1、-工字钢规格表及工字钢理论重量表工字钢也称钢梁，是截面为工字形的长条钢材。其规格以腰高( h)*腿宽(b)*腰厚(d)的毫数表示，如“工160*88*6，即表示腰高为160毫米，腿宽为88毫米，腰厚为6毫米的工字钢。工字钢的规格也可用型号表示，型号表示腰高的厘米数，如工16#。腰高一样的工字钢，如有几种不同的腿宽和腰厚，需在型号右边加a b c 予以区别，如32a# 32b# 32c#等。 工字钢分普通工字钢和轻型工字钢，热轧普通工字钢的规格为10-63#。经供需双方协议供给的热轧普通工字钢规格为12-55#。工字钢广泛用于各种建筑构造、桥梁、车辆、支架、机械等。品名型号明细规格理论重量工字钢
