M&B Engineering is fundamentally a factory-built alternative to traditional concrete construction - it designs, makes and installs steel buildings and roofs that go up faster, use less material and need roughly a quarter of the labour. The business began in 1951 as a conventional construction firm and later reinvented itself around two proprietary systems: Phenix for pre-engineered buildings and Proflex for self-supported roofing, each sold under its own brand. The recurring approach is a design-led-manufacturing model - the company engineers the structure in 3D first, fabricates it in a controlled plant, then erects it on site, which is how it has delivered over 10,000 projects across 23 countries. # Business segments Two engines built on the same design-led-manufacturing logic - a pre-engineered buildings business that is the group's anchor, and a self-supported roofing business that leads its category in India, each with its own brand, factory network and customer base. ## 1. Phenix: where the group's scale and export reach sit **It makes entire steel-framed industrial buildings in a factory and ships them to site - 73,000 tonnes of them in the last year alone, with a third of the order book now coming from North America.** - **A building system, not just steel** - Phenix supplies pre-engineered buildings (PEBs), which are steel structures fabricated indoors and bolted together on site, along with heavy structural components like T-beams and box beams; the division has completed more than 1,650 projects and installed over 710,000 tonnes since it started 18 years ago. - **The American certification that rivals lack** - its Sanand plant in Gujarat is the only PEB facility in India certified by the American Institute of Steel Construction (AISC), a requirement most US general contractors insist on, and it also holds Canadian Welding Bureau (CWB) approval, which is mandatory for supplying into Canada. - **Two plants, with a third on the drawing board** - the Sanand facility (72,000 tonnes annual capacity, expanding by roughly 20,000 tonnes by mid-2027) and the newer Cheyyar plant in Tamil Nadu (31,800 tonnes) serve domestic and export demand, while a third plant is planned near Lucknow to cover northern and eastern India. - **A 98-person engineering team does the design work upfront** - the division runs its own in-house design offices in Hyderabad, Chennai and Ahmedabad, using software like STAAD PRO, TEKLA and MBS to create 3D models before a single beam is cut, which is what the company means by "design-led manufacturing". ## 2. Proflex: India's largest self-supported roofing business **It makes curved steel roofs that hold themselves up without trusses or columns, manufactured on the back of a truck at the customer's doorstep.** - **The arch does the structural work** - Proflex roofs achieve stability through their curved shape, eliminating the need for trusses, purlins or intermediate supports; they span from nine to about 34 metres, are leak-proof and remove the problem of birds nesting in the structure. - **The factory moves to the site** - a fleet of 15 mobile manufacturing units, with a combined capacity of 1.9 million square metres a year, allows on-site or near-site production, cutting out the cost of transporting finished roof sections across long distances. - **Warehouses and railways are the biggest customers** - in the last year, 42% of Proflex revenue came from warehousing and 14% from railways, where the division has completed over 300 projects in the railway sector with cumulative installation of 0.6 million square metres. - **A 24-year head start in a niche** - the division has delivered more than 8,600 projects and installed over 20 million square metres since it began, making it the largest player in India's self-supported roofing segment by revenue. # Group structure and partners **Two divisions, two brands, one listed entity - with a US subsidiary that serves as the North American sales outpost.** - The company operates through its Phenix and Proflex divisions, with the Phenix brand carrying the tagline "Creation Simplified" and Proflex using "Innovate. Lead. ROOFING SOLUTIONS". - A wholly owned subsidiary, Phenix Construction Technologies Inc., was set up in the US in 2017 and now fields a five-person sales team on the ground in the Eastern United States, selling directly to general contractors. - The two joint managing directors split the leadership: Malav Patel runs sales, marketing and administration, while Chirag Patel oversees operations and techno-commercial strategy; each division has its own CEO.
