Features

It makes bridge smooth and seamless, and it's good for preserving, cleaning and moving snow.
The structure is simple, no need to have special stretch frame and anchoring steel bar. Construction is convenient and fast.
It could absorb all kinds of deformations and shaking. And its damping property is high and it's good for bridge shock absorption.
Best sealing and waterproof property and anti-acid-base and corrosion.
Low cost of construction, durable and remarkable economic benefit and social benefit.

Application

Rubber bridge expansion joints for movements of up to 60 mm apply to normal bridges. Compared with expressway, rubber bridge expansion joints are more suitable for being installed on the flyovers. They are also good choices for building new bridges.
