Metal Ceiling Panels are typically supplied up to a maximum of 4’-0” in width and 12’-0” in length.
Metal Ceilings are available both non-perforated (non-acoustic) and perforated (acoustic). Perforation patterns are limited only to the type of material and gauge chosen and available tooling. Presently Nelson offers more than fifty different perforation patterns ranging from diago-nal, staggered to straight as well as round, square and oblong holes.
Our standard acoustical material consists of a Black or Off-White pre-laminated fleece (SoundTex®) typically bonded to the concealed face of the ceiling panel.
