When a critical part breaks and the OEM stopped making it years ago - what do you do? 🔧

That's exactly the moment Leussink's Specialised Services team steps in. From urgent breakdown response and reverse engineering of obsolete components, to digital CMM Pass/Fail reporting and our own in-house logistics division - we keep Australian plants running when others have run out of options.

40+ years of saying yes to the jobs other engineering firms turn down.🔗 https://www.leussink.com.au/engineering/specialised-services/

From Unanderra to Kazakhstan - Leussink Engineering is restoring rolling mills around the world. 🌏

Our team specialises in extending the life of steel rolling mills through precision refurbishment, on-site machining, and patented Gap View technology that takes the guesswork out of wear and tear.
We've worked on projects for ArcelorMittal (the world's largest steel producer), and partnered on mill refurbishments across Romania, Italy, and Kazakhstan - but no job is too big or too small.

If your rolling mill is due for an audit, a refurbishment, or a full overhaul, talk to the team that's been keeping mills running for decades.

To every mum in the Leussink family - and across Australian manufacturing - happy Mother's Day. 💐
We're a second-generation family business, and we know better than most that the strongest workshops, the steadiest teams and the best-run businesses all have one thing in common: the women who hold them together.
To every mother on the tools, in the office, in logistics, and at home raising the next generation of tradespeople and engineers - thank you for everything you do.
From all of us at Leussink Engineering, have a wonderful day. 🌸

Today, we pause and remember. 🌹
At Leussink Engineering, we are proud to honour the brave men and women who served and sacrificed for our country. ANZAC Day is a reminder of the courage, mateship, and resilience that define the Australian spirit - values that we carry with us every single day.
Lest We Forget. 🕊️

Some stories are worth telling.
It started in 1977 - a garage in Wollongong, a passion for precision, and a dream to build something special. What began as a one-man operation has grown into one of Australia's most trusted engineering and manufacturing businesses, now proudly carried forward by the second generation - Jason, Ray, and Kenley Leussink.
Over 40 years later, Leussink Engineering isn't just still standing- it's thriving, with clients and projects spanning Europe, Asia, the UAE, and New Zealand.
We're incredibly proud of where we've come from, and even more excited about where we're headed. None of it would be possible without the loyal clients, hardworking team, and community that have supported us along the way.
If you'd like to work with a team that brings decades of expertise and genuine care to every job, we'd love to hear from you. 👇
