Aluminium System Windows Casement

Casement windows are a classic and reliable choice. They offer excellent ventilation and sealing. Our Aluminium System Windows Casement combines this style with system window technology. We use 6063-T5 aluminium profiles. The wall thickness is 1.6mm to 2.0mm. The frame width is 70mm to 120mm. We include PA66 thermal break strips and 5mm+12A+5mm insulated glass. We also offer LOW-E and triple glass options. The window can open inward or outward. The hardware is high-precision friction hinges. We also include anti-drop parts and opening restrictors. Our product is built for lasting performance.

We apply strict quality control to our Aluminium System Windows Casement. The cutting precision is within ±0.5mm. The corners are joined with special cleats and glue. This ensures strong and airtight corners. The overlap between the sash and frame is calculated precisely. This ensures the EPDM seal compresses perfectly when closed. This gives excellent air and water tightness. We launched our "Delangxuan System Windows" brand in 2023. Our casement system windows were the first to be upgraded. In 2025, we became a large-scale industrial enterprise. The monthly output of these windows is growing steadily. They are now used in many projects at home and abroad.
