Who We Are

At KeenWorx, formerly Fearfab, we transcend engineering and steel fabrication, serving as your trusted partner in quality-driven metalwork solutions. Based in Sydney, we specialise in crafting complex mechanical devices, high-quality fabrication, and engineering design. Since our establishment in May 2018, we’ve built a stellar reputation, recognised for impeccable service and craftsmanship. Our loyal clients stand as a testament to the quality of our work, with the majority of our projects originating from word-of-mouth referrals.

In September 2022, we expanded to a larger workshop in Smeaton Grange, doubling our capacity while maintaining high standards. One of our most significant projects was a collaboration with Acciona on the Sydney Light Rail project. This endeavour showcased our capabilities in integrated service cabinets, handrails, benches, bins, and panels.

Proud of our ability to exceed expectations, we invite you to contact us today to discuss your unique requirements and turn your vision into reality.
