TTT SG8 Timber

To complement our comprehensive range of poles TTT Products sources and supplies timber suitable for use in many situations.  TTT SG8 Timber is  stress-graded timber that has been tested for stiffness, bending, tension, and elasticity by our timber suppliers.  Strength is not able to be tested but there is an accepted correlation between stiffness and strength so it is generally understood that TTT SG8 Timber is stronger than TTT Unverified Retaining Wall Timber.  Visual characteristics such as knots are the main determinant of strength (refer NZTIF) and are taken into account when grading TTT SG8 Timber.

All timber supplied by TTT Products is reliably top quality, and sourced from professional, sustainably managed sawmills. We check all the timber we source to ensure it has been graded by the supplier and is of regular sizing and consistent quality.

TTT SG8 Timber is generally treated to H4 Hazard Class to provide protection against fungal and insect attack in an outside, in-ground, non-critical use situation.  TTT SG8 Timber can also be treated to H5 Hazard Class to provide an increased level of protection in an outside, in-ground, critical use situation.

  • Construction
