Unsorted redwood timber in a 75mm x 225mm section is a high-grade Scandinavian softwood ideal for heavy joinery components. Milled from slow-grown redwood, it offers straight grain, low knot content, and clean machining properties that suit both trade and bespoke interior work.

Specifications

What it's used for

• Stair strings and newel post blanks where a deep, stable section is required
• Door frames and linings requiring a reliable, knot-free face after machining
• Window boards and sill sections where a clean planed finish is essential
• Bespoke interior joinery components worked to tight tolerances

Fitting and handling

Store the timber flat, off the ground, and under cover before use, allowing it to acclimatise to the ambient conditions of the building for at least 48 to 72 hours to minimise movement after fitting. When fixing, use appropriate structural screws or nails for the section size, and pre-drill near ends to avoid splitting the grain. For an exposed face finish, plane or sand with the grain and apply a suitable primer or sealer promptly to protect against moisture ingress.

FAQ

What does unsorted grade mean for redwood timber?

Unsorted is the highest commercial joinery grade of Scandinavian redwood. At the mill, boards with significant knots, shakes, or defects are removed, leaving a consistent run of timber with low knot content and straight grain. It is not the same as a construction grade such as C16 or C24.

Is this 75mm x 225mm redwood sold rough sawn or planed?

This section is supplied sawn. The 75mm x 225mm dimensions are nominal, meaning the finished size after planing will be slightly smaller. If you require precise finished dimensions, allow for machining loss when ordering.

Can unsorted redwood be used for external joinery?

Unsorted redwood is primarily suited to interior joinery. For external applications it would need thorough priming and painting on all faces and edges, including end grain, before installation. Where long-term external exposure is a concern, a treated or more durable species is generally a better choice.
