Pressure-locked stair treads –

Floor gratings


Stair treads consist of a pressure-locked grating furnished with a non-slip stepping edge (nosing) that makes walking up/down the stairs comfortable and safe. Side plates with holes make assembly to the support structure (stringers) easy. In combination with our pressure-locked gratings they will meet even the most demanding requirements.  

Stair treads are made according to DIN 24531.1 standard
