Product Description

Product Description

Finger expansion joints are designed for longitudinal movement capacity up to 400 mm, even more. Their steel edge profiles are welded with strong anchor loops for the durable concrete connection to the bridge structure. Finger plates are fixed with steel edge profile by high strength bolts. This connection method ensures the quick replacement of any finger plate on site. The finger plates can reduce the noise emission and increase driving comfort when traffic passes. A drainage channel is firmed connected with the two steel edge profiles, which ensures the expansion joint is watertight.
finger expansion joints are suitable for use in bridges with heavy traffic loading and in case that the block-out dimensions are limited for modular expansion joint, but suitable for finger joint.
