WHAT ARE PEB’S?
PEBs are factory-fabricated steel structures designed and customized off-site and assembled on-site. PEBs are ideal for warehouses, factories, data centers, logistics parks, airports, and now even high-rise commercial spaces.
They offer various advantages over traditional structures like:-
Reduce construction time by 40–50%
Lower costs by optimizing material use and labor needs
Improve sustainability by minimizing on-site waste
Enable scalability and repeatability for industrial applications
BUSINESS MODEL
Interarch operates as a pure-play PEB solutions provider, differentiated by:
In-House Execution: The company manages all aspects of project execution in-house — from design, engineering, and fabrication to logistics and on-site erection — eliminating third-party dependencies and ensuring consistent quality and speed.
Turnkey Contracts: Its turnkey delivery model is built around fixed-price, lump-sum contracts rather than per kilogram or per square foot pricing, demanding upfront precision in engineering and cost control.
Execution Speed: Interarch is known for its execution speed, delivering even large-scale and technically intensive projects, including ₹300+ crore orders, within a 9 to 12-month timeframe.
Client-Centric Approach: The company’s internal teams — across sales, engineering, production, and project management — are tightly aligned with client timelines and specifications, reinforcing its reputation for reliability and repeat business.
MANUFACTURING FACILITY
They currently have five manufacturing facilities two in Sriperumbudur, Tamil Nadu; one in Pantnagar , Uttarakhand; one in Kichha , Uttarakhand; one in Athivaram , Andhra Pradesh with a total installed capacity of 161,000 Metric Tons Per Annum (MTPA). Currently they are working at 80% to 85% capacity utilisation at these plants.
The advantage of establishing a facility in the southern, western, or northern regions of India is that, within the PEB (Pre Engineered Buildings) sector, it is highly beneficial to be located within 500-1000 km of customers. This proximity allows for quicker and more efficient delivery, ensuring better service to meet the needs of the PEB segment.
CAPEX PLANS
Phase I capacity expansion at Athivaram was completed in 2024. 20,000 MTPA capacity was added. The project has a revenue potential of ₹150 cr.
The Phase II capacity expansion planned at Athivaram , Andhra Pradesh is underway and will be ready sometime in Q1FY26. It would add around 40,000 MTPA capacity. They will invest ₹58 cr funded through IPO proceeds
Future expansion

Further they will spend ₹80 Cr capex in FY26.
