The existing steel finger expansion joint device accumulates alien substances in the space between each finger plate which interferes with expansion joint movement of the bridge and causes structural problems to the stability of the expansion joint device. In addition, if some alien substances do accumulate in the drainage sheet of the expansion joint devices, then they will frequently damage the drainage sheet made of rubber material and degrade the drainage function which in turn causes an excessive increase in repair and maintenance costs. We are obligated to overcome these problems.
- Alien substances accumulate between the fingers of the expansion joint to hinder the expansion joint movement of a bridge.
- Alien substances that passed through the fingers of the expansion joint accumulate in the drainage sheet and damage the drainage sheet and deteriorate the drainage function.
- To remove accumulated alien substances requires periodic cleaning. (Cost and time accrue.)
- It is made of highly durable steel material. So it has a semi-permanent life. (A shutter is made of stainless material).
- Finger prevent alien substances from entering the device are effectively blocked by debris and durable, and maintenance costs of the bridge is possible
- Excellent durability and abrasion resistance due to a top of shutter is molded as stainless.
- A shutter(high elastic rubber) has always a perfect restoration
- No periodic cleaning due to perfectly preventing alien substances.
- It is constitution continued of a finger and finger and minimizes a resonance phenomenon, thus the influence of noise occurrence and shock can be minimized.
- It is shipped as the final product from the factory. Its torque on bolts and welding qualities are great.
- Conbine preventing alien substances equipment(Shutter) with sub-finger plate.
- Deformation down at expansion joint's contraction
- Restoration at expansion joint's expansion
- Excellent durability and abrasion resistance due to a top of shutter is molded as stainless.

* 1. The above dimensions are standard dimensions. They are subject to change depending on the site conditions.
2. A curved bridge may cause the finger shape/angle to vary depending on the direction of expansion joint or rotation.
3. The leakage prevention facility in the lower area of the expansion jcint device.
