Two departments. One workshop.
Rigney Engineering runs two departments working side by side: structural steel design, fabrication and installation, and a dedicated plate profiling workshop.

Department 01Structural Steel Fabrication
Structural steel is the core of our business. We work on all types of structural steel: commercial buildings, marine structures, residential structures and more, from the first calculation to the final bolt on site.
- Survey, design and consult
- General and CE certified fabrication
- Installation
Department 02Plate Profiling
Our adjoining workshop is kitted out with three plasma profiling machines that cut virtually any thickness of plate, with absolute precision cutting, drilling and reaming, bevelling, tapping and countersinking.
- Plasma profiling
- Drilling and reaming
- Bevelling, tapping and countersinking
- Guillotine and press brake
Questions we get asked.
What does your structural steel department cover?
Design, fabrication and installation of all types of structural steel: commercial buildings, marine structures, residential structures, agricultural and industrial buildings.
Can you supply drawings, calculations and 3D models?
Yes. We provide structural engineer reports and calculations, full design drawings, fabrication drawings, NC files for CNC outputs and 3D models for client visualisation.
Are you CE certified for structural steel?
Yes. Our structural steel is CE certified to EN 1090 and our welders are certified to EN 1090-2. A certificate of performance is supplied in the O&M manual for every job.
Do you cut plate for other companies?
Yes. Our plate profiling workshop feeds our own fabrication shop and also processes plate for external clients. Send us a DXF or drawing for a price.
What can your plasma profiling machines do?
Our three plasma profiling machines cut virtually any thickness of plate, with precision drilling and reaming, bevelling, tapping and countersinking. A guillotine and press brake handle sheet cutting and folding.
What finishes can you supply?
Paint, galvanising and powder coating, available on both structural steel and profiled plate.
How big is your workshop?
Our Kilrush premises is around 70,000 sq ft, with a 15 ton overhead gantry crane in the fabrication bay and an adjoining plate profiling workshop.
