Decking profiles are available in many different patterns, smooth, ribbed, grooved, side clipped, wide, narrow, and thick and thin, explained here.
Both Timber and Composite deck boards are available in a range of sizes from 60mm to 160mm wide and from thicknesses from 19mm to 35mm as standard.
This decking information page is not to show one product better than another but simply to demonstrate the various profiles of deck available.
Always consult the manufacturer for the best practice of construction as they do vary.
The length of the deck board should not be important, why only select only single long lengths for your project – this is not a common practice for interior flooring…
S4S E4E Smooth Decking
Probably the most common decking profile, smooth 4 sides and eased on 4 corners. This decking is referred to as smooth decking.
This decking is commonly known as Ribbed or Reeded; it has eased corners and should be smooth on the other side. This decking was designed to be used with the reeded face to be placed down to facilitate the water drips away from the joist. The ribbed profile can be exceptionally slippery when wet and is difficult to maintain. This form is not advised.
S4S E4E Smooth with side fixing groove.
Similar to standard smooth decking except the addition of a rebated groove to the side of the board to accept a side fixing system. Be sure that this groove matches the height and depth profile of your fixing clip, there are many variables. If in doubt inform your timber supplier of your intended use or ask which fixing clip should be used.
This decking board is called reversible due to it being Ribbed/Reeded on one side and grooved on the other with eased corners. This should only be used with the reeded side facing down and thus not a true reversible board. This profile of decking is difficult to maintain due to the deep grooves. Due to the reduced surface area grooved decking provides less physical traction than a smooth surface and should be avoided.
This is also a known as a reversible decking board, smooth on one side and Grooved on the other, the amount of grooves depend on the board width. It should in all instances be installed grooved side down.
This was the first side fixed decking profile, created in 1984, smooth finish and eased upper corners
Patented in 1992, the first and only invisible deck fixing clip system available.
Grooved with Anti-Slip
This decking is available from many manufacturers with various patterns, some of which have anti slip strips added to the deck board to enhance the anti-slip properties. There are variants to this style of board, falling over and using your hands as protection can lead to serious abrasions. Falling over on a smooth deck is much less likely to cause an abrasive injury.
