What Metalock Engineering does

Metalock Engineering is a Sweden-headquartered, privately held on-site machining and specialist repair group, wholly owned by Midroc Europe and self-described as the largest on-site machining engineering group in the world. The company delivers emergency and planned repair, reclamation, and precision-machining services directly at customer sites, eliminating the cost and downtime of dismantling large industrial assets.

Its service stack spans on-site machining (including crankshaft and laser-guided machining up to 30 metres in diameter), on-site CNC machining with Siemens controls, orbital machining, shaft recovery, thermal spraying, specialist welding, metalock cold casting repairs, mechanical manufacturing and overhaul, alignment and metrology using FARO 3D laser scanning, and mobile laser cladding. These are delivered by a workforce of approximately 400 engineers through seven regional offices in Sweden, the UK, Germany, France, India, Saudi Arabia, and the UAE, covering roughly 100 countries and around 200 active projects.

Metalock serves heavy-industry operators across marine and offshore, naval construction, power generation, steel (including SSAB, Corus/Tata Steel, Dofasco, and Aceralia), cement (Lafarge, Rugby), petrochemicals (Shell Expro, Preem), paper, mining and aggregates, and pressing and forging. The business model is project-based B2B services sold on a per-engagement basis, with revenue tied to emergency call-outs, planned overhauls, and specialised reclamation work. Preem Refinery, also owned by Midroc Europe, is a named customer, creating a captive revenue channel alongside external industrial clients.
