| Quality control is implemented throughout every production process. |
| Raw materials are inspected before production. Chain dimensions, weld integrity, heat treatment performance, proof load, and breaking force are tested during manufacturing. Finished products are inspected again before packaging and shipment. |
| Our QC team performs onsite inspections and maintains production traceability records for every batch. Test certificates and inspection reports can also be provided upon request. |
