Registered Vendor — BHEL · NLC India
Based in Viralimalai, Rupak Engineering delivers comprehensive, end-to-end industrial steel structures and equipment tailored for the power and Public Sector Undertaking (PSU) sectors. Our state-of-the-art workshop seamlessly integrates drawing-driven fabrication, certified welding, and turnkey on-site execution, all under one roof.
Established in 1999, Rupak Engineering is a steel fabrication contractor based in Viralimalai, specialising in the machining and fabrication of boiler components and general industrial fabrication. We work from approved drawings through to dispatch and site handover, covering heavy and structural steel, alloy and stainless steel fabrication, mechanical works and on-site execution.
Our work is built around the documentation that PSU and EPC clients expect: drawing-controlled fabrication, qualified welders, dimensional inspection, and material traceability. That discipline earned us approval as a registered sub-contractor to BHEL Trichy and vendor registration with NLC India.
