Thejo Engineering began life in 1986 as a services company fixing conveyor belts, and it has spent four decades turning that hands-on craft into a full-stack industrial engineering house - one that now designs, makes, and maintains the systems that keep mines, steel plants, and ports moving. The recurring pattern is backward integration: start with high-skill site services, build a sticky relationship, then supply the proprietary rubber and polyurethane products those sites consume, locking in revenue on both sides. That is how a belt-splicing shop became a global partner to some of the world’s largest miners and metal producers, with its own manufacturing plants on four continents and a research lab registered with India’s Department of Scientific and Industrial Research.
Business segments
Three engines, one flywheel - a services-led conveyor and wear-protection business that pulls through manufactured products, a mineral-processing liners business riding global mining capex, and a corrosion-protection unit that lines the tanks and pipes of heavy industry, all fed by a shared manufacturing and R&D backbone.
1. Bulk material handling: the services-and-products flywheel
Long-term maintenance contracts put Thejo’s crews inside customer plants every day, and that presence creates a captive channel for the conveyor belts, cleaners, and liners the company itself manufactures.
- Paid to keep the line running - the company operates under KPI-based O&M (operations and maintenance) contracts that provide 24×7 upkeep with manpower, spares, and tools, plus planned shutdown support, turning conveyor uptime into a recurring revenue stream.
- Products follow the service van - it designs and makes rubber and polyurethane-based belt cleaners, skirting, impact cradles, and wear liners, so the same team that maintains a transfer point can replace its consumables with Thejo’s own parts.
- Rapid-response moat - with 15 service centres and on-site presence across more than 45 locations in India alone, the company can deploy crews for emergency repairs faster than a distant equipment supplier ever could.
- Steel and mines pay the bills - the majority of the product division’s output goes to the steel sector and mines, industries where a single conveyor failure can idle a plant, making reliability worth far more than the price of a service contract.
2. Mineral processing: liners that wear so the mills don’t
Every grinding mill eventually eats its own shell unless it is lined with replaceable rubber or polyurethane wear surfaces - and Thejo supplies those liners, screens, and the installation crews to fit them, increasingly to global mining giants.
- Wear parts for the comminution circuit - the segment covers mill liners, pulp lifters, screen panels, and trommels, all made from the company’s proprietary rubber and polyurethane compounds that are formulated to withstand abrasive ore slurries.
- Installed, not just delivered - services include mill wear scanning, liner installation, and ongoing rate contracts branded as Sustainable Synergetic Solutions, so the customer buys a fully fitted lining system rather than a crate of parts.
- Global miners are knocking - in July 2026, Vale in Brazil placed the first tranche of purchase orders under a three-year supply contract for Thejo’s THOR-R and THOR-M mill liners, with the initial two complete sets valued at about USD 0.89 million.
- India’s nuclear sector is a customer too - Uranium Corporation of India awarded a rate contract for rubber lining systems on its ball and rod mills at Jaduguda and Turamdih mines, with a tentative ceiling of Rs. 3.92 crore over one year.
3. Corrosion protection: lining the tanks and pipes of heavy industry
Chemical plants, fertiliser units, and power stations attack their own equipment with acids and abrasives every day - Thejo wraps that equipment in rubber and polyurethane so it survives.
- A chemical-proof skin - the segment supplies pre-cured and un-cured rubber lining sheets, polyurethane coatings, cold and hot adhesives, and repair putties, essentially a complete kit for turning a steel vessel into a corrosion-resistant asset.
- Fabricated, lined, and commissioned - beyond materials, the company delivers rubber-lined pipes, vessels, bellows, and expansion joints as finished products, and its crews perform hot and cold lining on site, including project commissioning.
- From fertiliser to space research - end-users span chemical and fertiliser plants, power stations, and even space research and defence establishments, where a lining failure is not an option.
Manufacturing and R&D backbone
Six plants across four continents, an in-house DSIR-registered R&D centre, and a technician training school form the shared engine that supplies all three business segments with proprietary compounds, fabricated equipment, and skilled hands.
- Global manufacturing footprint - the company runs plants in Chennai (three units plus a corrosion-protection unit), Dammam, Perth, Ras Al Khaimah, Santiago, and Sao Paulo, each equipped with rubber processing machinery and in-house testing labs.
- R&D as a compounding advantage - the Chennai R&D centre has filed for 42 product patents (27 awarded) and works on everything from new wear-resistant formulations to a biodegradation process for finished rubber waste, giving Thejo compounds that competitors cannot simply copy.
- Capacity expansion underway - in August 2025, the board approved a Rs. 40 crore capex plan to add about 2,600 tonnes per annum of production capacity to the existing 3,600 tonnes, which was running at roughly 80% utilisation, targeting a wider product range and upgraded technology.
- Training its own workforce - an in-house Excellence Centre trains technicians on safety and technical skills, ensuring the onsite crews that execute service contracts meet a consistent standard across geographies.
Group structure and partners
Five overseas subsidiaries - in Australia, Saudi Arabia, the UAE, Brazil, and Chile - each act as local manufacturing or service hubs that extend Thejo’s India-developed products and service model into mining and industrial clusters worldwide.
- Thejo Australia (100% owned) - based in Perth with workshops in Kalgoorlie, Port Headland, and Bunbury, it handles belt splicing, jointing, and maintenance for the Pilbara and Goldfields mining regions, and was fully acquired from its Bridgestone joint-venture partner in stages through March 2025.
- Thejo Hatcon, Saudi Arabia (51% owned) - a Jeddah and Dammam-based joint venture focused on rubber lining and industrial services, giving Thejo a foothold inside the Kingdom’s oil-and-gas-adjacent industrial economy.
- TE Global, UAE (100% owned) - incorporated in Ras Al Khaimah in late 2023, this subsidiary sells Thejo-manufactured products and related services into the Middle East and nearby geographies, effectively a dedicated export-and-distribution arm for the region.
- Brazil and Chile (near-100% owned) - Thejo Brasil and Thejo Engineering LatinoAmerica SpA serve as warehousing, workshop, and sales outposts in South America’s mining heartland, stocking and supplying bulk handling, mineral processing, and corrosion protection materials.
