Sawn Graded Timber

Softwood Building Timber - Rough Sawn or Regularised - Graded Carcassing Timber:

This timber is high quality Home-grown or European whitewood, some now being regularised Easi-edge - (semi-planed with eased corners),­ kiln-dried and graded to SSC16 or SSC24 cer­ti­fica­ti­on, so suitable as joists, rafters and building timber, and is generally Grade-Stamped for inspection by your Building Inspector.

Normal lengths are 3.0, 3.6, 4.2 & 4.8 metres, and 5.4 & 6.0 metres in some of the larger purlin sizes; We can also source larger sizes (which may not be kiln-dried), and longer lengths to order.

Smaller timber sizes are generally kiln-dried, larger timber sizes can be unseasoned or air-dried;
Most 50mm & 75mm thicknesses of graded-carcassing timber are kiln-dried; 100mm and thicker sizes take a long time to kiln dry, and generally are offered unseasoned, and air dry "in the stick".

Unseasoned timber can have a moisture content approaching the maximum saturation level of 27%, when air-dried "in-stick" this can fall to 20-23%, and if kiln-dried the moisture level is brought down to 18-20%. Generally in a heated building, the moisture level can be 8-10%, and it is here, where the moisture level of timber is rapidly changed, that twisting, warping and splitting can occur.

We keep tilt-fillet in stock and can cut firring pieces and other timber sections to size for flat-roof or pitch-roofing work.

Carcassing Timber is a natural product - variations in knots, colour, grain and surface-checking should be expected.


Price is generally per running metre or per length - we can price larger quantities and pack lots per cubic metre.
