Stuck.
It is the first product in the same industry in China. The telescopic body is made of precision cast steel, which is wear-resistant, acid and alkali corrosion resistant, has good toughness, and is not easy to break. The lower part of the seam is filled with closed-cell sound-absorbing material, and then used by our company The invented polymer nano-waterproof sealing material seals the upper seam of the expansion joint and can be firmly bonded to the expansion bodies on both sides without any adhesive, making the expansion joint an integral structure with an elastic body in the middle and free expansion. It prevents the infiltration of sewage and rainwater on the road surface and prevents sand and gravel debris from getting stuck in the joints. It completely replaces the traditional and useless rubber water-stop strips. The biggest advantage is: no water or debris will enter the expansion joints, completely eliminating water seepage. Corrodes steel components and concrete components to completely prevent expansion joints from being filled with debris.
