Quality Control & Global Certifications
Quality is the cornerstone of our operations. Certified to ISO 9001, we have established a comprehensive quality control system spanning the entire production process:
• Material Selection: We source high-performance alloy steels (e.g., 40CrMo, 45CrMnTi) and enforce strict testing for chemical composition and mechanical properties (tensile strength, impact toughness, etc.).
• Process Oversight: Critical components undergo in-house non-destructive testing (NDT), hardness checks, and rated load verification to ensure performance compliance.
• Traceability: Full batch tracking from raw material incoming to final delivery guarantees transparency and accountability.
Today, over 95% of our products meet or exceed international standards (CE, ASTM, ISO), earning widespread recognition in global markets.
