K-Span Roofing System uses high quality, high grade, pre-coated Galvalume Steel as the basic raw material. Usually, cold rolled or hot rolled processing technique has been followed to design this Trussless Roofing System. The panel forming and installation is a 100% on-site process. K-Span system arch roofs can be installed on masonry brick, concrete or steel structures, eliminating the need for a conventional roof support structure. As its result, this roofing system minimizes overall construction cost of structure. Binox is capable of erecting arch structures on-site, with spans varying from 4 metres to 40 metres in width. The length of the building or the length of the roof is not constrained. This roofing material can endure damaging effects of harsh weather. It is quick to install and it can be accessed at reasonable price. K-Span system arch buildings and roofs can be adapted to fit existing infrastructure or be considered as a standalone solution for new projects.
