Industeel supplied 300 tons of UR TM 2205 Duplex stainless steel plates (15 to 35 mm thick) from its mills of Charleroi and Le Creusot with a very stringent surface quality requirement to the steel constructor Mariani Metal Fabricators.
This pesdestrian and cycle bridge of Pedelta includes a unique design consisting of two tied Duplex stainless steel network arch bridges to cross two railway corridors. The two arches tilt in opposite direction, and the overall layout resembles a Yin & Yang shape to emphasize both contrast and continuity, expressing a modern, understated and elegant aesthetic. The innovative bridges are based on the company’s aesthetic philosophy of “Complex Simplicity”.
The proposed design in stainless steel was awarded within a design and build project context competing against other bridge alternatives using carbon steel.
The design has been driven by utilizing less material and energy, providing an extended life span and easy maintenance even if the initial cost is slightly higher. The initial higher construction cost of stainless steel is offset by the extended lifecycle of bridges that are more corrosion resistant, require low maintenance and last longer, which is reducing the overall cost of ownership. This represents a net advantage for the Owner, in addition to improving safety and long-term durability.
