Straight mill staircase supplied as a kit, step height 20 cm. 14 steps, width from 60 to 90 cm (excluding handrail). Available with or without handrail.
Combine strength and natural elegance with our outdoor solid wood staircases, designed to withstand all weather conditions while enhancing your outdoor spaces. Available in Douglas fir or planed Larch, these species offer natural structural durability without chemical treatment. Their robust construction in planed solid wood ensures stability and comfort of use, while retaining a warm appearance suited to terraces, gardens or outdoor mezzanine access. Both species are distinguished by their hues and density, allowing a choice suited to each project, according to the desired style and site exposure.

Both species are recognised for their natural durability. Douglas fir is valued for its excellent value for money and stability, while Larch stands out for its density and superior longevity. This comparison helps you choose according to your needs:
| Criterion | Douglas fir | Larch |
|---|---|---|
| Natural durability | Very good – Class 3 (without treatment) | Excellent – Class 3-4, very dense |
| Appearance | Pinkish hue, straight and subtle grain | Golden brown hue, pronounced grain |
| Average density | ≈ 550 kg/m³ | ≈ 650–700 kg/m³ |
| Natural cracks (checking) | Present, barely noticeable | More visible, no effect on resistance |
| Maintenance | Exterior oil or saturating oil recommended | Oil or UV-resistant wood stain |
| Budget | More economical | Slightly more expensive |
Douglas fir and Larch sometimes display fine surface cracks known as checking. This natural phenomenon results from the drying of the wood and does not affect its mechanical resistance in any way. These marks add an authentic and rustic touch to your outdoor space.
Personalise your staircase with a matching handrail and protect it durably with our range of wood finishes suitable for outdoor use:
Assemble the stringers and treads on a flat base, then secure the whole unit with the brackets provided. Use a spirit level to adjust the slope and apply a protective treatment before use.
Outdoors, these species can last between 15 and 25 years depending on maintenance. Annual oiling extends the durability of the wood against the weather.
Yes, Larch is denser and offers better mechanical and moisture resistance, making it ideal for highly exposed areas. Douglas fir remains an excellent economical and stable choice for temperate regions.
Yes, although naturally durable, these woods require protection with oil, saturating oil or wood stain to preserve their colour and prevent greying.
Yes, the adjustable design of the staircase allows adaptation on a slightly sloped surface. Ensure a stable base and secure anchorage to the ground.
