Straight Stair (Double Rail)
I-Stair Overview
The straight floating stair, or I-stair, is a structurally efficient monostringer system defined by its clean, uninterrupted geometry and high load-bearing capacity. Its single-run configuration allows forces to be transferred directly and predictably, resulting in minimal deflection and exceptional rigidity when properly engineered. The simplified layout supports precise fabrication, consistent tolerances, and straightforward installation, while remaining highly adaptable to a wide range of tread materials, finishes, and guard systems. This combination of strength, clarity of form, and configurability makes the straight floating stair a reliable solution for both residential and commercial applications where performance and visual restraint are equally critical.
