When it comes to staircases, the smallest details often carry the most weight, both literally and visually. Metal balusters for staircases offer a perfect balance of elegance and durability, and they’re becoming the go-to choice for homeowners, developers, and architects looking for clean lines and long-lasting strength.
Whether you’re planning a full staircase renovation or designing a new-build interior, choosing the right staircase metal handrail and baluster setup is key. It’s not just about looks; it’s about compliance, ease of installation, and daily usability.
Here’s what you need to know…
What Are Metal Balusters?
Metal balusters (often called metal spindles or stair spindles) are the vertical elements that connect a handrail to the tread or floor. They provide support, prevent falls, and contribute to the overall look and feel of the staircase.
In modern metalwork, these can be crafted in a variety of profiles (round, square, or decorative) and made from mild steel, stainless steel, or a combination of materials like timber and metal. Metal balusters are often paired with wood or steel handrails for contrast, giving a staircase a visually balanced finish.
Why Choose Metal?
Compared to timber, metal offers greater durability, consistency, and resistance to wear and tear. This makes metal a smart choice for high-traffic spaces like commercial stairwells, apartment blocks, or busy family homes.
More than that, metal balusters are versatile. They can suit minimalist designs, industrial styles, or more traditional aesthetics when combined with natural materials. If needed, you can apply wood to the handrail or base rail to soften the look while maintaining structural integrity.
Compliance and Building Codes
When installing metal balusters and handrails, compliance with building codes is essential. In the UK, handrails must typically be between 900 mm and 1000 mm high on staircases. Balusters must be installed so that no gap exceeds 100 mm in width.
At Smart Steels, we fabricate balusters and staircase metal handrails to precise specifications. Every spindle is placed with code compliance in mind. Whether you’re working on a residential new build or a commercial retrofit, we ensure your staircase meets the highest standard of safety and performance.

Pre-Drilled or Fully Welded?
There are two main approaches to installation: pre-drilled systems or fully welded assemblies.
- Pre-drilled balusters are ideal for modular or retrofit projects. These can be fitted onto treads, stringers, or base plates quickly, with the holes set precisely in fabrication to reduce onsite guesswork.
- Fully welded balusters are more common in high-traffic or commercial environments, where strength is paramount and aesthetic joins are preferred to be seamless.
Smart Steels offers both, depending on the staircase design and installation method. We’ll guide you through the options during the planning stage.
Cleaning and Maintenance
Another advantage of metal over timber is ease of maintenance. A mild detergent and soft cloth are typically all you need to keep metal balusters looking sharp. For powder-coated finishes, avoid abrasives, and for stainless steel, an occasional polish can keep fingerprints at bay.
We can also provide ongoing care advice specific to the finish and installation type used on your staircase.
Tailoring the Look
A well-designed balustrade isn’t just about safety, it can become a visual feature in its own right. Combining sleek metal spindles with timber treads or a glass infill can elevate the look of a home or workplace.
We offer a range of finishes, including:
- Satin-polished stainless steel
- Powder-coated mild steel in custom RAL colours
- Black or aged finishes for a traditional style
- Hybrid designs combining steel and hardwood
