CIRCLE STEEL: minimalist all-steel interior spiral staircase

All-steel spiral stair for modern flats and lofts

The CIRCLE STEEL spiral staircase is designed for contemporary interiors such as studios, apartments, duplexes and lofts. Slim steel treads, a discreet central column and a curved guardrail draw a light, continuous spiral through the room. It suits projects looking for an all-steel interior staircase that is technically robust yet visually calm in the space.

Compact, space-saving spiral staircase made to measure

CIRCLE STEEL is a space-saving spiral stair that optimises limited footprints: small openings, narrow stairwells, converted attics or mezzanine access. Its compact structure, with no visible supports beneath the treads, keeps the floor area clear and lets light pass through, which is crucial when every square metre counts. Each stair is custom-made to your diameter, floor-to-floor height, rotation direction, handrail type and finish.

Why choose the CIRCLE STEEL staircase ?

Minimalist design with everyday comfort

CIRCLE STEEL combines contemporary aesthetics with practical comfort:

  • fine steel treads,

  • a smooth, rounded guardrail following the spiral,

  • no heavy volumes under the stair.

The regular geometry provides a fluid walking line even with a compact diameter. The stair allows surrounding materials – exposed concrete, timber flooring, brickwork – to stand out and reinforces the modern character of the interior.

Belgian-made steel structure for intensive use

Manufactured in Belgium in SPIRA’s workshops, CIRCLE STEEL is built from 10 mm thick steel, engineered for intensive daily use. This structure:

  • delivers excellent stability and reduced vibration,

  • offers long-term durability under frequent traffic,

  • provides a reliable all-steel spiral staircase for residential and selected professional projects.

It is a strong choice wherever robustness and low maintenance are as important as design.

Custom-made configuration tailored to your project

Every CIRCLE STEEL stair is designed to measure so it fits your building perfectly:

  • diameter tuned to the opening and room size,

  • floor-to-floor height set with precision,

  • rotation direction adapted to circulation paths,

  • choice of handrail style and paint colours.

SPIRA supports you from the early design stage to ensure the stair works with the overall layout and enhances the space rather than constraining it.

Kit delivery and installation options in Belgium

CIRCLE STEEL is supplied as a ready-to-assemble kit with a detailed installation manual. A competent DIYer can carry out the installation, following the step-by-step instructions. Alternatively, you can rely on professional installers recommended by SPIRA who are familiar with custom steel staircases. This flexibility allows you to match the installation method to your schedule and skill level.
