This mono-stringer staircase was fabricated for a residential building near the courthouse in downtown Manhattan. The design of a mono-stringer staircase is based around the single support beam running up the middle of the steps. The support beam used in this project was fabricated out of 6″ x 6″ x .5″ steel and painted gloss white for the finish. Due to the size and weight of the support beam, it had to be crane lifted on to the roof for installation. The staircase led to the rooftop deck which meant that some heavy duty welding was required when faceting the beam to the header. It’s a good thing Brett Tetro was around.
