The structure is made of a steel and reinforced concrete composite that combines the good properties of both materials. Steel parts made under controlled conditions of a factory are filled with a concrete mix on the construction site. A good fire-resistant composite structure is the perfect solution for building multi-storey production and office buildings.
In spring 2016 Maru Metall AS signed an agreement to produce steel structures for a railway snow-shelter tunnel in Norway. The agreement covers about 80 t of steel constructions, which are installed in mountainous and abnormal conditions.
