Expansion joints are made of elastic rubber and steel plates for Bridges with a displacement from 40mm to 330mm. Various length, width and thickness can be produced as project requirements.
Finger expansion joints are designed movements 80 mm to 1,200 mm which composed by steel finger plates, CR sheet, anchor bolts and other components. The rubber sheet is placed on the retractable steel, and anchor bolts help to fix the whole structure.

Modular highway bridge concrete expansion joints are manufactured to match perfectly the structure’s profile, enabling surface water to remain on the deck so that it can be directed toward the drainage systems designed for this purpose.

What is bridge expansion joints
Bridge expansion joints are designed to allow for continuous traffic between structures while accommodating movement, shrinkage, and temperature variations on reinforced and prestressed concrete, composite, and steel structures.
Finger Expansion Joint Designed For Any Application
The simplistic design of Finger Expansion Joint, which have no moving parts, can accommodate any bridge deck expansion joint movement. These expansion joints are comprised of pairs of independent elements with parallel steel teeth. The tooth joints support vehicles as they travel across expansion joint openings.
Transflex Expansion Joint Effect
High performance lastomeric expansion joint allowing absorption of deck movements and water evacuation, bearing the traffic loads and avoiding the traffic disturbances. The continuous rubber surface (with or without metal plates) ensures water tightness at the joint level, without any need for additional water removal devices before surface level. Thus, rubber expansion joints can be installed on the thinnest structural slabs and bridge decks.
