With the Douglas fir I/III re-sorted KD grooved decking boards 26 × 145 mm, you receive high-quality, kiln-dried, and dimensionally stable terrace timber that impresses with its natural beauty, high resistance, and an attractive price-performance ratio. Douglas fir is a traditional yet modern choice for deck construction and offers a good alternative to Siberian larch.

The Douglas fir decking boards are characterized by their light, reddish-brown color and distinctive grain, which gives every terrace a warm, vibrant appearance. The grooved surface additionally provides an anti-slip structure and highlights the natural look of the wood.

As a medium-hard softwood species, Douglas fir is excellent to work with – sawing, drilling, or sanding is easily possible with standard tools. Kiln drying (KD) to a wood moisture content of 16–18% enables high dimensional stability – well-suited for long-lasting and precise outdoor installation.

The natural durability of Douglas fir (class 3–4 according to DIN EN 350-2) makes it ideally suited for outdoor use, particularly for terraces, paths, or garden areas. The service life can be further extended through structural wood protection, sufficient ventilation, and proper installation.

For secure fastening, pre-drilling is strongly recommended to prevent cracking and damage. Use only stainless steel screws (at least grade A2) to exclude discoloration caused by ferrous metals. During installation, a gap width of at least 4 mm should be maintained to account for the natural swelling and shrinkage behavior of the wood.
