Floor & Roof Systems

Custom-Designed. Factory-Built. Site-Ready.

The PosiStrut System is an engineered timber and steel hybrid product used for both floor and roof applications. Each PosiStrut joist is specifically designed for the job before being manufactured to an exact length — no further cutting or modification is required on site.

The open web design allows plumbing, electrical and HVAC services to run through without drilling or modification. Every joist is custom-designed to your specific load conditions, span and support requirements — whether used in a floor or roof structure.

We manufacture and supply PosiStrut trusses for floor and roof applications, designed using MiTek engineering software, and deliver across the Manawatu, Wairarapa and Wellington regions from our Levin facility.

How It Works

From Factory Floor to Your Build

📐

Custom Engineered Design

Each PosiStrut joist is engineered from your consented plans using MiTek design software. Spans, load conditions, service voids and penetrations are all resolved before a single piece is manufactured — whether for floor or roof.

🏭

Factory Prefabricated

Every joist is manufactured to the exact specified length in our Levin facility — no site cutting required. Strongbacks and crossing members are pre-fitted and joists are bundled and labelled for easy installation.

🚚

Delivered & Builder-Installed

Joists are delivered to site by truck and lifted into position using a hi-ab, ready for your builder to install directly. The open web design means trades can run services straight through — no extra drilling or modification needed.
