Hubei Daming Delivers Millimeter-Level Precision in Bridge Steel Components

Recently, Hubei Daming, one of Daming International’s eleven steel processing centers, completed a demanding fabrication project for a renowned bridge construction company. Through advanced processing technology, high-end equipment, and exceptional teamwork, Hubei Daming overcame multiple precision manufacturing challenges — ensuring the flawless delivery of several critical bending structural components that form the “steel bones” of large-scale bridges.

This achievement once again demonstrates Daming’s strength in high-end metal component processing and its unwavering commitment to empowering national infrastructure with intelligent manufacturing excellence.

Precision at the Millimeter Level: Tailoring the Bridge’s Structural Skeleton

The project involved low-alloy, high-strength steel components with thicknesses of 8 mm and lengths ranging from 5 to 9.2 meters. Serving as essential structural elements, these components form the internal framework of the bridge — playing a key role in force transmission and structural stability.

However, the project presented three major challenges:

• High Risk of Mold Interference – The large bending radius and complex geometries required extremely precise mold alignment. Even the slightest offset could cause surface damage or bending failure.

• Stringent Flatness Requirements – Each part needed to integrate seamlessly during assembly. Minor deviations could compound during on-site installation, affecting overall stability and safety.

• Zero-Tolerance Splicing Accuracy – Each joint required “zero-tolerance” precision, demanding exceptional control throughout the entire preprocessing stage.

Every millimeter truly mattered.

Technological Breakthroughs: Where Power Meets Precision

To meet these challenges, Hubei Daming formed a dedicated technical task force comprising experts from its process and production departments. The team developed a customized solution that integrated multi-equipment coordination, digital simulation, and real-time precision control to ensure perfect execution.

• Multi-Equipment Collaboration
  Utilizing its complete suite of press machines — including 600T, 1000T, and 2000T models — Hubei Daming assigned each machine according to the specific force and shape requirements of the components. This “force follows shape” approach ensured optimal forming conditions for every section.

• Accurate Mold and Parameter Matching
  Through repeated digital simulations and trial bending, the team fine-tuned mold selection, bending sequences, and feed speeds. These refinements effectively eliminated potential interference points and ensured smooth, uniform bending lines.

• Real-Time Quality Control
  From blanking to forming, multiple checkpoints were established. Using high-precision measurement tools, technicians continuously monitored key parameters — dimensional accuracy, curvature, and flatness — consistently maintaining millimeter-level precision throughout production.

Quality and Efficiency Combined: Setting a New Benchmark

Thanks to rigorous process management, cutting-edge equipment, and deep technical expertise, Hubei Daming not only achieved exceptional dimensional accuracy but also completed the project ahead of schedule, surpassing industry averages in both quality and delivery.

The customer highly praised Daming’s precision, efficiency, and reliability, recognizing the company as a trusted partner in complex steel structure fabrication for major bridge projects.

Driving Continuous Innovation in Bridge Component Processing

With years of accumulated experience in bridge steel fabrication, Hubei Daming has developed strong capabilities in processing pretreatment materials, U-ribs, stiffeners, and curved components. Through continuous technological upgrading and digital process innovation, the company continues to refine its intelligent manufacturing systems and expand its service reach to more large-scale infrastructure projects.

Looking ahead, Hubei Daming remains committed to customer satisfaction, innovation-driven growth, and superior quality, contributing to the construction of more landmark bridges across China — and fully showcasing the strength of Daming Intelligent Manufacturing.
