Species

Kebony Clear, the beauty of natural wood enhanced by technology

Kebony Clear® is an FSC® certified softwood modified using patented technology based on plant-derived bio-liquids. This process durably improves its resistance, stability, and durability, without the addition of toxic substances. Over time, its deep brown hue naturally evolves into an elegant silver-grey patina, ideal for high-end decks, facades, and outdoor landscaping.

Natural Accoya, the benchmark for performance and stability

Natural Accoya® is an acetylated solid wood offering exceptional dimensional stability and Class 1 durability. Thanks to its patented process without the addition of toxic substances, it durably resists moisture, insects, and rot while retaining the authentic appearance of natural wood. Its excellent long-term performance makes it an ideal solution for the most demanding decks, facades, and outdoor landscaping.

Accoya Color Grey, the elegance of durable grey

Accoya® Color Grey combines the exceptional performance of Accoya with a grey hue integrated throughout the wood's thickness. Mass-colored using a non-toxic process, it maintains a homogeneous appearance over time, without flaking or regular maintenance. Its dimensional stability and Class 1 durability make it an ideal solution for contemporary decks and facades.

Imbue™, the heat-treated radiata pine for decking

Imbue™ is distinguished by its characteristic dark brown hue and its clean, regular flat-sawn grain, typical of plantation radiata pine. A patented heat treatment at over 230°C, without any chemicals, profoundly transforms this fast-growing wood: it resists fungi, termites, and weathering, while gaining remarkable dimensional stability. An ecological and high-performance alternative to exotic woods.

Generations of expertise dedicated to wood

RDK stands out for its sharp technical expertise, the fruit of in-depth knowledge of all wood species and their specificities. The company guarantees consistent quality through strict manufacturing tolerances, ensuring homogeneous boards batch after batch. Originating from the construction world, it also holds a global vision of the sector, allowing it to understand its clients’ on-site constraints. Its flexibility and responsiveness enable it to adapt its production to the specific needs of each partner. Finally, its family roots make it a solid, human-sized company, committed for the long term.

A trusted partner

The Grad® invisible fastening system can only reveal its full aesthetic and technical potential if the accompanying wood meets very strict precision requirements. This is precisely what we find at RDK: rigorous wood shaping, consistent sections, and a true attention to detail that facilitate installation and guarantee perfect alignment of the boards: one of our absolute priorities. Beyond product quality, it is a common vision of the profession that brings us closer: RDK, like Grad®, thinks beyond its own link in the chain, anticipating the needs of the installer and the end-user. This mutual understanding of each other’s challenges makes RDK a natural partner for Grad®.
