Strict Manufacturing Process and Quality Assurance

Strict Manufacturing Process and Quality Assurance

The Superior Quality of Our Reinforced Welded Mesh is built upon a closed-loop, strictly controlled manufacturing process.

1. Raw Material Control We exclusively use high-carbon steel wire rod  Complies with SD420, SD500 and above standards. Each batch is accompanied by complete Mill Certificates (CO/CQ).

2. Automated Processing & Welding The steel is straightened, precision-cut, and fed into CNC-controlled automatic welding machines. Computerized control ensures optimal strength at every weld point and grid spacing accurate to the millimeter.

3. Surface Treatment Based on project requirements, products are supplied either as standard black steel or with Hot-Dip Galvanizing, which multiplies corrosion resistance for use in harsh environments.

4. Multi-Stage Quality Inspection Mechanical Property Test: Weld shear strength tests are conducted to ensure compliance with GB/T 1499.3 or equivalent international standards. Dimensional Check: Wire diameter and grid spacing are meticulously measured and verified. Visual Inspection: Panels with deformation or poor welding are rejected.

5. Packing & Dispatch Final products are securely bundled, clearly labeled, and carefully protected against moisture and damage during transport and storage. Thanks to this closed-loop process, every panel we produce guarantees high reliability, forming the foundation for all robust structures. Our high-quality product is suitable for a wide range of applications. Need detailed technical specifications? Contact us now to obtain a sample test report.
