ComFlor® 51 Steel Decking

ComFlor® 51 steel decking is a traditional dovetail re-entrant composite floor deck.

The profile provides an excellent mechanical key into the concrete slabs, offering a strong shear bond performance, which is augmented by cross stiffeners located on the profile trough.

ComFlor® 51 presents a virtually flat surface and relatively thin slab is required to meet fire design requirements.

Key Benefits of ComFlor® 51 are:

  • Fire resistance and flat soffit.
  • Slab and beam performance.
  • Service attachment.
