High-Rise Commercial Curtain Wall & Unitized Facade Steel Systems
High-precision engineering steel packages supplied to facade fabricators and glazers for high-rise unitized curtain walls, double-skin facades, and architectural exterior louvers.
Engineering & Strategic Scope
Modern high-rise commercial architecture relies heavily on high-performance unitized glass curtain wall systems. Sarvottam Steel manufactures and supplies structural steel outriggers, wind brackets, and precision stainless steel anchors that secure thousands of square meters of glass to building concrete superstructures.
Architectural Expression & Spatial Dynamics
The facade steelwork enables uninterrupted all-glass building envelopes that maximize indoor daylight and panoramic city views. Slender internal steel stiffeners inside hollow aluminum mullions provide the necessary inertia to achieve 4-meter floor-to-floor glass panels without visible bulk.
Structural Rigor & Critical Environmental Criteria
Three-Axis Adjustment: Concrete casting tolerances (+/- 25mm) require steel brackets to incorporate slotted holes and serrated washers for precise 3D leveling.
High Wind Suction at Building Corners: Corner glass zones experience localized negative wind vortex suction pressures reaching 2.5 kPa during coastal monsoons.
Galvanic Corrosion Prevention: Direct contact between steel anchors and aluminum mullions required non-conductive EPDM isolation pads and stainless steel fasteners.
