About this detail

Web penetrations in steel beams, including universal beams and columns such as 310UC, 310UB, 360UB, 410UB, and 530UB sections. Penetrations up to specified diameters require 100x10mm stiffener plates welded to the top and bottom of the penetration with 6mm fillet welds to the beam web. Smaller unreinforced penetrations are permitted below specific diameter thresholds depending on the beam size. Minimum clear spacing between adjacent penetrations is indicated.
