The decking timbers are 95mm wide which means that for every meter in width you will need approx. 10 decking timbers. Alternatively it is three decking timbers to every foot width. Joists or supporting timbers underneath form the framework and they should be placed at 400mm intervals to support the floor.
Example: 3.6m x 3.6m deck laid over existing patio or concrete area
Framework: 4 no. 3.6mts 150mm x 35mm or 100mm x 35mm (depending on height off ground)
Floor joists: 9 no. 3.6mts 150mm x 35mm or 100mm x 35mm
Decking Timbers: 38 no. 3.6mts 95mm x 35mm
4 boxes 4mm x 60mm Screws
If you are laying the deck on grass you will need to sink posts into the ground to act as a base.
