Industrial Corten Steel Spiral Staircase with Handrail

This industrial 3ds Max spiral staircase features a rusted corten steel finish and integrated metal handrails for vertical circulation. Constructed with a distinct industrial aesthetic, this spiral staircase assembly centres around a single vertical post supporting curved treads. The exterior of the stair is enclosed by a solid, sweeping corten steel panel, providing a raw, weathered appearance characteristic of oxidised metal. A separate, linear section of metal railing is included, featuring a continuous top rail and vertical balusters designed to extend along a mezzanine or landing. The proportions suggest a compact footprint, suitable for tight vertical transitions in loft-style apartments or repurposed industrial spaces where space efficiency and a bold, material-focused design language are prioritised.

Within 3ds Max, this model is managed as a set of grouped components. The treads and central column are typically organised on a dedicated layer, allowing for independent scaling or height adjustment to suit specific floor-to-floor requirements. Users should check the pivot points for the railing sections to ensure correct alignment with landing edges. Applying a high-resolution rust texture map to the corten surfaces will enhance the realism of the weathered finish when rendering in proximity to glazing or feature lighting.
