38mm x 250mm - PSE Whitewood

38mm x 250mm PSE Whitewood is a heavy-duty planed softwood section suitable for door linings, stair strings, and a wide range of internal joinery applications where additional thickness and strength are required. Manufactured from selected whitewood and planed on all four sides, this timber provides clean edges, consistent sizing, and a smooth finish ready for installation or decoration.

Supplied at a 38mm nominal thickness and machined down to approximately 33mm finished thickness, this PSE whitewood offers improved rigidity and stability compared to thinner sections. This makes it particularly well suited for use in stair strings, wider door linings, and structural interior joinery where strength and accuracy are essential.

Common uses include internal door linings for thicker wall constructions, staircases and stair strings, boxing-in, casings, and bespoke interior joinery. Whitewood is easy to cut, machine, and fix, making it suitable for professional joiners and confident DIY users.

Supplied untreated, this timber is ready to be painted, stained, or varnished to suit your interior finish. Intended for internal use only or protected environments.
