GET PRICE “Q” stands for the first letter of “flexural” Chinese pinyin for wind steel yield, “345” stands for the lower limit of yield strength in N / mm², “FT” stands for the first letter of Chinese wind tower pinyin, and “D” stands for quality grade symbol. When it is required that the steel plate has a thickness direction property, the symbol “z15” (z25, 235) of the thickness discovery (z direction) performance level is added to the above predetermined grades.
