Product Description

Structural Rubber Materials Bridge Expansion Joint for Bridge Construction

AVIDA rubber bridge expansion joints used for up to 300mm movements, consisting of a waterproof rubber and steel plates, absorbs movements of the bridge. This system produces in factory under high temperature and pressure with rubber plates and steel plates. This is a result of the production system.


 AVIDA bridge expansion joints, guaranteed against corrosion for long-lasting solution. Rubber is strong against to surface oil, grease, oil, chemicals, resistant to UV rays, snow and salt. All expansion joints are designed to absorb movements and expansions of the structure by changing their shape. Expansion joints of different sizes are fixed to the reinforced concrete from both sides by using of suitable corrosion-resistant galvanized anchor bolts and chemical anchors to absorb elastic reactions, mechanical vibrations and other movements of the structure.
