During the production of smart led street light-angle tower, Foshan Nanhai Guanheng Steel Structure Co.,Ltd divides the quality control process into four inspection stages. 1. We check all incoming raw materials before usage. 2. We perform inspections during the manufacturing process and all manufacturing data are recorded for future reference. 3. We check the finished product according to the quality standards. 4. Our QC team will randomly check in the warehouse before shipment. . To expand our GH brand, we conduct a systematic examination. We analyze what product categories are suitable for brand expansion and we make sure these products can offer specific solutions for customers' needs. We also research different cultural norms in the countries we plan to expand into because we learn that foreign customers' needs are probably different from those of domestic.. Our dedicated and knowledgeable staff have extensive experience and expertise. To meet the quality standards and provide high quality services at GH Steel Structure, our employees participate in international cooperation, internal refresher courses, and a wide variety of external courses in the areas of technology and communication skills..
