|---|---|
| Description | नालीदार इस्पात छत (Nālīdār Ispāt Chhat), or corrugated steel roofing, represents a modern adaptation of traditional roofing techniques within the Indian subcontinent. Utilizing इस्पात (ispāt, steel), a ferrous alloy derived from iron ore sourced from regions like Odisha and Jharkhand, it offers a durable alternative to traditional materials. The steel undergoes processing, including galvanization, to enhance corrosion resistance, crucial in diverse Indian climates. Physical properties include a tensile strength of 400-500 MPa and a density of 7.85 g/cm³ [1]. While not directly linked to ancient structures, its adoption reflects evolving construction practices in the 20th and 21st centuries, particularly in industrial and agricultural contexts. Conservation efforts focus on managing rust ( जंग, jang) and maintaining the protective zinc coating. The material's thermal conductivity (50 W/mK) necessitates consideration in building design for thermal comfort. Future research could explore bio-based coatings to further enhance sustainability and reduce environmental impact, aligning with principles of *sthāpatya shāstra* (स्थापत्य शास्त्र, science of architecture). |
