Fabricating a single stair stringer requires precision structural steel manufacturing. Heavy steel tube profiles, such as rectangular, square, or round tubing, are cut and welded with heavy-gauge riser wedges and tread mounting plates. Factory fabrication ensures proper structural integrity and adherence to load-bearing standards before components ship to site.

While traditional wooden stairs often utilize 2x10 or 2x12 dimensional lumber, mono single stringer stair systems rely on heavy-duty structural steel rather than wood. Structural steel tubing, such as 4x6, 6x6, or 6x8 steel tube sections, provides the requisite load capacity and span rigidity without requiring multiple wooden framing members.

Our mono single steel stringer stair systems feature heavy-duty center beams engineered to handle 300 lbs per tread. The structural steel tube construction and welded tread plates deliver dependable stability and meet applicable building code load requirements for both residential and commercial spaces.

Single steel stringer stairs can be custom fabricated in multiple configurations, including straight-line, L-shaped, U-shaped switchback, geometric winders, and curved layouts rotating from a few degrees up to 360 degrees. They can also be integrated directly with straight or spiral stair elements.

Single stringers can be built using multiple heavy structural steel profiles, including 4x6 rectangular tube, 6x8 rectangular tube, 6x6 square tube, 6x6 square tube set on a diamond orientation, 4-inch round tube, 6-inch round tube, and tri-frame pipe designs.
