It is a Schüco Premium Partner (30+ years exclusive) and Renson Ambassador, delivering full turnkey projects from design through production to installation — landmark works include BASF Antwerpen, Posthofbrug Berchem (17,000 m² offices), DronePort Brustem, CM Limburg HQ and the first ASE 80 HI DesignLine installation in Belgium. Led by the Corswarem family (Dirk, An, Jolien), the group booked a gross margin of €5.3M at its 2023 peak but saw profit fall 64% in 2025 to €691K amid Belgium’s construction slowdown — though equity rose 44% and debt dropped 30%. |
