Structural Systems We Use in Richmond Hill Projects
- Double-Stringer (Side-Plate): Two steel plates run along both sides of the treads, anchored to floor framing above and below. This was the system used in the project above and is our most common solution for multi-storey homes since it adapts well to varying floor conditions at each level.
- Mono-Stringer (Cantilever): A single steel spine with treads cantilevered off one side. Requires a structural wall or beam on that side and produces the most minimal visual result.
- Hidden Spine: The steel structure is enclosed within a finished wall, leaving only the treads visible. Best suited to renovations where the wall can be opened and rebuilt around the stair structure.
Ontario Building Code Requirements
All floating stair installations in Richmond Hill fall under the Ontario Building Code, Division B, Part 9 for residential construction. Key figures that affect design:
- Minimum tread depth: 235 mm
- Maximum riser height: 200 mm
- Minimum stair width: 860 mm clear of handrails
- Guard height: 865 mm to 965 mm above tread nosing
- Guard openings: no gap may allow a 100 mm sphere to pass through
We design to these figures from the first drawing and coordinate permit documentation with the City of Richmond Hill as part of our process.
