Definitely borrowing a lot from these for ours. I like the beam underneath, instead of the full caps on the ends. I like the regular sized treads, with the neat steel bar to protect the opening instead of oversized (thick) treads to limit the space. They also limit the openness. And I like the wood that you have chosen to offset the powdercoated black steel. I also like the beams offset from the edges, instead of at the extremes. Very nice.
