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:
   Rubber Bridge Expansion Joint is the flexible transformation when using high elasticity to adapt  the change of temperature. And our Rubber Bridge Expansion Joint got good reputation of bridge engineering by its convenient installation, stable running, waterproof, dustproof, little noise,
light weight, and low cost and other features. 

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.

Construction programs of Rubber Bridge Expansion Joint:
(1) Set out and cut Rubber Bridge Expansion Joint.
(2) Excavate and clean the Rubber Bridge Expansion Joint area.
(3) Drill holes to locate the anchor bolts.
(4) Place the rebar mat and mold.
(5) Pour bottom concrete layer.
(6) Install comb-shaped steel plate.
(7) Pour side concrete.
(8) Maintenance the Rubber Bridge Expansion Joint.

Types of Rubber Bridge expansion joint:
1. Modular Rubber Bridge Expansion Joint
2. SGF series Rubber Bridge Expansion Joint
3. TST bridge elastomeric expansion joint
4. TST seamless Rubber Bridge Expansion Joint
5. Steel finger Rubber Bridge Expansion Joint
