Enhance Composite Decking with a Black Aluminium Handrail for Stairs
Deck stairs need a handrail that is safe to hold and looks right next to your boards. A black powder-coated aluminium balustrade does both: it guards the open side of the steps, gives a firm rail to grip and suits the clean lines of composite decking.
Why choose a black aluminium handrail?
A modern look for composite decking
Matt black contrasts crisply with lighter boards such as Mist Grey and Aged Oak, and blends with darker boards such as Midnight Black.
It suits:
- Garden decking
- Holiday lodges and static caravans
- Steps up to a balcony or raised deck
- Hot tub platforms
- Multi-level decks

Durable and low maintenance
Our aluminium balustrade is finished in black powder coat (RAL 9017) and salt spray tested for 1,000 hours. Unlike timber or mild steel, it will not rot, warp or rust, and it never needs painting.
Safer deck stairs
The system is load tested to the domestic (Category A) barrier loads in BS 6180:2011 and PD 6688-1-1, and finishes at 1100mm to the top of the rail. Pickets sit at 96.5mm centres, so a 100mm sphere cannot pass through. On stairs it gives:
- A secure, comfortable rail to hold
- A guarded edge on the open side of the steps
- Confidence for children, older visitors and guests
Simple, modular installation
The system comes as a flat-packed kit for a competent DIYer or a professional installer.
- Posts surface fixed through a 120mm base plate
- A stair bracket kit sets the rails to the pitch of your steps on site
- Rails cut to suit on site
- A matching gate if you need one at the top of the steps
Posts must fix into the deck's structural frame, not just the boards. Fixing bolts are not included.

Made for composite decking
Composite decking gives you a natural grain and a slip-resistant surface, and a black aluminium handrail adds the structure and modern style. Together they make a low-maintenance deck that looks good all year.

Steps beside a wall?
If your deck steps run alongside a wall, a wall-fixed rail may be all you need. See our stainless steel handrails, including a wall-mounted handrail kit in satin or black.
