The AC-400 Series are torsion spring ceiling systems.
The system can be flat, curved, radial, vaulted or
domed. They are designed to attach to a factory
modified ceiling grid system. It can be non-perforated
or perforated with choices of steel or aluminum. The
only restriction in the ceiling panel size or shape is
the availability of raw material.

• Multiple finish options such as painted, metallic,
  faux wood or real wood.

• Multiple perforation choices that can vastly
  affect the noise reduction

• coefficient (NRC), the sound transmission
  coefficient (SRTC), and the reverberation time.

• Torsion springs are factory attached allowing
  considerable field labor savings.

• Panels PVC film is removed at the factory and
  each panel is individually poly bagged to provide
  considerable labor savings at the site.
