Q690E plates were successfully developed in 2007 then set as   substitution of imports and applied in an 8000-ton floating crane project.   S690QL has been massively exported to Europe ,south Africa and other   countries since 2008. Q890 and Q960 have been successfully applied in over   70- ton capacity engineering lifting cranes and concrete-pump trucks in China   since 2010. S890QL and S960QL have been exported to Europe, Australia and   other countries since 2012. Q1100 has been successfully applied in the key components   of lifting cranes, like lifting arm. The new product of ultra-high strength   structural steel plate Q1300 passed the New Product Assessment in 2017 and   its technical level has achieved the international advanced level.
