Among the oldest and most commonly used construction materials, wood is one of the world's most plentiful and economical building resources. Pressure treatment, with a variety of preservatives, is extensively used in industrial applications, which often subjects the wood to harsh environmental conditions. Pressure treatment preserves wood's structural soundness and significantly extends its service life by protecting it from natural predators.

Pressure treated wood has proven to be an ideal material for construction in and around aquatic environments. It is resilient enough to withstand battering by the ocean and ships, yet resistant to the destructive forces of salt water, decay-causing fungi and wood-destroying marine organisms.

Stella-Jones' industrial lumber products include marine pilings and timbers, foundation piling, highway guide rail posts and bridge timbers. Based on the Company's strategic plant locations and diverse selection of wood species and preservatives, Stella-Jones has established a significant market share in Canada.
