Custom Floating Staircases

Building a DIY floating staircase requires precise planning, structural engineering, and proper permits. Homeowners can install custom prefabricated systems using single or double steel stringers supplied with detailed installation guides. You will need to securely anchor the stringers to structural framing, attach the tread brackets, and install treads and railings. Technical support is available to assist throughout the process, though professional contractor installation is often recommended.

Floating stair designs utilize single or double stringer configurations depending on structural needs and aesthetic preferences. Single stringer options include rectangular steel tubes, square tubes, round tubes, or tri-frame pipe systems acting as a heavy-duty central beam. Double stringer systems utilize two parallel support members under treads, incorporating structural steel tubes, steel channels, I-beams, aluminum, or stainless steel to create an open, floating appearance.

Custom floating staircases accommodate a wide variety of tread materials to match your architectural vision and interior decor. Tread material options include traditional wood, durable steel, sleek stainless steel, natural stone, contemporary glass, slip-resistant rubber, and ceramic tile. These treads attach securely to laser-cut tread plates or angle iron carriers engineered to deliver extreme rigidity and lasting performance across residential and commercial settings.

Yes, custom floating staircases can be fabricated for both interior and exterior installations. Exterior applications include decks, balconies, rooftop spaces, and garden access. For outdoor stairs, weather-resistant materials such as stainless steel, aluminum, or durable powder-coated steel are utilized to protect against the elements. Each exterior system is engineered to handle environmental conditions while complying with all relevant local residential or commercial building codes.

Weight capacity depends on the stringer configuration and engineering specifications of the system. For single stringer stairs, the heavy-duty central beam support system is engineered to handle 300 lbs per tread. Double stringer staircases are engineered to accommodate high-traffic areas and heavy load requirements for both residential and commercial applications, maintaining stability and code compliance across standard and wide stair designs.

Stair width depends on the stringer configuration chosen for your space. Single stringer straight stairs can be built up to 42 inches in width without requiring additional support structures. For wider staircase layouts exceeding 48 inches—such as 60-inch wide stairs—a double stringer system with parallel support members is recommended to provide optimal structural integrity, balance, and load distribution.
