Quality steel stairs are an essential part of any construction project where general access to multiple levels is required. We have the equipment and materials to fabricate a variety of star configurations such as spiral staircases, grate stairs, 4', 5' or double wide or pan stairs for concrete pouring. Located in New Berlin, Wisconsin Superior Structural Corporation has built a solid reputation, since 1969, by producing large, high quality steel weldments and fabrications. We employ highly qualified welders to meet our commitment of prompt delivery to our customers. Our bids are prepared per your specifications and will meet municipal codes. Our certified welders can build stairs per your specifications, including welding; grinding; and prime painting, galvanizing, or epoxy paint finishing. We can install your stairs as allowed by OSHA or hire authorized contractors.

If you are a contractor working on a government job, our WBE certification makes Superior Structural Corporation an ideal choice.

A family owned business since 1972, Superior Structural Corporation produces metal fabrications for both ornamental and structural applications. We specialize in fabricating structural steel trusses, heavy-duty steel machine bases, structural steel platforms; fabricating custom ornamental railings, pipe hand railings, trash gate frames, canopies, steel stairways, spiral staircases, mezzanines, catwalks; supplying joist and deck material; and having skilled ironworkers to erect all our projects within OSHA limits.
