Strict adherence to ASME A112.19.3 and cUPC standards. We exclusively use POSCO SUS304 (18/8 Cr-Ni) stainless steel, verified by in-house salt spray tests to ensure superior corrosion resistance for every batch.
We invest over $100,000 annually in third-party audits and certifications. Our sinks are fully compliant with the rigorous plumbing codes of North America (USA & Canada) and Europe, ensuring risk-free procurement for our partners.
Compliant with ASME A112.19.3 / CSA B45.4
Mandatory for all plumbing projects in the US and Canada. Our sinks have passed strict drainage, thermal shock, and dimension tests.
Certified by SGS
Ensures traceability from raw material (steel coils) to final shipment. Every production step is documented and auditable.
Compliant with EN 13310:2015
Meets EU health, safety, and environmental protection standards for kitchen sinks, guaranteeing durability and cleanability.
We utilize advanced testing equipment to simulate years of daily usage. No product leaves our factory without passing these 4 critical performance tests.
From incoming material to final shipment, we implement a closed-loop quality system covering IQC, IPQC, FQC, and OQC to ensure zero defects.
Raw Material Inspection
Verification of POSCO SUS304 coils using spectrometers. We strictly measure for 16-18 Gauge thickness (tolerance ±0.02mm) to guarantee heavy-duty durability before raw materials enter our warehouse.
Production Monitoring
First-article inspection for every batch. We monitor hydraulic pressing depth and robotic welding seams every 2 hours to prevent batch defects during mass production.
100% Performance Test
Every sink undergoes a water leakage test and flatness check on a marble table. We also inspect the brushed satin finish for scratches or uneven textures under 800-lux lighting.
Packaging & Loading
Pre-shipment audit based on AQL 2.5 standards. We verify ISTA-3A drop-test compliance for carton packaging and ensure all accessories (grids/strainers) are correctly included.
