Product Description

Introducing our state-of-the-art Bridge Expansion Joint systems, including both Modular Expansion Joint designs, crafted to perfection.

Our Haider expansion joints collection boasts a versatile selection, featuring the single rail type and the advanced modular type for your construction needs.

Our cutting-edge expansion joint system is meticulously designed to facilitate bridge deck movements effortlessly while preserving a flawlessly smooth and watertight riding surface.

Engineered for unparalleled durability, our joints are built to outlast the bridge deck they serve. With a robust steel support system, they expertly balance traffic impact resilience with the flexibility to adapt to various deck movements. The system accommodates a movement range spanning from 80 to 640 mm.

Our expansion joint system stands out as the technically and economically supreme choice within its movement range, making it the ideal solution for the vast majority of bridges.

Featuring a straightforward yet efficient structure, rubber is strategically positioned between steel rails to adeptly manage expansion and contraction from temperature variations or bridge impact loads, thanks to the responsive nature of the rubber.

Enhanced with a support box bearing, our product transforms the conventional assembled rail into a monolithic rail, significantly boosting durability and stability against cumulative fatigue while offering outstanding waterproofing capabilities.
