Ordinary Coated Curtains vs Buyancheng Class A
Curtains endure sunlight year-round. Choosing eco-safe fabrics protects your family long-term.
Ordinary Coated Curtains
Inferior Coating- Chemical coating releases formaldehyde and VOCs under solar radiation.
- Coating becomes sticky, cracks and powders within 1-2 years.
- Poor durability; coating easily cracks or peels off upon dampness or cleaning.
- No memory shaping; edges flare and folds hang unevenly.
- Marked up by middlemen with zero quality assurance.
Buyancheng Class A Custom Curtains
Class A Certified- Pure triple-layer physical black silk weave, 0 coating, zero formaldehyde.
- Physical blackout lasts 10+ years without fading or hazardous odor.
- Professional dry cleaning recommended; retains pristine soft drape and fabric elegance.
- 160°C steam memory shaping locks permanent wave folds without ironing.
- Factory-direct pricing backed by 1-year warranty and lifetime care.
4-Step Final Factory Quality Verification

2. Lightbox Inspection
Inspected on high-lux light tables for blackout consistency.
3. Hanging Drape Test
Hanged on test racks to verify vertical alignment and ripple symmetry.
4. Dust-Proof Packaging
Steam cleaned and packaged in protective moisture-proof bags.
