Permanent steel truss bridges are structural systems that combine beam and arch principles, featuring integrated upper beam structures and pressure-bearing lower columns. The rigid connection between beam and column provides exceptional load distribution and structural integrity.

• Upper Bearing Steel Truss Bridge: Bridge deck located in the upper part of the main truss
• Lower Bearing Steel Truss Bridge: Bridge deck located in the lower part of the main truss

• Main Girder: Primary load-bearing structure composed of upper chord, lower chord, and belly rods
• Bracing: Longitudinal and horizontal connections providing structural stability
• Bridge Deck System: Longitudinal beams and cross beams for load distribution
• Bridge Floor: Surface for vehicles and pedestrian traffic

• Triangular Truss: Simple structure with fixed design, easy installation and manufacturing
• Diagonal Bar Truss: Multiple bar specifications with large internal forces
• K-Shaped Truss: Shear force distributed across two diagonal rods, suitable for mounting/dismounting
• Double-Vented Bar Truss: Optimized for large spans with enhanced buckling stability

• Large span capability up to 300 meters
• High strength-to-weight ratio for efficient material usage
• Rapid construction with off-site fabrication
• Versatile applications for highway, road, and pedestrian bridges
• Customizable designs to meet specific project requirements
• Durable construction with international quality certifications
