From the outside, it looks simple—clean vertical lines, rich timber tones, and a solid elevated platform. But every detail in this QHI National build tells a story of precision, compliance, and quality construction.
This isn’t just another deck. It’s a showcase of how smart design and experienced hands can create a space that’s functional, beautiful, and built to last.
The Structure: Steel Where It Counts
At the core of this build is a fully engineered steel frame, built using Firmlok box beams. These aren’t just chosen for looks—they’re selected for their long-term performance.
•No warping, no rot, no termite risk
•Clean lines and quick install time
•Ideal for high decks, especially in coastal or high-humidity zones
QHI National installs Firmlok across hundreds of projects a year because we know it delivers strength and consistency every time.
The Decking: 90x19mm Merbau, Fixed Right
The decking here is 90 x 19mm merbau, screw-fixed for strength, stability, and aesthetics. We never nail decking on high-performance builds like this—screws hold tight over time, especially when timber expands and contracts with the seasons.
Merbau remains one of our top choices for its:
• Superior durability
• Rich, natural finish
• Low maintenance when sealed correctly
• Exceptional long-term performance in Australian conditions
It’s not just a deck—it’s a high-traffic, weatherproof platform for everyday life.
The Balustrade: Engineered Safety Meets Timber Craft
The standout feature? The balustrade.
Designed and built to meet NCC and AS1170 requirements, this system provides full compliance without compromising on visual impact.
Here’s the spec:
• 90x90mm laminated kwila posts: durable, premium, and built to anchor
• 90x45mm kwila top rail: smooth, strong, and sits perfectly in hand
• 42x19mm merbau vertical battens: evenly spaced for airflow, privacy, and code compliance
This balustrade does more than keep people safe—it defines the style of the space. The vertical battens offer both privacy and ventilation, while the merbau grain brings warmth and texture to the entire structure.
Why This Works
This deck hits all the right marks:
•Engineered steel subframe for strength
•Merbau decking for lasting looks and low maintenance
•Code-compliant balustrade that blends safety with sharp design
•Built by licensed professionals who understand both form and function
Whether it’s for an NDIS modification, a family upgrade, or a rental investment—this is the kind of build that adds real, long-term value to your home.
