In the foreground you can see the concept of an open tread. The stringer is cut in a rise (vertical) and run (horizontal) pattern, creating a saw tooth look. This open tread stairs will have a support wall under the stringer. The background stringer is a closed tread stringer and will also have a support wall. Rail and balusters are placed on top of the tread end creating a typical open tread stair. |
