Deltabi Costruzioni, has taken charge of the design and the tailor-made realization of an industrial steel spiral staircase, commissioned by a customer with an industrial company in the island of Mahè, in the archipelago of Seychelles. The spiral steel staircase is made of hot-dip galvanized steelwork. The process of hot-dip galvanizing involves the processing of metals, mainly the use of steel, where the pouring of zinc over the metal structure is implemented. This type of processing has the ability to increase the strength of the material, preventing galvanic corrosion over time and the early onset of rust due to weathering. This steel spiral staircase has been custom made following the needs and requirements of the customer, trying to maintain a visual and functional coherence with the internal context of the industrial structure.
