Timber poles must comply with the requirements of SANS 457-2 or SANS 457-3, as relevant. Laths and battens must comply with the requirements of SANS 1288, 1707-2 (eucalyptus), or SANS 1783-4 (pine), as relevant. All timber should be preservative treated in accordance with the requirements of SANS 10005.

Poles for use as structural elements shall have a diameter of at least 100 mm measured at thin ends. PLANTING POSTS

The science of treating timber properly provides for the preservative to be deeply impregnated into the sapwood thereby giving a deep envelope of treatment around the central heartwood. All poles must be CCA treated and meet the SABS 457 Specification for Eucalyptus and Pine wood. Strict attention is given to SABS 0163:1994 Sections 1 and 2, Table 5 dealing with tensions for round poles.
Besides the quality requirements of Code 457, the poles must also meet aesthetic requirements, namely no excessive cracks or crookedness, and they must be clean.
LATHS
Laths must also meet the SABS 457 Specification and must be of the Eucalyptus species and must be reasonably straight.
