What Omis does

OMIS S.A. is a privately held Polish industrial contractor that designs, prefabricates, and erects steel structures and delivers turnkey EPC projects for the energy and industrial sectors. Founded in 1999 on the basis of a team collaborating since 1988, the company operates from two production plants in Ostrołęka totaling 32,050 m² and 1,000+ tons/month of fabrication capacity, employing 400+ staff including 70+ engineers, designers, and managers. Its core offerings span four interlocking service lines: steel structure prefabrication (elements up to 60 tons and 5.5 × 5.5 × 27m), general contracting including EPC delivery, in-house design using TEKLA, IDEA StatiCa, and SolidWorks, and industrial & energy engineering covering flue gas treatment (SCR, FGD, DeNOx), biomass handling, and hydrogen-related installations.

Technology is anchored in CNC production lines from Voortman, Dural, and DURMA, advanced welding (PULSE/TIME, Fronius stations) certified to EN 1090-2 and EN 3834-2 with IWE/IWI engineers, in-house non-destructive testing, FROSIO Level 3 corrosion supervision, and the StruM.I.S. ERP/MRP system integrated with TEKLA Structures for full production traceability. Manufacturing management is being extended through a PARP-funded Industry 4.0 program adding AGVs, industrial robots, and electronic document management.

The company generates revenue primarily through one-time project contracts (steel structure delivery and EPC), supplemented by ongoing maintenance and modernization services, all priced per project with no public rate card. It sells directly to enterprise clients — utilities, power generators, steel producers, and industrial manufacturers — across Poland and 15+ European countries, supplemented by subcontracting relationships with Westinghouse (AP1000 nuclear), Voestalpine (Hy4Smelt green steel), and Salzgitter (SALCOS). Marketing is relationship-driven via trade-fair participation and a small digital footprint (LinkedIn, YouTube) rather than outbound demand-gen.

Revenue model

1. Steel Structure Prefabrication and Delivery: Design, prefabrication, and delivery of steel structures including boiler support structures, industrial frames, ducting, tanks, and custom oversized components. Revenue recognized upon delivery of fabricated elements to client sites, typically project-based with durations from weeks to over a year.
2. General Contracting (EPC): Full project delivery from concept to commissioning under EPC or general contractor formula, covering design, fabrication, installation, and turnkey solutions for energy and industrial facilities. Revenue from comprehensive project contracts for power plants, district heating, biomass systems, and industrial buildings.
3. Industrial and Energy Engineering Services: Engineering, modernization, and servicing of technological systems including flue gas treatment (SCR, FGD, DeNOx), biomass handling systems, steam pipelines, hydrogen installations, and electrostatic precipitators. Ongoing maintenance and modernization contracts generate recurring service revenue.
