Super Iron Foundry makes the cast-iron parts that sit beneath streets, ports and stadiums - manhole covers, drainage grates, pipe fittings and counterweights - and its products are already underfoot in more than 30 countries. Founded in 1988 and run by the second generation of the founding family, the company built its name as a pure exporter of municipal castings from India, then listed on the BSE in 2025 and began a deliberate shift from selling through overseas distributors to reaching contractors directly through its own foreign subsidiaries. That recurring pattern - earn a global reputation on the factory floor, then move closer to the end customer to capture more of the value chain - explains both where the company stands today and where it is heading next.
Business segments
A single foundry business, sold into seven end-markets and now being pushed through a direct-distribution network on three continents - one engine, multiple routes to the customer.
1. Municipal and infrastructure castings: the hidden parts that keep cities working
Every access cover, gully grate and pipe fitting the company sells is a safety-critical component built to national standards, which makes certifications and long customer relationships the real barrier to entry.
- Seven product families, one foundry - the company casts manhole covers and gully gratings for city utilities, ductile iron pipe fittings for water and sewage networks, counterweights for cranes and elevators, iron parts for farm tillage and irrigation equipment, custom components for automotive engines and brakes, rail chairs and fishplates for railway track, and helical screw piles that anchor buildings and telecom towers into the ground.
- Certifications unlock the export order book - products are made to European (EN124), American (AASHTO) and Australian (AS3996) standards, backed by ISO quality, environmental and safety certifications plus the BSI Kitemark, which is why the company can supply landmark projects such as Hamad Port, Lusail Stadium and Dubai South in the Middle East.
- A known name in a trust-based market - having exported municipal castings for decades, the company is already a familiar supplier in quality-sensitive markets across Europe and the Middle East, where buyers are slow to switch vendors on parts that carry vehicle loads or seal utility networks.
- Priced off the metal exchange, hedged both ways - selling prices are reset monthly against published LME (London Metal Exchange) benchmarks, which means input scrap costs and finished-product prices move together, providing a natural hedge; foreign-exchange exposure on the 90%-plus export book is managed with forward contracts and currency options.
- Now reaching the contractor, not just the distributor - the historical model relied on distributor partners in export markets; the company is now setting up wholly owned subsidiaries in Saudi Arabia, the UAE and the UK to sell directly to contractors, shorten delivery times and keep the margin that the middleman used to take.
The Durgapur plant: a single automated campus with room to grow
One 20-acre site in West Bengal houses every step from scrap recycling to finished casting, running at a quarter of its installed capacity - so volume can rise without building another factory.
- 72,000 tonnes of annual capacity, lightly used - the plant can produce 72,000 metric tonnes a year but ran at roughly 25% utilisation in FY25, leaving substantial headroom to absorb new orders before another expansion is needed.
- Automated for consistency, not just speed - robotic arms handle painting and grinding, automatic pouring systems control the metal flow, and high-pressure moulding lines shape the sand, which together produce repeatable quality with low labour cost per unit.
- Scrap goes in, castings come out - the plant runs on recycled iron scrap, much of it sourced locally in West Bengal, and spent moulding sand is reclaimed through an in-house recycling system, so the site operates on circular-economy principles.
- Built in waves, not all at once - a greenfield foundry was established in Burdwan in 2013, a vertical moulding line added in 2015, capacity tripled to 72,000 tonnes with robotics in 2021, and another moulding line completed in 2023; each step was funded before the next began.
- Preparing for a carbon-regulated world - the company is investing in solar power, afforestation on the 20-acre campus, and greater use of recycled content to get ahead of the EU’s Carbon Border Adjustment Mechanism, which will tax imports based on their carbon footprint.
Group structure and partners
A single Indian parent company is now planting its own flag in three overseas markets, each through a wholly owned subsidiary that will stock, sell and eventually manufacture closer to the customer.
- Saudi Arabia: from sales office to factory - SIF Saudi Arabia Company Limited was incorporated in December 2024 and, by August 2025, had signed a 10-year land lease with the Saudi industrial authority for a 9,141-square-metre plot in Dammam 3rd Industrial City, where it must complete at least half the construction of a cast-iron foundry within 24 months.
- UAE: a trading and manufacturing hub - a wholly owned subsidiary in the Hamriyah Free Zone, Sharjah, was incorporated in June 2025 to trade and eventually manufacture ductile and cast-iron infrastructure castings, creating a Middle Eastern hub for the company.
- United Kingdom: a direct line to the British construction market - Grounded Building Products Ltd was approved by the board in June 2025 to be incorporated as a wholly owned subsidiary to undertake activities relating to building and construction products and supply of materials in the UK.
- All subsidiaries are 100% owned for cash - each overseas entity is funded through a cash subscription to share capital at face value, with no other interest held by the promoter group, keeping the structure clean and wholly controlled.
- The Indian parent remains the manufacturing anchor - the Durgapur plant supplies the group, while UCO Bank and State Bank of India provide the working-capital lines, and the company carries a credit rating of IVR BBB- (stable) on its bank facilities.
