Pedestrian bridges allow designers to create unique sculptural structures which often become focal points and tourist attractions in addition to their primary purpose.  The most creative designs allow engineers to explore new materials and experiment with new design concepts. Some of the world’s most spectacular recent pedestrian bridges have used duplex and austenitic stainless steels in locations around the world.

With strength levels higher than carbon steel structural sections (36 or 50 ksi (250 or 450 MPa)), duplex stainless steels have become increasingly popular as a means to reduce structural section sizes and bridge weight.

In November 2015, two spectacular arched duplex stainless steel bridges were announced for Fort York Park in Toronto. They are Canada’s first stainless steel bridges and were designed by Pedelta.

In the Middle East, the Lusail Development Project in Qatar includes two intertwined (656 feet or 200 meter) 2205 duplex stainless steel pedestrian bridges designed by Safdie Rabines Architects and T. Y. Lin.

In the US, the AISC Steel Design Code 27: Structural Stainless Steel was released in 2013 and also covers larger structural sections. China is expected to add stainless steel to its structural design codes in the near future. See our structural design resources for more information.

IMOA (International Molybdenum Association) is a non-profit industry association, which provides technical information to assist with successful specification of molybdenum-containing materials. Molybdenum is an element. When it is added to stainless steel, molybdenum increases its resistance to corrosion caused by deicing salts, coastal atmosphere and pollution.
