Structural Finger Jointing
We take regular stress graded carcassing timber and cut into lengths between 1.8m and 3.0m then re-join. In order to prove that the joint is structurally sound, we use our calibrated test rig in Methven in accordance with CATG accredited factory process controls. The joint itself can be 2-3 times stronger than the original timber, and being cut into shorter lengths prior to joining helps to eliminate bow and twist which is always a problem in longer lengths.
We can supply structural graded finger jointed timber in any sections up to 75mm x 275mm and in grades from C16 up to C30 ex-stock. Our production line can cut any length up to 12m and we can also precision end trim +/- 2mm any length required e.g. 9.135m. Finger jointing removes waste incurred by cutting down standard lengths to non-standard and thus reduces cost, labour, waste and disposal on site.
Non-Structural Finger Jointing
For non-structural applications such as external or internal cladding, finger jointing allows us to price large cladding or decking projects in a fixed lump sum instead of per m2 plus 10-15% for waste. For the first time our clients can specify any length they wish for their projects without including a waste factor for standard available stock lengths. This can be up to 20% depending on landed stock available at any given time which, with hardwood or clear softwood projects with fire retardants, can amount to a significant saving. We are currently producing finger jointed cladding in Scottish Larch, Cedar, Siberian Larch, Douglas Fir, English Oak and Sweet Chestnut.
Finger Jointing benefits
- Finger jointed timber is stronger than conventional dimension timber of the same grade.
- Each piece is straight as defects such as bow, twist and cup are significantly reduced or even eliminated.
- Finger jointing permits the homebuilder to specify continuous long length floor joists that can “double span” i.e. carry the load over supporting walls for the width or length of the project without a break. This improves the stiffness and thus performance of the floor which would not be possible with conventional sawn lumber.
- Most importantly, finger jointing allows us to provide an incredibly consistent product which has been defect cut, pre-straightened, and produced to exact length, strength and aesthetic specifications.
