DIRECT FACTORY. 15+ YEARS OF MANUFACTURING EXPERIENCE
Manufactured by FUJIAN DERYONG WINDOWS & DOORS CO., LTD. We fabricate high-performance exterior and interior aluminum door systems designed for villas, residential complexes, and modern commercial developments. Supported by a 60+ production team, in-house quality control, and flexible OEM/ODM capabilities for overseas distributors, builders, and importers.
From space-expanding folding patio doors to multi-track sliding and heavy-duty entrance systems,
our doors are built with robust extrusions, precision hardware, and multi-point sealing.
We collaborate directly with architectural drawings, window/door schedules, and project specifications:
FACTORY DIRECT QUALITY
Every aluminum door unit undergoes in-house quality inspection: profile mitering accuracy, corner crimping strength, multi-point hardware alignment, weatherstrip adhesion, and smooth sliding/folding operation before packaging.
Ocean Freight Security: Packed in heavy-duty export protective film, corner edge guards, and solid fumigated wooden crates or steel A-frames to guarantee intact arrival at overseas job sites and warehouses.
