When considering materials for your outdoor space, it’s vital to select something that suits your requirements. Composite decking is a very popular choice, due to the fact that it's highly versatile. Composite decking boards are available in lots of different dimensions, colours and aesthetics.

One expression you might have come across if you’ve been researching composite decking options is ‘square edge decking’. What exactly is square edge decking, and what makes it different from other types of composite decking?

Square edge deck boards - also known as ungrooved decking boards - have a smooth, ungrooved edge. This makes them distinct from grooved deck boards, which have a grooved edge for easier installation.


Grooved vs Ungrooved Composite Decking

When it comes to building your new deck, grooved and ungrooved decking products require different installation techniques. Grooved composite decking boards can be fixed in place using fasteners that aren’t visible after installation, whereas square edge decking is usually screwed through the top.

The best kind of decking for your project will depend to some extent on the kind of surface you're installing on, but here at DeckPlus, we generally recommend using grooved decking boards with ungrooved (square edge) boards as trim.

Here's what grooved decking looks like from two different angles, including a view of the visible groove that runs along the edge of the board. As you can see, these grooves aren’t visible after installation.
