Finger Jointed S4S Timber - Longer Lengths Reduce Wastage

   Its Advantages

1. Availability of totally defect-free timber
2. Better quality & strength of joints as compared to on-site joining
3. Overall reduction in costs-on-site jointing %construction labour costs.
4. "Cut to Size" convenience.
5. Freedom for design with long length options upto 20'.

Finger Jointing is a modified butt joint where shear force is made to transmit compression or tension in wood member. The fingers are usually cut at a fiber slope of 1:8 & the cut fingers are glued with special resins & then interlocked with pressure to produce longer lengths.

To achieve high strength, normally the glue area is designed to have around 6 times the cross-section area of the timber.

The timber for jointing are kiln dried to maintain proper moisture content. The joint could be oriented with the finger designs visible at the timber edge or on the flat side. From the point of view of strength, both these considerations are the same.

Finger Jointed S4S Timber can be used as :

Door & Windows frames,partition & false ceiling framework, furniture,beams & purlings (either with or without lamination).
