Mono Stringer Staircase

The stringer carries everything. So does the craftsmanship.

The mono stringer staircase is one of the most requested designs in residential and commercial interiors — and one of the most demanding to execute correctly. A single steel spine runs the full rise of the stair, with each tread cantilevering outward from that central support. The result is a staircase that appears to float.

At BAMPRO, every mono stringer is fabricated from structural steel in our Durham shop — engineered to carry the load and built to meet your finish and material specifications. Treads can be fitted in wood, metal, or a combination of both depending on the application and aesthetic.

Common applications:

• Residential interiors — open-concept homes, loft conversions, high-end custom builds
• Commercial and hospitality spaces requiring a clean, modern profile
• Renovation projects replacing bulky traditional framing

Every project starts with a site visit and a conversation. BAMPRO handles concept through installation — no subcontractors, no coordination gaps.
