D&D HARDWARE has steadily developed its business around commercial and fire door applications.
Initially based on the manufacturing and export of architectural door hardware, the company gradually accumulated understanding of
applications such as wooden doors, steel doors, fire doors, emergency exit doors, and commercial glass doors by serving door manufacturers, brand owners, and distributors in various countries.
As customers' requirements for product durability, fire resistance, and market access have continuously increased, D&D has continuously improved its product development, mold manufacturing, raw material inspection, performance testing, production process control, and finished product inspection systems, and has promoted related products to obtain international standard certifications such as UL, cUL, ANSI/BHMA, and CE/EN.
