Trusted piping solutions since 1985.

PT. Radema Graha Sarana was established in 1985, beginning with a focus on the gas piping industry. Over the decades we have built deep expertise across a wide range of piping projects—main pipelines, branch pipelines, and installation pipelines of various diameters and operating conditions.

Our projects span the industrial, commercial, and residential sectors. Industries such as metal smelting, automotive, chemical processing, electrical, and CNG have entrusted their piping installations to us—and today we continue expanding into water pipeline projects, from new network installations and relocations to SPAM (Drinking Water Supply System) projects.

Beyond our technical experience, we are committed to high-quality workmanship, reliable after-sales service, and professional support that builds long-term trust with every client.
