What Midroc does

Granitor is a privately held, family-owned Swedish conglomerate headquartered in Solna that delivers integrated engineering, industrial, environmental, and property development services to enterprise, municipal, and consumer customers primarily in Sweden. The group operates through four core wholly-owned subsidiaries — Granitor Electro (electrical installations, security solutions, and property automation), Granitor Systems (industrial automation, robotics, power systems, crane systems, and industrial gates), Granitor Properties (long-term development of commercial and residential property, including the Embassy of Sharing sustainable district in Hyllie, Malmö), and Granitor Miljöteknik (soil remediation, water purification, and underground facility work) — alongside managed specialty subsidiaries Alucrom (blasting and surface treatment), BAC Group (cathodic corrosion protection), and Metalock Engineering (specialized mechanical machining). Granitor also maintains a direct investment arm focused on cleantech and life science ventures.

The underlying technology platform spans multi-discipline engineering and sustainability technology: electrical and security systems for buildings and industrial facilities, resource-efficient industrial automation, cathodic corrosion protection, advanced surface treatment, and environmental remediation. The portfolio previously included Zaphire, a building automation solution that was divested to WAGO in May 2026 to enable international scaling through a global partner. The group established a CSRD-inspired sustainability reporting framework in 2025, and active partnerships with Forum för innanförskap and Samtalsringen (joined June 2026) reflect investments in long-term skills supply and social sustainability.

Revenue is generated through project-based contracts, service agreements, property sales, and commercial/residential leasing, with go-to-market executed via direct enterprise field sales through each subsidiary, supplemented by property listings portals for consumer leasing. Pricing is not publicly disclosed and is quoted per-project. Notable customers and projects include the World of Volvo landmark building, the Käppalaverket wastewater treatment plant expansion, and industrial services for Ovako. The group operates with 1,001–5,000 employees, reported increased turnover and improved results in 2025, and relocated its Solna headquarters to Stjärntorget 1 in February 2026.
