You guessed it; double stringer stairs use two support members for their structure. The double stringer is a floating staircase design that features the two stringers under the steps and in from the edges of the stair for a floating look.
In general, these modern and contemporary stairs are less expensive than single stringer stairs. We can use lighter material which also leads to easier shipment and installation for the average handy homeowner.
Double stringers can also be used on stairs that are wider than 48″. For example, a stair that is 60″ wide might have two 2″ x 6″ steel tube stringers set apart 32″ inches, leaving 6″ of overhang for the treads on each of the outer edges.
The modern and contemporary look is the hallmark of the double stringer staircase. It is a versatile stair that can have nearly any tread and handrail style.
Double stringers can be used in residential or commercial applications, as well as in both interior and exterior projects.
We can use any of the following materials for our floating design twin stringers:
- 2″ x 6″ Steel Tubes
- 6″ Steel Channels
- 4″ Steel Tubes
- 4″ Steel Channels
We can also make these stringers out of either aluminum or stainless steel!
The carriers for the treads are usually angle irons, flanged in toward the middle of the stair for a cleaner look from a side view of the stair.
