Chemical composition analysis
ISO-driven system
ISO 9001 quality management paired with ISO 14001 environmental controls across our factories.
Evidence on file
Batch-level photos, certificates, and lab reports stored for retailer and audit requests.
U.S. retail readiness
Proof-load, coating, and dimensional checks aligned with private label and distribution programs.
Quality Management
Systemized controls from supplier to shipment
Our QA team maintains calibrated gauges, layered audits, and traceable records that connect directly to the raw-material and finished-product inspections below.
Calibration & audits
Gauge R&R, gage blocks, and documented calibration cycles across torque tools, CMM, and load equipment.
Training & sign-off
Operator training matrices with sign-offs for welding, coating, packing, and inspection checkpoints.
Labs & equipment
- Horizontal proof-load frames up to 300 kN with digital recording
- CMM, micrometers, and custom gauges for thread, lay length, and bend radii
- Coating thickness, hardness testers, and salt-spray chambers with logged hours
Incoming Materials
Inspection Equipment And Measures For Raw Material
Every heat and batch is verified before release to production. We document chemistry, structure, and defects so downstream forming, welding, and coating stay stable.
Material metallographic structure analysis
Hardness analysis
Detective test
Finished Goods
Inspection Equipment And Measures For Finished Products
Finished assemblies are validated against the control plan with load, coating, and dimensional checks—plus usability confirmation before shipment.
Breaking load test
Coating inspection
Weight, length, size, surface quality
Salt spray test
Packaging reliability & quality
Automatic cutting/grinding
Evidence Package
Ready for audits, retailers, and industrial programs
We maintain organized QA packets for every program—making it easy to respond to supplier scorecards, private label compliance requests, and site audits.
Traceability
Date-coded batches with matching lab data and process photos retained for 3+ years.
Documentation
COCs, PPAP-style packets, MSDS, and test reports available by SKU or PO.
Response
Nonconformance protocols with 8D reporting and corrective action tracking.
