We do mono stringers, too

“Spiral” is in our name, but we make mono stringers, too.

A mono stringer staircase uses a single stringer that supports the center of the treads from below; most staircases use two or three supports. A single stringer is a minimalist approach that offers open space, beautiful flow of light and the feel that the stairs are floating on air, highlighting the woods treads.

Metal is hot, and a mono stringer is a great way to take advantage of this trend in your space. Because we use steel, our mono stringer stairs are very stable and an effective way to show off rich wood treads. The heavy-duty center beam is designed to support each different project.

Our mono stringers are designed in such as way as to meet building codes without using riser bars (the mechanism that would be required to prevent children from falling through the stairs). This creates a cleaner, more elegant look. Note that wood treads are required to be thicker than 3 inches (which may add expense).

Recently, we created a mono stringer for a contractor in Door County, Wisconsin, who had tapped us for a half-dozen spiral stairs in past projects. He had a very special home requiring the clean spare look of a mono stringer, and we came through.
