What are floating stairs?
Of course, floating staircases don't actually float. Despite our best efforts, we can't defy gravity. But we have mastered the design and fabrication of stairs with a light and minimalist appearance. We define floating stairs as any staircase with open risers. This means that the stair treads are not connected to one another. Rather, they are connected by one or more stair stringers that run beneath the treads or along the side/sides.
How are Floating Stairs Supported?
Floating stairs can be supported using steel brackets, a central spine, or hidden stringers. These methods provide stability and support while maintaining the illusion that the treads are floating. Each approach allows for a visually stunning staircase that can be a unique addition to any space.
One popular approach is to use steel supports. These supports are typically attached to the wall or an adjacent structure and remain hidden from view. When hidden, they give the impression that the floating stair treads are floating in mid-air. The treads are then secured to the brackets, providing support and stability for those using the stairs.
Another common method, and the traditional Viewrail floating stairs, is to use a central spine that runs through the center of the staircase. This spine is made of sturdy materials like steel to support each wood tread. The treads are then attached to the spine using brackets or other hardware, creating the illusion that the stairs are floating.
Lastly, some floating staircases utilize hidden or recessed stringers. These stringers are attached to the wall or other support structures and are hidden from view behind the treads. This design choice allows the treads to appear as if they are floating while still providing a stable and secure staircase.
Are floating stairs safe?
Yes. When properly engineered and accompanied by a suitable railing system, floating staircases are safe alternatives to traditional stairs. By following the applicable building codes, safety concerns are all but alleviated. To ensure the safety of our floating staircases, Prima Industry does the following:
We control the amount of space under each tread. This can be achieved with thick treads or by adding a steel lip, cables, mesh, or glass. Through these means, we can ensure the safety of the stairs while maintaining their openness and allowing the passage of light through the stairs.
Prima Industry follows all the typical building code requirements concerning stair openings, guardrail clearances, tread rise, tread run, handrail size, etc.
Our skilled engineers closely review the structural rigidity of each staircase’s steel support system. This is important for safety, but also greatly affects how the stairs feel when you walk up or down them. Some stairs may appear simple but have complex support structures. For example, cantilevered stairs often have hardware hidden within the walls.
