Str7d®

Engineered for CAT D conditions.

Designed for cyclone-region and remote-site deployments where structural resilience is critical. Built on the Structra CoreFrame™ platform, with additional reinforcement for high wind classifications, impact resistance, and extreme Australian conditions.

Built on Structra CoreFrame™
Designed for transport, deployment, and long-term structural performance in high wind classification environments.
The Structra CoreFrame™ is a reinforced steel frame platform that underpins our STR7D model. It is designed to handle transport stress, repeated deployment, and long-term structural loads, while maintaining alignment, rigidity, and finish integrity over time. Unlike conventional expandable units, where structural performance is often compromised for transport efficiency, CoreFrame™ is engineered as a permanent structural system first. This is what allows the STR7D® to extend into cyclone-region applications with additional reinforcement, without changing the underlying platform.

Every detail considered. Nothing compromised.

Plumbing
Fully NCC-compliant, WELS-certified fixtures. 16mm PEX piping and simplified on-site connections.
Electrical
Pre-wired SAA-certified electrical system with LED lighting and smart-ready integration. Designed to support real appliance loads and climate systems.
Panel Construction
Polyurethane Panel, High R-value closed-cell foam — moisture resistant, thermally superior, built to last.
Windows & Doors
110 series aluminium frames, double glazed, low-E glass, child locks, metal flyscreens. Doors with triple-lock security.

When conditions get tougher, engineering matters more.

STR7D Engineering upgrades

Structra CoreFrame™
A reinforced structural steel frame platform developed for higher wind loads, improved rigidity, and greater deployment confidence in demanding environments.
CAT D Cyclonic Engineering
Designed in line with Region D wind classifications for cyclone-prone areas.
Impact Resistant Doors & Windows
Upgraded framing and glazing systems designed to improve resistance against wind-borne debris and extreme weather conditions.
Protective Shutter Systems f ff
Deployable external shutter systems providing additional protection against pressure and impact in exposed environments.

Same platform. Reinforced where it matters.

The STR7D® builds on the same base system as STR2®, with structural reinforcement applied at key load-bearing points.

Exterior options, consistent interior quality

A selection of exterior finishes can be applied depending on project requirements and environment. Interior layout and finish remain consistent to ensure build quality and delivery efficiency.

Applications

Built for these environments.

Mining & Resources

Remote site accommodation for FIFO workers in cyclone-rated regions across northern Australia.

Coastal Strip Deployments

Regional workforce housing for farms, vineyards, and rural businesses requiring compliant long-term occupancy.

Remote Infrastructure

Support buildings for remote stations, communications sites, and infrastructure projects in extreme environments.

Emergency & Government

Rapid-deployment housing for emergency response and government projects in cyclone-prone regions.

When conditions are harsh, engineering matters more

The STR7D® is designed for deployments where structural reliability is critical.
