Outdoor Decking Balustrades

Outdoor decking balustrades create a protective barrier around raised decking while helping frame the edge of the deck itself. Our decking balustrade range includes handrails, baserails, spindles and newel posts that fit together to form a complete railing system around your decking.

Whether you're installing a railing system on a new structure or adding one to an existing garden deck, our garden balustrades are available in a range of timber profiles, including square, chamfered and turned spindle styles.

Timber Decking Balustrades for Garden Projects

Decking balustrades are typically built using matching rails, posts and spindles that form the railing around the outer edge of a deck. Choosing components designed to work as part of the same system helps keep installation straightforward and allows each section of railing to follow the layout of the deck.

Timber balustrades remain a popular option for garden decking because they complement outdoor structures and can be finished to suit the surrounding space. The timber can be painted, stained or treated depending on the look you want to achieve, allowing the railing to match fencing, pergolas or other garden features.

Different spindle profiles also allow you to control the overall style of the railing. Square designs create a simple and understated finish, while chamfered edges or turned spindle styles introduce more detail along the balustrade.

Because decks are rarely identical in size or shape, timber components can be cut and adjusted during installation. This allows the railing to run cleanly along straight sections while also following corners, steps or changes in direction around the deck.

Garden Balustrades FAQs

What height should a garden balustrade be?

Decking balustrades for domestic gardens are usually installed at a minimum of 900mm. The exact height often depends on how high the deck sits above ground and the layout of the surrounding area. Raised decks typically use taller railings to provide additional protection along the edge of the structure.

How far apart should decking spindles be?

Decking spindles should be spaced so that a 100mm sphere cannot pass through the gap between them. The 100mm rule is widely used across UK building regulations for staircases, balconies and raised decking to reduce the risk of children passing through the balustrade.

Can timber balustrades be painted or stained?

Items in our outdoor decking range are treated for outdoor use, however we still recommend using a good quality preservative to extend its life. Other pine stairparts may be suitable for outdoor use with an appropriate protective finish. Paint provides solid colour coverage, while stains and oils allow the natural grain of the timber to remain visible. Applying an exterior finish also helps protect the wood from moisture and weather exposure.

Can decking rails and spindles be cut during installation?

Timber rails and spindles can be cut to size during installation to suit the exact dimensions of the deck. Adjusting the components on site allows the railing sections to fit neatly between posts and follow the layout of the structure, including corners, steps or changes in direction.

Can a balustrade be added to an existing deck?

Yes, this is possible, provided the deck structure is strong enough to support the posts and railing sections. Posts are usually secured into the deck frame to create a solid base before the rails and spindles are installed.

Do decking balustrade components need to match?

Decking balustrade components are designed to work as part of the same system. Handrails, baserails and spindles within the same range are sized to align correctly, allowing the spindles to sit neatly together once assembled.
