SD Aluminium provides premium aluminium and WPC fencing, gate and railing systems for both residential and commercial properties across New Zealand. Backed by more than 20 years of aluminium fabrication expertise, our fence systems combine durability, aesthetics and hassle-free installation, giving you a secure boundary that elevates any outdoor space.

Certified Quality – Every system is supported by engineer-approved PS1 documentation, ensuring building-code compliance and peace of mind.

Flexible Installation – Select the method that suits your site: top-fix flange plates for concrete pads, in-ground posts for soil foundations, side-mount or wall-to-wall rail brackets for decks and retaining walls.

Low Maintenance – No painting, staining or sealing required. An occasional wash with mild soap keeps your fence looking new.

Long-Life Durability – Aluminium resists rust and corrosion, delivering decades of performance in New Zealand’s harsh climate.

Design Versatility – A wide choice of profiles, colours and heights—from modern black to realistic wood-grain finishes—fits any architectural style.

Security & Value – Strong construction deters trespassers, and the long lifespan lowers total ownership cost compared with timber or steel.

Eco-Friendly – Aluminium is 100 % recyclable, reducing demand for new raw materials and supporting sustainable building practices.
