1、热轧H型钢尺寸规格(摘自GB/T112631998)H高度；B宽度；t1腹板厚度；t2翼缘厚度；r工艺圆角热轧H型钢理论重量计算公式：热轧H型钢理论重量=*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）热轧H型钢是一种截面面积分配更加优化、强重比更加合理的经济断面高效型材，因热轧H型钢规格断面与英文字母“H”相同而得名。热轧H型钢具有抗弯能力强、施工简单、节约成本和结构重量轻等优点，已被广泛应。热轧H型钢规格分为宽翼缘热轧H型钢规格（HW）、窄翼缘热轧H型钢规格（HN）和热轧H型钢桩规格
2、（HP）三类。热轧H型钢规格表示方法为：高度H宽度B腹板厚度t1翼板厚度t2，如H型钢Q235、SS400200200812表示为高200mm宽200mm腹板厚度8mm，翼板厚度12mm的宽翼缘H型钢尺寸规格，其牌号为Q235或SS400。热轧H型钢是一种新型经济建筑用钢。H型钢尺寸规格截面形状经济合理，力学性能好，轧制时截面上各点延伸较均匀、内应力小，与普通工字钢比较，具有截面模数大、重量轻、节省金属的优点，可使建筑结构减轻30-40%；又因其腿内外侧平行，腿端是直角，拼装组合成构件，可节约焊接、铆接工作量达25%。常用于要求承截能力大，截面稳定性好的大型建筑（如厂房、高层建筑等），以及桥梁
3、、船舶、起重运输机械、设备基础、支架、基础桩等。热轧H型钢主要用于用于工业厂房、民用建筑、市政工程、石油平台、桥梁、平板车大梁、电气化铁路的电力支架、铁路沿线的钢结构桥梁等轻型、超轻型H型钢非常适用于集装箱、移动房屋、各类车库、箱式火车、电气支架、各类场馆、小别墅制造业。整理为word格式整理为word格式(表一)类别型号(高度宽度)截面尺寸/mm截面面积/cm2理论重量/kgm-1截面特性参数HBt1t2r惯性矩/cm4惯性半径/cm截面模数/cm3IXIYiXiYWXWYHW宽翼缘100100100100681021.9017.23831344.182.4776.526.712512512
