4、H型鋼的扎機是**軋機，與扎工字鋼的不同，H型鋼的翼緣都是等厚度的，有軋制截面，也有由3塊板焊接組成的組合截面。工字鋼都是軋制截面。 </p> <p> 5、工字鋼主要很多用于各種建筑、結(jié)構(gòu)、橋梁、車輛、支架、機械等，一般由于截面尺寸相對較高較窄，所以在建筑、鋼結(jié)構(gòu)中一般直接用于在其腹板品面內(nèi)受彎的構(gòu)件，應(yīng)用范圍有很大的局限。 </p> <p> 6、H型鋼主要很多用于工業(yè)與民用建筑鋼結(jié)構(gòu)中的梁、柱構(gòu)件，工業(yè)構(gòu)筑物的鋼結(jié)構(gòu)承重支架等。昆明工字鋼哪家好</p><p
