Production Monitoring
On-site quality control at every stage — from raw materials to final shipment.
Our production monitoring service provides on-site factory inspections and quality control throughout your window & door manufacturing. We catch defects early, verify material specifications, and ensure every unit meets your requirements before it leaves the factory.
Inspection Stages
- Raw material verification (profile alloy, glass, hardware brands)
- In-process inspection (cutting accuracy, welding/seaming quality)
- Assembly inspection (corner joining, hardware fitting, seal application)
- Finished product inspection (dimensions, operation, appearance)
- Performance evidence review (air/water infiltration, operating force) — accredited-lab reports checked against the series you are buying, with in-process operating checks
- Packaging and loading supervision
- Pre-shipment audit following AQL sampling standards
