In this residential project, Prestige Metal designed and manufactured a custom-made spiral staircase based on the Everest model (E56 – E67). The installation was completed by a local contractor specializing in custom hardwood and metal projects.
The result is both functional and architectural, blending seamlessly into a warm interior space featuring a natural stone wall and wood floors. The black steel helical stringer securely supports each wood step, while the vertical balusters add a sense of structure, lightness, and modern elegance.
Designed for both modern residences and contemporary chalets, the Everest model stands out for its durability, stability, and timeless aesthetic appeal.
Since 1997, Prestige Metal has been designing and manufacturing high-quality steel stair stringers, posts, balusters, and components in Canada. Known for precision craftsmanship and long-lasting quality, the company works with architects, designers, and builders across Canada to create unique, durable, and fully code-compliant staircases.
Each staircase is built to combine aesthetic appeal, structural performance, and compliance with the Canadian Building Code and the International Building Code (IBC).
