Doshin Rubber Engineering

What Doshin Rubber Engineering does

Doshin Rubber Engineering, operating as Doshin Rubber Products (M) Sdn. Bhd. (registration 198401001871 (114386-H)), is a Malaysian manufacturer of engineered rubber products for civil infrastructure, established in 1978 in Klang, Selangor and operating as a subsidiary of the Kossan Group. The company designs, manufactures, and supplies seismic isolators (High Damping Rubber Bearings, Ultra High Damping Rubber Bearings, Lead Rubber Bearings, Friction Pendulum Bearings), structural bearings (elastomeric, mechanical pot, spherical), expansion joints (elastomeric, 3-DOF modular, finger), marine fenders, rail and transit products, and mining rubber products. Its customer base spans infrastructure project contractors, engineering consultants, and government agencies across at least 18 countries including Malaysia, Indonesia, Vietnam, the Philippines, Chile, Peru, Australia, New Zealand, China, the Middle East, Thailand, Myanmar, Singapore, Sri Lanka, Colombia, and Portugal.

Doshin's technical moat rests on over 30 years of proprietary rubber compound R&D, a unique 2000-ton hydraulic press housed in a 3200mm diameter autoclave described as unique in the world for engineered rubber production, and an ISO/IEC 17025 accredited E-Lab Testing & Research Center testing to BS5400, BS EN 1337, AS 5100.4, BS EN 15129, and AASHTO M251 standards. Differentiated products include Ultra High Damping Rubber Bearings achieving >12% damping ratio using only natural rubber (equivalent to Lead Rubber Bearings) and electrical-insulated rubber for Alstom's APS3 ground-level tram power supply and SRS electric bus charging systems.

The company operates an enterprise field sales model, supplying custom-engineered products directly to project specifications under multi-year project-based contracts. Pricing is determined per project based on specifications, order quantity, and technical requirements with no public pricing. Revenue is generated through two streams: engineered rubber products manufacturing and ISO/IEC 17025 accredited testing and R&D services. Marquee project references include the Penang Second Bridge, KVMRT Line 2, LRT Malaysia, LRT3, Jorge Chavez International Airport (Peru), Hospital Del Salvador and Claudio Vicuna Hospital (Chile), Dong Thap Bridge (Vietnam), University Indonesia Hospital, and Wika Tower (Indonesia), plus a core strategic partnership with Alstom for global tram power systems.

Mageba is the most directly comparable global peer, offering the same core product families (elastomeric, pot, spherical bearings and modular expansion joints) specified to BS EN 1337 and AASHTO standards.
• Maurer SE: German manufacturer of structural protection systems including laminated elastomeric bearings, pot bearings, expansion joints, and seismic isolators. Maurer competes directly with Doshin on international bridge and infrastructure projects, particularly in Europe and Asia.
• Earthquake Protection Systems (EPS): US-based specialist in seismic isolation devices including Friction Pendulum Bearings and laminated rubber bearings. Direct peer in the niche of civil-structure seismic protection, particularly for hospitals and critical facilities.
• Kawakin Holdings (Kawakin Core-Tech): Japanese specialist in seismic isolation rubber bearings (HDRB, LRB) and structural bearings, with strong presence in Asia. A direct competitor in the Asia-Pacific seismic isolation market alongside Doshin.
• Freyssinet (Vinci Group): France-based specialist in construction engineering, including structural bearings, expansion joints, and seismic devices. Competes head-to-head with Doshin on major bridge and infrastructure tenders globally and is a major supplier of post-tensioning and seismic protection systems.
