Quality Control and Third-Party Testing at PPD Doors

At Yongkang Phipulo Smart Home Co., Ltd. (PPD), we understand that consistent quality is the backbone of any reliable door manufacturing operation. While our official website does not currently list specific certifications such as ISO 9001, we operate a 50,000 square meter factory with rigorous internal quality assurance processes designed to meet the expectations of clients in over 106 countries.

Our production line for steel doors, wooden doors, and smart locks follows a multi-stage inspection protocol—from incoming raw material verification to in-process dimensional checks and final functional testing. Every batch of doors is subject to visual, structural, and mechanical tests to ensure uniform thickness, surface finish, and hardware alignment. For fire-rated steel doors, we also coordinate with third-party laboratories to verify thermal insulation and fire-resistance performance, ensuring compliance with international safety benchmarks.

We encourage customers to request our latest certification documents or arrange a factory audit. Our team can provide detailed test reports and quality records upon request.

We are located at 22th East Floor, Jinbi Building, Dongcheng Street Trade Center, Yongkang City, Jinhua, Zhejiang, China.
