We work closely with certified steel mills to confirm specifications before procurement. Upon arrival, all stainless steel materials undergo dimensional checks, surface inspections, and PMI (Positive Material Identification) analysis to ensure compliance before entering production.

Our QC department is equipped with calipers, thread gauges, pressure testers, surface roughness testers, and PMI analyzers, operated by trained professionals. All instruments undergo regular calibration to maintain accuracy and consistency.

Non-conforming products are clearly labeled, isolated, and securely stored to eliminate the risk of mixing with qualified products, ensuring only compliant goods are shipped.
