Open Grid Ceiling Systems

General Definition

• Open grid or open cell ceiling systems are a type of divided ceiling made from intersecting rails that form a grid pattern with empty space in the center of each grid. Sometimes the space is filled with other decorative or lighting components. The rails are typically made from metal, but may also be ceramic or ceramic-coated. A variety of colors and powder coatings are available, depending on the manufacturer. Panel sizes can also range from several inches across to 4 feet or more.

Suspension

• Open grid ceilings are typically suspended from the original ceiling surface. The first part of the system installed is the suspension trim, which frames the entire grid area and often the panels themselves for extra support. The gridwork itself is then installed using brackets or high-strength suspension wires. Grids may be installed in pieces that are locked together with clips to make the ceiling look continuous.

Benefits

• Open grid ceilings help commercial building owners disguise ceiling tiles or ceiling areas they would rather not have people see. The grids can be positioned at a variety of heights, allowing the owners to control how high the ceiling goes while still leaving a feeling of openness. Because the grids are often empty, it is much easier to install lighting or work on appliances in the ceiling above than it would be with an alternative, fully covered ceiling.

Optional Features

• Because open grid ceilings are designed in part to be decorative, many optional features are centered around how the grid looks to viewers. In addition to custom sizes, some manufacturers offer curved edges to set apart the grid ceiling from other parts of the room. Coatings, such as zinc/aluminum layers, are also available for ceilings in areas that may be more susceptible to corrosion.
