Helical staircases
A helical stair sweeps round without a centre post, carried entirely on its curved stringers. It is the hardest stair to make and the one people photograph.
What makes a helical different
A spiral wraps around a column; a helical is a curved flight that supports itself. The stringers are rolled to a true helix, the treads are wider and the walk is as comfortable as a straight stair. It needs more design, more steel and more skill to weld, which is why it costs more, and why it changes a hallway or an atrium completely.
Design first
Every helical starts as a full drawing, usually in 3D, so you can see the sweep, the tread shape and the balustrade before we roll a single section. We coordinate with your architect or interior designer where there is one, and with the builder over the floor opening and the landing structure.
Balustrades and finishes
Glass, bar, wire or a solid curved plate, with a timber, stainless or steel handrail. Inside, the steel is typically painted in a fine finish; outside it is galvanised and coated. Timber, stone or steel treads to suit the room.
Questions we are asked about Helical staircases
Can you make a helical staircase for outside?
Yes. External helicals in galvanised and coated steel are less common but we have made them for gardens and terraces.
How much space does a helical need?
Less than a straight stair with a landing but more than a spiral. A typical domestic helical occupies roughly two metres by three.
