25、-2001钢结构用高频焊接薄壁H型钢中规定了45个型号的高频焊接H型钢。产品高度100-400mm,宽度50-200mmo这是根标准起草单位，当时国内唯一生产厂上海大通钢结构有限公司的实际情况制定的，现已满足不了钢结构市场要求。为此，根据我公司装备水平，决定产品规格有所突破，H型钢最大高度由400mm增加到500mm,H型钢翼缘宽度由200mm增加到250mm，产品型号由45个增加到66个，可缓解市场的需求。3、H型钢长度精度大幅度提高由于上海大通钢结构有限公司的高频焊接H型钢生产线，是91年从美国购进的色玛图尔公司制造的二手产品，剪切精度低。致使H型钢长度偏差大，根据当时实际水平JG/T13
