Tacke + Lindemann GmbH is a specialist wholesaler of metals and insulation supplies as well as doors, gates, door technology and locking systems based in Dortmund. The Metallservice segment sells metal, insulation accessories and insulation tools primarily to metal-processing customers — in particular industrial insulators, roof and façade builders and industrial metal processors. The Door and Gate Systems segment supplies doors, gates, door technology and locking systems including installation to construction companies, operators of commercially used properties and also sells these products as trade goods to metalworking companies and facility management firms. To expand its product range, the company established its own production for trapezoidal and corrugated sheets in mid-2023 (acquisition of a production hall and three rollformers) and introduced a new ERP system; on average 72 employees were employed. Tacke + Lindemann GmbH is a family business.
