Located in Taizhong in Taiwan, the integrated BMY of Dragon Steel Corporation will be constructed by China Steel Structure Co., Ltd., modifying the original open yard to enclosed one as required by environmental protection. The stockyard is designed with storage capacity of 2Mt/a and planned to be rebuilt online in different phases, in intent of affecting as little as possible the present production; nonetheless, it would exert a great challenge for conducting such online modification. Thanks to CISDI’s rich experience and satisfactory references in enclosed BMY engineering, China Steel concluded the full-process consulting agreement to CISDI from design to construction of the project under the framework of mutual strategic partnership.
