S4 RHOMBOS expanded metal ceiling

Lay-on/hook-on system

The S4 RHOMBOS system is an expanded metal ceiling with a concealed sub-structure. The respectable seam width of 2 mm helps to create a very homogeneous look and feel to this ceiling. The individual panels are hook-mounted in the system with positive and torsion-free connections, and are easy to remove. After that, they are easy to remove at any time. 

  • Suitable for outdoor applications because of wind protection
  • Ball-impact resistant
