With an annual capacity of approximately 900,000 tons, IRM produces a wide variety of grades of which over 80% are destined for sophisticated Cold Heading, High carbon and Weld applications. Supported by both EAF(Electric Arc Furnace) and BOF(Basic Oxygen Furnace) sourced billets, IRM is well positioned to satisfy the evolving needs of our customers.
Reducing – sizing mills on both strands provide exceptional size control, tensile uniformity and required descalability ensuring optimal quality.
Our current grade and size matrix is illustrated in the guidelines below, however IRM remains committed to developing new products in conjunction with customer needs.
