47x150mm 6.6m Sawn & Green Treated C24 Graded Softwood

About

This 47x150mm 6.6m green-treated C24 softwood is listed as regularised construction timber for UK building and carpentry projects. The specified planed faces and rounded or eased edges make it practical for setting out structural carcassing. The 6.6m stock length is particularly useful when a project calls for longer continuous pieces or a cutting plan with fewer joints.

At 6.6m, this product is an extra-long timber length in the C24 construction range. Long-length timber can be useful when a design calls for continuous pieces or more flexibility when cutting to size, but stock length is not a certified unsupported span. Before ordering, check delivery vehicle access, unloading arrangements and safe handling of the full length.

Typical applications include domestic floor joists, roof rafters, ceiling framing and timber stud or trimmer assemblies. This section is commonly considered for joist layouts, but its suitability depends on a checked design. These are examples of uses to consider, not a guarantee of suitability for every load or exposure condition.

The nominal section is 47x150mm; the current catalogue lists an approximate finished section of 45mm x 145mm. 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. Regularised timber offers a more consistent section than rough-sawn stock, but natural grain, knots and some movement are normal timber characteristics.

Does a 6.6m timber length mean it can span 6.6m without support? No. The supplied length and the allowable clear span are different things. C24 is a strength class under BS EN 338; suitable spans require the loading, joist centres, support, deflection and fixing details to be checked against the applicable design or span tables.

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.

Before ordering 6.6m timber, check delivery access, turning space, safe offloading and how the length will be supported during handling. Store it on level bearers clear of the ground and protect it from prolonged wetting. Ask Simply Timber to confirm availability, finished dimensions, treatment and delivery arrangements in England before purchase.
