Custom Aluminum Window & Door Solutions

Engineered by FUJIAN DERYONG WINDOWS & DOORS CO., LTD. We bridge architectural design and precision manufacturing. Supported by 15+ years of industry experience and around 60 dedicated manufacturing specialists, we provide end-to-end custom fabrication, OEM/ODM production, and specialized project packages for overseas distributors, dealers, builders, and project contractors.

Custom Sizes & Opening Configurations

Every architectural project possesses distinct rough opening dimensions and structural wind-load requirements. At Deryong, we do not restrict buyers to fixed off-the-shelf catalog dimensions. We engineer each door and window system to your exact architectural specifications.

Oversized & Non-Standard Rough Openings

Custom structural heights and spans for grand entrance doorways, floor-to-ceiling panoramic glass panels, and expansive multi-lite window walls.
Multi-Leaf Flexible Opening Layouts

Bifold doors from 3 to 8 folding panels (left, right, or split folding); multi-track sliding systems (2, 3, or 4 tracks) including 90-degree postless corner sliding and concealed wall pocket configurations.
Geometric Shapes & Modular Combinations

Fixed picture windows coupled seamlessly with operable casement or awning sashes; arched, trapezoidal, or clerestory transom combinations designed to architectural drawings.
