Posts - square 125mm +

At Southern Timber we carry a range of larger cross section posts up to 4.8 metres (16’) in stock. We can get larger cross sections and lengths to order. Smaller section sawn posts, and planed posts, are described elsewhere on the website.

Both the 125mm and 150mm posts can be sued for carrying pedestrian and medium field gates, the longer lengths have been purchased for a wide variety of projects including pedestrian bridges, a 3.0 metre high featheredge fence (in a very isolated location), tree houses, balconies and for large retaining posts..

Our 175mm x 175mm and 200mm x 200mm posts have always been used as gate posts but we have been increasingly asked for longer lengths of these posts. The 200mm x 200mm posts are stocked at 3.6 metres and 4.8 metres and some of the local timber merchants and civil engineers purchase these from us

All of our posts are pressure treated and our standard products are pressure treated with Tanalith E preservative. This treatment gives the timber a light green tint which soon mellows to pale brown then grey, but most importantly provides protection against fungal and insect attack.

We also carry a number of larger section planed redwood posts. These are available in 125mm x 125mm at 2.4 metres and 4.8 metres plus 150mm x 150mm posts in the same lengths. These are ideal for elevated decks, first floor balconies and other projects where large posts with a planed finish are required.
