Data is based on deflection limitations in accordance with AAMA TIR-A11 of L/175 up to 13'-6" and L/240 +1/4" above13'-6", with a maximum deflection of 1 1/4". All curves reflect single span conditions, unless noted otherwise.

These curves reflect the limiting value for mullions with horizontals and are based on allowable windload stress for T6aluminum (15,000 psi) and A36 steel (20,000 psi).

A 4/3 increase in allowable stress is not reflected in these curves. For special applications not covered by these curves,please consult your local Oldcastle BuildingEnvelope facility for assistance.TM
