Mumbai Metro Elevated Viaduct & Pier Steel Fabrication
High-strength metallurgical steel supply for elevated viaduct piers and critical rail overbridge crossings across Mumbai's high-density arterial corridors, engineered for high saline groundwater and heavy dynamic transit loads.
Engineering & Strategic Scope
Expanding Mumbai's suburban mass rapid transit network requires constructing hundreds of kilometers of elevated viaducts over narrow city thoroughfares and railway crossings. Sarvottam Steel supplied high-ductility Fe 550D reinforcement rebars and heavy E350 steel plates for viaduct substructures and launching gantries.
Architectural Expression & Spatial Dynamics
The elevated viaducts employ single-pier hammerhead columns that minimize right-of-way disruption at ground level. The clean structural lines of the precast segment viaduct provide an uncluttered aesthetic while carrying dual high-frequency rail tracks overhead.
Structural Rigor & Critical Environmental Criteria
Chloride-Rich Saline Groundwater: High tidal water tables along coastal creeks required TMT steel with tightly controlled chemical purity to inhibit pitting corrosion.
Heavy Prestressing Reactions: Pier cap zones experience intense anchorage forces from prestressed concrete tendons, demanding ultra-high yield strength Fe 550D confinement rebars.
Congested Underground Utilities: Foundation piles had to be positioned around live water mains and high-voltage transmission lines, requiring custom rebar detailing.
