Jiangsu Zhonghai Bridge Equipment Co., Ltd.'s quality control process is in the leading position in the industry, in line with international standards, and even exceeds the industry average in some aspects.

In line with industry standards
- **ISO 9001:2000 certification**: The company has successfully passed the ISO 9001:2000 international quality system certification. This certification is a widely recognized quality management standard internationally, requiring companies to establish a strict quality management system to ensure the quality of products and services. Passing this certification shows that the company has met international standards in quality control and can provide customers with products and services that meet international standards.
- **Ultrasonic flaw detection**: The company conducts ultrasonic flaw detection on all major welds to ensure that the quality of the welds meets the 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.
- **SGS testing**: In order to meet the needs of the international market, the company's exported steel products are all tested by SGS to ensure that they fully comply with American and European standards. SGS is an internationally recognized inspection, identification, testing and certification organization with strict inspection standards. Products that pass SGS inspection have higher recognition in the international market.

Beyond the industry average
- **Automatic welding robot technology**: The company is the first domestic enterprise to achieve fully automatic welding of Bailey bridges. By introducing automatic welding robot technology, the company not only improves production efficiency, but also significantly reduces human errors, so that the welding accuracy is controlled within 0.3 mm. This high-precision welding technology is at the leading level in the industry, ensuring the stability and consistency of product quality.
- **Strict quality supervision and inspection**: 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. This strict quality supervision mechanism is relatively rare in the industry and reflects the company's high attention to product quality.
- **Continuous technological innovation**: The company continues to accelerate the company's scientific and technological innovation capabilities, focusing on corporate technology research and development, production processes and product detail optimization. Through technological innovation, the company has not only improved product quality, but also improved production efficiency, further consolidating its position in the industry.

Summary
Jiangsu Zhonghai Bridge Equipment Co., Ltd. has passed strict ISO 9001:2000 quality management system certification, ultrasonic flaw detection, SGS testing and other measures to ensure that product quality meets international standards. At the same time, the company has introduced automatic welding robot technology, strict supervision and inspection mechanisms and continuous technological innovation, making its quality control leading in the industry, even surpassing the industry average in some aspects.
