Open Riser Stair

A stair that has no physical riser members.

A highly finish and technical stair using mainly cement and marble based treads with no risers.

There are many fine examples of indoor open stairs like this that have a very light and floating appearance.

A simple, cheap to make, easy to clean and maintain stair. Steel channel strings and timber treads.

I have seen comments on the web that this type of stair may be unsafe due to the fact that a baby may crawl through the gap between the treads. If the stairs are built to code there is no problem in that respect.

I built the stair above a few years ago. We paid particular attention to our regulation stating that a ball of 125mm diameter should not be able to pass between the treads or through the balustrade in any part. The treads are 45 thick and the rise is 165 or so.

In the event of the gap being greater than 125, it is a simple matter to screw a timber batten to the underside of the tread nosing to make the stair compliant.

An all steel helical stair.

The stair above has folded checker plate steel treads. The "Z" shape of the tread provides stiffness and strength and at the same time reduces the gap between treads to less than 125mm.

These open stairs without risers are particularly suited to curved stairs of all types.
