In 2010, Harzone was awarded purchase contract by Shuohuang Railway Development Co., Ltd. through bidding. Up until now, the six-four girder structure has been manufactured and passed appraisal. The six-four girder is more advanced than the six-five pier purchased by the Company, easier to assemble, so is able to replace eight-three pier and six-five pier. The tendering committee of the Company showed deep interest in new products of our Company. By now, the contract has been performed successfully.
