Approximate side cross section of drop area: (feet)
Big I beam Railing The Grid Drop profile Concrete beam
Vertical Measurements
Bottom of Big I Beam to floor: 54 8
Bottom of Big I Beam to top of grid: 6 9
Bottom of Big I Beam to top of concrete beam: 24 2
And the concrete beam is approximately 16 out from the grid edge horizontally that is we would need to drop from that much further out.
