[Company strength]
As a manufacturer of manhole covers, we respond to the needs of the times by providing strength as well as beautiful designs and colors by our sophisticated casting technology. We develop manhole covers that ensure the safety and reliability of roads. We have been working on design covers since 1965, and recently use “safety and reliability” as key words. We develop iron covers that keep water inside even when the water flows backward, and that prevent two-wheeled vehicles from skidding. We also develop next-generation control taper iron covers that can be easily opened even by women and elderly people. These products meet modern needs.

[Business description]
Our company was established in 1945. As a manufacturer specializing in manholes, we have been expanding our business of design covers and manufacturing next-generation control taper iron covers. We independently develop various products to meet the needs of the times. We deal in products such as sewerage products, water supply products, and toilets for disaster situations. We are recently entering the fields of industrial machinery, and we manufacture various cast iron raw materials.
