 Content Menu Technology leadership —— Global top standards build the backbone of the bridge

In the context of ongoing global infrastructure upgrades, steel structure bridges are becoming the preferred choice for modern bridge construction due to their lightweight, high strength, durability, and efficient construction. As a leading company in China's steel structure bridge industry, Great Wall Heavy Industry adheres to the core philosophy of' technology leadership and quality first,' dedicated to developing high-end steel structure products that meet international standards and global market demands. From design to production, from materials to processes, Great Wall Heavy Industry is grounded in global top-tier standards, continuously pushing the boundaries of technology, and infusing Chinese wisdom and strength into global bridge construction.

1. Top design team, leading global standards

Great Wall Heavy Industry boasts a design team led by professors from top Chinese universities, including Tsinghua University, Tongji University, and Southeast University. This team includes senior experts with deep theoretical knowledge in bridge engineering and extensive practical experience. They apply an international perspective to bridge design, ensuring that each steel structure bridge meets world-class standards in safety, durability, and aesthetics. In terms of design software, Great Wall Heavy Industry uses leading international tools such as MIDAS/CIVIL, SAP2000, and LUSAS. These tools support the mechanical analysis of complex structures and can simulate bridge behavior under various extreme conditions, ensuring the scientific and rational design. Additionally, the design team is compatible with American AASHTO, European BS5400, and Australian AS5100 standards, ensuring that products can be certified in different countries and regions, meeting global market demands.

2. high quality raw materials, strict quality control standards

Great Wall Heavy Industry understands that the quality of steel structure bridges starts with the selection of materials. To this end, the company has established long-term partnerships with leading global steel manufacturers, sourcing raw materials directly from international steel mills like Bilei, ensuring the stability and consistency of the materials. These steels not only meet global standards such as ASTM (American Society for Testing and Materials), EN (European Standard), and AS/NZS (Australian and New Zealand Standards), but also excel in welding performance, toughness, and weldability, reaching international advanced levels. In terms of welding technology, Great Wall Heavy Industry strictly adheres to the highest global standards, including ——AWSD1.5 (American Welding Society Standard) and EN1090 CEDoP (European Standard), ensuring that the weld quality meets international leading standards. By employing advanced welding techniques such as GMAW (Gas Metal Arc Welding), gas-electric vertical welding, and submerged arc welding, Great Wall Heavy Industry has achieved automation and intelligence in the welding process, significantly enhancing welding efficiency and quality stability.

3. Modular design to improve construction efficiency

In the construction of steel structure bridges, modular design is a key approach to enhancing construction efficiency and reducing project costs. Great Wall Heavy Industry widely applies the concept of modular design in its steel structure bridge projects, breaking down the bridge structure into multiple standardized, prefabricable modules. This allows for mass production in factories and rapid assembly at the construction site. This design not only shortens the construction period but also effectively reduces on-site risks and costs. Additionally, Great Wall Heavy Industry has integrated BIM (Building Information Modeling) and VR (Virtual Reality) technologies, using digital methods to create three-dimensional models and visualizations of the bridge structure. This enables the design team to identify potential issues in advance and optimize the design in a virtual environment. This technological integration not only enhances design accuracy but also provides precise guidance for subsequent construction.

4. intelligent manufacturing, to build high-quality steel structure Bridges

In the manufacturing process, Great Wall Heavy Industry has equipped itself with advanced automated production lines, achieving intelligent management from raw material processing to finished product assembly. The company has installed advanced equipment, including automatic welding robots, high-precision CNC cutting machines, and 3D inspection systems, ensuring that every step meets international standards. Additionally, the company has established a comprehensive quality management system, certified to ISO 9001 and ISO 14001, ensuring that its products meet international standards in quality, environmental protection, and safety. In terms of welding technology, Great Wall Heavy Industry has developed efficient welding techniques such as low-line-energy GMAW welding, intelligent gas-electric vertical welding, and deep-melt submerged arc welding, which have significantly improved welding efficiency and quality. These technologies are not only suitable for large bridge structures but are also widely used in complex engineering projects such as ports, airports, and industrial plants.

5. Global vision, serving the global market

Great Wall Heavy Industry's products not only serve the Chinese market but are also exported to numerous countries and regions, including Europe, America, Southeast Asia, and Africa. The company's products have been successfully used in world-class projects such as the Hong Kong-Zhuhai-Macao Bridge, Xihoumen Bridge, and墨西拿大桥, showcasing the outstanding performance and international competitiveness of China's steel structure bridges. In the overseas market, Great Wall Heavy Industry's products comply with international standards such as AASHTO, EN, and AS/NZS, and can smoothly pass key certifications such as the EU CE, US DOT, and Australian AS. The company actively participates in the formulation of international standards, maintaining close cooperation with international organizations like ASTM, EN, and AS, promoting Chinese standards to the world.

6. green construction to promote sustainable development

In the current global push for green and low-carbon development, Great Wall Heavy Industry actively supports the national 'dual carbon' strategy by promoting the green construction of steel structure bridges. The company uses high-performance steel to minimize material waste, optimizes welding techniques, and reduces energy consumption and carbon emissions. Additionally, the company is exploring the use of new eco-friendly materials like hemp concrete to provide more sustainable solutions for bridge construction. During construction, Great Wall Heavy Industry employs digital twin technology (Digital Twin) to monitor the deformation and stress of the bridge structure in real time, enabling precise control and intelligent maintenance. This technology not only extends the bridge's lifespan but also provides a scientific basis for its lifecycle management.

7.  Future outlook: Build a world-class steel structure bridge brand

Looking ahead, Great Wall Heavy Industry will continue to adhere to the philosophy of 'technology leadership and quality first,' continuously increasing investment in R&D, promoting technological innovation, and enhancing product competitiveness. The company plans to further expand its international market presence, enhance brand influence, and build a globally recognized steel structure bridge brand over the next few years.
