OUR LEAD RUBBER BEARINGS ON EXHIBITION
Bridge bearings and expansion joint are important parts of whole bridge components, but the amount money that spent on bridge bearing and expansion joint is only 2-3.5%, it is absolutely a wise choice to evaluate it within the whole project to prevent failed choice bringing unnecessary costs.
