Product Description

Discover the versatile and innovative Bridge Expansion Joint and Modular Expansion Joint solutions, designed to seamlessly enhance your infrastructure projects.

Haider's superior expansion joints offer a comprehensive range, including both single rail type and modular type options, ensuring tailored solutions for any construction need.

Our advanced expansion joint system expertly facilitates bridge deck movements while preserving a perfectly smooth, watertight riding surface, enhancing both safety and comfort.

Engineered for endurance, our joints are crafted to outlast the bridge deck itself. Their exceptional longevity is attributed to a robust steel support system that expertly combines the strength needed to withstand traffic impacts with the flexibility required to accommodate a wide range of deck movements, ranging from 80 to 640 mm.

Technically and economically optimized, our expansion joint system is the premium choice for most bridges, providing unmatched performance and reliability within the supported movement range.

Featuring a simple yet effective structure where durable rubber is strategically positioned between steel rails, our system skillfully manages expansion and contraction due to temperature fluctuations or bridge impacts, thanks to the rubber's natural elasticity.

Enhanced with a support box bearing, our conventional rail has evolved into a monolithic masterpiece, offering superior durability and stability against cumulative fatigue, alongside excellent waterproofing capabilities.
