Materials First, Quality Foremost – The Raw Material Assurance System of Great Wall  Industry

In today's increasingly competitive global industrial environment, material selection and quality control have become critical factors determining the success or failure of products. Great Wall Heavy Industry, as an enterprise specializing in the research, development, and manufacturing of steel structure products, consistently adheres to the core philosophy of "material as the foundation, quality as the priority," committed to creating truly "world-class" steel structure products. We are well aware that only by controlling material quality at the source can the performance and reliability of the final product be ensured. Therefore, all raw materials used by Great Wall Heavy Industry are sourced from large international steel mills, such as Belgium's Bilei, ensuring high purity and stability of the materials. The steel used complies with international standards such as the American ASTM, European EN 10025, and Australian AS/NZS, providing a solid guarantee for the safety and durability of bridge structures.

1. International-level raw material supply guarantee systemI. International-Level Raw Material Supply Assurance System

The raw material guarantee system of Great Wall Heavy Industry serves as the cornerstone of its product quality. We rigorously screen suppliers to ensure all raw materials are sourced from globally leading steel manufacturers, such as Belgium's Bilei, guaranteeing high purity and stability of the materials. These steels not only comply with international standards but also possess excellent mechanical properties and corrosion resistance, meeting the usage requirements in diverse environments. For instance, the steels we adopt conform to international standards such as ASTM in the United States, EN 10025 in Europe, and AS/NZS in Australia, ensuring compatibility and reliability when applied across different countries and regions.

In terms of material selection, Changcheng Heavy Industry not only focuses on the physical properties of materials but also emphasizes the stability of their chemical composition. Through rigorous testing procedures, we ensure that each batch of raw materials complies with international standards and undergoes inspections by third-party certification bodies such as SGS, CCIC, and CNAS, further enhancing product reliability. This strict control over materials not only improves the overall quality of our products but also provides customers with more dependable choices.

2. Digital Twin Technology Facilitates Product Lifecycle Management

In the design and manufacturing process of steel structure products, the application of digital twin technology has brought revolutionary changes to Changcheng Heavy Industry. We automatically adapt to AS5100/BS5400 standards through parametric modeling to ensure designs comply with international specifications. Simultaneously, we utilize digital twin technology to simulate full lifecycle operation and maintenance, achieving comprehensive digital management from design to construction and maintenance.

The application of digital twin technology not only enhances the accuracy of design but also provides real-time data support for construction and operation and maintenance. Through digital twin models, we can simulate different construction plans and operation and maintenance strategies, evaluate their effectiveness, and provide optimal decision-making support for operation and maintenance teams. This data-driven intelligent decision-making helps reduce operation and maintenance costs, improve equipment utilization, and achieve sustainable and stable operation of steel structure products.

3. Professional Design Team and International Standard Certification

Great Wall Heavy Industry possesses a professional design team led by renowned university professors, who not only have extensive engineering experience but are also well-versed in international design standards. We adopt global standards such as the American AISI, European BS5400, and Australian AS5100 to ensure the scientific and forward-looking nature of our designs. Additionally, we are equipped with specialized steel structure bridge software, enabling efficient completion of complex structural design and optimization.

In terms of welding technology, Changcheng Heavy Industry adopts high-precision welding techniques that comply with European, Australian, and American standards, such as AWSD1.5 (the highest welding standard in the world) and EN1090 CE-DoP, ensuring the stability and reliability of welding quality. Through strict welding process control, we guarantee that every weld seam meets international standards, thereby enhancing the overall performance of our products.

4. Modular Design and Efficient Production

The steel structure products of Changcheng Heavy Industry adopt modular design, which not only enhances production efficiency but also reduces construction difficulty. Our Model 321 Bailey steel bridge and Model 200 prefabricated highway steel bridge both utilize modular design for easy transportation and installation, making them suitable for various complex terrains and environments. Additionally, we have developed a large-span prefabricated Type D bridge with a single span reaching up to 91 meters, which has completed full-scale load testing and engineering applications.

The advantage of modular design lies in its ability to not only enhance construction efficiency but also reduce construction costs. Through modular production, rapid assembly and disassembly can be achieved, thereby shortening project timelines and improving construction efficiency. Additionally, modular design facilitates easier maintenance and replacement, extending product lifespan and enhancing overall economic benefits.

5. Intelligent Operation and Maintenance and Full Lifecycle Management

During the operation and maintenance phase of steel structure products, Changcheng Heavy Industry also employs advanced digital twin technology to achieve intelligent operation and maintenance throughout the entire lifecycle. Through the digital twin model, we can monitor equipment operating status in real time, predict potential failures, and conduct maintenance in advance, thereby extending equipment service life and reducing operation and maintenance costs.

The application of digital twin technology not only enhances the intelligence level of operation and maintenance but also provides customers with more precise operation and maintenance services. Through digital twin models, we can simulate different operation and maintenance scenarios, evaluate their effectiveness, and offer customers optimal operation and maintenance recommendations. This data-driven intelligent decision-making helps improve operation and maintenance efficiency and achieves the sustainable development of steel structure products.

6.  Future Prospects

Looking ahead, Great Wall Heavy Industry will continue to deepen the philosophy of "material foundation, quality first," constantly elevating the level of its raw material assurance system to ensure every batch of materials meets international standards. Simultaneously, we will further promote the application of digital twin technology to achieve full-process digital management from design to construction and operation & maintenance, thereby enhancing the intelligent level of our products.

We will continue to strengthen cooperation with renowned universities and research institutions both domestically and internationally to promote technological innovation in steel structure products and enhance their international competitiveness. By continuously optimizing production processes and improving product quality, we are committed to providing customers with superior products and services, striving to create truly "world-class" steel structure products.

Conclusion  

Quality begins with materials. Great Wall Heavy Industry consistently adheres to this principle, creating truly "world-class" steel structure products through a rigorous raw material assurance system, advanced digital twin technology, a professional design team, and efficient modular production. We firmly believe that only by controlling material quality at the source can we ensure the performance and reliability of the final product. Moving forward, we will continue striving to enhance product quality, provide customers with superior products and services, and promote the sustainable development of the steel structure industry.
