Sawn timber processing: what buyers should check

Start with the required specification

Distinguish rough stock dimensions from finished sizes. An inquiry should list thickness, width, length, quantity per size and subsequent drying, planing or trimming. Agree machining allowances so the timber remains suitable after finishing.

Material selection and sawing layout

Raw material is assessed for size, grain direction and defects. Cutting layouts help recover usable stock and avoid placing unsuitable knots, cracks or wane in demanding components. The method depends on available equipment and batch requirements.

Ripping, edging and cross-cutting

Ripping, edging and cross-cutting produce stock to a cutting list. Blade condition, alignment and feed influence consistency. A sawn surface is not a finished planed surface; specify finishing requirements separately.

Inspect stock before further processing

Check dimensions, edge squareness, knots, cracks, warping and wane. Agree sampling and measurement positions rather than relying only on a grade name. Where drying is required, specify acceptance sizes after drying or planing.

Information needed for quotation

Send a cutting list, units, quantities, intended use, quality requirements, delivery destination and required date. Minimum quantities and delivery schedules are reviewed per order. Specifications, approved samples and acceptance terms are recorded in the quotation or B2B contract.
