Our company primarily handles "ductile iron pipes," which are used for distribution pipes when laying water supply lines. Recent technological innovations have led to the emergence of seismic-resistant pipes with strong structures against earthquakes. The NS and GX types of seismic-resistant water pipes have become mainstream, replacing the conventional K and T types. Additionally, we offer a variety of materials related to water supply and drainage, including various fittings, thrust rings, bolts and nuts, rubber rings, steel pipes, stainless steel pipes, vinyl pipes, polyethylene pipes, as well as shut-off valves, fire hydrants, repair valves, iron covers, valve boxes, and expansion joints. 【Products We Handle】 ■ Pipes ■ Fittings ■ Valves ■ Others *For more details, please download the PDF or feel free to contact us.
