H型钢理论重量表如下：
热轧H型钢理论重量计算公式：热轧H型钢理论重量
=<hd+2r(b-d)+0.8584(r2-r12)>*L*7.85*1/1000
其中 h----高度（MM），b----脚宽（MM），d----腰厚（MM），r----内面圆角半径（MM）r1----边端圆角半径（MM），L-----长度（M）
扩展资料
H型钢的翼缘内外侧平行或接近于平行，翼缘端部呈直角，因此而得名平行翼缘工字钢。H型钢的腹板厚度比腹板同样高的普通工字钢小，翼缘宽度比腹板同样高的普通工字钢大，因此又得名宽缘工字钢。由形状所决定，H型钢的截面模数、惯性矩及相应的强度均明显优于同样单重的普通工字钢。
用在不同要求的金属结构中，不论是承受弯曲力矩、压力负荷、偏心负荷都显示出它的优越性能，可较普通工字钢大大提高承载能力，节约金属10%～40%。H型钢的翼缘宽、腹板薄、规格多、使用灵活，用于各种桁架结构中可节约金属15%～20%。
由于其翼缘内外侧平行，缘端呈直角，便于拼装组合成各种构件，从而可节约焊接、铆接工作量25%左右，能大大加快工程的建设速度，缩短工期。

首先，为什么要计算？直接查表就行
如果非要算，那就把H钢分解为三块钢板，分别长×宽×厚×7.8，再加起来就行了
H型钢没有300*600这个规格.只有600*200*11*17每米105公斤.H型钢没有公式有一个重量表
