We carry a wide range of square sawn posts at Southern Timber to cover many potential constructional needs. Large section sawn posts, Permaposts and planed posts, are described elsewhere on the website. Sawn tanalised posts are useful for many fencing, decking and structural applications. This page focuses on the popular 75mm and 100mm posts
The 75mm x 75mm posts are ideal for supporting trellis, panels and fences in sheltered positions or where the panels do not offer too much wind resistance. However, for solid panles and windy areas a 100mm x 100mm post would be preferable. They are also useful as supports for smaller sheds and for cutting into smaller lengths for retainers and supports in raised beds.
75mm x 75mm, tanalised at 1.8 metres (approx. 6')
75mm x 75mm, tanalised at 2.4 metres (approx. 8')
75mm x 75mm, tanalised at 3.0 metres (approx. 10')
Post and rail fences and agricultural fences normally utilise the 75mm x 125mm posts which provide a larger face to secure horizontal rails to. Also available is the 75mm x 150mm post which is often specified in the fences adjoining dual carriageways and country roads.
75mm x 125mm, tanalised at 1.8 metres (approx. 6')
75mm x 125mm, tanalised at 2.13 metres (approx. 7')
75mm x 150mm, tanalised at 2.13 metres (approx. 7')
Featheredge fences and privacy fence panels generally offer more resistance in strong winds and are best supported by the more substantial 100mm x 100mm. These posts are also sometimes cut into shorter lengths to create dwarf posts up to joist level in some elevated decking installations.
100mm x 100mm, tanalised at 1.8 metres (approx. 6')
100mm x 100mm, tanalised at 2.4 metres (approx. 8')
100mm x 100mm, tanalised at 3.0 metres (approx. 10')
100mm x 100mm, tanalised at 3.6 metres (approx. 12')
100mm x 100mm, tanalised at 4.8 metres (approx. 16')
Finally, all of our posts are pressure treated, most of them with Tanalith E preservative. This treatment gives the timber a light green tint which soon mellows to pale brown then grey. The most important factor is the protection against fungal and insect attack.
