Precast concrete spiral stairs

The versatility of precast concrete, together with innovative engineering and finishing processes, allows us to create bespoke spiral staircases that are both visually pleasing and exceptionally resilient.

Utilising leading Northern European manufacturing technology, our palletised formwork and precast shuttering system ensures the finish is of the highest quality.

However innovative your design, with our precast spiral staircases there is no need to compromise on aesthetics versus durability, or on elegance versus functionality.

Precast concrete helical stairs

We work closely with architects, engineers, and designers across the country to produce the stunning, durable precast spiral staircase installations we’re famous for. All our precast helical concrete stairs are made completely bespoke for your project or design.


Precast concrete is well known for its tough, reliable properties. Concrete stairs are resistant to erosion from foot traffic and resistant to damage from flooding or fire. Available in succession or in single units, they can be installed quickly and efficiently by our engineers at most stages of the construction process, but not once the roof has been installed.

Cantilever stairs

Built into a supporting wall during construction, these individual step units (weighing in at around 130kg per step), are supported vertically along their front edge by the step below and the wall into which one end provides torsional restraint. Allowing for a thinner overall waist thickness, this slender cantilever design provides greater aesthetics over traditional methods and is a firm favourite for those with a keen eye for detail.

Why choose our custom precast stairs for your project?

Our materials and methods result in luxurious and durable concrete spiral stairs that will stand the test of time. With precast helical concrete stairs from Milbank, there is no need to compromise between aesthetic appeal and structural integrity; there is no need to sacrifice elegance for functionality.
