Laser-Cut Steel Floating Stair Structure

At San Francisco Floating Stairs Specialists , the structural backbone of every floating staircase is a precision laser-cut steel system fabricated in our shop to the exact field dimensions of your Bay Area property.

Standard stair fabrication relies on HSS tube steel cut and welded on site — leaving exposed welds, grind marks, and field-applied paint. Our laser-cut system eliminates all of that. Every cut is made in our facility from field-verified measurements. Welding is completed in our shop under controlled conditions. Powder-coat finish is applied before delivery. Nothing is modified on site.

The result is a steel structure with no exposed welds, no grind marks, and no rough finishes. Every connection is concealed. Every surface is flush. The finished structure looks like it was manufactured, not assembled — because it was.

California seismic requirements add structural demands that traditional HSS stair fabrication often fails to account for. Our laser-cut structures are engineered to meet California CBC lateral load resistance requirements. Load calculations are stamped by a licensed structural engineer and included in your permit documentation.

For Bay Area lofts, commercial spaces, and multi-unit residential buildings, our steel structures handle high load capacity requirements without compromising the visual lightness of a floating design. Each mono or duo stringer profile is calculated for the specific span, load, and tread configuration of your project.
