TK450 Delta Bridge

The bridge uses standardized, interchangeable steel components with full highway loading capability to provide a permanent, steel bridging solution which can be configured for clear spans of up to 81 meters. It can also be supplied in multiple spans, supported on intermediate piers, meaning that there is no limitation to the length it can bridge.

It is precision-engineered and therefore quickly and easily installed, with minimal construction equipment. This offers significant advantages over more traditional solutions, such as concrete bridges, which require skilled labour and heavy-duty equipment, and necessitate long lead-times together with major on-site construction work

The benefits offered by the Delta" therefore ensure quick. safe and efficient project delivery, reduce project risk, and deliver substantial savings, making it the preferred long-span solution of choice for customers all over the world

The top chord and the bottom chord of the main girder are modularized unit with H-shape section; The web member system is also modularized unit with K-shape.
