Forged Steel Rolls & Cast Steel Rolls | Cold & Hot Rolling Mills
We make every type of roll that is used in the steel mill industry, and apply our patented coating and heat treatment technology to our rolls to ensure smooth operation for our clients.
Our extensive experience in engineering and manufacturing various roll materials and surface treatments has positioned us as a trusted long-term supplier for global steel mills and their key equipment providers. To better serve our clients, we established a joint R&D team with our steel mill partners to develop innovative technologies that address their specific challenges. This collaborative approach has solidified our reputation as a reliable supplier and has enabled us to maintain a competitive edge in the industry.
Cold Rolling Mill and Finishing Line Rolls
We make all types of cold rolling mill rolls and entire finishing line rolls: pickling / tandem cold mills, annealing pickling lines, continuous pickling lines, continuous galvanizing lines, electro-galvanizing lines, continuous annealing lines, and color coating lines.
Surface quality and finish are crucial for cold strip mills or cold rolling mills, which process sheet metal to reduce thickness without using heat, resulting in thin metal strips often used in automotive parts. These strips must be free of roll marks, making the production of rolls for this process demand years of precision grinding and coating expertise.
Types of rolls we make for each section include:
- Tensioning section: bridle roll, deflector roll, pinch roll, looper roll, snubber roll, anti climping roll and work roll
- Transfer section: steering roll, table roll, flattener roll, idle roll, ceramic rolls, dry rolls and support roll
- Furnace: hearth roll and seal roll
- Zinc pot: sink roll, stabilizing roll and conductor roll
- Other finishing line rolls: wet roll, wringer roll and V rolls
Cold rolling mill work rolls are made with high chrome forged steel with hardness range of Hs92 and Hs96. Our heat treatment guarantees the hardened depth of 15 mm to 20mm on the roll side.
We provide many types of coating for the rolling mill environment, such as chrome plating, thermal spray, brush, rubber, poly and nylon. We also provide chrome plating and tungsten carbide chrome plating for high-hardness bridle rolls used in CGL and CAL lines. Our products are utilized by leading global steel mills, including POSCO, Hyundai Steel, JSW, JP Steel, and Nippon Steel.
Unsure which coating material or method to go with? We will suggest the best surface coating method based on our manufacturing knowledge and experience.
Sink Roll and Hearth Roll for Cold Rolling Mill Galvanizing and Alumina Zinc Line
Our hearth rolls and sink rolls come with chrome plating and thermal spray coatings to make them ready for use in furnace applications for galvanizing and alumina zinc lines. They are currently in operation at JSW steel mills and China steel mills. We use Praxair, Tocaro or equivalent brands for the thermal spray coating, and our centrifugal casting furnace roll has a maximum diameter of 1,500mm / 59 inches.
Hot Strip Mill Rolls or Hot Rolling Mill Rolls
We offer a complete range of rolls for the entire hot strip mill process, including the reheat furnace, roughing, finishing mill, cooling, and down coiler sections. Our work rolls are made with cast iron, produced by Hyundai Steel’s iron foundry, and we provide mill certificates along with country-of-origin documentation for all shipments to our clients.
Our selection of table rolls for hot rolling mills includes descaling rolls, entry and exit rolls, runout rolls, work rolls, and unit rolls. These rolls feature patented noise-dampening technology that reduces noise, provides a cushioning effect, extends the roll’s lifespan, and minimizes heat and weight deformation.
For the reheating furnace, we make descaler table rolls from CrMoLy forged material. For the roughing section, we provide entry and exit table rolls, also made from CrMoLy forged material. In the finishing mill, our table rolls are made from forged steel. In the cooling zone, we offer runout table rolls with a surface treatment of Wire Spray Metco15c. Lastly, for the down coiler section, we supply unit rolls made from SUJ2 material combined with a special thermal spray.
Plate Mill Levelling Machine Rolls
While we supply rolls for entire plate mill lines, our leveling rolls are especially sought after by steel mills and suppliers of cold and hot leveling machines. Our extensive experience in manufacturing and fabricating with materials such as high-chrome alloy forged steel, austenitic stainless steel, and molybdenum alloy steel is crucial for producing high-quality leveling rolls. These rolls are currently in operation at leading companies like Hyundai Steel, Nippon Steel, JFE, and KOBE Steel.
For the reheating furnace in the plate mill, we make descaler table rolls from CrMoLy forged material. For the roughing section, we provide entry and exit table rolls, also made from CrMoLy forged material. In the finishing stand mill, our feed rolls are surface-treated with a hard-facing weld, made from CrNi. For hot leveling, we offer leveling rolls made from either SUS420J2 or 86CrMov material. In cold leveling, our leveling rolls are made from 3% Cr forged material. Finally, in the terminal section, we supply table rollers constructed from S45C or SCM440-QT.
Guide Rolls for Continuous Casting Line
We apply our patented hardfacing technology on our guide rolls for continuous casting lines in order to extend their service life. Our guide rolls are currently in operation in USA, Japan, Korea, France, and Germany, among other countries.

Press Rolls for Electric Battery Manufacturing Line
Our journey in press roll technology began in 2006, when we established ourselves as a roll and roll assembly repair shop for global steel mills. Today, we are a leading global supplier of rolls to steel mills, EV secondary battery material manufacturers, and equipment manufacturers. Our expertise in roll surface grinding technology, coating materials, and heat treatment techniques is fundamental to our press roll technology.
After earning the trust of our clients through our roll sales, we expanded our services to include maintenance for leveller cassettes, which involves regrinding leveller rolls and backup rolls. Over the past decade, we have continued to support leveller assembled rolls and skin pass mill assembled rolls. The knowledge we’ve gained in roll grinding and surface coating has become the cornerstone of our high-quality press rolls for electric battery electrode manufacturing.
EV Battery Electrode Manufacturing Press Rolls
The quality of lithium-ion and iron battery electrodes is closely linked to the density of the electrode mixture. To achieve a uniform density, the mixture is processed through a set of two work rolls, similar to the mechanisms used in steel rolling mills. The pressure from these press rolls ensures an even improvement in electrode density. By managing the coating thickness, distribution, and adhesion on conductive substrates (such as aluminum and copper foil) for the slurry, our press rolls significantly enhance both the electrode quality and, ultimately, the overall performance of the batteries.
Roll Grinding and Surface Coating Technology
Since 2021, we have been supplying top EV battery material manufacturers with 3% and 5% hard-chrome plated press rolls. Our rapid growth in press roll sales is driven by our exceptional expertise in roll grinding and coating technology. Superfinishing the roll surface presents a common challenge for roll manufacturers in the EV battery sector, along with developing coating methods that enhance roll longevity in the harsh, acidic environment of battery materials.
Our goal is to become the leading press roll manufacturer for the EV industry worldwide. Please consult with us your electrode calendaring process.
