Designing for the Future
Steel isn’t just for commercial buildings and farm sheds anymore — it’s quickly becoming the material of choice for smart, modern residential design in New Zealand.
How We Got Here
Steel made its mark in the commercial sector with hot-rolled beams and light-gauge partition walls. It then transformed the rural landscape through cold-rolled portal sheds.Today, it’s reshaping the housing market. Major national home builders are now using light-gauge, cold-rolled steel frames and trusses as a faster, more efficient alternative to timber.The shift is well underway — and growing fast.Steel is the New Standard
Steel-framed homes are no longer a niche option. They’re a mainstream, practical solution embraced by designers and builders across the country.
Designing in steel has never been easier:
GIB® provides a steel-specific bracing calculator and fire-rated systems.
James Hardie and Winstone Wallboards offer steel fixing details.
CAD libraries now include light-gauge steel components.
NASH Standards (Part 2, 2019) and E2/AS4 are cited in the NZ Building Code as Acceptable Solutions.
Steel is fully integrated into modern design workflows.
Why Designers Choose Steel
Looking for longer spans or more open space? Steel is the solution.
Use it where timber falls short:
Large or complex spans
Sloping or narrow sites
High-moisture environments
Its high strength-to-weight ratio allows for creative, cost-effective design — without compromise. Use it selectively or across the entire build.
Every Axxis® steel frame includes:
A 50-year durability statement from New Zealand Steel
A PS1 design certificate demonstrating compliance with NZBC Clause B1 (Structure)
