Description

Ensure your balustrade stair installation is secure, stylish, and long-lasting with the Composite Stair Railing Post from NeoTimber®. Designed for use at stair bottoms or mid-stair points, this post system offers exceptional support and an elegant finish for any staircase.

Each Stair Railing Post includes a robust steel insert for internal strength and a premium capped composite sleeve for a polished look. The set also comes with a black aluminium post cap and skirt, delivering a refined finish that matches the rest of the NeoTimber® balustrade system. This product includes the post set only, rails are sold separately.

Pre-cut for stair applications, the Post installs easily into timber decking or concrete. The post includes all required fixings, making it a complete and convenient solution for stairway sections. It’s designed specifically for stair angles, not flat or level surfaces - see our Straight Railing Post for flat installations.

Colour-matched to NeoTimber® decking, the capped composite sleeve is resistant to fading, splintering, and weathering. Tested to BS 6180:2011 standards, the Stair Railing Post ensures safety and structural reliability in residential and select commercial settings.

Sustainability is central to how we manufacture our composite products. The wood content in our Composite Balustrade Stair Railing Post is FSC® 100% certified, ensuring it is sourced from responsibly managed forests. In addition, our composite systems incorporate recycled aluminium, steel, and plastics, helping to minimise waste, reduce reliance on virgin materials, and lower overall environmental impact.

Enhance your stair system with added strength, style, and long-lasting performance using this essential component, designed to deliver both reliable support and a refined finish.
