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.
Feature:
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.
