ISO Certification

　　After more than one month's efforts, we have finally obtained the ISO quality management system certification. In obtaining the certification process, we re-organized the entire production process and our quality control system. From the purchase of steel ingots to the delivery of finished products, from the chemical composition inspection to ultrosonic flaw detection, we strictly control every step in accordance with the trade standards, customers' requirements and ISO management system. In future, we will always strictly control the quality and provide customers with qualified products and services.
