Monumental Stairs That Bring Architectual Vision to Life
From concept to installation, McGregor turns bold design intent into precisely built, showpiece steel stairs.
A Century of Craftsmanship.
A Legacy in Steel.
Since 1919, McGregor has partnered with architects and builders to create custom steel stairs that define spaces. Our vertically integrated approach, from design assist to detailing, fabrication, and erection, delivers unmatched control, quality, and consistency.
Design Assist That Brings Your Vision to Reality
McGregor’s Design Assist process bridges the gap between creative vision and constructible detail. It starts with collaboration – our team works directly with architects to translate creative ideas into buildable details that preserve design intent. Tekla modeling brings those discussions to life in 3D, showing how every curve, landing, and connection will come together. By engaging early, we help refine details, uncover efficiencies, and ensure what’s drawn on paper can be built exactly as envisioned.
Fabricated with Precision. Installed with Pride.
Every monumental stair is fabricated in our Pennsylvania facility using CNC technology and precision jigs to ensure perfect alignment and fit. Our field crews work hand-in-hand with CMs and other trades to execute seamless installation, keeping projects on schedule, on budget, and true to the architect’s design.
