In the realm of staircase design, Double String Stairs remain one of the most dependable and visually versatile structural systems. While modern innovations like floating and mono stringer stairs dominate minimalist and industrial spaces, double string stairs hold their own as a timeless, highly customizable solution that appeals to homeowners, interior designers, and architects alike. These stairs offer unmatched stability, flexible design applications, and a classic architectural profile that can adapt to virtually any interior or exterior setting.
At Modern Stairs Plus, we pride ourselves on delivering high-quality, fully customized Double String Stairs for both residential and commercial applications. In this comprehensive guide, we’ll dive into what makes double string stairs so popular, how they are constructed, and how they can be adapted to meet today’s aesthetic and structural requirements.
Double string stairs are staircases that use two structural stringers—typically placed on either side of the stair treads—for support. These stringers can be visible or hidden and are made from various materials including steel, wood, or concrete.
Key Features:
1. Structural Strength
With two points of support, double string stairs offer exceptional load-bearing capacity and overall durability. This makes them ideal for both residential and commercial projects.
2. Design Versatility
From traditional to ultra-modern designs, double string stairs adapt easily to various interior and architectural styles. They can be fabricated with wood, metal, or a combination of both.
3. Aesthetic Options
Double string stairs can be designed with open or closed risers, multiple railing styles, and unique tread materials, giving designers and homeowners a broad creative palette.
4. Code Compliance
Double stringers make it easier to meet stair code regulations in Canada, including tread support, handrail integration, and spacing requirements.
5. Enhanced Safety
The dual stringers provide redundancy and stability, creating a solid and safe stair solution for multi-level structures.

Classic Double String Stairs
This is the most traditional form, with two side-mounted stringers and wooden treads. It’s ideal for classic and transitional interiors.
Steel Double String Stairs
Perfect for industrial, commercial, or modern homes, steel stringers provide strength and a sleek aesthetic. Powder-coated finishes are available in various colours.
Floating Double String Stairs
These create the illusion of floating steps while maintaining structural integrity through side-mounted stringers and concealed fasteners.
Sawtooth Double Stringers
A design-focused variant with angular cuts along the stringer edges, adding a geometric, architectural flair to the staircase.
Inset Double Stringers
Stringers are placed below the tread level, partially hidden from view for a cleaner, more refined aesthetic.

Raw metal finishes, exposed bolts, and dark wood treads create a rugged, urban vibe.
3. Biophilic Design
Wooden elements, plant-integrated railings, and natural lighting make stairs feel organic.
