Deck Posts & Rails

Deck posts and rails provide the essential framework for safe, attractive decking balustrades. These structural components define the perimeter of raised decks, create boundaries for steps, and add architectural interest to outdoor living spaces. Choosing quality posts and rails ensures your decking meets building regulations while enhancing the overall appearance of your garden.

Our Range of Balustrade Posts and Railings

McMahons stocks a comprehensive selection of balustrade components to suit timber, composite, and contemporary deck designs.

• Pressure-treated D-rail timbers for creating robust horizontal frameworks that support balustrades and handrails on raised decks.
• Treated softwood newel posts available in various heights, ready for painting or staining to match deck boards and garden features.
• Composite balustrade systems providing low-maintenance performance with consistent colour and no risk of splintering over time.
• Base plates and post anchors for secure fixing to deck frames, concrete or block walls without compromising structural integrity.

Consider the height requirements for your project—standard balustrade heights of 900mm suit most residential decks, while raised platforms may require 1100mm. Factor in the spacing between spindles to comply with building regulations, particularly if young children will use the space.
