LIGHT WEIGHT METAL FRAMING MEMBER

摘要

The present invention provides for a lightweight metal framing member having a central web and two parallel spaced apart side walls extending upwardly from the sides of the web. The framing member has at least one longitudinally oriented rib extending the length of the web of the framing member to aid in reducing shrinkage and twisting of the framing member when non-symmetrical reinforcing structures are found in the framing member.
