Steel Deck


Steel deck is a cold-formed corrugated steel sheet supported by steel joists or structural steel. It is used to support the concrete or insulating membrane of a roof. Canam Asia has steel deck roll formers at its plant in Ra’s Al-Khaymah (R.A.K.), north of Dubai in the United Arab Emirates.

Steel Deck Diaphragm

The steel deck sheets used for roofs and floors provide support for gravity loads between the joists and/or beams. Once installed, these sheets can also be used as a horizontal brace and the steel deck therefore acts as a diaphragm.

The fluted deck is equivalent to the web of a horizontal beam of which the flanges are the perimeter structural members connected to the deck. The span of that horizontal beam is defined by the distance between the vertical lateral load resisting systems connected to the deck.

The secondary elements form stiffeners for the web produced by the fluted deck. As for normal beams, the deck (web of horizontal beam) must be attached to the perimeter members (flange of horizontal beam) to ensure transfer of the shear forces.
