Key
*joists are the main support base rails that make up the underlying framework of a deck. A spacing of 450-600mm would be the spacing suggested to suit most deck boards, again depending on the deck board. It would be suggested that you test the spacing by laying some boards down and standing on them. If the boards bow allot then you know the spacing is too much, do this before you screw the boards down, just in case you need to then adjust the frame work.
**noggins are a small joist placed between joists as extra support under the boards and for the framework itself. The spacing’s used between the noggins are usually based on the board that is being used. A spacing of 450-600mm would be the spacing suggested to suit most deck boards, again depending on the deck board.
***support beams are beams that are attached to the upright posts, and can be used to support the joists.
