About our 100mm Decking Joist

Our top of the range 100 x 47 Tanalised Decking Joist is perfect for constructing a sturdy decking frame that will stand the test of time also.  Furthermore, it also comes pressure-treated with TANALITH E, adding in equally important rot and fungi protection.

If you need some help with your decking project, check out our Garden Decking Construction Guide.

Our joists are treated with TANALITH E for lasting protection against fungi, insects, and termites. They’re suitable for ground and non-ground contact, indoors and outdoors. Initially green, the timber weathers to a warm brown and then a silver-grey with exposure, without losing any protective qualities.

Log Selection For Joists

Careful selection of natural resources ensures a quality Decking Joist. We also hand-pick raw materials to meet specific component needs, in addition to using the best part of the log. In the ‘green mill,’ we cut logs into rectangular shapes, however, this can cause rough edges. If needed, we further season the timber by drying it, and then also machine it for smooth or shaped surfaces.
