Southern Steel Windows Ltd is a Southland-based fabricator and manufacturer of Architectural and Fire-Rated Steel Windows and Doors.

Turning architectural vision into engineered reality.

Our team of fabricators and glaziers specialises in designing, manufacturing and installing custom steel joinery for commercial, industrial and architectural projects throughout New Zealand. While every project requires different scope, security, strength, and performance, our approach remains the same.

Understand
Every project begins with the design intent. Working from architectural drawings and specifications, we take the time to understand what’s required, from complex structural details to specialist fire-rating requirements.

Engineer
This is where experience matters. We’re often brought into projects where standard joinery cannot achieve the architect’s vision. We work alongside architects and builders to resolve technical challenges, refine the finer details, and ensure every element can be manufactured without compromising the integrity of the original design.

Manufacture
Every window and door is custom-fabricated in our Invercargill workshop using precision manufacturing and skilled craftsmanship.

Deliver
Whether supplying nationwide or completing installation, we remain involved through to completion to ensure every project is delivered to the highest standard.
