Quality Control

**Rigorous Quality Control · Precision Craftsmanship for Timeless Elegance**  
Every bronze lighting fixture embodies our commitment to artistry and excellence. We engineer home decor with industrial-grade standards, ensuring end-to-end quality control that surpasses industry benchmarks.

**▌ Material Traceability**  
- T2-grade electrolytic copper certified by international standards, validated through SGS heavy metal emission tests  
- Fire-retardant cables (UL Certified) and high-transparency glass components  
- Batch-specific material certificates traceable to original mining sources  

**▌ Production Oversight**  
12 precision manufacturing stages with 4 critical inspection checkpoints:  
① Casting Molding: 3D scanning aligned with design blueprints (tolerance <0.5mm)  
② Surface Treatment: 72-hour salt spray test for oxidation-resistant coatings  
③ Electrical Safety: 100% full-circuit aging test + IP44 waterproof certification  
④ Assembly Verification: 360° light effect simulation eliminating color temperature deviation  

**▌ Final Inspection**  
- Full compliance with CE/FCC certifications and EU RoHS environmental directives  
- ISTA 3A standard transportation vibration simulation  
- 100% manual visual inspection with zero-tolerance defect policy  

**▌ Quality Assurance**  
Our dedicated QC team conducts regular on-site factory audits. Each lighting unit carries an independent quality inspection number for production record verification via official website.  

Let every beam filtering through bronze textures become an heirloom of guaranteed excellence.
