MODERN STRENGTH.
ARCHITECTURAL BALANCE.
Double stringer stairs are supported by two structural steel beams positioned along the sides or beneath the outer portions of the stair treads. This symmetrical configuration creates a strong visual foundation while preserving the open and contemporary appearance of the staircase.
The two-stringer design is especially well suited for wider staircases, larger layouts, landings, and projects where structural performance and architectural presence are equally important. Depending on the desired style, the steel stringers can remain exposed as a prominent design feature or be incorporated more subtly into the finished staircase.
Every double stringer staircase by The GLASSO is custom designed around the dimensions, structural conditions, and interior concept of the individual project.
A double stringer staircase uses two structural beams to support the stair treads. Unlike a mono stringer system, which relies on one central beam, a double stringer configuration distributes support across two parallel steel members.
The stringers may be positioned directly beneath the outer edges of the treads or set slightly inward to create a lighter, more contemporary profile. This flexibility allows the staircase to be adapted to different widths, layouts, landing configurations, tread materials, and railing systems.
The exposed steel structure becomes part of the architectural design, while premium hardwood treads soften the appearance and add warmth to the finished space.
WHAT IS A DOUBLE STRINGER STAIRCASE?
ENGINEERED FOR
STRENGTH AND PRECISION
A successful double stringer staircase begins with careful structural planning. The dimensions and placement of each steel stringer must be coordinated with the stair width, floor-to-floor height, tread configuration, landings, attachment points, and surrounding building structure.
Our process incorporates structural engineering and detailed fabrication drawings to ensure that every component is manufactured and installed correctly. The steel frame is fabricated off-site whenever possible, reducing field welding and allowing for a cleaner, more controlled installation.
Once the structure is installed, the staircase can be completed with custom wood treads, railing systems, handrails, metal finishes, and integrated lighting.
