MetFloor® 55

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 a relatively thin slab is required to meet fire design requirements.

Shear studs – MetFloor® 55 has a wide trough which gives you 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® 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 152.5mm to 150mm centres. This provides the perfect connection for service hangars via a wedge nut or similar device.

Slab’s fire performance  – Because the dovetail has a very small opening, minimal heat is transferred through the slab if there is a fire, therefore when designing for fire purposes, you will need a smaller slab depth.
