Sleeper Retainers, also known as RSJs (Rolled Steel Joists), I Beams, or H Beams, are versatile structural steel components that are commonly referred to as Universal Beams.
The unique shape of these metal beams makes them an excellent choice for Sleeper Retainers in a wide range of garden and construction projects, especially when paired with Railway Sleepers. This durable combination is perfect for retaining walls, raised flower beds, embankments, and providing structural support.
Each Sleeper Retainer is crafted from galvanised steel, ensuring exceptional protection against the elements and potential damage, thereby guaranteeing the longevity of the retaining structure. It is a highly dependable product suitable for long-term outdoor use. A steel post has superior strength and durability when it is compared to a similar concrete or wooden product and will prove to be a long-lasting and long-term solution for a retaining wall.
The dimensions of this metal Sleeper Retainer are 127mm x 76mm, with a total length of 1800mm and weighing 23.6kg. Sleeper RSJ posts are available in a variety of sizes, so you can find the perfect ones for your project. Our sizes include sizes 1200mm, 1500mm, and 2000mm. They can also be cut to length, which makes them even more versatile.
Sleeper RSJ posts are easy to install, even for DIY enthusiasts. They can be screwed or welded into place, depending on your preference.
Sleeper Retainer Posts offer a multitude of ways to elevate your garden to the next level, providing both functionality and aesthetic appeal. Whether you want to create raised flower beds, sturdy retaining walls, or reinforce embankments, Sleeper Retainer Posts are the ideal choice for these projects. The installation process varies depending on your specific application. Please see some guidance below.
When constructing a retaining wall or flower bed, it is recommended to bury the RSJ 50% of the total height of the bed. For instance, if your wall will be 120cm high, the post should be buried 60cm, making the 1800mm RSJ Sleeper Retainer beam ideal for the task at hand.
If you need to cut the galvanized steel beam, there are various methods available, such as using band saws, angle grinders, or oxyacetylene setups. Prioritize precise measurements before cutting and employ suitable personal protective equipment (PPE) along with necessary precautions. However, it is advisable to order the appropriate length of beams to avoid the need for cutting, as they are available in different sizes.
To securely anchor the steel beam into the ground, we recommend using a product like Post Mix. Typically, two bags should suffice per post, but it is prudent to consult a professional for guidance to ensure the safety of your construction. The two holes indicate the bottom of the post, which should be buried into the ground.
To prolong its life it is a good idea to paint the steel RSJ with a good quality outdoor metal paint.
