Shandong Daming Breaks New Ground with Ultra-Narrow Flat Steel Bar Production

Innovation meets precision as one of Daming Group’s core steel processing centers achieves a new milestone in custom steel manufacturing.

In a breakthrough that reinforces its position as a leader in precision steel processing, Shandong Daming, one of the eleven advanced steel processing centers under Daming Group, has successfully produced its first batch of ultra-narrow flat steel bars—measuring only 70 mm in width. This marks a critical advancement in non-standard steel customization and expands the group’s processing portfolio to meet specialized industrial needs.

Flat Steel Bars: A Backbone of Industrial Manufacturing

Flat steel bars are foundational components in countless industrial applications. Known for their uniform shape, high strength, and versatility, flat bars are widely used in construction, machinery, shipbuilding, renewable energy, transportation, and the manufacturing of heavy equipment. Typically, these products range in width from 100 mm to 500 mm, with standardized processing techniques to ensure dimensional consistency and load-bearing strength.

However, as industrial demands shift toward smaller, lighter, and more precise components, the market for ultra-narrow flat steel bars has emerged—requiring advanced processing capabilities and highly customized solutions.

Pushing Limits for a Strategic Client

Shandong Daming has long been recognized for delivering premium flat steel products with widths above 100 mm, consistently winning praise for precision, finish quality, and service reliability. Recently, a long-standing customer—a machinery manufacturer based in Jining, Shandong—approached the company with a special request: 70 mm wide flat bars, a specification far narrower than what Daming’s existing production lines were designed to handle.

Rather than view the request as a limitation, Shandong Daming saw it as an opportunity to innovate—and to reinforce its commitment to supporting strategic customers with tailored solutions.

“Customer expectations are our goals,” said an operator from Shandong Daming. “When we say we support customization, we mean it—even if it means pushing the limits of our equipment.”

Precision Engineering: From Concept to Success

To fulfill the order, Shandong Daming mobilized a specialized technical task force, bringing together experts in process engineering, mechanical design, and front-line production. The team initiated a rigorous R&D and testing cycle that included:

• Advanced simulation modeling to evaluate mold stress, material deformation, and thermal behavior;
• Experimental toolpath planning and optimization of feed rates to find the best-fit processing window;
• Adaptive retrofitting of existing production equipment to support the narrower width range.
• Skilled technicians provide real-time operational control to manage vibration, alignment, and consistency.

Overcoming numerous engineering and material challenges, the team ultimately succeeded in establishing a repeatable, high-precision process capable of delivering ultra-narrow flat bars with outstanding quality.

Surpassing Expectations

Testing of the initial batch of 70mm flat steel bars revealed exceptional results: dimensional tolerance, surface finish, straightness, and edge integrity all met — and in many cases, exceeded — customer specifications. The client has since confirmed that the ultra-narrow steel bars have improved the performance, integration, and market competitiveness of their machinery products.

“This project demonstrates the strength of Shandong Daming and, by extension, the broader Daming Group,” said a senior engineer involved in the project. “We’re not just delivering a product—we’re delivering a competitive edge.”

A Strategic Asset within the Daming Group

As one of Daming Group’s eleven state-of-the-art steel processing centers, Shandong Daming plays a critical role in the group’s nationwide network of service and production facilities. With access to shared R&D resources, advanced equipment platforms, and a coordinated supply chain, Shandong Daming is uniquely positioned to offer flexible, scalable, and high-precision steel solutions.

This successful ultra-narrow flat bar project adds to the group’s growing portfolio of non-standard, customized, and high-difficulty processing capabilities, further strengthening its leadership in the steel service industry.

Looking Ahead

Shandong Daming’s success is not just a milestone for one factory—it’s a reflection of the Daming Group’s broader innovation-driven strategy. As global industries continue to evolve toward higher standards of precision, weight reduction, and structural efficiency, Daming’s network of processing centers is prepared to meet the challenge.

With this achievement, Shandong Daming is poised to support even more specialized, high-value projects—delivering technical solutions that are both forward-looking and deeply grounded in the company’s manufacturing expertise.
