About GRITEC
GRITEC specializes in the development, production and distribution of technical buildings in the form of factory-fabricated room cells made of reinforced concrete for public and industrial infrastructure. The range extends from small, non-walk-in transformer stations to large, walk-in buildings consisting of multiple modules in all application-related fit-out stages. In its own metal production facility, the company manufactures standardized and customized doors, ventilation elements and pressure relief components made of aluminium and stainless steel. The service portfolio includes planning and project execution, test engineering certificates (arc fault, heating tests, EMC measurement and calculation, thermal imaging, sound insulation), shipping and logistics, installation as well as renovation and retrofit of existing stations. With more than 1,300 employees at seven production sites in Germany and the Czech Republic, GRITEC serves the energy, gas & water, renewable energy, digitalization/broadband, rail, e-mobility and industrial sectors. Through its subsidiary E4YOU, the company offers concepts for electric mobility charging infrastructure.
