100x100mm 2.4m Sawn & Treated C24 Graded Reg'd/KD Softwood

About

This 100x100mm 2.4m 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. At 2.4m, it can be a convenient stock length for smaller framing jobs, repairs and cut-to-size components.

Typical applications include square-section uprights, support posts, braced framing and substantial timber subframes. For outdoor posts or pergola supports, confirm both the structural design and the correct preservative Use Class before choosing a timber. Colour alone does not establish ground-contact suitability. These are examples of uses to consider, not a guarantee of suitability for every load or exposure condition.

The nominal section is 100x100mm; the current catalogue lists an approximate finished section of 95mm x 95mm. 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.

Can this section be used as a structural post? Possibly where specified by a competent design, but C24 grading alone does not establish post capacity, bracing or appropriate outdoor treatment. Support conditions, stability and the full structural arrangement must be assessed.

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 2.4m 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.
