Stainless Steel Heavy Calbe Bailey Bridge / Galvanized Steel Bailey Bridges 4.2m Width

Stainless Steel Heavy Calbe Bailey Bridge/galvanized Steel Bailey Bridges

Jiangsu Zhonghai Bridge Equipment Co., Ltd. ensures the quality of Bailey bridges through a variety of measures, which cover all aspects from the production process to the final inspection:

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 is tested by SGS to ensure that it fully complies with American and European standards. The main welds are ultrasonically tested to ensure that they fully comply with welding standards. In addition, the Bailey bridges produced by the company have been tested by professional testing agencies and fully meet the design standards.

3. **Advanced production technology**
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.

4. **Standardized production**
The company's core product, the prefabricated highway steel bridge (Bailey Bridge), is processed and manufactured in accordance with the standards of the "Technical Specifications for Highway Bridge and Culvert Construction" (JTJ041-2008) issued by the Ministry of Transport. This standardized production ensures that the quality and performance of the product meet national and industry standards.

5. **Continuous technological innovation**
The company focuses on 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 the above measures, Jiangsu Zhonghai Bridge Equipment Co., Ltd. ensures the high quality and reliability of its Bailey bridge products and has won wide recognition in domestic and foreign markets.
