One of the most popular choices for modern staircase balustrades in recent years is metal balustrades. These can take the form of modern metal panels, traditional ornate spindles, or contemporary alternating designs, often featuring rectangular or oval shapes. However, with the rise in popularity of metal balustrades, it’s important to understand the different manufacturing techniques involved. One key distinction is the difference between wrought and cast iron/steel.

Casting is a method of manufacturing where liquid metal is poured into a pre-formed mould, which, when set, creates the desired profile. The vast majority of metal spindles are cast, as this method allows for consistent designs that can be mass-produced at a lower cost. These spindles come in a range of different profiles and designs and are often pre-finished in a matte black, though some are available in other colours.

Wrought iron, on the other hand, is made through fabrication, whereby individual cast elements are combined to create more intricate designs or to achieve specific sizes and shapes. Fabricated components can still be mass-produced but are usually purchased with the intention of being reworked. Wrought iron spindles and other components are typically used for more bespoke applications, such as when odd sizes are required or when more specific designs are desired. Another advantage of wrought iron spindles, compared to cast spindles, is that they can serve both structural and aesthetic purposes. This means they can be made to support the balustrade, rather than relying on the handrail for support.

In conclusion, cast iron spindles are a good option and can be purchased cheaply and quickly, but when seeking a bespoke balustrade, it is best to consult a fabricator who can produce wrought iron spindles to meet specific needs.
