To Build Decks That Last.

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 battens, galvanised lip channels and structural pine. The decking accessories we supply make installing various materials easier and more efficient for contactors, as well as more appealing for the property owner.

Sub-Structure Materials

Make Plans Before Jumping Into Your Decking Project

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 materials include structural CCA treated pine, composite battens, adjustable pedestals, galvanised steel to name but a few.

Using the incorrect screws could impact you on maintenance such as corrosion and snapping of the screws or lifting of the decking boards.
