Altech Systems

For three decades, Altech has stood behind the foundations that define New Zealand’s skyline. We approach every system as both structure and story, engineered to perform and crafted to inspire.

Our experience spans structures of scale and complexity. 

Our Chartered Structural Engineers ensure every detail meets the highest structural and safety standards, but our work goes further. We collaborate with architects, developers and main contractors and clients to explore smarter ways of building: reducing materials, refining form, and finding solutions that bring clarity and balance to each project.

The result is architecture that feels effortless. As though it’s always belonged.

Thoughtfully engineered. Purposefully made. Built to last.

We’ve helped shape the skyline and respond to the most demanding design challenges, including:

• Aluminium systems for buildings up to 30 storeys high
• Engineering for wind loads exceeding 5 kPa
• Solutions accommodating inter-storey deflections over 40mm
• Peer-reviewed by New Zealand’s leading facade engineering firms
• Capabilities in extrusion design, 3D modelling, full-scale prototyping
• Extensive testing, including destructive testing and wind tunnel validation

At Altech, we work closely with architects, developers and main contractors throughout the entire design journey, customising our aluminium systems to deliver the most effective solution for each residential or commercial project. Whether the brief is functional, aesthetic, or both, we ensure every detail is carefully considered and expertly executed.

As qualified engineers and local manufacturers, we have the in-house capability to create bespoke products to exacting specifications. Our design and production process is flexible, responsive, and grounded in technical expertise, allowing us to provide tailored solutions that meet each client’s unique needs, with efficiency and precision.

You’ll find our aluminium systems in some of New Zealand’s most recognisable buildings, from commercial landmarks and apartment blocks to retail stores and private homes. Highlights include Hamilton Jets Christchurch, Alexandra Park, and Thompson Park, each project reflecting our commitment to quality, innovation and architectural integrity.

Aluminium is one of the most trusted materials in modern construction, and for good reason. Its unique combination of strength, versatility, and sustainability makes it ideal for everything from large commercial projects to residential designs.

1. Lightweight Yet Strong
Aluminium offers an exceptional strength-to-weight ratio. It’s easy to transport, handle, and install, particularly valuable on high rise buildings or large scale projects where minimising weight without compromising strength is essential.

2. Built to Last
Despite its lightweight nature, aluminium is remarkably durable. It stands up to heavy structural loads and resists wear and deformation, ensuring your designs remain safe and secure over time.

3. Corrosion-Resistant
Perfect for New Zealand’s coastal and varied climate, aluminium naturally resists corrosion. It performs exceptionally well in outdoor and marine environments, maintaining its integrity and appearance with minimal maintenance.

4. Visually Versatile
Aluminium is highly adaptable in form and finish. It can be shaped into sleek, modern profiles or custom architectural forms, and it takes to powder coating or anodising beautifully, offering a wide range of colours and textures to complement your design.

5. Environmentally Friendly
Aluminium is 100% recyclable and can be reused repeatedly without losing its properties. Choosing aluminium supports sustainable construction practices, reducing waste and lowering environmental impact.

Aluminium’s blend of functionality and design flexibility makes it a superior choice for modern architecture. Whether you're aiming for performance, longevity, or visual impact, aluminium delivers on all fronts.
