A ceiling suspension system has support members that are interconnected to support ceiling panels. The ceiling suspension system is suspended from a building. Each of the support members has a lower surface that is patterned and different in textural appearance than other portions of the support members to define patterned lower surfaces. For example, the patterned lower surfaces may have non-smooth textures that are uniform and symmetrical, or non-uniform and irregular. The patterned lower surfaces may have three-dimensional features such as lines, slots, dimples, protrusions, peaks and valleys and/or cross-hatching, which may be roll-formed on capping on the support members. |
