Fabricator catenarum ferrearum rotundarum per triginta annos, officina nostra per tempus evolutionis industriae catenarum Sinarum, maximi momenti, perseveravit et eam inservivit, quae fodinis (praesertim carbonariis), onera gravia sublevanda, et necessitates translationis industrialis catenarum ferrearum rotundarum altae firmitatis curavit. Non solum princeps fabricator catenarum ferrearum rotundarum in Sinis sumus (cum copia annua plus quam decem milia tonnarum), sed etiam continuae creationi et innovationi adhaeremus.
