Guangdong Dejiyoupin Doors and Windows Co., Ltd., globally recognized under our flagship brand DERCHI, is based in Foshan, Guangdong Province—the epicentre of advanced metal fabrication and fenestration engineering. Ranked firmly within the Top 10 premium door and window manufacturers in China, our team delivers more than 25 years of relentless research, precision tooling, and global project delivery.
Unlike conventional interior fire doors that rely on unsealed particleboard, every UL fire-rated entry door manufactured at our facility is designed specifically for extreme external exposure. Our structural team combines UL 10C positive pressure fire standards with cyclonic wind-load resistance, waterproof triple-rebate thresholds, and high-security multi-point locking hardware. We empower international real estate developers, commercial general contractors, and facade designers by transforming complex building codes into certified, factory-direct architectural realities.
