Aluminium Sliding Window Sash

Our Aluminium Sliding Window Sash is our best-selling product. We have produced this item for over 15 years. Our factory started in 2010. We have deep experience with this design. In 2025, our monthly capacity for this window is 10,000 square meters. This number can reach 15,000 square meters at full capacity. This product is a top choice for contractors. They trust our product because we use only 6063-T5 virgin aluminium. We never use recycled material. This ensures the profiles are uniform. They resist corrosion well and do not bend easily. Pure material means a longer product life outdoors. We offer a 10-year warranty on the main structure. This shows our confidence.

In 2023, we created our own sub-brand, "Delangxuan System Windows". We use its strict quality standards for our Aluminium Sliding Window Sash. We do all work in our own 4,000-square-meter factory. We never outsource production. Every process is controlled. We cut, assemble, and inspect every unit here. We check each product fully before shipment. We verify its look, size, and function. This stops any bad units from leaving our factory. We use profiles with 1.4mm or 1.8mm thickness. The frame width is 60mm or 80mm. Glass options include 5mm single tempered glass or 5mm+12A+5mm insulated glass. We offer electrostatic powder coating or fluorocarbon coating. Colors are customizable. Our key advantage is this: we give you system-window quality at a factory price.

Here are the standard specifications for our Aluminium Sliding Window Sash.

Our Aluminium Sliding Window Sash is packed for international shipping. We use inner foam wrapping and corner protection. The outer layer uses strong wooden boxes or steel frames. We can change this if you have special needs. We offer EXW and FOB terms. We ask for a 50% deposit upfront. We collect the remaining 50% before shipping. Large orders can get a discount. More frequent re-orders also give you a better price.
