Description
Description

Nosing stair risers with closed stringers embody a traditional, functional staircase design while enhancing comfort and safety. The risers feature a "nosing" – a protrusion on the tread edge, extending slightly over the riser beneath. This not only adds an architectural detail but also increases foot grip, reducing the chance of slips. Closed stringers run along both sides, enclosing the treads and risers, offering robust support and a clean, seamless look. This design amalgamates practicality, comfort, and classic style, making it suitable for a variety of architectural aesthetics, whether traditional or modern.
