Innovative applications of 2205 (S32205) duplex stainless steel in bridge construction are becoming increasingly common due to its superior performance characteristics. The following are examples of applications of 2205 duplex stainless steel in bridge projects:

Corrosion-resistant bridge deck: 2205 duplex stainless steel is used to manufacture bridge decks and has excellent resistance to corrosion from de-icing salts, chemicals and environmental exposure.
The high chromium and molybdenum content in 2205 stainless steel helps prevent pitting, crevice and stress corrosion and extends the life of the bridge deck.
This application is particularly beneficial in areas with harsh winters and heavy use of deicing salt, where traditional carbon steel decking is prone to accelerated aging.

Concrete bridge reinforcement: 2205 duplex stainless steel rebar is used in concrete bridge structures, particularly in areas with higher chloride exposure, such as coastal areas or waterway bridges.
The corrosion resistance of 2205 stainless steel helps prevent deterioration of the steel bars, thereby maintaining the structural integrity of concrete bridges over their longer service life.
This application has advantages in areas where traditional carbon steel reinforcements are susceptible to corrosion, leading to cracking, spalling and eventual structural failure.

Structural components of the movable bridge: 2205 duplex stainless steel is used in critical structural components of movable bridges such as trunnions, bearings and other highly stressed elements.
2205 stainless steel’s combination of high strength, toughness and corrosion resistance makes it an ideal material for these applications, where traditional carbon steel is prone to premature wear and failure.
Movable bridges, such as suspension bridges and drawbridges, often operate in harsh environments and require materials that can withstand repeated stress and corrosive conditions.

Architectural and Aesthetic Applications: 2205 duplex stainless steel is used for architectural and decorative elements in bridge designs such as railings, lighting fixtures and decorative panels.
The unique appearance and corrosion resistance of 2205 stainless steel make it an attractive choice for enhancing the visual appeal and durability of bridge structures.
The application allows bridge designers to incorporate high-performance materials that contribute to the bridge’s functionality and aesthetics.
