So far we have achieved many milestones. At present the stacker-reclaimers with the largest capacity in the cement industry are all designed and built by SDA (such as Huaxin Cement’s 2*5kt/D production lines, CUCC Lunan’s 2*5kt/D production lines, CUCC Qingzhou’s 2*6kt/D production lines and Huizhou Guangda’s 2*5kt/D production lines). Among our key customers there are numerous giant cement groups, including Zhonglian Cement, Zhejiang Leomax Group, Jinan Sunnsy Group, Wuhan Huaxin Group, Jidong Group, Taihang Group, Qinling Cement Group, Changchun Yatai Group, Henan Mengdian Group, Tianrui Group, etc. Some of them are state owned, some are from the private sector, and some have even gone listed. From 2001 to 2020, we signed nearly 500 contracts for supply of production lines. Meanwhile we have established long-term strategic partnership with some large-sized companies. Our products are now exported to 58 countries including Europe, Pakistan, Brazil, Thailand and Vietnam.
