Bridge
High-strength fasteners for bridges
Fasteners in Bridge Structures
Bridges are complex systems composed of multiple materials such as steel structures, concrete, and cables.
Fasteners perform critical functions in bridges for connection, load-bearing, and protection:
- Structural connections: securely connecting steel beams, columns, and supports;
- Load-bearing and shear resistance: withstanding bridge deck loads and wind-induced vibrations;
- Corrosion protection: protecting against humidity, salt spray, and temperature fluctuations.
