The project concerns the construction of sugar processing refinery building in Lagos, Nigeria. Our contract included the design, the construction and the painting system of the Steel Structure. Moreover the supply of steel sheets for concrete floors and side and roof cladding was included in our scope of work. The weight of the steel structure was counted to three thousand tons while the total surface of the building exceeded twelve thousand square meters. The duration of the particular fabrication was ten months. Remarkable features are the height of the building (forty meters) and the span of the roof (forty four meters).
