DESCRIPTON OF THE RUBBER EXPENSION 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.
