To strike iron, one must first be strong oneself. The healthy and steady development of a company requires genuine technology and services. The prerequisite is to have the corresponding company qualifications to get the opportunity to undertake projects and showcase its strength and technology. Therefore, with the active efforts of all employees of Yanyi Construction Group Co., Ltd., recently, the aluminum profiles independently developed and produced by our company have officially obtained the third-party inspection report from the National Quality Inspection and Testing Center for Building Curtain Walls and Doors and Windows. We strive to develop into a new industry standard, laying a solid foundation for the future development of the company.

The certification of the inspection report certificate, that is, quality certification, is carried out by testing various indicators such as chemical composition, mechanical properties, dimensional deviation, film thickness, appearance quality, characteristic value of longitudinal shear resistance at room temperature, and characteristic value of transverse tensile resistance at room temperature. It is a means of mandatory assessment for inspection institutions that issue notarized data for society, and it can also be said to be the inspection and recognition of Yanyi's aluminum materials. The data that have passed the inspection and certification of the report have legal effect and are used in aspects such as product quality evaluation and achievement appraisal.

The acquisition of the quality inspection report certificate of Yanyi Group's aluminum profiles marks that our company's management has taken an important step forward in terms of scientific, refined, and standardized management. In future development, Yanyi Group will continue to work hard, constantly pursue excellence, and repay the support and love of our vast number of customers with more exquisite technology and higher-quality services!
