Our rolling mills are available in both 2Hi and 4Hi roll configurations, and mills may be either work roll driven, back-up roll driven, or a combination of both. Custom Rolling Mill machines are FENN’s specialty, and we invite you to contact us with inquiries regarding any size and configuration!

  • 4HI mills with work rolls are offered as small as .500″ (12.7 mm) in diameter.
  • 2HI mills are offered with rolls up to 16″ (400 mm) in diameter.

Rolling Mills
& Offerings

Designed and built to your production requirements

FENN rolling mills are engineered to meet the critical requirements of metallurgical research and applications up to 3.3 million lbs. (1500 MT) separating force. FENN designs and builds rolling mills available with a complete offering of material handling options, processing, gauging and labor-saving accessories. FENN offers customizable rolling mills for the processing of ferrous, non-ferrous, alloy, exotic and engineered metals for production and laboratory applications.



We offer hot and cold milling machinery as well as combination mills that can accommodate both hot and cold rolling applications. Hot rolling is a process in which the metal is heated to above the recrystallization temperature, allowing the material to deform on a microscopic level and take its new shape. On the contrary, cold rolling is when the process is conducted at room temperature and does not require heating the metal. Learn more about the difference between hot and cold rolling mills.

Typical Materials Type of Mills Applications
Steel Superconducting Research Bonding Rod Material Research
Copper Exotic Metals Mint Strip Aerospace
Lead Precious Metals Powder Sheet Consumer
Aluminum Ferrous Hot Rolling Plate Automotive
Platinum Non-Ferrous Cold Rolling Renewable Energy/Military

Unusual application? No Problem!

We have experience with a variety of applications. A few examples of how our customers have used FENN rolling mills:

  • Breakdown rolling either straight lengths or coil to coil
  • Finish rolling for tight tolerance thing gauge stock
  • Powder metallurgy rolling
  • Bonding dissimilar metals together
  • Laboratory mills used for research and development (R&D)
  • Camber correction of BI-metal strip after electron-beam welding
  • Grooved rolls for rod rolling of square or circular sections
  • Embossed rolls for pattern rolling

Mill Types


FENN offers a full range of mill types for the production of precision strip in straight lengths or coil to coil rolling.

1 – Two-High

2 – Three-High

3 – Four-High

4 – Combination

5 – Tandem

6 – Horizontal

7 – Laboratory

8 – Mill with Winders

  1. Two-High: Generally, a 2-HI mill is used for hot or cold breakdown and finishing of bar, sheet or strip. A wide range of sizes with separating force capacities from 10,000 lbs. (4.53 MT) to over 3,000,000 lbs. (1360 MT) are available.
  2. Three-High: A 3-HI mill is an economic milling solution for the breakdown of rod and ingot.
  3. Four-High: A 4-HI mill may be used for finish rolling of thin gauge stock. 6-HI roll inserts are also available for narrow width ribbon and foil products.
  4. Combination: A combination rolling mill is a versatile “two-in-one” type of metal rolling mill that permits both 2-HI and 4-HI rolling operations.
  5. Tandem: Tandem rolling mills are used for multiple pass rolling, combining two or more mill stands. Tandem mills are often used with turks heads, edgers, dancers, inter-stand tensiometers, payoff and take-up equipment.
  6. Horizontal: This type of a rolling mill is designed for the field of powered metallurgy, plastics and battery industries.
  7. Laboratory: FENN designs custom, specialized mills engineered to meet the critical requirements of metallurgists and scientists in research and university fields, as well as pilot line development.
  8. Mill with Winders: A mill set up with winders on either side allows for the rolling of continuous coil for sheet or thin foil.

Accessories: A complete offering of material handling, processing, gauging and labor-saving accessories are available for all FENN Rolling Mills, including laboratory models.


Laboratory Mills


For research and development (R&D) applications, FENN manufactures laboratory rolling mills equipped with Statistical Process Controls (SPC) to track and record “real time” data. R&D projects may require the testing of multiple materials, laboratory mills are designed to accommodate a variety of materials for testing and manipulation. The precision strip mills we engineer are designed to meet the critical requirements of metallurgical research. With separating force capabilities from 30,000 lbs. (13.6 MT) to 1,175,000 lbs. (533 MT), our mills have received wide acceptance in laboratories, where precision, flexibility, and compactness are especially important. Our trusted engineers are prepared to work with research facilities, colleges, and universities to provide a customized mill suited to their unique requirements.
