Steel Spine Staircases

Modern Design Meets Structural Strength

A steel spine staircase is more than just a functional element—it’s a bold architectural feature that adds instant sophistication to any home. At Delkon, we specialise in crafting custom steel spine staircases that seamlessly blend strength, style, and smart engineering.

What Is a Steel Spine Staircase?
A steel spine staircase features a central steel beam—often referred to as a “mono stringer”—that supports each tread from beneath. This minimalist structure creates the illusion of floating steps and delivers a clean, contemporary aesthetic that suits a wide range of interiors.

Why Choose a Steel Spine Staircase?

1. Strong and Long-Lasting

Engineered from high-grade steel, the central spine provides exceptional strength and support. It’s designed to withstand daily wear and tear, offering long-term durability without compromising on design.

2. A Statement in Style

Steel spine staircases are the go-to choice for modern and open-plan homes. The exposed central stringer and floating treads create a sense of space and elegance, making the staircase a standout feature in your home.

3. Custom Finishes to Suit Your Home

The steel spine can be powder-coated in a range of colours and finishes to match your interior palette. Paired with timber, glass, or steel balustrades and your choice of tread material—such as hardwood or engineered timber—every staircase is built to reflect your style.

4. Smart Use of Space

Thanks to their slimline design, steel spine staircases are ideal for homes that want to maximise space without sacrificing visual impact. The open construction allows more natural light to flow through the area, helping rooms feel larger and more connected.

5. Built for Precision, Loved by Builders

Our team works closely with builders and architects to ensure each steel spine staircase is tailored to exact specifications. The central beam is engineered for a precision fit, making installation efficient and stress-free.
