t型钢也叫丁字钢，因其横截面与英文字母“t”中文汉字“丁”相近而得名。t型钢因生产工艺的不同而分为多种叫法，如：热轧t型钢、剖分t型钢、冷拉t型钢、焊接t型钢。 t型钢q235b/q345b25*25*3 t型钢q235b/q345b25*25*4 t型钢q235b/q345b30*30*3 t型钢q235b/q345b30*30*4 t型钢q235b/q345b35*35*3 t型钢q235b/q345b35*35*4 t型钢q235b/q345b40*40*3 t型钢q235b/q345b40*40*4 t型钢q235b/q345b40*40*5 t型钢q235b/q345b40*40*6 t型钢q235b/q345b45*45*5 t型钢q235b/q345b45*45*4 t型钢q235b/q345b45*45*6 t型钢q235b/q34550*50*5 t型钢q235b/q34550*50*6 t型钢q235b/q34550*50*7 t型钢q235b/q345b60*60*6 t型钢q235b/q345b60*60*7 t型钢q235b/q345b60*60*8 t型钢q235b/q34550*50*5*7 t型钢q235b/q34550*100*6*8 t型钢q235b/q345b62.5*60*6*8 t型钢q235b/q345b62.5*125*6.5*9 t型钢q235b/q345b75*75*5*7 t型钢q235b/q345b74*100*6*9 t型钢q235b/q345b75*150*7*10)
