Aluminium Balustrade

Aluminium Balustrade Systems for Decking, Patios & Balconies

Our aluminium balustrade range gives you a modern, rust-free railing system for decking, patios, balconies, terraces and stairs. Every part is black powder-coated aluminium — strong, lightweight and built to handle UK weather all year round with almost no maintenance. Browse the full range below, or build your own complete kit using our calculator.

The easiest way to order is to build your own complete kit. Our aluminium balustrade kit uses a simple calculator — enter your measurements and it works out every post, rail and bracket for your project, then adds the whole kit to your basket in one click. No guesswork and no over-ordering.

Why choose an aluminium balustrade?

Aluminium is one of the best materials for an outdoor balustrade. It won't rust, rot or corrode the way steel or timber can, so a black powder-coated aluminium balustrade keeps its clean finish for years with only occasional cleaning. That makes it ideal for exposed and coastal locations, as well as everyday decking, patios and balconies.

• Rust-free and low-maintenance — the powder-coated finish resists corrosion and won't need painting or treating.
• Strong yet lightweight — easier to handle and install than steel, without sacrificing strength.
• Built for UK weather — holds its finish through rain, frost and sun, year after year.
• Coastal-friendly — naturally corrosion-resistant, ideal for salt-air environments.

Designed for UK homes and building regulations

Our aluminium balustrade system is built around 75mm square posts with a finished guarding height of 1100mm, designed in line with BS 6180:2011 — the British Standard for barriers in and around buildings. Picket spacing is 96.5mm, within the requirement that a 100mm sphere cannot pass through. As full compliance also depends on correct installation for your setting, we'd always recommend confirming the requirements for your project.

Build your own aluminium balustrade kit

Our system is designed to be configured to your project. You choose the posts, rails, brackets and any gates you need, and it adapts to straight runs, corners and stairs. The Build Your Own aluminium balustrade kit makes it simple: the calculator works out exactly how many parts you need for your layout and adds them to your basket in one click.

Frequently Asked Questions

How long do aluminium balustrades last?

Aluminium balustrades are built to last for many years with very little upkeep. Because the aluminium is powder-coated, it won't rust, rot or corrode the way timber or steel can, so it holds its finish and strength through UK weather year after year. With occasional cleaning, you can expect a long service life outdoors.

Are aluminium balustrades suitable for coastal areas?

Yes. Aluminium is naturally corrosion-resistant, and the powder-coated finish adds a further protective layer, making it an excellent choice for coastal and exposed locations where salt air would quickly damage steel or timber. In coastal areas we recommend rinsing the balustrade down roughly once a month to remove salt build-up and keep it looking its best.

Do aluminium balustrades require maintenance?

Very little. Rinse the balustrade down around twice a year with warm, soapy water, check and re-tighten any screws or fixings occasionally, and in coastal areas rinse monthly to remove salt. Avoid pressure washers and harsh chemicals, as these can damage the powder-coated finish. That's all that's needed to keep it looking good and performing well.

Can I install aluminium balustrades myself?

Yes — our aluminium balustrade system is designed to be DIY-friendly. It comes flat-packed and ready to assemble, with stainless steel fixings included, and the rails can be cut down on site to fit. You'll need basic tools and a metal-cutting saw for any trimming. Each post fixes to a solid structural surface. If you'd like help planning your layout, use our balustrade calculator or get in touch with our team.

What colours are available for aluminium balustrades?

Our aluminium balustrade system is supplied in a black powder-coated finish, giving a clean, modern look that suits both contemporary and traditional outdoor spaces. The powder-coated finish is hard-wearing and colour-stable, so it keeps its appearance without fading or needing repainting.

Are aluminium balustrades more expensive than other materials?

Aluminium can have a slightly higher upfront cost than some timber options, but it works out more cost-effective over time. Because it doesn't rust, rot or need repainting, there are no ongoing maintenance or replacement costs — unlike timber, which needs regular treatment, or steel, which can corrode. For a long-lasting, low-maintenance outdoor balustrade, aluminium offers excellent long-term value.

Do aluminium balustrades comply with UK Building Regulations?

Our aluminium balustrade is designed in line with BS 6180:2011, the British Standard for barriers in and around buildings. Installed correctly, it achieves a finished guarding height of 1100mm, with picket spacing of 96.5mm — within the requirement that a 100mm sphere cannot pass through. As full compliance also depends on correct installation for your specific setting, we'd always recommend confirming the requirements for your project and checking with your builder or building control for anything safety-critical.
