The surface rubber, receiving plate, and receiving base have a separated structure, so wear of the surface rubber does not expose the steel plate that causes slipping, allowing for safe operation!
The "K-330" is a diamond-free joint designed for transverse joints, installed perpendicular or diagonally to the bridge axis (the direction of vehicle travel). It is suitable for bridges with wide spans that consider displacements during earthquakes and is ideal for repairs of finger joints. Additionally, the surface rubber absorbs expansion and contraction through the elastic deformation of diamond-shaped holes, keeping the surface of the joint always flat, resulting in reduced noise during travel and a comfortable driving experience. 【Features】 ■ Protects the deck ■ Comfortable driving ■ Safe driving ■ Environmentally friendly ■ Cost-saving *For more details, please download the PDF or feel free to contact us.
