Zero-Defect Quality Mandate

Quality Control & Needle Detection Systems

Quality is not an afterthought at QZSTREETWEAR. With 3 dedicated full-time QC inspectors and an industrial conveyor needle detection line, we eliminate metal shards and production flaws before goods leave our factory.

The Conveyor Needle Detection Standard

Broken sewing needles pose severe product liability risks. Our facility utilizes a dedicated conveyor-type industrial needle detector (Needle Detectors: Yes). Every single completed garment passes through the electromagnetic coil sensor.

Dedicated inspectors continuously patrol the 12-sewer line, checking seam tension, collar rib symmetry, and hem straightness.

100% Finished Garment Audit

Every piece is measured across 8 critical points (chest width, body length, sleeve length, neck opening) to confirm ≤ 1cm tolerance.
