After standing empty for forty years, the restored Predikherenklooster in Mechelen has been given a new lease of life as a city library. The monastery was built in the seventeenth century and is made up of four wings around a square courtyard. One of the biggest challenges during the restoration was the repair and reinforcement of the monumental wooden roof trusses and attic floor. The existing roof construction has a self-supporting and insulating skin on steel trusses, which are, in turn, attached to the horizontal rafters of the existing wooden roof trusses. As far as was possible, the steel trusses have been concealed to let the authentic library attic appear to its full advantage. All the other steel was also hidden from view, with the exception of the columns of the mezzanine floors. In total, the project used approximately 160 tonnes of S355 steel in the form of hot-rolled profiles.

The Corelio site on the Gosset business park in Groot-Bijgaarden, just south of the Brussels Ring Road, used to be a road-side storage building. However, it had a great deal more to offer than that and is now being transformed into a multi-layered and multifunctional business park for multiple users. This work, part of a wider ecological transformation, will allow the building to excel as a versatile office space. The building has been completely stripped of its outer shell, repackaged with a well-insulated lightweight outer wall made of steel liner trays and finished with white corrugated steel sheets. Cantilevered steel boxes are suspended from the facade at a few strategically chosen places, but the most striking feature is the open steel structure on the facade. The intriguing pattern of horizontal bands clad with three types of perforated corrugated sheeting lends the building aesthetic refinement and gives rise to a fascinating interplay of light and shade.

An existing supermarket and two adjacent houses have been demolished and replaced by a new supermarket plus a restaurant and apartments. To maximise the useful height in the supermarket whilst complying with urban development regulations, steel roof girders were installed above the ground floor. These comprised HE 300 B sections of S235 steel on concrete columns with steel decking, hyperstatically constructed with three approximately 18 m spans, 5 m apart. The columns and beams of the front facade are also made of steel. Finally, the roof and facade of the apartments were finished in weatherproof steel, and the passage on the front of the upper levels in perforated weatherproof steel panels. The weatherproof steel is mounted on steel columns and girders via a steel substructure. A total of 83 tonnes of structural steel was used in this project.
