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. |
