Energy Saving Aluminium Doors

Door openings are major areas for heat loss. This makes our Energy Saving Aluminium Doors very important. They play a key role in any energy-saving plan. We use 6063-T5 aluminium profiles for these doors. The wall thickness is 1.8mm to 2.2mm. The frame width is 80mm to 120mm. This is thicker than window profiles. This gives the doors more stability. The door leaf uses 5mm+12A+5mm insulated glass as standard. We can also add LOW-E coatings or triple glass. We use EPDM automotive-grade seals between the frame and leaf. When closed, the door creates a complete seal. This stops heat from moving between inside and outside.

We officially established our company in 2016. Aluminium door products have always been a core part of our business. In 2023, we launched our "Delangxuan System Windows" brand. This raised the quality bar for our Energy Saving Aluminium Doors. Our factory is located in Huangshan, Anhui. It covers over 4,000 square meters. We have complete production workshops and standard assembly lines. We control all processes internally. This includes cutting, forming, machining, and final assembly. Overseas buyers value this control. We promise that every step for our Energy Saving Aluminium Doors is done in our own factory. This keeps quality consistent and reliable. In 2025, we were certified as a large-scale industrial enterprise. This official recognition shows our strength in quality and management.

Our Energy Saving Aluminium Doors are now sold in many provinces. We are also exporting them to overseas markets. The product is suitable for many building types. These doors work well for homes, villas, offices, and hotels. They are a good choice for energy-conscious projects. Please refer to the table for detailed specifications.
