The Story
PSE whitewood deep machined timber in a 32mm x 275mm nominal section, finishing at a true 27mm x 265mm, is a wide planed board suited to stair strings, door linings, window reveals, and internal joinery where a broad, accurate face is essential.
Specifications
| Material | Whitewood (European Spruce) |
| Finish | Planed Square Edge (PSE) - all four sides |
| Nominal Size | 32mm x 275mm |
| Finished Size | 27mm x 265mm |
| Profile | Square edge, deep machined |
| Use Class | Internal (UC1/UC2) |
What it's used for
- Stair strings - the wide finished face and consistent thickness make it well suited to cut or closed-string staircase construction
- Door linings and frames - the 265mm face width accommodates thicker wall constructions common in renovation and older UK housing stock
- Window reveals and internal sill boards - the flat, smooth faces fit directly without additional planing
- General internal joinery where a deep, accurately sized section is needed and a clean surface finish is required from the outset
Fitting and handling
Store this section flat, off the ground, and in a dry, ventilated space before installation. Allow the timber to acclimatise inside the building for at least 48 hours prior to fixing, particularly in centrally heated properties, to reduce the risk of movement after fitting. Fix with appropriate screws or nails for the substrate and apply a suitable primer, paint, or wood finishing product if the timber will be exposed to humidity, such as in a stairwell or near an external door.
FAQ
What is the actual finished size of this section?
The nominal size is 32mm x 275mm, but after machining the finished size is 27mm x 265mm. This is the measurement to use when planning your project or ordering in relation to wall thickness or stair construction.
Can this section be used for stair strings?
Yes. The 265mm finished face width and 27mm thickness make this a commonly used section for stair strings in domestic staircases. Always verify the required string depth against your stair design before ordering.
Is whitewood PSE suitable for painting or staining?
Whitewood PSE takes paint and primer well and is widely used for painted internal joinery. If you intend to stain or apply a clear finish, be aware that whitewood has a relatively pale, even grain that can show knots. Seal knots with an appropriate knotting solution before priming.
