■Core Competence

Kurodite has the largest market share (40%) in cast bolts and nuts for waterworks through the development of material with high-corrosion resistance and we are the top company having a consistent system for production and sale. Kurodite has the capacity to produce pressed rings used in joint parts for waterworks, both small and large diameters. Especially for products of over 1,000 mm diameter, we are receiving recognition as the “only-one” company.
Water systems are our lifeline and require being fully functional in times of disasters such as earthquakes. Kurodite has been advancing development with the focus on users and has been providing unique products including corrosion resistance alloy bolts (SA, FSA), pipe stopper bolts, flexible tubes, air-back type waterproof elements, BB units, and NS holding tools. In addition, Takahama Factory is equipped with detailed evaluation systems to examine developed products. Such systems include structure-testing machines, pipeline testing devices, and large-scale testing facilities to examine connected pipes.
