Manage floor height while providing fire, vibration, and sound control. Steel-based long-span composite solutions are fire-rated without protective coverings. Optional acoustical treatments absorb sound energy and can provide architecturally exposed deck options that eliminate suspended or furred ceilings.

In addition to enabling flexibility in anticipation of occupancy changes over the service life of the building, certain long-span composite systems are ideal for the renovation of existing buildings. Lightweight deck components allow for maximum maneuverability without resorting to heavy lifting equipment. Lightweight concrete topping option reduces loads to existing supports and foundations.
