Signature Monobeam Straight Stair Design
Built for Minimalism, Designed for Strength
The Custom Iron Standard Monobeam is one of our most requested styles for custom-designed straight staircases in the USA. It’s defined by a single center beam that gives the stair a floating appearance—sleek, minimal, and impressively strong. We’ve incorporated thoughtful adjustability into the design, giving you flexibility during installation without sacrificing performance or aesthetics.
This design is ideal for:
- Open floor plans
- Modern industrial homes
- Office environments and commercial spaces
- Retrofit projects where clean lines matter
Our Monobeam stairs are available in popular finishes like black, white, and custom powder-coated options.
