The aluminium balustrade post is the upright that carries your rails — a 75mm × 75mm square post in alloy 6005, finished in matt black powder-coat (RAL 9017) so it won't rust, rot or fade outdoors. Each post stands 1140mm to the top of the cap and weighs around 5kg.
Every post has a 120mm square base plate with a fixing hole in each corner, so it bolts down onto any solid structural surface — timber decking, concrete, stone or masonry. M10 × 80mm bolts are our recommendation, though the right fixing depends on what you're fixing into, and ground and wall fixings aren't supplied. A matching base cover finishes the foot neatly.
The post is supplied undrilled, so bracket heights can be set to suit the run, and two alignment stencils come with each post to mark the bracket positions square and level. Posts are spaced up to a maximum of 1829mm apart, with additional posts added along longer runs to keep the balustrade rigid.
Posts are sold singly, so you buy exactly the number your layout needs. If you'd rather not count them yourself, the Build Your Own aluminium balustrade kit works out every post, rail and bracket from your measurements and adds them to your basket in one go.

Yes. They're powder-coated aluminium, so they're rust-resistant, UV-stable and built for year-round outdoor exposure in UK conditions. Rinse down twice a year with warm soapy water, check and re-tighten screws occasionally, and in coastal areas rinse monthly to remove salt build-up. Avoid pressure washers and harsh chemicals.
The maximum spacing between posts is 1829mm (6ft) clear between post faces. This is the longest span your aluminium rail is designed to support, so runs longer than that need additional posts along them.
You can space posts closer together than the maximum, and cut the rails down to suit — always cut equal amounts from both ends so the picket spacing stays balanced.
Each post is 75mm × 75mm square, with a finished height of 1140mm to the top of the post cap. This gives a finished guarding height of 1100mm once installed, in line with UK building regulations. Each post has a 120mm square base plate with a fixing hole in each corner for secure mounting.
Yes — posts are sold separately. The rail kit contains the rails, pickets, spacers, brackets and fixings, but not the posts, so you buy exactly the number of posts your layout needs. Our balustrade calculator works out how many posts you need for your run.
The maximum span between posts is 1829mm. For any run longer than this, you'll need additional posts along the run to stay within that maximum and keep the balustrade rigid and compliant.
Each post has a 120mm square base plate with a fixing hole in each corner. Posts are bolted down onto a solid structural surface — recommended fixings are M10 × 80mm bolts, though the correct fixing can vary depending on your mounting surface. A base cover finishes the fixing neatly.
Posts can be fixed to any solid, structural surface — decking (into the joists), concrete, stone, or masonry with suitable fixings. The key is that the post fixes into solid structural material beneath the surface, not just a decorative top layer.
The posts are made from powder-coated aluminium in a black finish — rust-free, low-maintenance, and built to handle UK weather year-round without the upkeep of timber or steel.

Our aluminium balustrade has been load tested to the domestic (Category A) barrier loads in BS 6180:2011 and PD 6688-1-1, for decking, patios, steps and stairs.
Yes. It has been load tested to the domestic (Category A) barrier loads in BS 6180:2011 and PD 6688-1-1, on level runs and 35° stairs at the full 1,829 mm span. It passed the 0.36 kN/m line load at the top of the barrier, the 0.5 kN/m² infill load and the 0.25 kN point load, all within the 25 mm deflection limit, and its ultimate failure load was more than 9 times the domestic design load. The full load test report (TOL-LTS-001) is available to download (PDF).
Domestic decking, patios, steps and stairs. Whether a particular installation complies also depends on it being assembled correctly and fixed to a suitable structural surface.
The finished guarding height is 1100 mm, and pickets are spaced at 96.5 mm so a 100 mm sphere cannot pass through.
Yes. The aluminium will not rust, and the powder coating passed 1,000 hours of neutral salt spray testing (ASTM B117). In coastal areas, rinse it down roughly once a month to remove salt build-up.
The maximum clear span is 1,829 mm, measured between post faces rather than post centres. Runs longer than that need additional posts along them.
For domestic decking, patios, steps and stairs. The full load test report (TOL-LTS-001) is available to download. As with any balustrade, the finished installation also depends on correct assembly and fixing to a suitable structural surface.
