Future new product plans of Jiangsu Zhonghai Bridge Equipment Co., Ltd.

Jiangsu Zhonghai Bridge Equipment Co., Ltd. (hereinafter referred to as "Zhonghai Bridge") has always maintained a positive attitude in technological innovation and new product development, and is committed to providing customers with higher quality products that are more adapted to market needs. The following are the company's future new product plans and R&D directions:

1. **R&D of new Bailey bridge**
Zhonghai Bridge is developing a 450-type Bailey bridge with a span of 83 meters and a load of 90 tons. The performance of this new Bailey bridge will surpass similar foreign products and can meet the overload passage needs of large-scale engineering construction and special vehicles. The product has simultaneously applied for three sets of Chinese, American and European standard certifications, aiming to further expand the global market.

2. **New products of high bending and shear resistance Bailey trusses**
The company has developed various new products of high bending and shear resistance Bailey trusses, which not only meet the load requirements of highway-I level, city-A level, HS25 (US load standard), HA (British load standard), etc., but also greatly exceed the overload passage of special vehicles after testing and actual use, and meet the optimal conditions for large-scale engineering construction.

3. **Modular and prefabricated construction products**
China Ocean Bridge will continue to optimize modular design and the production of prefabricated components to achieve rapid assembly at the construction site and shorten the construction cycle. This modular and prefabricated construction will further improve construction efficiency and quality.

4. **Application of intelligent and information technology**
With the continuous development of intelligent and information technology, China Ocean Bridge plans to apply BIM technology, Internet of Things technology, etc. more widely in bridge construction. This will enhance the level of refined management of the construction process and improve the quality and safety of the project.

5. **Green and environmentally friendly products**
China Ocean Bridge will be committed to developing green construction products, using environmentally friendly materials, energy-saving processes and recycling methods to reduce energy consumption and environmental pollution during construction and achieve sustainable development of bridge projects.

Through these new product plans and R&D directions, China Ocean Bridge will not only continue to consolidate its leading position in the domestic market, but will also further expand the international market, promote "Chinese standards", and make Chinese manufacturing shine on the international stage.
