The TKD450 Delta Steel Bridge is a half-through permanent compact panel bridge system designed for long-span applications. This modular steel bridge features standardized, interchangeable components that can be configured for clear spans ranging from 35m to 81m, with carriageway widths of 4.2m for single lane, 7.35m for double lane, and 10.5m for three lane configurations.

The bridge utilizes a precision-engineered modular design with H-shape section top and bottom chords for the main girder, complemented by K-shape web member systems. This structural configuration ensures optimal load distribution and long-term durability.

• Clear spans up to 81 meters with 4.5m module length
• Full highway load-carrying capability with BS5400 HA+20HB rating
• Pre-cambered design to eliminate dead load deflection
• Proprietary steel decking system with pre-loaded slip-resistant bolts
• Factory-applied anti-skid or site-applied asphalt surfacing options
• Steel sub-grades suitable for cold climate applications (AASHTO Zone 3)
• Seismically robust construction
• Optional 1m or 1.5m pedestrian walkways
• Vehicle parapets included as standard
• Full-scale tested for performance verification

The Delta Bridge system is designed for rapid installation with minimal construction equipment, offering significant advantages over traditional concrete bridges. The modular components enable quick, safe, and efficient project delivery while reducing project risk and construction timelines.

All bridge components are manufactured new by ISO 9001 and EN 729 accredited fabricators, ensuring international quality standards and long-term reliability.
