Exterior Metal Ceilings

Metal Ceiling Systems and Suspension

Using metal ceilings for exterior soffits, canopies, and other architectural applications has been a growing trend over the last several years. While similar to an interior application, special care must be taken for exterior ceilings due to exposure to natural elements, such as inclement weather, bugs/animals, wind, etc. 

The industry recommended ceiling system for this type of application is made up of brake-formed metal panels and a torsion spring suspension system. The torsion springs are fitted into  slotted heavy-duty aluminum extruded tee bar grid. This grid system provides significantly more strength than standard interior 15/16" grid, and the torsion springs allow for butt-joint edge conditions and a clean, monolithic appearance.

The panels can be made out of aluminum, steel, or stainless steel, and be provided in a wide range of colors and finishes (anodized, PVD, brushed, bright, painted powder coat, wood, etc.). Panel size can reach a maximum of 45" x 120", are class A fire rated, and have a bug screen on the back to prevent unwanted guests from living behind the panels. They can be perforated for acoustics, with micro-perforations that allow sound to pass through and be absorbed by the acoustical infill behind. 

Cam-Locks

Most exterior panels are rated to withstand a certain amount of wind load, which can vary based on the size of the panel. One extra layer of security necessary to prevent the ceiling from becoming disturbed is the use of cam-locks. Cam locks are placed on the edge of panel and released by using a small 3/8" access hole on the panel face. After the cam-locks are released the panel is held by the torsion spring (snap-in) suspension system, and can be individually removed for easy access.
