About Us
A Family Business Built on Steel
Queensland-based, Australian-owned, and committed to doing the job right — every time.
Who We Are
Our Story
Diedrichs Engineering & Fabrication is a proudly Australian family business based in Queensland. We were built on a simple belief — that quality fabrication, honest workmanship, and personal service should never be compromised, regardless of the size of the job.
From our early days taking on local structural steel work, we've grown to service a wide range of clients across civil, commercial, residential, and motorsport sectors. Our family name is on every piece of work we produce, and that means everything to us.
We work closely with civil contractors, commercial and residential operators, and individuals who simply need something made right. Whether it's a complex structural steel package or a one-off custom component, no job is too hard and no request is too small.

Our Values
What We Stand For
Australian Standards
Every weld, every drawing, and every certified document meets AS/NZS requirements. Compliance isn't a checkbox — it's how we work.
Family Owned & Operated
We're not a faceless contractor. You deal directly with the people doing the work, from first enquiry through to final sign-off.
No Job Too Hard
From large civil and commercial projects to custom motorsport components and personalised one-off items — we take it all on.
Queensland Based
Locally operated and proud of it. We understand the Queensland market, its conditions, and what our clients need to get the job done.
