Custom Aluminum Alloy Door And Window Manufacturer

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 cont...

Dongcheng's aluminum alloy door series combines robust structural engineering with refined finishing to deliver door solutions for residential, commercial, and public-access environments. The frames are fabricated from quality aluminum alloy profiles, surface-treated for corrosion resistance and long-term color stability, and paired with a range of panel materials — tempered glass, ecological board, and frosted panels — to suit functional and aesthetic requirements across diverse settings.

Opening mechanisms span sliding, top-track, c...

Dongcheng's aluminum alloy sunroom series transforms outdoor courtyards, terraces, and garden spaces into fully functional, year-round living areas. Main frames are constructed from heavy-gauge aluminum profiles that have been treated for weather resistance, enabling the structure to withstand prolonged sun exposure, heavy rainfall, strong winds, and seasonal temperature extremes without warping or corroding.

A broad selection of roof forms — flat, arched, A-frame, pyramid, dome, and bespoke irregular geometries — allows each sunroom ...

Dongcheng's aluminum alloy skylight series is engineered to introduce natural light and controlled ventilation into building rooftops without compromising structural integrity or waterproofing performance. Frame profiles are lightweight, high-strength aluminum alloy, paired with anti-explosion, UV-resistant glazing and precision-engineered multi-layer sealing systems that reliably prevent water ingress under sustained rain and wind pressure.

The series spans manual, motorized, top-hung, flush-lift, horizontal-sliding, and custom-profi...

Dongcheng's aluminum alloy louver series delivers precision-engineered ventilation, shading, and privacy control for residential and commercial applications. Each louver blade is formed from one-piece extruded aluminum, eliminating joints that could trap dust or moisture, and the full assembly — blades, frame, adjustment hardware, and mounting brackets — is fabricated from corrosion-resistant aluminum alloy treated for long-term outdoor and high-humidity performance.

Fixed and operable blade configurations are available, with the oper...

Dongcheng's aluminum alloy railing series provides structural safety and refined visual character for balconies, terraces, staircases, and window perimeters across residential and commercial building types. Profile stock ranges from solid to hollow-section aluminum alloy, selected by application load requirement, with all components welded, assembled, and surface-coated to exacting standards for corrosion resistance and long-term finish stability.

Design options include minimalist vertical-bar configurations, decorative laser-cut patt...

Dongcheng's aluminum alloy curtain wall systems are designed for high-rise and landmark commercial buildings where facade performance, structural integrity, and architectural expression must all meet the highest standards. Primary frames are fabricated from high-performance aluminum alloy profiles — lightweight yet rigid enough to carry large-format cladding panels — and are available in both unitized and stick-built assembly methods to suit project scheduling and installation logistics.

Cladding options include tempered glass, alumin...

Dongcheng's aluminum single panels are manufactured from premium aluminum alloy sheet stock, processed through precision shearing, bending, punching, and surface coating to produce facade and interior cladding panels of consistent quality and dimensional accuracy. Panel thickness ranges are available to match structural and weight requirements for different applications, from lightweight interior ceiling systems to full-weight exterior facade cladding.

Surface treatment options include fluorocarbon spray coating, powder coating, wood-...
