Simple Steel Truss Bridge/light Steel Truss Bridge
Jiangsu Zhonghai Bridge Equipment Co., Ltd. strictly follows international standards for SGS testing to ensure the quality of its exported products. The following are the specific standards that the company follows in SGS testing:
1. **Material testing standards**
- **Steel testing**: The steel products exported by the company are all tested by SGS to ensure full compliance with American Standards (ASTM) and European Standards (EN). These standards cover the chemical composition, mechanical properties, dimensional tolerances and other aspects of steel to ensure the high quality and reliability of the materials.
- **Welding material testing**: Welding materials are also strictly tested, including welding rods, welding wires and fluxes, to ensure that the quality of materials during the welding process meets international standards.
2. **Welding quality testing standards**
- **Ultrasonic flaw detection**: All major welds are tested by ultrasonic flaw detection to ensure that the quality of the welds fully meets the welding standards. This detection method can effectively detect potential defects in welds, such as cracks, pores and lack of fusion, to ensure the safety and reliability of bridge structures.
- **Welding process inspection**: The welding process is also strictly inspected by SGS to ensure that the welding process meets international standards, including the control of welding parameters, the calibration of welding equipment and the qualifications of welding personnel.
3. **Overall product inspection standards**
- **Structural integrity inspection**: SGS inspects the overall structure of the Bailey bridge to ensure that its design and manufacturing meet international standards. This includes inspections of the bridge's bearing capacity, stability, durability and other aspects to ensure the safety and reliability of the bridge under various conditions of use.
- **Surface treatment inspection**: The surface treatment of the bridge is inspected to ensure that its anti-corrosion performance meets international standards. This includes inspections of the thickness of the galvanized layer of steel, the adhesion of the coating and other aspects to ensure the durability of the bridge in harsh environments.
4. **Certification and report**
- **SGS certification**: SGS certifies products according to international standards and issues authoritative inspection reports. These reports are widely recognized worldwide and provide a strong quality guarantee for the company's export products.
- **Declaration of Conformity**: The SGS test report contains a declaration of conformity, which clearly states the international standards that the product complies with, such as American Standard (ASTM) and European Standard (EN).
Through the above strict testing standards and certification processes, Jiangsu Zhonghai Bridge Equipment Co., Ltd. ensures that its export products have high quality and high reliability in the international market, and has won wide trust from customers.
