Open Modern Floating Mono Stringer Stairs

Pricing for custom mono stringer staircases is available on request, as total costs vary based on your specific configuration. Factors impacting pricing include straight versus curved design, overall height, tread materials, finishes, and custom architectural requirements. Acadia Stairs collaborates with homeowners and contractors to develop custom shop drawings and provide specific quotes tailored to individual project specifications.

Structural steel is an ideal material for mono stair stringers due to its superior strength, rigidity, and long-lasting durability. Systems fabricated from heavy rectangular, square, or round steel tubing can reliably support heavy loads while maintaining a slim profile. Steel stringers can also be finished with durable powder coating for enhanced protection in both interior and exterior environments.

A mono stringer staircase features a single central spine that supports the entire stair run, eliminating traditional outer stringers to deliver a floating tread effect. These custom-fabricated metal systems can be configured in straight-line, curved, switchback, or L-shaped layouts. They offer a sophisticated architectural look that complements contemporary aesthetics while meeting standard building load-bearing requirements.

Acadia Stairs fabricates mono stringer stairs using heavy-duty center beams engineered to support 300 lbs per tread. Straight stair configurations can accommodate widths up to 42 inches without requiring additional support posts. Tread plates and riser wedges are constructed with 3/8-inch steel components, providing exceptional structural stability and rigidity across both residential and commercial installations.

Yes, mono stringer stairs can be engineered for both interior and exterior applications. For outdoor installations such as decks, balconies, and garden access, structural steel stringers are paired with weather-resistant materials and durable powder coating finishes. This construction provides long-term resistance against environmental elements while maintaining an open, modern architectural aesthetic in outdoor spaces.

Single stringer staircases offer versatile configuration options to fit nearly any space. Layouts include straight-line runs, L-shaped stairs, U-shaped switchback arrangements, and geometric winder treads. They can also be designed as curved staircases rotating from a few degrees up to 360 degrees, or combined with straight and spiral systems to meet unique architectural requirements.
