Description of Rubber Bridge Expansion Joint:
     Rubber Bridge Expansion Joint system comprises of 8 NO. Standard models designed to accommodate movement up to 330mm by shear deformation of the elastomer between the steel components. Each model of our Rubber Bridge Expansion Joint incorporates steel angles designed to be bolted to the structural deck and a steel bridging plate system which spans the open joint gap. The elastomer case is highly resistant to oils, solvent spillage and the trafficked surface includes an anti-skid pattern for safety having a rubber to rubber coefficient of static friction of 0.69. Each model of our Rubber Bridge Expansion Joint is specifically designed to accommodate horizontal and skew movement and will also accommodate vertical movement due to rotation of up to 6mm.

Features of Rubber Bridge Expansion Joint:

 1, small size, light weight, good flexibility, easy installation and maintenance.

 2, the installation can produce lateral, axial, angular displacement, pipe barrier from the heart, not parallel flange limits.

 3, working to reduce structure-borne noise and vibration absorption capacity.  

Application of Rubber Bridge Expansion Joint:
    Rubber Bridge Expansion Joint is used in Highway bridge decks, Service ramps, Multi- storey car parks and so on. Rubber Bridge Expansion Joint is used to prevent buildings or bridges appear some cracks because of climate change.
