UL number for tube beams (only columns)?

Hello Jason and thank you for utilizing ASK Hilti! Typically tube steel members are better utilized for column design and not as efficient as an open profile member (such an I-Beam). At this time there is not a listing for a hollow section tube member to be used as a beam however, from a steel protection perspective, the tube steel member thickness will be determined through the use of a column design. This will mean that the intumescent thickness will be calculated for a four sided fire exposure and not a three sided fire exposure.
