Aluminum Alloy Door

Aluminum alloy doors are crafted from high-strength aluminum profiles through precision machining and advanced surface treatments, combining aesthetic appeal with practical performance. Lightweight yet exceptionally durable, they offer outstanding resistance to corrosion and deformation, significantly extending service life. With infill options such as insulated glass or honeycomb panels, these doors deliver good soundproofing, thermal insulation, and waterproofing—making them suitable for a wide range of climate conditions. The surface can be customized with various textures, including wood grain and metallic finishes, offering versatile design compatibility for both residential and commercial settings — such as entrance doors, balcony dividers, and retail interiors. Flexible opening styles, including sliding and swing mechanisms, can be seamlessly integrated with smart lock systems to enhance safety and adapt to different usage scenarios. These doors represent a modern, intelligent, and stylish solution for contemporary architectural applications.

  • The soundproof aluminum alloy folding door adopts aviation-grade aluminum alloy profiles, with hidden damping hinges and precision slide rails, to achieve smooth folding and opening, combining spatial flexibility with modern aesthetics. The profile is treated with nano-ceramic coating and fluorocarbon spraying, which is wear-resistant, corrosion-resistant, and has a high-quality texture; the door leaf can be made of low-E hollow glass, heat-insulating and UV-resistant, or lightweight and high-strength panels such as honeycomb aluminum panels. Magnetic sealing strips and embedded drainage grooves enhance air and water tightness, and silent pulleys reduce shock and buffer, making opening and closing quiet. It is suitable for scenes such as balcony-living room connections and open kitchens, especially for small apartments, helping to flexibly switch spaces, and is both practical and beautiful.

  • High-strength aluminum alloy sliding doors are built with aviation-grade extruded aluminum frames and glide smoothly along upper and lower tracks—offering a sleek appearance and efficient use of space. The profiles are treated with fluorocarbon coating and nano-ceramic layers, delivering exceptional corrosion and scratch resistance along with long-lasting color stability. The door panels can be fitted with low-E insulated glass, effectively blocking UV and infrared radiation while enhancing thermal insulation. Premium configurations feature magnetic sealing strips and integrated drainage systems, significantly improving air and water tightness and preventing leakage. Silent sliding is achieved through damping track technology, combined with shock-absorbing rubber pads and cushioned springs. Ideal for both residential and commercial spaces, these doors strike a balance between aesthetics and functionality.

  • Lightweight aluminum alloy swing doors feature high-strength aluminum frames and open elegantly inward or outward via side-mounted hinges—striking a balance between aesthetics, functionality, and compatibility with modern architectural styles. The aluminum profiles offer outstanding resistance to impact and abrasion, while advanced surface treatments such as electrophoresis and powder coating provide a corrosion-resistant, mirror-like finish in a variety of customizable colors. The door leaf can be configured with flexible material options. Argon-filled insulated glass, combined with thermal break aluminum and PA66 nylon insulation strips, significantly enhances heat and cold insulation performance. Multi-layer glass paired with sealing strips ensures effective sound reduction, while optional honeycomb aluminum panels deliver lightweight strength, fire resistance, and durability for premium applications. Swing doors are available in single-leaf or double-leaf configurations. The single-leaf design is ideal for compact spaces, while the double-leaf version offers a broader opening area—suitable for villas, storefronts, and spacious interiors. Merging contemporary aesthetics with advanced performance, this door system fits seamlessly into modern architectural needs.
