Industry Outlook
- India’s structural steel industry is undergoing a robust expansion, driven by the country’s accelerating infrastructure development and industrial modernisation. Structural steel forms the backbone of large-scale construction projects, playing a pivotal role in bridges, highways, railways, high-rise buildings, oil and gas facilities, and manufacturing plants.
- The sector has witnessed a significant rebound post-pandemic, with finished steel production reaching 139.4 million tonnes in FY 2024—a 12.7% increase over the previous year. This growth has been largely propelled by private sector contributions, accounting for 85% of total output. Non-flat steel products, primarily used in construction, comprised 55% of production, while flat products, utilised in automotive and appliance manufacturing, made up the remaining 45%.
- Government initiatives such as the National Infrastructure Pipeline and “Make in India” have catalysed demand, alongside increased capital expenditure in mining, manufacturing, and construction. The Index of Industrial Production (IIP) reflects this momentum, with the manufacturing index growing by 5.5% in FY 2024 and the construction sector registering a 9.9% year-on-year increase.
- Technological advancements, including energy-efficient processes and the use of recycled scrap steel, are enhancing production capabilities and sustainability. Moreover, the global appetite for steel has encouraged Indian producers to scale output, positioning India as the second-largest crude steel producer globally.
Karbonsteel Engineering IPO Objectives
The company proposes to utilise the net proceeds from the IPO for the following objectives:
- Expand manufacturing infrastructure by undertaking capital expenditure towards the development of two new fabrication sheds at its existing Umbergaon facility in Gujarat. This expansion includes civil construction, procurement and installation of advanced machinery, and layout optimisation to support increased production capacity. One shed will be dedicated to railway infrastructure projects such as Foot Over Bridges (FOBs), Road Over Bridges (ROBs), and steel girders, while the other will enhance general fabrication operations. Upon completion, the facility’s installed capacity is expected to increase from 30,000 MT to 42,000 MT per annum.
- Strengthen financial stability through the repayment of a portion of existing borrowings availed from HDFC Bank, ICICI Bank, and IDFC Bank. This will reduce interest obligations, improve the company’s debt-to-equity ratio, and enhance its credit profile for future financing needs.
- Support working capital requirements to ensure uninterrupted operations, timely procurement of raw materials, and efficient execution of ongoing and future projects. This will enable the company to maintain optimal inventory levels, meet client delivery schedules, and manage receivables more effectively.
- Fund general corporate purposes, including administrative overheads, brand development, and strategic initiatives aimed at reinforcing the company’s market presence, operational resilience, and long-term sustainability.
