Leading the future of transportation construction with modular steel bridge technology

In today's rapidly advancing urbanization process, bridges, as critical infrastructure connecting cities with cities and villages with villages, are becoming increasingly prominent in importance. Steel structure bridges, owing to their advantages such as lightweight yet high strength, convenient construction, and excellent durability, are gradually becoming the mainstream choice in modern bridge construction. The Great Wall Enterprise, as a high-tech company specializing in the research, development, and manufacturing of steel structure bridges, is committed to providing global clients with high-quality, high-efficiency steel structure bridge solutions by leveraging its outstanding capabilities in design, materials, welding, and certification.

1. The Core Advantages of Great Wall Enterprise

(1) Professional design team and international standard support

Great Wall Enterprise possesses a professional design team led by renowned professors from prestigious domestic and international universities. The team members not only possess profound theoretical knowledge in engineering but also have extensive practical experience. In the design process, Great Wall Enterprise consistently adheres to the design philosophy of "people-oriented, safety-first," ensuring that each steel structure bridge meets functional requirements while balancing aesthetics and practicality.  

Regarding design standards, Great Wall Enterprise strictly complies with internationally recognized specifications, including the American AISC (American Institute of Steel Construction) standards, the European EN 1090 standards, and the Australian AS 5100 standards. These standards not only cover requirements for the safety, stability, and durability of bridge structures but also impose stringent regulations on welding processes and material properties. By adopting these international standards, Great Wall Enterprise ensures the applicability of its steel structure bridges in different countries and regions, providing clients with broader opportunities for collaboration.

(2) The raw materials are sourced from top-tier international steel mills and comply with mainstream global standards.

The raw materials used for the steel structure products of Great Wall Enterprise are sourced from globally renowned large-scale steel mills, such as Germany's Bilei Steel Mill. These steel mills possess world-leading processes and technologies in steel production, capable of providing high-purity, high-uniformity steel materials to ensure stable quality of the final products. Moreover, the steel materials utilized by Great Wall Enterprise not only comply with international standards but have also passed multiple international certifications, such as ASTM (American Society for Testing and Materials), EN 10025 (European Standard), AS/NZS 3000 (Australian Standard), ensuring the applicability of its products across different countries and regions.

(3) The welding process complies with the highest global standards, ensuring structural safety.

Welding is a critical process in the manufacturing of steel structure bridges, with its quality directly impacting the overall performance and service life of the bridges. The welding techniques adopted by Great Wall Enterprise comply with the highest global welding standard—AWSD 1.5 (American Welding Society Standard), which imposes extremely stringent requirements on the strength, toughness, corrosion resistance, and other properties of welded joints. By adhering to this standard, Great Wall Enterprise ensures the safety and stability of its steel structure bridges under various complex working conditions.  

Additionally, Great Wall Enterprise has obtained the EN 1090 CE-DoP certification, a prestigious European authority on welding quality for steel structure enterprises. This certification signifies that Great Wall Enterprise has achieved internationally advanced levels in welding techniques and quality control.

(4) Modular design enhances construction efficiency and cost-effectiveness.

The Great Wall Enterprise adopts a modular design concept, dividing steel structure bridges into multiple standardized modules, each of which can be independently manufactured, transported, and installed. This design not only significantly shortens the construction cycle but also reduces construction costs and improves construction efficiency. The advantage of modular design lies in its flexibility to adapt to different terrains and geological conditions while minimizing on-site welding work and lowering construction risks.  

Furthermore, modular design offers excellent repeatability, enabling the rapid replication of the same bridge model across different projects, thereby achieving optimal resource allocation. This design philosophy not only enhances construction efficiency but also provides customers with more economical and environmentally friendly solutions.

(5) Advanced production equipment and quality management system

Great Wall Enterprise possesses advanced production equipment and a comprehensive quality management system, ensuring that each steel structure bridge meets the highest standards. The company is equipped with a full set of automated production lines, including cutting, welding, painting, hot-dip galvanizing, and other processes, enabling full-process automated control from raw materials to finished products. Additionally, the company has obtained ISO 9001 quality management system certification, with its welding processes and welders certified by BV (Bureau Veritas). Raw materials and finished products have passed inspections by third-party certification bodies such as SGS, CCIC, and CNAS, ensuring the competitiveness of its products in the international market.

1. Product and Technological Highlights of Great Wall Enterprise

(1) Type 321 Bailey Steel Bridge: The Integration of Classic and Innovation

The Bailey bridge is a common prefabricated steel bridge structure widely used in bridge construction due to its simple structure, strong adaptability, and excellent interchangeability. However, traditional Bailey bridges have certain limitations in span, typically reaching only about 60 meters. To overcome this issue, the Great Wall Enterprise introduced the Type 321 Bailey steel bridge, which achieves a single-span length of up to 91 meters through the use of larger steel sections and more optimized structural design, significantly enhancing the bridge's load-bearing capacity and construction efficiency.  

The Type 321 Bailey steel bridge not only features structural optimizations but also incorporates innovations in manufacturing processes. The company possesses a complete production line for entire bridges, enabling efficient production from raw materials to finished products. Additionally, this bridge exhibits excellent seismic and wind resistance performance, making it suitable for various complex terrains and climatic conditions.

(2) Long-span Prefabricated D-Shaped Bridge: Breaking Traditions, Leading the Future

On the basis of traditional Bailey bridges, Great Wall Enterprises has further developed the large-span prefabricated D-type bridge. This bridge adopts larger section steel and a simpler structural design, retaining the prefabricated advantages of Bailey bridges while breaking through their span limitations. The single-span length of the D-type bridge can reach 91 meters, making it one of the largest-span prefabricated steel bridges currently on the market.

The D-type bridge has not only been structurally optimized but also innovated in manufacturing processes. Through load tests and engineering applications, the company has verified the stability and reliability of this bridge. Additionally, the D-type bridge features excellent construction efficiency and cost-effectiveness, enabling it to meet the demands of various projects.
