The upper structure of steel arch bridge is mainly composed of arch ring, suspension rod (or arch column), tie rod, bridge beam and other components.

• Section form: Steel box arch, steel pipe arch, steel truss arch
• Boom layout: Parallel vertical boom, inclined boom, mesh boom
• Carriageway position: Upper bearing type, middle bearing type, lower bearing type
• Arch ribs: Parallel arch ribs, basket arch ribs, butterfly arch ribs

• Simple system arch bridge: Only the arch ring is the main force component
• Combined system arch bridge: Carriageway beam and arch combination, common force

Steel arch can be designed into truss arch, box arch, or plate arch. Truss arch bridges are particularly suitable for large spans.

• Arch rib truss layout
• Arch axis configuration
• Vector span ratio
• Vault and arch foot height selection
• Boundary conditions
• Bar section form and area

The main load-bearing members that primarily bear axial pressure. Available in box, pipe, or truss type sections.

Force transfer components that transmit deck loads to arch ribs. Available as rigid (steel pipe/section) or flexible (high-strength wire) configurations.

Bears the thrust of non-thrust arches through axial tension. Available in rigid or flexible configurations.

Ensures transverse stiffness and stability, with common forms including one-word, K-shaped, X-shaped, and meter-shaped braces.

• Road Bridges: For spanning rivers, valleys, and other obstacles
• Pedestrian Bridges: Safe passages with aesthetic appeal
• Railway Bridges: For spans exceeding other bridge type capabilities

• Distinctive arch-shaped design
• Steel construction for durability
• Versatile deck configurations
• Customizable surface finishes
• Adaptable to various loading requirements
