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%.
