A. G. Freiman & Associates performed the structural engineering for the construction of a new Aluminum Mills plant. It is an industrial building with 25' x 50' bays. The 14" deep steel open web joists at 4' 0" span the 25 feet.  Cantilevered 24" deep steel beams span 50 feet. The 5 ton crane girders are bracketed off the steel columns. However, the 15 ton crane girders are supported on separate columns adjacent  to the building columns.

Overall picture of the erected structural steel.
