At the former military airport in Brustem, a gatehouse and new aircraft hangar symbolise the future of the fledgling drone industry. The facade and roof of the shed are both made of metal sandwich panels and form a single whole, whilst preformed steel plates are used for the curves in the ridges. The decision to use spatial steel truss structures was driven by the need for a large area free of supporting columns to stable the aircraft. The building is made up of two main volumes in the form of two porticoes of lattice girders converging on a central column. The 6,650 m2 hangar will therefore only have one central row of columns, for which a W-profile lattice structure has been chosen. The top and bottom rail are made of rolled H-profiles in HEA180 and HEA200 respectively, whilst internal members are square box sections (90/4; 100/4; 120/4). Steel grade S235 was used as standard, except for the bottom rail of the main trusses which is in S275.
