30-Year Warranty Confidence: Investing in Long-Term Safety
Specifying a balcony system is a long-term decision. Beyond the initial installation, developers and housing associations must consider durability, safety and cost over the lifetime of the building. At AliDeck, we back our products with a 30-year system warranty, giving our customers the confidence that their investment is protected for the future.
Our long-term warranty is more than a marketing feature — it reflects decades of innovation, UK-based manufacturing, and rigorous testing that goes into every component we supply.
Built to Last with Marine-Grade Aluminium
All AliDeck systems are manufactured from 6063 T6 marine-grade aluminium, known for its exceptional strength and corrosion resistance. Unlike timber or composite products, aluminium won’t rot, warp or degrade under weather exposure. This is particularly important for balconies, which are constantly exposed to rain, temperature shifts and airborne pollutants.
Our materials ensure that balcony decking, soffits, balustrades and handrails remain structurally sound and visually consistent — even in coastal or high-rise environments.

Powder-Coated Protection, In-House Quality Control
To enhance lifespan, we powder coat all aluminium components in-house using Qualicoat-standard processes. This means that our finishes maintain colour and durability for years, reducing the need for repainting or replacements.
We offer a powder coating warranty of 30 years, depending on the location, as we carry out a detailed pre-treatment process to ensure maximum adhesion and protection.
Because we control manufacturing and coating in-house, we can offer faster issue resolution and maintain full traceability across batches — something many overseas suppliers can’t match.
Reducing Whole-Life Costs
Choosing a balcony system with long-term durability reduces ongoing maintenance costs, minimises disruption for residents, and increases value for building owners. When paired with our low-maintenance designs and non-combustible fire performance, the AliDeck range provides both safety and economy across the full life of a building.
Our warranty offers peace of mind — not only for regulatory compliance, but also for the long-term financial and operational performance of your development.
