Structural material is a very important factor to consider when building a deck. Your deck is only as strong as the sub-structure it is built on. On The Deck has a range of structural materials including wood composite batten, Buzon pedestals and structural pine.

Many factors need to be considered when making the choice between substructure materials, for example the ground conditions that it will be built on top of, height above ground level, waterproofing concerns, what decking product you choose and environmental conditions.

Structural pine should always be CCA treated as well as H3 rated when building a deck or using it for an outdoor application. The H3 rated pine is suitable for outdoor uses and above ground applications. It is also resistant to termites. Should your application need to have in ground or water contact, the Hazard Rating should be increased accordingly.

  • Dimensions: 38 x 38mm

  • Gauge: 2mm

  • Length: 6m

  • Weight per Length: 5.1kg

  • Weight per Meter: 0.85kg
