Daming’s Edge in U-Shaped Steel

Hubei Daming has once again demonstrated its expertise in precision manufacturing with the successful delivery of nearly 600 pieces of critical U-shaped bent components for a major bridge manufacturer. Measuring 12 meters in length and 8mm in thickness, each component required a series of highly coordinated processes—including slitting, cut-to-length, cutting, and bending. This high-quality, high-efficiency delivery not only solved key technical challenges for the customer but also strengthened Daming’s reputation for engineering excellence.

01 Technical Challenge: From Basic Processability to High-Precision Control

Unlike conventional U-shaped manufacturing—where raw materials are directly planed and bent without stringent requirements for hole accuracy or flange control—this project introduced an entirely new level of complexity.

After leveling, round holes and custom openings had to be cut with exceptional precision. During bending, these holes needed to maintain perfect symmetry while ensuring that no flanges formed at the openings. This dual requirement significantly raised the bar for deformation control across the entire process chain.

Complicating matters further, the components initially produced by an outsourced supplier showed severe “sickle bends” during the cutting stage, which led to major edge buckling during bending. Determined to resolve the issue, the customer turned to Hubei Daming for a dependable, engineering-driven solution.

02 Process Innovation: Systematic Re-Engineering, Not Single-Point Fixing

Faced with the dual challenges of correcting sickle bends and preventing flange formation, Hubei Daming reframed the task—not as a simple repair job, but as a comprehensive, end-to-end process overhaul.

Hubei Daming implemented a three-tiered solution:

• Precise plate straightening to eliminate sickle bends at the source, preventing edge buckling during bending.

• Simultaneous control of hole accuracy and opening geometry, ensuring one-time bending that meets all deformation and tolerance requirements.

• Cross-departmental collaboration, aligning business, engineering, and production expertise to ensure meticulous quality control at every processing stage.

This systematic approach transformed a high-risk manufacturing challenge into a stable, repeatable, and quality-assured production workflow.

03 Project Impact: From Delivering Products to Delivering a Complete Methodology

This success story represents far more than a batch of high-quality U-shaped components—it is a breakthrough in methodology, setting a new engineering standard for complex U-shaped bending applications.

By providing a full-process, precision-controlled solution, Hubei Daming:

• Ensured seamless project execution for the customer

• Reduced overall project and production costs

• Demonstrated its commitment to innovation-driven problem solving

• Delivered a scalable method applicable to future high-difficulty structural components

This project not only showcases Daming’s ability to turn complex manufacturing problems into practical engineering solutions, but also reinforces its role as a trusted partner capable of empowering customer development through precision craftsmanship.

With this achievement, Hubei Daming has set a new industry benchmark for U-shaped machining and once again proven that its strength lies not only in producing parts—but in pioneering processes that move the entire industry forward.
