4.5m x 145mm x 20mm Planed Square Edge (PSE) Redwood

6x1 PSE Redwood Timber Our 6x1 PSE redwood board is a high‑quality, planed timber ideal for interior construction and joinery projects where strength, appearance, and accuracy matter. Cut from quality redwood and finished with a smooth planed square edge (PSE), this board offers clean lines and consistent dimensions, ready to use straight off the shelf. Measuring 4.5 metres in length with a finished size of 145mm x 20mm, this timber is planed from a larger 150mm x 25mm board to deliver a refined surface and sharp square edges. The untreated finish makes it particularly suitable for indoor environments where timber will not be exposed to moisture or weather conditions. Commonly used for joinery, shelving, boxing-in and general interior building applications, this 6x1 PSE redwood board combines workability with a neat, professional appearance. Redwood is known for its strength-to-weight ratio and ease of cutting, making it a popular choice with both trade professionals and DIY users. Because the timber is untreated, it should not be used externally or in areas exposed to damp. However, this also means it can be easily painted, stained, or sealed to suit your interior project requirements. Key Features of 6x1 PSE 145mm x 20mm (planed from 150mm x 25mm). 4.5 metre lengths.
