Steel used in bridge construction

Bridge steel is a steel plate specially used for erecting railway or highway bridges. It is required to have high strength, toughness, bear the load and impact of locomotive and vehicle, and have good fatigue resistance, certain low-temperature toughness and atmospheric corrosion resistance. It is used for erecting railway bridges, highway bridges, sea crossing bridges, etc. It is required to have high strength, toughness, bear the load and impact of locomotive and vehicle, and have good fatigue resistance, certain low-temperature toughness and atmospheric corrosion resistance. The steel for bolted welded bridge should also have good welding performance and low notch sensitivity.
 

Shipbuilding steel offers numerous advantages that make it the preferred material in the shipbuilding industry. Here are some key benefits:

• High load capacity
• Strong yet lightweight
• Weather-resistant and durable
• Longer lifespan, less maintenance
• Maximizes span with fewer supports
• Cost-effectiveness
• Easy to install

Carbon Structural Steel

Common Grades: A36, S235, Q235

Applicability: Smaller bridges and light-load structures like beams and supports.

High-Strength Low-Alloy Steel

Common Grades: A572 (Grades 50/60/65), S355, Q355

Applicability: Load-bearing components in medium-sized bridges (trusses, beams, columns).

Weathering Steel

Common Grades: A588, Corten A, Corten B

Applicability: Exposed bridges (highways, railways) requiring corrosion resistance.

Bridge-Specific Steel

Common Grades: Q370qC, Q370qD, Q420qD

Applicability: Large bridges, suitable for main beams and suspension structures under heavy loads.

Bridge steel is a specialized steel type used in the construction of bridges and other load-bearing infrastructure. It is selected for its high strength, durability, and resistance to environmental factors such as corrosion and extreme weather conditions, ensuring long-lasting and reliable structural performance.

Construction

Suspension bridges, cable-stayed bridges, truss bridges, arch bridges, etc.

Transportation

Railway overpasses, highway overpasses, pedestrian bridges, vehicle flyovers, etc.

Marine

Dockside crane supports, pier reinforcements, port access bridges, seawall foundations, etc.

Energy

Wind turbine supports, offshore oil rig platforms, power transmission bridges, pipeline crossings, etc.

Mining
