The floor joist spacing is the distance between the centers of any two installed joists. A remove the existing floor and use structural flooring laid at 90 to the joists and fix into the joists. In addition to retrofitting there is a great deal more information about designing with steel joists. See the image below for an example of joists spaced 16 on center 16 o c.

Short pieces of blocking also called cross bridging are added between the joist to prevent sway in the floor. You might need a 3x wood nailer full with of the top double angle section of the joist with nelson sill plate anchors welded alternately to the top angles of the bar joists in order to attach the plywood to the joist.
