The Metsec oversail floor beam system, designed for use without cleats offers maximum economy. The direct connection of C-sections to primary members may reduce component and installation cost. The performance of C-sections used in this system is related to the length of C-section directly sitting on the main support beam known as the bearing length and should be a minimum of 65mm.
