Steel Joist Girders

Joist Girders are open web steel trusses that serve as primary framing members. They are designed as simple spans to support concentrated loads for a floor or roof system. These concentrated loads are normally considered to act at the top chord panel points of the Joist Girders. See the point load configuration diagram below for designations. For more information, see the New Millennium Steel Joists and Joist Girders catalog.
