Culture house along the banks of the Sambre

The provincial cultural centre in Namur was built in the early 1960s and since its renovation and expansion, which included the addition of the spectacular ‘Tambour’ theatre hall, has been known as the ‘Delta’. Magnelis steel was used to contrast with the bamboo facades and to create the large movable vertical shutters that protect the west facade from the sun. Custom perforated sheet metal (71 %) was used for all parapets, which are made of 2 mm thick galvanized steel. The ‘Tambour’ rests on a central steel column (diameter 300 mm) and twelve arms in AE355 steel (355 N/mm²), while seven peripheral columns (diameter 150 mm) absorb any asymmetrical loads. Steel has also been used for the suspension systems of the technical equipment in the various theatre halls and for a stairwell in which the stairs are supported by 2 mm thick sheet steel elements, without the need for wind bracing with diagonal struts.
