Alternating Tread Stairs

Alternating tread stairs are preferred in many industrial and commercial applications by achieving vertical access with a shorter horizontal span than traditional stairs and greater functionality than traditional ladders. Duvinage custom designs and fabricates alternating tread stairs to the highest industry standards. Available in steel, stainless steel, and aluminum, with finish options in primer or air-dry paint, powder coated paint, or galvanized. Select from custom and standard sizes for a robust, space saving solution to your vertical access needs.

Ideal for mezzanines, roofs, roof hatches, production lines, parapets, process equipment access, catwalks, storage tanks, emergency egress, and loading docks.
