Granor Steel Finger Expansion Joints Series SFEJ

The Granor ETIC® SFEJ series Steel Finger joints are robust Bridge deck expansion joints that accommodate larger movements ranging from 150mm up to 600mm total capacity. These joints should be adopted where the structure gap will open beyond 85mm ULS, in which case the use of a stripseal type single seal element joint will transgress the maximum 85mm open gap criterion nominated in

The teeth are also wider compared to the fingers of the finger plate type expansion joints. The finger plates are supported on one side, the tips remaining free as cantilevers and as such the thickness of the finger plate is more. Expansion gaps in such joints are also more. This type of expansion joints are used in large span steel bridges.
