International Rolling Mills maintains one of the most comprehensive inventories of precision rolling mills in North America — spanning new IRM-built machines, factory-refurbished equipment, and inspected used mills across the full spectrum of configurations, sizes, and specialty applications. Founded in 1978, IRM has refurbished and delivered thousands of rolling mills that remain in active service today at research institutions, national laboratories, aerospace manufacturers, defense contractors, and specialty metals producers worldwide.
Whether you need a compact laboratory mill for metallurgical R&D, a production-scale 4-High mill for thin gauge strip, a hot rolling system for refractory metals, or a custom-engineered solution for a process no standard machine can handle — IRM has the inventory, engineering depth, and manufacturing capability to deliver the right mill for your application.
IRM New-Build Rolling Mill Models
IRM designs and manufactures new rolling mills to customer specification. Standard in-stock models include the IRM 2040, 2050, 2560, and 4060 — available with a full range of optional features including heated rolls, load cells, data acquisition, digital height indicators, and automatic gauge control. Custom sizes and configurations available on request.
IRM stocks and builds rolling mills across every major configuration — from bench-top laboratory mills through large-scale production equipment. The tables below reflect IRM’s full capability range across material types, mill configurations, common sizes, supported brands, and available options.

Rolling mills from IRM serve a broad range of industries and applications — from fundamental materials research through production-scale specialty metals processing. Common applications include breakdown rolling, finish rolling, foil production, wire flattening, bonding and cladding, powder compaction, and laboratory process development.
Universities, national laboratories, and corporate R&D centers rely on IRM laboratory mills for metallurgical research, alloy development, and process optimization at bench and pilot scale. Optional data acquisition and load cell packages enable research-grade measurement and documentation.
Precision strip in titanium, Inconel, beryllium copper, and specialty structural alloys for aerospace components, connectors, shim stock, and defense applications. IRM mills are specified where traceability, repeatability, and tight thickness tolerances are non-negotiable.
Molybdenum, tungsten, tantalum, niobium, rhenium, and other refractory metals require mills built for the extreme forces and controlled conditions these materials demand. IRM hot mill configurations and high-force 2-Hi and 4-Hi mills are routinely specified for refractory metal processing.
Battery electrode foil, current collector strip, and solid-state electrolyte materials require ultra-thin gauge rolling with exceptional thickness uniformity. IRM 4-Hi mills and precision laboratory mills are used by next-generation energy storage developers and national laboratory programs.
Gold, silver, and platinum strip for coin blanks, jewelry, and bullion products requires highly controlled rolling with consistent thickness and surface finish. IRM mills are specified by precious metals processors and minting operations where material value demands process precision.
Thin strip and foil in high-purity metals — indium, copper, nickel, and specialty alloys — for sputtering targets, solder preforms, and semiconductor packaging. IRM precision mills provide the gauge control and surface quality these applications require.
Nitinol, titanium, cobalt-chrome, and stainless steel strip for implantable devices, surgical instruments, and diagnostic components. IRM mills support the tight dimensional tolerances and biocompatible material requirements of the medical device industry.
U.S. national laboratories, fusion energy programs, and advanced materials research institutions require mills capable of handling exotic alloys in controlled, low-volume environments. IRM laboratory and pilot-scale mills are specified for applications that standard production equipment cannot accommodate.
Founded in 1978, IRM has spent over four decades building, refurbishing, and servicing rolling mills for the most demanding applications in specialty metals processing. We design new equipment, rebuild existing machines to factory-new condition, and provide ongoing engineering support for mills already in service. Our Pawtucket, Rhode Island facility runs rolling trials on IRM equipment — so when we specify a mill for your application, it comes from actual operating experience, not a catalog.
When you work with IRM on a rolling mill, you’re working with engineers who have run these machines — not just salespeople who know the model numbers.
Rolling mill selection depends on your material, thickness range, width, required separating force, temperature requirements, and whether you need a lab-scale or production-scale solution. IRM’s engineering team works with buyers to identify the right mill — whether that’s a new IRM-built machine, a factory-refurbished Stanat or Fenn, or a custom-engineered solution for a process that doesn’t fit a standard catalog.
