MetFloor 55 Steel Decking
MetFloor 55 Steel Decking In Detail
MetFloor® 55 is a traditional dovetail re-entrant composite floor deck.
Its profile provides an excellent mechanical key into the concrete slab, offering a strong shear bond performance augmented by stiffeners located in the profile trough. MetFloor 55 presents a virtually flat soffit and only a relatively thin slab is required to meet fire design requirements.

MetFloor 55 steel decking summary
- Shear studs
MetFloor® 55 has a wide trough which provides great flexibility and efficiency when placing shear studs. - Composite beams’ fire performance
Even for two hours fire rating, the top flange of the steel beam does not require fire protection when used with MetFloor® composite deck. - Under floor services
Services are easy to attach to MetFloor® 55, with the ribs presenting a dovetailed recessed groove in the concrete slab at 150mm. This provides the perfect connection for service hangars via a wedge nut or similar fixing device. - Slab’s fire performance
Heat transfer through the small dovetail into the slab is minimal resulting in a lesser slab depth for fire design.
