About WEGRA Anlagenbau
WEGRA Anlagenbau GmbH Westenfeld is a medium-sized company with more than 100 employees that has been delivering solutions in plant engineering, steel construction, industrial construction and building services supply systems since 1990. Its range of services extends from structural and workshop planning to the fabrication and erection of steel structures, hall structures with crane systems, platforms, stairs and railings through to turnkey complete construction across all trades. In the field of energy technology, WEGRA develops and manufactures, together with its subsidiary EAW Energieanlagenbau, combined heat, power and cooling (CHP) units and absorption chillers of the WEGRACAL series. Further areas include metal construction for roof and wall, vessel construction (buffer tanks, stainless steel tanks for food production), electrical engineering with in-house switchgear fabrication, HVAC, plumbing, photovoltaics and agricultural technology as a GEA Solution Center. The materials processed are primarily steel (including S 235) and stainless steel, in coated or galvanized versions. Customers come from industrial and commercial construction, agriculture, energy technology and public institutions. Headquarters are in Römhild-Westenfeld (Thuringia); the energy technology production facility in Hildburghausen has existed since 2011.
