About
Established in 1990, Killarney Precision Engineering Ltd. (widely known as O’Carroll Engineering (OCE)) is the parent company of a group that includes O’Carroll Engineering, O’Carroll Engineering UK, Signature Stairs Ireland & UK. Offering fabrication solutions from feature to standard architectural metalwork, we specialise in commercial feature stairs (commercial and luxury domestic), balcony systems for Modern Methods of Construction (MMC), industrial access systems and walkways. The company head office is in Killarney, Ireland and we also have a London office ensuring we efficiently service clients throughout Ireland, UK and beyond.
Clients – partners of ours are some of the leading construction management firms, architects, contractors, modular build and off-site construction firms, manufacturers and engineering consultants throughout Ireland and UK.
Our unique digitised design-to-fabrication process is designed to enable our customers to manage their metalwork projects more efficiently and cost-effectively.
It encompasses the entire project process, combining digital site data (BIM information or 3-D site survey) with advanced methods of fabrication, digital approval processes and intuitive scheduling to ensure clients get quality tailored products, fabricated to be installed in the most efficient manner and to agreed schedules. We offer a range of finishes on both supply only or supply and fit products from architectural steel stairs, to large volumes of balconies for apartment builds or balustrading to escape stairs.

O’Carroll Engineering’s expertise in certified, industrial access systems, walkways, metal stairs structures and balustrades has positioned us as a leading subcontractor to one of the world’s leading ship-to-shore crane manufacturers.
We can offer a full design and structural certification and carry the appropriate professional indemnity and product insurance. An ISO 9001-2015 accredited company, our highly qualified staff operate to the EN 1090 standards in a ‘lean manufacturing’ environment where quality and safety are the priorities. We have also been validated by Achilles BuildingConfidence.
Awards & Industry Recognition
At O’Carroll Engineering, our dedication to engineering excellence, innovation, and quality craftsmanship continues to receive recognition across the construction and steel manufacturing industries.
In 2024, our OCE Modular Balconies™ range received the Irish Steel Award for Residential Balconies – Cantilevered, acknowledging our expertise in modular balcony design, precision steel fabrication, and off-site construction solutions that deliver excellence in both performance and aesthetics.
Continuing this success, O’Carroll Engineering was named Irish Construction Industry Subcontractor of the Year 2025. This award recognised our team’s ability to solve complex engineering challenges through collaboration, innovation, and a solutions-driven approach. From design assistance to on-site integration, our teams consistently find practical, efficient, and safe ways to deliver exceptional outcomes for clients, contractors, and architects.
Also in 2025, O’Carroll Engineering received the Irish Steel Association “Extra Mile Award” for Innovation in Manufacturing Systems. This recognition highlights our ongoing investment in smart manufacturing processes, where new technologies and continuous improvement deliver measurable gains in efficiency, precision, and sustainability.
Together, these awards reflect O’Carroll Engineering’s position as a trusted partner in steel fabrication, modular, off-site manufacturing innovation, reinforcing our reputation for quality, reliability, and intelligent problem-solving within construction and industrial markets.
****As specialists in modular, off-site steel fabrication at scale, featuring modular balcony systems, and industrial access systems, we stick to what we are best at and set-up to deliver efficiently – that means we do not offer structural steel framing type services as it is a different type of steel speciality.

Mission
To integrate design, certification, and manufacturing processes to create innovative, off-site, modular steel products for the industrial and construction industry. We build products that deliver value to our customers through the trust that we build with our employees, clients and supply chain partners. We are dedicated to providing a safe working environment and ensuring the highest levels of quality, while delivering sustainable, customer-centric, end-to-end solutions.
Vision
We are committed to forging a future where our off-site, steel-fabricated products are synonymous with trust, respect, and safety. We strive to make sustainable, competitive products that meet the highest standards of quality and efficiency. We will achieve this vision through close client collaboration, dedication to innovation, continuous upskilling of our valued staff, and the implementation of a unique digitised fabrication process.
* Digitised ‘design-to-fabrication’ process describes how we import Building Information Models (BIM) or 3-D survey dimensions (‘as built’) to capture the reality of site conditions and integrate that digital information with our drawing packages, cutting tools, communication and scheduling systems.
This enables us to deliver on-time tailored products, communicate and collaborate with clients more efficiently, compress the design process and identify and eliminate potential conflicts and costs.
