Rolled metal building system

摘要

An improved mullion for a building system. The mullion has a plurality of peripheral wall and web sections defining a load bearing structure adapted for supporting the panel in sealed engagement therewith. The mullion is roll formed from thin gauged metal and further includes an integrally formed, hollow body section having portions defining a glazing pocket therein. Structural members are adapted to be disposed within the mullion body for the engagement and structural integrity thereof. The structural members are secured to the mullion body for maintaining the hollow mullion profile under loading conditions.
