The Snowdon Timber 5 Step Treated Decking Riser is ideal for DIY enthusiasts and professional landscapers looking to build robust outdoor staircases or garden tiers. These pre-cut, pressure-treated components provide exceptional structural integrity and long-lasting resistance to moisture and decay, making them perfect for exterior environments. While they offer superior durability, users should note that they require precise site measurement and appropriate heavy-duty fixings to ensure a secure and level installation for the intended staircase height.

Always pre-drill pilot holes before inserting screws to prevent the wood from splitting, especially when working near the edges.
To install, ensure your base is level and use galvanized or stainless steel screws to attach the risers to your staircase stringers to prevent corrosion. Compatibility is best maintained by using matching treated timber for treads and stringers to ensure uniform movement and weathering.
