Company information
"Where it is said to be impossible, there lies the possibility." The fittings branded with the CK logo are filled with various trials and errors. For example, the development of new materials that are friendly to people and the Earth is one of them. In the "Piping Equipment Business" division, we have developed and commercialized fittings such as "PVC-free" and "lead-free," as well as the world's first "cadmium-free" fittings. Additionally, in the "Hot-Dip Galvanizing" division, we developed the world's only hot-dip galvanized coating, "CKe coating," which does not contain lead or cadmium, and it has also been registered in the Ministry of Land, Infrastructure, Transport and Tourism's new technology information provision system, "NETIS." We have successfully mass-produced the world's first RoHS-compliant fittings using this technology for surface coatings, continuously creating new products as a leading company in the industry. With unique technologies that are not found in other companies, we are bringing the world's first products to market. CK Metal's manufacturing spirit continues to pursue new possibilities with "environment" as its theme.
