Metfloor 55 Steel Decking
MetFloor® 55 is a traditional dovetail re-entrant composite floor deck. It's 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 a relatively thin slab is required to meet fire design requirements.
MetFloor® 55 has a wide trough which gives you great flexability 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® 55 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 centres. This provides the perfect connection for service hangers via a wedge nut or similar device.
Slab's Fire Performance
Because the dovetail has a very small opening very little heat is transferred through the slab if there is a fire. So when you design for fire purposes you will need a similar slab depth.
