Addressing the seismic challenges faced by Nepal as an earthquake-prone zone, Jagdamba Steel leverages over two decades of experience in manufacturing high-quality Steel Rebars to introduce Jagdamba E Steel Rebar. This groundbreaking product, a Fe 500 Grade Earthquake Resistant Steel Rebar, stands as the first and only one of its kind in Nepal. Jagdamba E Rebars conform to the Fe-500 Grade quality standards set by the Nepal Bureau of Standards and Metrology (NS:191 Certification), Bureau of Indian Standards (BIS, ISI Certification IS:1786:2008), and New Zealand Standards.
Designed to cater specifically to earthquake-resistant constructions, Jagdamba E is highly recommended for applications in residential homes, commercial buildings, and infrastructure projects. Given Nepal's heightened vulnerability to seismic risks, the application of Jagdamba E Steel Rebar becomes instrumental in minimizing potential damage to RCC structures during earthquakes, thereby contributing to the preservation of lives through its resilient features.
Jagdamba E distinguishes itself through a set of exceptional features that epitomize cutting-edge steel manufacturing. Crafted from prime billets within a state-of-the-art, fully automated modern plant, Jagdamba E Rebars undergo Thermo Mechanically Treatment (TMT). This process not only enhances their strength but also imparts superior ductility, rendering them resilient to seismic conditions. The product benefits from the innovative prowess of Jagdamba Steels Ltd, a trailblazer and the premier steel producer in Nepal.
The assurance of superior quality in Jagdamba E Rebar is rooted in meticulous control throughout the manufacturing process, exemplified by:
Rigorous chemical and physical tests are applied to the raw materials, ensuring their adherence to high-quality standards. This stringent control guarantees consistency and quality in every single Rebar produced.
Jagdamba E Rebars are meticulously manufactured in the sole fully automated plant in Nepal. Automation ensures uniform physical qualities, such as consistent rib patterns and lengths. The Rebars undergo comprehensive chemical and physical testing in state-of-the-art computerized labs, ensuring swift results, immediate intervention, and reliability in quality assurance.
The maintenance of precise physical and chemical parameters is paramount for ensuring the superior quality of Rebars. Automated systems are employed throughout production, thermo-mechanical treatment, and testing processes. These parameters strictly adhere to the standards outlined by Indian BIS (IS: 1786:2008 Certification Standards) and NS 191 (Nepal Bureau of Standards and Metrology Certification Standards), encompassing both minimum and maximum thresholds. This meticulous control ensures the consistency and excellence of Jagdamba E Rebars.
Jagdamba E sets itself apart by exhibiting superior fatigue resistance compared to standard Rebars, thereby significantly influencing the fatigue strength of reinforced concrete. Tailored for applications subject to cyclic loads like heating and cooling cycles, repetitive inward loads, and multi loads, Jagdamba E emerges as the unequivocal choice for enduring performance.
Crafted from prime billets sourced from leading companies such as Jindal Steel, SAIL India, and TATA Steel, Jagdamba E Rebars epitomize a commitment to superior raw materials. This meticulous selection ensures that the Rebars attain the zenith of high-grade quality, contributing to their exceptional performance.
In a league of its own compared to standard Steel Rebars in Nepal, Jagdamba E distinguishes itself with superior ductility. This heightened ductility translates into increased elongation under stress conditions, a critical factor in seismic events like earthquakes. Jagdamba E outshines with a remarkable 20% more elongation compared to conventional Steel Rebars. Its strength and ductility surpass the minimum levels mandated by NS, IS, and other international standards.
Jagdamba E Rebars feature an outstanding 60-degree uniform rib pattern with enhanced depth and closer rib spacing, meticulously crafted through computer-controlled CNC-grade machines. This superior rib pattern ensures optimal bonding of Rebars with concrete reinforcement, fortifying the structural integrity of constructions.
Jagdamba E Rebar stands out for its exceptional bendability, attributed to its superior ductility, elongation, tough outer surface, and soft inner core. The Rebar exhibits remarkab-le flexibility without any associated risk of cracks or breakage.
Distinguished by a low carbon content, Jagdamba E Rebars boast superior weldability when the need arises. Notably, manual arc welding requires no pre-warming or post-welding procedures. The Rebar facilitates both butt welding and lap welding with ease.
Ensuring unwavering quality, the raw material billets and manufactured Rebars undergo rigorous chemical and physical testing in state-of-the-art, fully computerized labs. This meticulous process guarantees instant results, expedites intervention in the quality control process, and elevates overall reliability.
