The ultimate in lightweight steel decking for all multi-rise applications
MetFloor 55 is a traditional dovetail re-entrant shallow composite floor deck, and is available in a range of steel grades. It is our most established steel decking system, highly versatile and popular worldwide.
The MetFloor 55 dovetail profile provides an excellent mechanical key against the concrete slab, offering excellent shear bond performance, augmented by embossments in the profile webs and stiffened by ribs within the trough.
MetFloor 55 presents a near-flat soffit and only a relatively thin slab is required to meet fire design requirements. For details on slab depths required for specific fire ratings, please download the MetFloor brochure, or alternatively download the SCI Assessed MetFloor software.
