LOSP Gateboard is H3 treated and primed for external use. These timber boards have been machined with a tongue and groove profile on the edges, allowing them to fit together snugly when installed. This profile creates a tight joint between the boards with a V-joint detail to create interest. Gateboard is suitable for internal and external use, and is often used for gates and fencing.
