 Description of Hot-sale Road Expansion Joint:   
         Hot-sale Road 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  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 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 Hot-sale Road Expansion Joint:
       As one of the company’s main series of products, our expansion joint stands most competitive position
in the domestic & abroad markets of same industry by its convenient installation, stable running, waterproof,
dustproof, little noise, light weight, and low cost and other features.

        Hot-sale Road Expansion Joint is the flexible transformation when using high elasticity to adapt the change of temperature. And our  Hot-sale Road 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  Hot-sale Road Expansion Joint:
        Hot-sale Road Expansion Joint is used in Highway bridge decks, Service ramps, Multi- storey car parks and so on.  
Hot-sale Road Expansion Joint is used to prevent buildings or bridges appear some cracks because of  climate change.
