Technical Information
Poles
All poles are SABS CCA treated poles. We use both pine and selinga.
Pole specifications and diameter
Columns are a minimum of 125mm - 150mm
Ring beam poles are a minimum of 100mm - 125mm
Trusses are in general 75mm - 100mm up until 4.8m. Poles longer than 4.8m have a minimum diameter of 100mm - 125mm
Our truss spacing is 700mm apart although you can span up to 900mm
Please note that for wider spanning structures, the timber diameter will be as per engineers specifications.
It is extremely important to have the pole sizes for any structure specified in writing as many contractors use inferior poles of incorrect diameter to save on costs. This severely effects the structural integrity of the roof and can have disastrous results.
Laths
Laths are SABS CCA treated and are 200mm - 400mm in diameter
Reed
Only selected quality cape reed (dekriet) is used on our structures
Ridge
Our Ridges are reinforced with wire mesh and consist of a mixture of sand, grit & cement.
