      T-TEC LSL Stair Stringer logo

      The stair stringer is the structural component that supports the treads and risers in your staircase.

      It is responsible for the structural strength and stability of the staircase and is an integral part of the system. T-TEC LSL stair stringers are made with laminated strand lumber (LSL) and therefore provide true consistency and uniformity.
