Decking Board Selection

Figure 3: Common decking profiles

Decking is available in Cypress and a range of hardwood species.

Deck profiles include: square edged (plain), pencil round edges (arrised) and reeded faced (ribbed). Pencil round provides a soft appearance compared to square edged, and there is less likelihood of splintering at edges. Reeded facing is employed where increased slip resistance is desired, however if this feature is unwanted, the reeded face can be laid downward to prevent dirt potentially catching in the ribs.

Boards are sized to minimise the likelihood of cupping and twisting while still allowing easy water run-off. Popular sizes along with species and nailing requirements are provided in Table 3.
