Great Wall ：Leading Global Innovation in Steel Structure Bridges And Modular Construction

Changchun Heavy Industry Steel Structure Co., Ltd., a leading company specializing in the manufacturing of steel structure bridges and modular construction, has earned widespread recognition from both domestic and international clients for its outstanding technical capabilities and stringent quality control. We are dedicated to providing efficient, safe, and aesthetically pleasing bridge solutions that meet the diverse needs of modern infrastructure projects.

1. Professional design team and advanced design standards

Changchun Heavy Industry Group has a professional design team led by professors from prestigious universities, capable of providing customized design solutions tailored to project needs. We use advanced international steel structure bridge design software and adhere strictly to international standards such as AISC 5400 (American Steel Institute), BS 5400 (British Standards Institution), and AS 5100 (Australian Standards) to ensure the safety and stability of our bridge structures. This high-standard design philosophy ensures that our products maintain a leading position in both domestic and international markets.

2. High quality raw materials and international certification  

Our raw materials are sourced from major international steel mills, such as the Bilei Steel Plant in Belgium. These materials comply with multiple international standards in Europe, the United States, and Australia, including ASTM in the U.S., EN 10025 in Europe, and AS/NZS in Australia. Not only do these materials exhibit excellent mechanical properties, but they have also been rigorously tested by third-party certification bodies like SGS, CCIC, and CNAS, ensuring their reliability and durability in practical applications.

3. World leading welding technology

Welding is a critical component in the construction of steel structure bridges. Great Wall Heavy Industry employs welding techniques that comply with European, Australian, and American standards, with the highest standard being the American Welding Society (AWS) 1.5 standard. These techniques also meet the European standard EN 1090 CE-DoP and other relevant international specifications. Our welding processes not only meet the world's most stringent welding requirements but have also been certified by BV French, ensuring that our welding quality reaches international top-tier standards.

4. Modular manufacturing and efficient construction  

Changchun Heavy Industry's steel structure bridges are manufactured using a modular approach, enabling rapid assembly and efficient construction. Our 321-type Berre steel bridge and 200-type Berre bridge have been successfully applied in numerous large-scale projects. We have established a complete production line for these bridges, with an annual output exceeding 10,000 tons. Additionally, we have developed a large-span prefabricated D-type bridge, capable of spanning up to 91 meters. This bridge has completed load testing and engineering applications, demonstrating outstanding practical capabilities.

5. Rich surface treatment process

To ensure the long-term service life of steel structure bridges, Great Wall Heavy Industry has equipped a variety of surface treatment processes, including sand treatment, dip coating, spray painting, hot-dip galvanizing, and zinc-aluminum alloy coating. These processes not only enhance the corrosion resistance of the bridge but also improve its aesthetic appeal, making it more attractive in urban landscapes.

6. Superior geographical location and logistics advantages

Changchun Heavy Industry, located in Zhenjiang City, Jiangsu Province, is situated in the Yangtze River Delta economic zone, with convenient transportation and a well-developed logistics network.
