In early August, during the height of summer and accompanied by the chirping of cicadas in the branches, Qunsheng Group and Qunsheng Doors & Windows welcomed an audit team from the Certification Center of the Third Research Institute of the Ministry of Public Security to conduct the annual supervisory audit (GA certification) on the company’s entire range of anti-theft doors.

GA certification

The Certification Center of the Third Research Institute of the Ministry of Public Security is a certification body approved by the State Administration for Market Regulation and the Ministry of Public Security, authorized to carry out product conformity assessment. The certification mark for public security products features the letters "GA," which not only represent the initial letters of "Gong'an" (public security) in pinyin but also serve as the code for the public security industry standards upon which the certification is based. The shield-shaped outline of the mark symbolizes that the certification will provide solid and robust quality assurance for the development of the public security industry. Over the years, it has played a significant role in ensuring the consistency of mass-produced products and enhancing the overall quality of products.

GA Certification Meeting

At the first meeting, Tan Guozhi, Deputy General Manager and Management Representative of Qunsheng Doors and Windows, along with heads of relevant departments, extended a warm welcome to the audit team.

The company that has obtained the “GA” certification has attached great importance to this process. Heads of various departments have already prepared in advance the detailed documentation required for the certification audit. The audit team reviewed the company’s workshop production lines and manufacturing environment in accordance with relevant national product certification regulations, laws, and standard requirements. The review covered a range of elements, including documents related to workshop operations, supplier management, production process control, process inspection records, and finished-product inspection records.

After a series of rigorous reviews, the certification body unanimously concluded that the company’s management and operational system is well-established and, at the final meeting, announced that Qunsheng Group and Qunsheng Doors & Windows had successfully passed this “GA Certification.”

With the development of the anti-theft door industry, “GA certification” has become an indispensable credential for brand-name enterprises. It provides consumers with a clear value commitment and inherently carries the cost of social oversight. When choosing among similar products, consumers are more inclined to purchase branded items that boast a full complement of certifications, as these products enjoy an absolute advantage in terms of quality assurance and social recognition.

Qunsheng Doors and Windows is one of the earliest companies in China’s anti-theft door industry to obtain “GA Certification.” As a well-known brand in the industry, for decades Qunsheng has been committed to providing consumers with high-quality services while leveraging its strong product capabilities, premium brand positioning, and standardized production processes as its core competitive advantages. This has further promoted the establishment of unified production standards within the doors and windows industry, enabling Qunsheng to fully capitalize on its strengths and drive self-discipline, innovation, and development in China’s doors and windows sector.

On the road ahead, Qunsheng Doors and Windows will continue to drive its high-quality development by maintaining a rigorous R&D approach, building on a solid professional foundation, and leveraging its extensive industry experience—while also achieving mutual success with consumers.
