Concrete slab on metal deck transitions through a vertical step over a wide flange steel beam, where the upper and lower slab elevations are controlled by dimension 'A'. A support angle is welded to the beam web with a quarter-inch fillet weld at four inches on center to carry the offset deck condition. Angle sizes vary depending on dimension 'A' relative to half the beam depth, utilizing an L6x4x3/8 for smaller clearances and an L4x4x3/8 for larger clearances. Concrete over metal deck finishes typical at both levels with top of concrete and top of steel elevations sized per plan.
