Production advantages of Jiangsu Zhonghai Bridge Equipment Co., Ltd.

Jiangsu Zhonghai Bridge Equipment Co., Ltd. (hereinafter referred to as "Zhonghai Bridge") has established significant production advantages in the field of bridge equipment manufacturing with its strong technical strength, advanced production equipment and strict quality control system.

Advanced production technology
Zhonghai Bridge is the first domestic enterprise to achieve fully automatic welding of Bailey bridges. By introducing automatic welding robot technology, the company not only improved production efficiency, but also significantly reduced human errors, so that the welding accuracy is controlled within 0.3 mm. This high-precision welding technology ensures the stability and consistency of product quality, further consolidating its leading position in the industry.

Strict quality control
All products of the company are strictly supervised and regularly inspected by the scientific research station of the General Armament Department to ensure that each product meets strict quality standards. In addition, the company has successfully passed the ISO9001:2000 international quality system certification and was awarded the honorary title of quality system management demonstration unit by the China Quality Observation Station. In order to meet the needs of the international market, the steel products exported by the company are all tested by SGS to ensure that they fully comply with American and European standards.

Strong R&D Capabilities
China Ocean Bridge invests 15 million yuan in technology research and development every year, and R&D investment accounts for more than 10%. As of now, the company has 29 valid utility patents and 2 invention patents, and another 12 patents are being applied for. The company has also successfully applied for invention patents for the production process of prefabricated highway steel bridges and utility model patents for its products.

Efficient production process
Through intelligent transformation, the production efficiency of China Ocean Bridge has been significantly improved. In the past, a production line required 16 people to operate, but now only 3 people are needed to complete the entire process, and the efficiency has increased several times. This efficient production process not only improves production efficiency, but also reduces production costs and enhances the company's market competitiveness.

Wide market application
China Ocean Bridge's core product, prefabricated highway steel bridges (Bailey bridges), are widely used in domestic and foreign infrastructure construction, national defense preparedness, emergency rescue and other fields. The company has participated in many large-scale international projects, such as the Maldives China-Maldives Friendship Bridge, Brunei Cross-Sea Bridge, Pakistan Hub Power Station, Kenya Nema Railway, Malaysia East Coast Railway, etc. These successful cases fully demonstrate the technical strength and profound experience of Zhonghai Bridge in large-scale infrastructure projects.

In summary, Jiangsu Zhonghai Bridge Equipment Co., Ltd. has established significant production advantages in the field of bridge equipment manufacturing with its advanced production technology, strict quality control, strong R&D capabilities and efficient production processes. These advantages not only enhance the company's market competitiveness, but also provide high-quality products and services for domestic and foreign infrastructure construction.
