Production Capabilities and Quality Certifications of Jiangsu Dongye Roll Co., Ltd.

Jiangsu Dongye Roll Co., Ltd. (dong-ye.com) is a roll manufacturer based in Dong'an, Huangli Town, Wujin District, Changzhou, Jiangsu. According to the company's website, it operates more than 160 sets of manufacturing and processing equipment, produces over 15,000 tons of rolls annually, and holds a stated production capacity of more than 38,000 tons. Its quality and management systems are certified to ISO 9001, ISO 14001, and ISO 45001. These figures and certificates indicate a mid-sized roll producer with an established quality management framework, though buyers should verify current capacity and certificate validity directly with the company.

Production Capabilities

The company describes itself as a joint-stock cooperative enterprise and a member unit of the metallurgical industry spare parts center. It began producing alloy cast iron and cast steel rolls in 1998.

The gap between current annual output (15,000+ tons) and stated capacity (38,000+ tons) suggests room to scale orders, but it does not by itself confirm delivery timelines or available spare capacity at any given time.

Product Range

The website lists the following roll types:

• Alloy cast steel rolls
• Graphite steel rolls
• High-speed steel rolls
• GNV rolls
• Bar and wire rod rolls
• Grooved roughing rolls
• Roll rings

The company states it can produce both alloy steel rolls and large rolls.

Quality Certifications and Honors

• ISO 9001 Quality Management System Certificate

• ISO 45001 Occupational Health and Safety Management System Certificate
• Listed enterprise on the Jiangsu Equity Exchange Center
• High-tech product recognition certificates for: four-high finishing line rolls, medium bar rolls, rolls for metal rolling mills, and flat steel rolls

ISO 9001 covers quality management, ISO 14001 covers environmental management, and ISO 45001 covers occupational health and safety. Together they indicate that the company has documented management systems in these areas, which is often a baseline requirement for industrial suppliers. The high-tech product certificates relate to specific roll applications rather than the company as a whole.

What to Verify Before Ordering

The website provides company-reported figures and certificate images. Before placing an order, confirm:

1. Current certificate validity — request copies with issue and expiry dates, and check the certification body.
2. Actual available capacity — the 38,000-ton figure is a stated maximum, not a committed monthly output.
3. Specification match — roll dimensions, material grade, and hardness requirements should be confirmed against your mill's parameters.
4. Lead times and references — ask for delivery schedules and, where possible, contact existing customers in your region or application.
