发明名称 Beam for a drywall ceiling soffit
摘要 A straight rollformed beam made for use in a suspended horizontal drywall ceiling is modified so that it can be used in a drywall ceiling underhang known as a drywall ceiling soffit. The beam is made with repetitive configurations along the length of the beam that are selectively cut, in the field, so that the beam can be bent to, and then fixed at, a desired angle. Drywall panels are secured to a plurality of such beams that form a framework for the soffit.
