STM Staircase

The STM is a prefabricated steel staircase system designed for efficient on-site installation with minimal disruption to landscape or structure. Fabricated in Corten steel, its weathering surface and robust profile give it a strong architectural presence that suits both natural and built environments. Each unit is designed to slot together using self-tightening wedges that draw the stair risers into position without the need for on-site welding. The same system secures the edging on either side, ensuring alignment and structural clarity.

The STM Staircase can be installed as a straight or curved configuration and adapted to suit the gradient of almost any outdoor setting. It arrives in prefabricated components that reduce labour, limit site works, and support a faster, cleaner installation process. While designed for minimal intervention, it is important to note that each site is unique and may require preparatory works before installation.
