Customer Feedback
| Issues of concern | Lange solutions |
|---|---|
| Sagging After Long-term Use: Excessive leaf weight causes track deformation over time. | Reinforced Guide Rails: 3.0mm thick aviation-grade aluminum tracks paired with precision steel bearings guarantee zero sagging for 10 years. |
| Air & Water Leakage: Numerous folding joints often lead to poor sealing and moisture penetration. | Multi-layer EPDM Sealing: Double sealing strips at every joint ensure premium airtightness and Class 4+ watertightness. |
| Logistics Damage: Large-scale glass folding doors are highly fragile during international shipping. | Steel-Reinforced Crates: Custom-engineered steel-wood composite packaging, maintaining a damage rate of less than 0.1%. |
