Posts of minimum size 115x115 are preferred, even though in many applications, 90x90 would be structurally suitable. This gives the structure a more robust appearance. We embed our posts into the footing and apply a termite & waterproof coating to the embedded section. Embedding the posts into deep footings does away with the requirement for cross-bracing, provided certain criteria are met.
We use pre-primed finger-jointed, laminated, H3 LOSP treated pine posts for most of our balcony, verandah, pergola, carport & gazebo projects. These are expensive, but the best performing posts available. Defects under long term performance such as twisting, bowing or splitting are minimal, if any. The smooth finish is ideal for painting.
If posts are to be stained for a natural timber colour, to say match a deck, remanufactured merbau posts are a good choice, provided the in-ground section is suitably treated.
For framing requiring a painted finish, we use pre-primed finger-jointed, laminated H3 LOSP treated pine. This enables greater accuracy in work, compared with the commonly used laser-cut treated pine. Its smooth, pre-primed finish provides for a superior end finish.
For framing that is to be stained a natural timber colour, we mostly use Monterey Cypress (cupressus macrocarpa) a timber sourced from redundant farm trees. This timber is superior to the common cypress pine (callitris glaucophylla) used as framing.
Other options, where superior finish & performance are required, are available such as laminated kiln-dried cypress pine or merbau.
We will never use proprietary fixing brackets (such as joist hangers) in our verandahs or pergolas.
