Indonesia's rapid urbanization and government-led infrastructure investments are creating unprecedented demand for high-performance thermite welding solutions across multiple sectors.
Indonesia's National Railway Development Plan targets over 3,000 km of new rail lines by 2030 โ creating massive demand for thermite welding consumables, equipment, and on-site technical services across Java, Sumatra, Kalimantan, and beyond.
Jakarta's MRT and LRT networks are undergoing rapid expansion under the National Capital Relocation plan. Phase 2 and Phase 3 MRT extensions, the LRT Jabodebek system, and new city rail corridors in Surabaya and Bandung all require thousands of thermite-welded rail joints annually. The confined construction environments and tight project timelines make aluminothermic welding the preferred method for Indonesian urban transit contractors.
As the world's largest archipelago nation, Indonesia relies heavily on its seaports โ including Tanjung Priok (Jakarta), Tanjung Perak (Surabaya), and Belawan (Medan). Crane rails at these facilities require robust, seamless weld joints to handle continuous heavy loads. Thermite welding provides the metallurgical integrity needed to maintain uptime in Indonesia's high-throughput port operations and industrial logistics parks.
Indonesia is one of the world's top producers of coal, nickel, and bauxite. Mining companies in Kalimantan, Sulawesi, and Papua operate dedicated haul rail systems that require frequent maintenance welding. The extreme weight loads and abrasive operating conditions in mining environments demand thermite weld quality that meets international rail standards โ an area where RMTS products consistently excel.
PT KAI (Kereta Api Indonesia) is actively modernizing its existing mainline network while developing new intercity corridors. The Trans-Sumatra Railway project and Java freight rail upgrades involve extensive track relaying and joint welding work. RMTS's thermite welding materials have been validated for use with Indonesian standard rail profiles, ensuring compatibility with both domestic and imported rail steel grades.
Key trends shaping the thermite welding market across Indonesia's infrastructure and industrial sectors through 2030.
Indonesia's National Medium-Term Development Plan (RPJMN) allocates trillions of rupiah to railway and port infrastructure. Projects like the Whoosh high-speed rail (JakartaโBandung), Trans-Sumatra Railway, and new LRT corridors are directly increasing the volume of thermite welding work required, creating a sustained multi-year demand cycle for welding consumables and services.
Indonesia's green infrastructure agenda is accelerating the shift from traditional arc welding to thermite (aluminothermic) welding for rail joints. Thermite welding produces a single-pour, jointless connection with minimal environmental footprint compared to electric arc methods, aligning with Indonesia's carbon reduction commitments under the Paris Agreement.
The Belt and Road Initiative has deepened ChinaโIndonesia industrial cooperation, making Chinese thermite welding manufacturers like RMTS natural partners for Indonesian rail projects. Competitive pricing, technical compatibility, and proven track records on regional projects (including Jakarta MRT) give Chinese suppliers a strong position in Indonesia's procurement market.
As Indonesia's rail sector expands, there is an increasing need to upskill local welding technicians. International suppliers that offer on-site training programs โ as RMTS does โ have a significant competitive advantage. Indonesian project managers increasingly prioritize suppliers who can provide knowledge transfer alongside product supply, ensuring long-term operational independence.
Indonesian rail authorities and EPC contractors are increasingly requesting thermite welding materials customized to local rail profiles and tropical climate conditions. RMTS's OEM capabilities allow us to tailor welding powder compositions, mould geometries, and kit configurations specifically for Indonesian project specifications, reducing waste and improving weld quality in the field.

Whether in high-speed rail, urban transit systems, or conventional rail lines, RMTS offers its thermit welding materials and services to ensure the integrity and safety of rail infrastructure.
Furthermore, RMTS maintains partnerships with research institutions, universities, and industry experts in China. These collaborations enable RMTS to continuously strengthen its R&D capabilities in thermit welding technologies, resulting in products optimized for tropical climate performance.
Real-world project experience delivering measurable results for rail operators, transit authorities, and industrial clients.
As part of the Phase 2 expansion of Jakarta's Mass Rapid Transit (MRT) system, RMTS was contracted to provide aluminothermic welding solutions for the new underground and elevated tracks. The project involved welding 600 rail joints across a 12-kilometer stretch, connecting key areas of the city to reduce traffic congestion.
Our team worked closely with PT MRT Jakarta to ensure the welds met international safety standards. The project was completed on time, and the new line has been operating smoothly since its launch. Jakarta MRT officials highlighted the durability of the welds, which have withstood the high frequency of train movements and tropical weather conditions.
Challenge: The client faced the challenge of welding materials for T62 and P65 rails. The welding process needed to meet the rigorous standards set by the railway authorities, ensuring optimal track performance, longevity, and safety.
Solution: Our team collaborated closely with the client, thoroughly understanding their specific requirements. We provided high-quality thermit welding materials, including welding kits, tailored to suit the T62 and P65 steel rail specifications.
