Aluminum Alloy Window Series

Dongcheng's aluminum alloy window series is engineered for demanding residential, commercial, and high-rise applications. Built on precision-extruded, high-strength aluminum profiles, each window frame undergoes dual-layer surface treatment — anodized for long-term corrosion resistance and electrostatically coated for UV stability and color retention. A comprehensive glazing range is available, including double-layer insulating, tempered, and laminated glass configurations, ensuring consistent performance in thermal insulation, acoustic control, and weatherproof sealing.

The series covers a full spectrum of opening styles — sliding, casement, electric lift, folding, and suspended — allowing precise matching of ventilation requirements, spatial constraints, and aesthetic goals for any project. Every window is assembled with multi-layer EPDM sealing strips and heavy-duty, corrosion-resistant hardware, delivering reliable, low-maintenance performance across decades of daily use.

Whether serving compact urban apartments, open-plan commercial facades, or specialty architectural installations, the Dongcheng window series offers the structural integrity, customization depth, and finishing quality that modern building envelopes demand.
