Interarch Building Solutions has approved a joint venture with ER Steel Inc., Canada, to jointly explore and develop the Open Web Steel Joists (OWSJ) business for the North American market. The Board of Directors approved the agreement on August 6, 2026, aiming to capture 2 to 5% of the market share in the next three years. This strategic move opens a new revenue stream by combining Interarch’s engineering and manufacturing strengths with ER Steel’s established presence in the USA and Canadian markets.

The disclosure was made pursuant to Regulation 30(6) read with Schedule III of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, and SEBI Circular No. HO/49/14/14(7)2025-CFD-POD2/I/3762/2026 dated January 30, 2026. The company confirmed that the transaction does not fall within related party transactions and that no promoter or group company has an interest in the entity being acquired.

Joint Venture Structure

The proposed collaboration establishes a structured framework for evaluating the design, engineering, manufacturing, and supply of OWSJ products through a scalable platform in India. Interarch will lead engineering, detailing, manufacturing, and quality compliance activities from India. ER Steel will primarily support market development, customer relationships, and sales and marketing activities in Canada and the USA.

Funding and Commitments

The total initial investment planned is ₹80 crore. An amount equal to 25% of the Initial Cost shall be contributed at the Initial Closing via incorporation capital by Interarch and remittance of initial contribution by shareholders. The balance 75%, amounting to ₹60 crore, will be contributed in three equal tranches of ₹20 crore each. Interarch and ER Steel will contribute committed capital in the agreed shareholding ratio of 76:24.

ER Steel must enter into an Offtake Agreement with the Joint Venture Company (JVCo) to purchase a minimum quantity of OWSJ products for distribution and sale in Canada and the USA. This serves as a major commercial assurance for the JV. Interarch will incorporate the JVCo in India, and the JVCo will execute a Deed of Adherence to be bound by the JV terms once incorporated.

Strategic Rationale

The partnership leverages ER Steel’s presence in the target markets to open new opportunities for Interarch. Management stated that Interarch’s strength in engineering and manufacturing combined with ER Steel’s knowledge and presence creates a strong basis for success. Depending on the growth of the business, the company retains the option to expand further beyond the initial investment.
