FS 4.4 AS RHOMBOS expanded metal ceiling

Lay-on/hook-on system

FS4.4 AS RHOMBOS is a lowering and movable expanded metal ceiling system for vestibules that permits the use of very large panel formats. It is particularly well suited for use in facilities where large ceiling openings are an advantage with regard to design reviews. The positive-connection system with symmetrical panels can be dismantled easily and without the need for tools. 

  • Panels can be lowered and moved
  • Visible substructure
