What Steel Products does

Steel Products Limited is a Kolkata-based engineering and infrastructure services company specializing in the installation of OPGW (Optical Power Ground Wire) and ADSS (All Dielectric Self-Supporting) fiber optic cables on high-voltage power transmission lines ranging from 66KV to 765KV. Incorporated in 1917 as one of the oldest public limited companies listed on the Calcutta Stock Exchange, the firm originally operated a small-scale unit manufacturing Galvanized Hamilton Tubular Poles before pivoting in the early 2000s to become India's first adapter of OPGW live-line and off-line installation technology. It serves power transmission utilities, oil and gas enterprises, and telecommunications infrastructure operators across South Asia, with operations in India, Bangladesh, Bhutan, Nepal, and Myanmar.

The company offers an integrated suite of services anchored on proprietary live-line installation capability using cradle block technology that allows fiber optic deployment on energized transmission lines without power shutdown. Its offerings include OPGW and ADSS installation and commissioning across multiple voltage classes, recurring annual maintenance contracts for OPGW/ADSS/UGFO networks (currently covering 24,335 km of installed infrastructure across Indian utilities), end-to-end EPC contracts covering tower design, fabrication, galvanizing, civil works, erection, and stringing of EHV transmission lines, supply of transmission and telecommunication towers, and dedicated OPGW training programs for utility personnel. Technical credentials include installations at extreme altitudes (up to 2,900 meters in Jammu and Kashmir), sea crossings (1,800 meters at Ganga Sagar, West Bengal), and long spans (1,410 meters in Bhutan).

Steel Products Limited operates a B2B enterprise sales model targeting government-owned power utilities and large state-owned enterprises, with all contracts secured through competitive tendering and direct negotiation based on technical qualifications and past performance. Revenue is generated through project-based professional services, recurring managed services maintenance agreements, and hardware sales of transmission line towers and structures. The customer base is anchored by Power Grid Corporation of India Limited (PGCIL), supplemented by state transmission utilities, international power entities, and adjacent-sector clients including Bharat Petroleum Corporation Limited and BSNL. Pricing is quote-based and not publicly disclosed, reflecting the project-contract nature of the business.
