Inspection Process
Our Process
6-Stage Quality Control
From incoming raw material to final shipment, every frame passes through six rigorous inspection stages.
Incoming Material Inspection
Every batch of raw aluminum is tested for alloy composition, hardness, and surface quality before entering the production line.
In-Process Inspection
Dimensional checks at every stage of extrusion, cutting, and machining. Automated vision systems detect surface defects in real time.
Mechanical Testing
Tensile strength, yield strength, and elongation tests ensure every frame meets or exceeds structural requirements.
Surface Quality Analysis
Anodization thickness, coating adhesion, and salt spray resistance testing guarantee long-term corrosion protection.
Final Inspection & Packaging
100% visual inspection and dimensional verification before protective packaging and shipment preparation.
Documentation & Traceability
Every frame is traceable from raw material to delivery with complete test certificates and quality documentation.
