We offer Wide-Span Structure, the utilization of which results in a range of benefits, including reduced foundation costs, high flexibility, column-free internal spaces and less erection times. This long span solution is made to facilitate the consolidation of services without boosting the total depth of floor. The structure ensures that it occupies the same space in structural and service zones. Decreasing the overall depth of floor construction, this is also used for aesthetic reasons. Wide-Span Structure facilitates hanging services under the ankle-deep areas near the beam supports. It also enables web openings in tapering girders. It is entirely self-supporting and have no patches, purlins etc. Provided with structural curved skin, it restrains the tensile edge beams.
