The FC perforated panel is processed on
the base of FC, NAFC and NALC panels of
our company. With over twenty kinds of types
in existence, we also can design and produce
apertures and patterns according to the
demands of our consumers.
1. Characteristics: high strength, good
decoration performance, good sound-absorbing
ability, fireproofing and waterproofing.
2. Applications: fit for underground, cinema,
broadcasting station, TV station, textile
mill, plants with overrun noise, and sound-absorbing
panels and suspended ceiling panels in gymnasiums
and other largesize public buildings.
