Modular build based on anodized aluminum profiles

JOMY benefits from specially designed profiles. They allow for a "meccano-style" assembly system that will fit perfectly in your specific situation and required measurements.
Wether the stairs are used for fire evacuation or access to heights, applicable standards are essential to our engineers.

Multiple layout possibilities

Depending on the type of building, its use and the main purpose of the staircase, our engineers will work with different configurations - inline, crossed, square or a combination - and supporting structures - self-supporting or hanging-from the wall. Examples:

Inline stairs for fire evacuation, hanging from the wall.
