The Everest steel spiral staircase embodies the perfect balance between style, strength, and space optimization. Designed to fit residential interiors where every square foot counts, it combines a clean, modern design with solid structure and smooth vertical flow between floors.
Its black steel helical stringer (E56 – E67) and matching vertical railing ensure exceptional stability and safety while allowing natural light to flow through the space. The light wood steps add warmth and create a refined contrast between the black metal frame and the natural wood texture, giving the staircase a modern yet inviting character.

In this residential project, Prestige Metal participated in the design and fabrication of a custom Everest steel spiral staircase (E56 – E67), in collaboration with Bourque Escaliers, a Canadian-based company renowned for its craftsmanship and high-quality stair designs.
The goal was to create a compact, functional, and elegant staircase perfectly suited to a smaller residential layout.
The matte black steel helical stringer supports each light wood step with precision, while the vertical railing enhances both the sense of height and the visual harmony between metal and wood. This play of contrasting materials highlights the project’s modern aesthetic and technical precision.
The result is a refined, durable, and contemporary staircase that showcases the beauty of materials and the excellence of Canadian design.
Since 1997, Prestige Metal has been designing and manufacturing steel stringers, balusters, posts, and custom interior staircase components in Canada for both residential and commercial projects.
Known for its superior quality craftsmanship and engineering precision, the company collaborates with architects, designers, and contractors across Canada to create unique staircases that are modern, durable, and compliant with the Canadian Building Code and the International Building Code (IBC).
