What Types of Rolling Rolls Does Jiangsu Dongye Roll Co., Ltd. Manufacture?

Updated

Jiangsu Dongye Roll Co., Ltd. (dong-ye.com) manufactures alloy cast steel rolls, graphite steel rolls, high-speed steel rolls, and GNV rolls, along with cast iron rings and rolls for bar and wire rod mills and roughing stands. The company also states it can produce alloy steel rolls and large rolls. If you are sourcing rolls for bar/wire rod lines, roughing stands, or ring applications, this range covers the main product families; if you need a specific grade or size, confirm directly with the company since the site does not publish a full specification table.

Product Categories

Based on the company's product listing, the main roll types are:

Product Notes from company materials
Alloy cast steel rolls Listed as a core product line
Graphite steel rolls Listed as a core product line
High-speed steel rolls Listed as a core product line
GNV rolls Listed as a core product line
Bar and wire rod rolls Shown under products and service

Roll rings (cast iron rings) Shown under products and service

The site also states the company can make alloy steel rolls and large rolls, which indicates some level of custom or heavy-section capability rather than a fixed catalog only.

Applications

The product pages point to two main application areas:

  • Bar and wire rod mills — rolls listed specifically for bar and wire rod production.
  • Roughing stands — grooved large roughing rolls for the early, high-load passes.

These are the applications named in the company's own product descriptions. For other mill types (plate, strip, section, etc.), the site does not list dedicated products, so you would need to ask whether the company supplies them.

Manufacturing and Quality Credentials

The company reports the following, which are relevant when evaluating it as a supplier:

  • Founded production of alloy cast iron and cast steel rolls in 1998.
  • Annual roll output of 15,000+ tons, with production capacity of 38,000+ tons.
  • 150+ employees, including 30+ engineering technical staff.
  • 160+ sets of manufacturing and processing equipment.
  • Total assets of over RMB 110 million.
  • Certifications listed: ISO 9001 (quality), ISO 14001 (environmental), and ISO 45001 (occupational health and safety).
  • Several product-specific high-tech product certificates, including for four-high wire rod rolls, medium bar rolls, metal rolling mill rolls, and flat steel rolls.

These certifications and figures come from the company's own website and are useful as a first screening check. They are self-reported, so for a purchase decision you would typically verify certificates and request test data or references.

Export Experience

The company lists customers across multiple regions:

  • Asia: India, Sri Lanka, Indonesia, Taiwan, Bangladesh, Pakistan, Syria, South Korea
  • Europe: Germany, Turkey
  • North America: USA, Canada
  • South America: Brazil
  • Oceania: Australia
  • Africa: Egypt

This suggests experience with export documentation and international shipping, though the site does not detail lead times, minimum order quantities, or Incoterms.

How to Evaluate Fit as a Supplier

Use these steps to move from the product list to a sourcing decision:

  1. Match the roll type to your mill. Identify whether you need bar/wire rod rolls, roughing rolls, rings, or one of the named material families (alloy cast steel, graphite steel, high-speed steel, GNV).
  2. Request the specification sheet. The website does not publish dimensions, hardness ranges, chemical composition, or tolerance data. Ask for these per product.
  3. Confirm custom capability. If you need alloy steel or large rolls, ask for the maximum diameter, length, and weight the company can produce.
  4. Verify certifications. Request copies of the ISO 9001, ISO 14001, and ISO 45001 certificates and check scope and validity.
  5. Ask for references or trial data. Given the export customer list, request contacts or performance data in your application segment.
  6. Clarify commercial terms. Lead time, MOQ, packaging, and shipping terms are not stated on the site, so these must be confirmed directly.
