Steel and Stainless Steel Ceiling Grilles
Description

Made to measure panels for cladding ceilings or concealing service ducts, manufactured from pressure locked gratings.

The degree of visual screening is determined by the size of aperture and depth of the flat bars, which are entirely variable depending on preference. Cross-pressed gratings which have flat bars of equal depth or pressed gratings with closely spaced flat bars are generally recommended to achieve a reasonable degree of screening.

Gratings can also be designed with load bearing properties for mezzanines. The specification of the panel will depend on the span and loading requirement. Carbon steel products are supplied in a hot-dip galvanized finish with an option for an additional polyester powder coating to any RAL colour.
