Calibrated QF3 Grade Square Edged Oak (per cubic foot) 23mm

Calibrated French Oak QF3 timber is a characterful grade with open knots up to 40mm in diameter with some small splits and checks. The boards are kiln dried to 9-11% moisture content and carefully stored in our heated and acclimatised factory.

The QF3 grade quality adheres to the following criteria:

"Three knots less than 40mm are permitted in pieces with a width less than 120mm and one extra knot for every additional 40mm in width in case of wider pieces. Tolerance for one dead or unsound knot less than 20mm and wane less than 3mm. Excluded: bark pocket, brown pith, rot holes, boxed heart or exposed pith, included sapwood."

Please note: Calibrated is not the same as planed all round, it is fast pre-plane to bring the timber to a regular size and allows an extra 4mm in thickness for final planing and straightening.
