S4 hook-on system

Metal ceiling with hook-mountable individual panels

The modern S4 metal ceiling system has a concealed substructure. The individual panels are hook-mounted in the system and are easy to remove. On request, the metal ceiling can be produced to be resistant to lifting, wind action or thrown balls, and also foldable with torsion springs (S4.7 K-TS), and a uniform seam pattern is assured even after maintenance work. 

  • Optionally available with cooling meanders as a cooling ceiling
  • Flexible design options
