等边角钢知识.doc

等边角钢知识 角钢俗称角铁、是两边互相垂直成角形的长条钢材。有等边角钢和不等边角钢之分。等边角钢的 两个边宽相等。其规格以边宽边宽边厚的毫米数表示。如“30303”，即表示边宽为 30毫米、边厚为3毫米的等边角钢。也可用型号表示，型号是边宽的厘米数，如3#。型号不表示同一型号中不同边厚的尺寸，因而在合同等单据上将角钢的边宽、边厚尺寸填写齐全，避免单独用型号表示。热轧等边角钢的规格为2#-20#。角钢可按结构的不同需要组成各种不同的受力构件，也可作构件之间的连接件。广泛地用于各种建筑结构和工程结构，如房梁、桥梁、输电塔、起重运输机械、船舶、工业炉、反应塔、容器架以及仓库货架等。角钢属建造用碳素结构钢，是简单断面的型钢钢材，主要用于金属构件及厂房的框架等。在使用中要求有较好的可焊性、塑性变形性能及一定的机械强度。生产角钢的原料钢坯为低碳方钢坯，成品角钢为热轧成形、正火或热轧状态交货。热轧等边角钢每米重量表：角钢号数尺寸（毫米）截面面积（cm2)理论重量（kg/m)表面积(m2/m)Bbdr22033.51.1320.8890.07841.4591.1450.0772.52533.51.4321.1240.09841.8591.4590.09733034.51.7491.3730.11742.2761.7860.1173.63634.52.1091.6560.14142.7562.1630.14153.3822.6540.141440352.3591.8520.15743.0862.4220.15753.7912.9760.1564.545352.6592.0880.17743.4862.7360.17754.2923.3690.17665.0763.9850.17655035.52.9712.3320.19743.8973.0590.19754.8033.770.19665.6884.4650.1965.656363.3432.6240.22144.393.4460.2255.4154.2510.2288.3676.5680.2196.363474.9783.9070.24856.1434.8220.24867.2885.7210.24789.5157.4690.2471011.6579.1510.246角钢号数尺寸（毫米）截面面积（cm2)理论重量（kg/m)表面积(m2/m)Bbdr770485.574.3720.27556.8755.3970.27568.166.4060.27579.4247.3980.275810.6678.3730.2747.575597.3675.8180.29568.7976.9050.294710.167.9760.294811.5039.030.2941014.12611.0890.293880597.9126.2110.31569.3977.3760.314710.868.5250.314812.3039.6580.3141015.12611.8740.31399061010.6378.350.354712.3019.6560.354813.94410.9460.3531017.16713.4760.3531220.30615.940.3521010061211.9329.3660.393713.79610.830.393815.63812.2760.3931019.26115.120.3921222.817.8980.3911426.25620.6110.3911629.62723.2570.391111071215.19611.9280.433817.23813.5320.4331021.26116.690.4321225.219.7820.4311429.05622.8090.43112.512581411.93215.5040.4921013.79619.1330.4911215.63822.6960.4911419.26126.1930.19角钢号数尺寸（毫米）截面面积（cm2)理论重量（kg/m)表面积(m2/m)Bbd37321.4880.5511232.51225.5220.5511437.56729.490.551642.53933.3930.54916160101631.50224.7290.631237.44129.3910.631443.29633.9870.6291649.06738.5180.62918180121642.24133.1590.711448.89633.3830.7091655.46743.5420.7091861.95548.6340.7
