PT Diansakti Sejahtera was established by Mr. Eddy Hartono Djafar, originating from CV Diansakti Sentosa in the 1980s as a supplier of hot rolled carbon steel materials for the marine industry. Our initial portfolio included steel plates, steel extrusions, and carbon steel fittings widely used in shipbuilding and marine equipment applications.

During the 1990s, the company strengthened its specialization in marine equipment, leveraging material compatibility and industry expertise. Responding to the growing demand for marine aluminium construction in the early 2000s, we expanded into marine-grade aluminium and aluminium extrusions for lightweight and corrosion-resistant applications.

In 2018, we further enhanced our capabilities by stocking certified high-quality aluminium and selected non-ferrous metals such as CuNi 90/10, commonly used in marine piping and heat exchange systems. This strategic move addressed the limited availability of knowledgeable and reliable stockists in Indonesia. All materials supplied are supported by proper certification and comply with IACS standards where required, ensuring suitability for critical marine applications.
