Outdoor Timber Stair Kits are quality pre-fabricated DIY outdoor wooden stairs and steps, giving a professional finish whilst saving you both time and money.

Stair Treads are 900mm wide and can be made to any width, we use quality DAR Pine Treads and DAR Merbau Treads. The Stair Kit comes with matching stringers which are fully trenched out from back and pre-drilled, the rise is 160mm between each step.

We can customise the stairs to suit your requirements and can manufacture to any width. For a quote we require measurement to be made from Landing to ground height, the width required for the Stair treads and whether you require Treated Pine or Merbau.

We are located in Melbourne and able to provide delivery throughout Australia on our range of internal and outdoor wooden stairs.
