China Sea Bridge Introduction

Jiangsu Zhonghai Bridge, located in the Dantu High-tech Industrial Park of Zhenjiang, has been a benchmark in the prefabricated highway steel bridge (Bailey bridge) field for over two decades. With a registered capital of 55 million yuan, an annual production capacity of 60,000 tons, it maintains a leading position among the giants of prefabricated highway steel bridge manufacturing in East China.

China Sea Bridge Company, driven by technological innovation, has established a dedicated research and development center for prefabricated highway steel bridges to focus on core technology breakthroughs. It has constructed an integrated one-stop service model covering "survey - design - production - logistics - installation guidance" throughout the entire industrial chain. With its end-to-end efficient collaborative capabilities, the company has helped to shorten project duration by an average of 40%. Relying on the first domestically developed fully automatic welding production line for Bailey girder sheets, the company achieves zero defect control in welding quality, with production efficiency several times higher than traditional methods, while significantly reducing labor costs. The independently developed 450-type Bailey Bridge, with a single span of 81 meters and a carrying capacity of 90 tons, fills the domestic technological gap in long-span heavy-load steel bridges. It also promises a century-long service life with rigorous manufacturing standards, showcasing the company's technical strength and quality credibility.

Products are certified by authoritative bodies such as ISO9001 and EU CE, and tested by international organizations like CNAS, TUV, and SGS. They cover the 321, 200, and 450 models of Bailey Bridges and steel support systems, and are widely used in emergency relief, transportation infrastructure, and other fields.

As a high-tech enterprise and a specialized, innovative, and unique enterprise, the company holds multiple patents, operates in more than 20 countries and regions around the world, and participates in major projects such as the Hangzhou Bay Bridge, the Shenzhen-Zhongshan Channel, and the Sichuan-Tibet Railway. Overseas projects cover “1With 1st RoadMultiple nodes. In the future, the company will continue to empower intelligent manufacturing, creating a world-class benchmark enterprise for bridge equipment, connecting Chinese standards with the world.
