Hangzhou Yongjin Doors Co., Ltd

Hangzhou Yongjin Doors Co., Ltd. has been in business since 2013, which shows a stable presence in the door and window manufacturing space. Being based in Hangzhou, a major industrial hub in eastern China, gives them access to strong supply chains for aluminum profiles and hardware. Their core products — doors, windows, gates, shutters, and aluminum profile — cover a full range of building envelope solutions, making them a one-stop supplier for construction projects. However, none of their key verification details — documents, work email, phone number, or account email — have been confirmed. This lack of verification raises a red flag for buyers who need to ensure legitimacy before placing large orders. Without verified contact or business documents, it's hard to trust their ability to deliver on time or meet technical specifications. Buyers should request additional proof before engaging in serious business.
