MODEX® Flex stairs – maximum safety during ascent

The new MODEX FLEX stairs provide safe temporary height access in construction, in public buildings and at events – wherever high requirements are placed on the load-bearing capacity or the width of the passage.

New standards in terms of safety and flexibility

The MODEX FLEX stairs allow temporary access to heights in accordance with all legal requirements. They meet the requirements of the latest amended "Technische Regeln für Betriebssicherheit" (Technical Rules for Operational Safety) (TRBS) 2121-1 for  the safe assembly of scaffolding as well as the high-rise building ordinance, the event ordinance and the guidelines for escape routes. The system meets all geometric requirements according to DIN EN 18065 for public stairs.

Extremely flexible

The steps are created from system decks. It therefore has a variable width. A maximum of three climbing heights can be reached, whereby an exit grid of 50 cm is possible. The high load capacity of MODEX FLEX stairs of 7.5 kN/m² (for events) enable safe height access even with increased requirements.

Safe assembly

The construction of MODEX FLEX stairs is symmetrical because it has no right or left stringer. If necessary, a double flight of stairs can be realized. The guardrail of the MODEX FLEX stairs acts both as an anti-lift safety device for the scaffold flooring and as a diagonal guard rail. The new stairs are compatible with all scaffold flooring from BOSTA® and MODEX.
