Outdoor Mill Staircases in Douglas Fir or Planed Larch – Natural Durability and Authentic Aesthetics

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.

Available materials

Douglas fir: naturally durable French timber (class 3), stable and rot-resistant without treatment.
Larch: dense and decorative alpine species, excellent resistance in damp conditions.

Douglas fir vs Larch: which species to choose for your outdoor staircase?

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

Please note: natural cracks in solid wood

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.

Natural phenomenon: shrinkage of the wood during air drying.
Enhanced aesthetics: gives the wood a raw and natural appearance.
No structural impact: mechanical performance is maintained.

Installation tips

Install the staircase on a stable, flat and well-drained surface.
Secure the uprights with the brackets provided.
Pre-drill the treads before screwing to avoid splitting.
Apply a water-repellent treatment (oil or wood stain) before first exposure.

Frequently asked questions

How do you install an outdoor wooden staircase in Douglas fir or Larch?

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.

What is the lifespan of an outdoor staircase in Douglas fir or Larch?

Outdoors, these species can last between 15 and 25 years depending on maintenance. Annual oiling extends the durability of the wood against the weather.

Is Larch more resistant than Douglas fir?

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.

Should an outdoor wooden staircase be treated?

Yes, although naturally durable, these woods require protection with oil, saturating oil or wood stain to preserve their colour and prevent greying.

Can this staircase be installed on a terrace or sloped garden?

Yes, the adjustable design of the staircase allows adaptation on a slightly sloped surface. Ensure a stable base and secure anchorage to the ground.
