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.

Available in gauges: 0.9, 1.2
Prices from: £24.20 per square metre.
