Years of Leadership in the Boiler Industry

Welcome

Allied Alloy Products

Allied Alloy is a 100% family-owned company specializing in boiler design & manufacture in Yamuna Nagar, India. The company was founded by Mr. D.P. Bantra in 1970, following his successful tenure with Indian Sugar & General Engineering Corporation (ISGEC). His vision was clear: develop high quality boiler and pressure products using indigenous techniques and locally sourced resources. This enabled the development of boiler and pressure parts at small scale at a time when it was only done at large-scale facilities. The breakthrough allowed Allied Alloy to deliver highly custom boiler solutions that are durable and efficient.

Today, Allied Alloy stands as one of the leading industrial boilers suppliers in India. We are trusted for delivering products that meet the highest standards of performance, safety and efficiency. We proudly serve a variety of industries including food processing, agriculture, hospitals, hotels, oil & gas, petrochemical, and more.
