Stairs Stair Articles. All Rights Reserved. They are not usually found in industrial settings. As the name suggests, a mono stringer staircase uses a single but heavy-duty stringer beneath the center of the treads to support the staircase. Mono stingers are normally metal and welded to each tread with a bracket. All staircases with mono stringers have open risers. Mono stair stringers are mostly used in modern homes and office buildings to achieve a contemporary look and are commonly used on spiral staircases.
A variation of the mono stair stringer is a twin stringer. In this case, two thin stringers take the place of the mono stringer. They can also be placed off center to create a more striking look. Like mono stair stringers, twin stair stringers are mostly used in contemporary residences and offices to achieve an open, modern look. A staircase with a cantilevered stringer features a single side stringer which is in mounted inside a wall and reinforced.

Two stringers are used with a double or twin stringers positioned to the outside of the stair treads. Stair stringers may need additional support depending on the length of the stair stringer and the width of the staircase. Wood stair stringers typically need additional supports between 6' and 10' lengths while metal stair stringers typically do not require additional supports. The maximum stair stringer length depends on the material used for stringer construction, the stringer size, and the stair building code requirements.
IBC stair code limits stair stringers to a maximum vertical height of 12' in a single run.

In a floating tread staircase, we either install very strong single beam stringer or two or more than two stringers. The riser present along side the tread gives extra strength to the staircase.
Thus, risers are another factor which determines the numbers of stringers. The larger number of the steps used in staircase need either stronger stringer or multiple stringers. Longer stairs with higher number of steps increase in the weight of the stairs. Therefore, the longer staircase needs more than two stringers. If the stringers are made up of thick and strong material, you need only two stringers to be installed.
On the other hand if the stringers are not thick and made up of weak material, only two stringers are not enough.
