Our China factory is ISO 9001 certified. We test each batch for:
Breaking strength (550 lb minimum)
Sheath slippage (less than 1 inch under 200 lb load)
Diameter consistency (laser gauge)
Colorfastness (AATCC standard)
Suggested images: ISO certificate / tensile tester / braiding machine line / QC checking diameter

As a direct manufacturer in China, we provide laboratory test reports upon request. We’ve supplied to military surplus stores, outdoor retailers, and government agencies worldwide.
