How Does Samsink Verify the Material Used in Stainless Steel Sinks?

Samsink ensures material authenticity for every stainless steel sink by requiring Mill Test Certificates (MTC) for all raw materials. In addition, Samsink conducts on-site verification using a handheld PMI (Positive Material Identification) spectrometer to confirm the exact grade (SUS304/SUS316), guaranteeing superior corrosion resistance and long-term durability of each stainless steel sink.
