A progressive metal ceiling system perforated (Acoustical or Vented) or solid, offering an easy to install ceiling/soffit in areas that would not need 100% immediate accessibility of every panel yet provide access when required with only a few simple steps. The system if installed for exterior applications provides superior wind load compliance, subject to proper installation of the support grid when meeting local building wind load codes. Interior application of the system offers simple installation of ceiling panels that requires a multiple number of panel modifications to suit complex non geometrical ceiling configurations.
Access panels are fitted with torsion springs when required for easy access to plenum where needed or dismantling of nearby panels (Tab and Slot Type) for access to plenum areas not reached through the torsion spring panel itself. Support system will require standard readily available hat channels in size and gauge as per applicable building codes and provided by installing Contractor.
