38x88mm 4.2m Sawn & Treated Softwood

About

This 38x88mm 4.2m green-treated sawn softwood is a versatile board or section for general building, garden and repair projects. It is listed with a rough-sawn surface and square edges rather than a smooth planed finish.

Typical applications include non-loadbearing studwork, utility framing, shed components, bracing and general timber supports. For floor, roof or other load-bearing members, request a suitable certified structural grade instead. These are potential non-load-bearing uses, subject to fixing details and the intended exposure.

The nominal section is 38x88mm; the current catalogue lists an approximate finished section of 38mm x 88mm. Nominal sizes and actual machined dimensions are not always the same. Different mills can have different tolerances, so check the confirmed supplied size before ordering close-fitting joist hangers, brackets or matched timber. The specified rough-sawn faces have a more textured appearance than planed carcassing and may require additional preparation for visible work.

Is this the same as strength-graded C24 carcassing? No. This listing does not declare a structural strength grade, so it should not replace graded joists, rafters or posts without suitable verification and design.

What does green-treated mean? It identifies the listed preservative treatment or appearance, not a guaranteed Use Class. An exposed external application, particularly ground contact or exterior structural support, can require Use Class 4 treatment. Confirm the treatment specification for your intended exposure. Protect freshly cut ends, notches and large drilled holes with a suitable end-grain preservative, and select fixings compatible with treated timber and the environment.

For quantity planning, divide the total running metres needed by 4.2m per piece, round up to whole lengths and allow for cutting waste. Store pieces off the ground on level supports, with suitable weather protection. Ask Simply Timber about availability and delivery across England if your project requires a particular mill specification.
