised steel. The zinc coating on these sleeper retaining wall posts forms a protective layer against the elements. This helps to reduce rust and corrosion formation and ensuring that these posts will remain strong and stable for many years to come.
