Short answer: Bridges and infrastructure lean on structural carbon and high-strength steel for girders and decks, weathering steel for exposed spans that need little upkeep, stainless for bearings and joints, and galvanized steel for fasteners, with grade chosen for strength, fatigue life and long service.
At a Glance
Girders, Decks and Strength
Main members use weldable structural steel with predictable strength; the grades are in our Carbon Steel Supplier, data in our Perbandingan Kekuatan, limits in our Tolerances Guide and base types in our Jenis-jenis Baja Karbon.
Weathering Steel and Longevity
Exposed spans use weathering steel for a stable patina and low upkeep; the option is in our Weathering Steel Guide, corrosion care in our Corrosion Resistance Guide, the comparison in our Galvanized vs Stainless page and packing in our Export Packing Guide.
Bearings, Joints and Wear
Bearings and expansion joints need stainless for wear and corrosion; the grade pick is in our Stainless Steel Supplier dan 304 vs 316 guide, fatigue in our Fatigue Guide and welding in our Stainless Welding Guide.
Fasteners and Protection
Fasteners and trim are galvanized for rust life; the zinc base is in our Galvanized Steel Sheet dan What is Galvanized Steel, finish in our Surface Treatment Guide and the design angle in our Construction Structural Guide.
