The Z Tread Range of spiral stairs

Closed Treads and Risers

The Z tread offers an alternative, closed riser design, a very substantial stair that can be used as a partition or to divide a room. The treads can be covered in almost any floor covering. The stepped appearance of the top of the tread is mimicked underneath adding to the style of the stair. The closed tread is great for people who want a more solid look to their stairs. The closed riser is also required for Commerical applications. As such the Z tread series of stairs can be made in diameters as larger as 3 meters

Tread Options

The Z Tread

The closed riser offers an increased sense of safety and security. It is often required for Commercial jobs but is popular in residential jobs too. It is especially popular on large-diameter stairs where toe room isn’t a concern and where the closed risers and stepped underside offer a distinctive look.
