As an established manufacturer (of rubber expansion joints), we design rubber expansion joints utilizing our rich experience and achievements. We specialize in designing rubber expansion joints made-to-order. To meet diverse client needs, we design individual products per request. Optimal joint structures are determined through selection of rubber material, reinforcement shape, and size, which satisfy client specifications, such as diameter, interplanar distance, pressure, and displacement. We have produced an abundance of products thus far, many of which were developed based on years of experience and know-how, and are patented products. Not only do we design using calculation and drawing tools, but we also test using scale and full-scale models.
