4x1 PSE Timber for Carpentry Projects Our 4x1 PSE timber is a high‑quality redwood board that’s been planed all round for a smooth, consistent finish. With square, crisp edges and accurate dimensions, it’s ideal for finishing work where appearance matters just as much as strength. Made from larger 100mm x 25mm boards and precision‑planed down to a finished size of 95mm x 20mm, this timber offers excellent stability and ease of handling. The untreated redwood makes it straightforward to paint, stain, varnish, or treat to suit your project, whether you’re working indoors or preparing it for external use. At 4.5 metres in length, this 4x1 PSE timber is especially useful for longer runs, reducing joints and giving a cleaner overall look. Commonly used in carpentry and joinery, it’s suitable for shelving, boxing in, framing, furniture components, and general finishing applications.
