Company Profile
A Leading Architectural Door Manufacturer for North American Standards
Guangdong Dejiyoupin Doors and Windows Co., Ltd. operates as an industry-leading manufacturer specializing in high-performance aluminum, cast aluminum, architectural glass, and stainless steel door systems.
Recognized for strict manufacturing standards and world-class product engineering, our facility combines automated fabrication with bespoke architectural craftsmanship. We deliver end-to-end entrance solutions for commercial developments, luxury residential villas, and custom architectural estates across the United States and Canada.
From custom rough-opening dimensions and imperial door schedules to severe climate engineering (thermal breaks, hurricane impact ratings, and AS 2047 / UL criteria), our technical department translates architectural visions into verified, jobsite-ready installations.
Our direct-to-factory model eliminates intermediaries, offering project managers, general contractors, and architects unparalleled quality assurance, transparent production scheduling, and dedicated technical support.
