Space Steel Prefabricated Pedestrian Bridges Galvanized Modular Steel Bridge

Space Steel Structure Pedestrian Bridge/steel Bailey Pedestrian Bridge

Jiangsu Zhonghai Bridge Equipment Co., Ltd. takes a variety of measures to ensure that product quality meets international standards:

1. **Strict quality supervision and inspection**
All the company's products are strictly supervised and regularly inspected by the General Armament Department's scientific research station 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.

2. **International standard testing**
In order to meet the needs of the international market, the company's exported product steel has been professionally tested by SGS to ensure that it fully complies with American and European standards. SGS is an internationally recognized inspection, identification, testing and certification agency with strict inspection standards. Products that pass SGS inspection have higher recognition in the international market.

3. **Ultrasonic flaw detection**
All major welds are ultrasonically inspected to ensure that they fully comply with welding standards. This detection method is a relatively strict detection method in the industry, which can effectively detect potential defects in welds and ensure the safety and reliability of bridge structures.

4. **Testing by professional testing agencies**
The Bailey bridges produced by the company have been tested by professional testing agencies and fully meet the design standards. This further ensures the quality and safety of the products, enabling them to meet the needs of different countries and regions.

5. **Technological innovation and automated welding**
The company has introduced automatic welding robot technology to ensure that the connection of each welding part is accurate and correct, and the welding accuracy is controlled within 0.3 mm. This high-precision welding technology not only improves production efficiency, but also significantly reduces human errors, making product quality more stable and consistent.

6. **Continuous technological innovation**
The company pays attention to technological innovation and has successfully applied for a number of invention patents and utility model patents. The application of these patented technologies not only improves the quality and performance of the products, but also enhances the company's competitiveness in the market.

Through these measures, Jiangsu Zhonghai Bridge Equipment Co., Ltd. ensures the high quality and reliability of its products and has won wide recognition in domestic and foreign markets.
