工字钢工字钢的规格尺寸及常识.图片标题工字钢所属词条工字钢钢质型材的一种，也称钢梁，是截面为工字形的长条钢材-由此得名“工字钢”。 工字钢 规格及型号 其规格以腰高( h)腿宽(b)腰厚(d)的毫数表示，如“工160886”，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。 标称规格 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#。腰高相同的工字钢，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。

19M；型号20-63，通常长度6-19 M定尺，倍尺长度：工字钢按定尺或倍尺长度交货时，应在合同中注明。定尺和倍尺长度小于等于8M，其允许偏差为+ 40 MM0长度大于8M，其允许偏差为+80MM 0长度大于8M时，每增加1 M，允许偏差增加5 MM，但是最大不得超过80MM非定尺和定尺的供应数量由供需双方协商确定重量工字钢按理论重量或实际重量交货工字钢计算理论重量时，钢的密度为7.85G/立方厘米工字钢截面面积的计算公式为：HD+2T（B-D）+0.815（R平方-R1平方）普工20a：截面高度H=200mm；截面宽度B=100mm；翼缘厚度tf=11.4mm；腹板厚度tw=7mm；截面面积A=3555mm2；惯性矩Ix=23690000mm4；惯性矩Iy=1579000mm4；截面模量Wx=236900mm3普工20b：截面高度H=200mm；截面宽度B=102mm；翼缘厚度tf=11.4mm；腹板厚度tw=9mm；截面面积A=3955mm2；惯性矩Ix=25020000mm4；惯性矩Iy=1690000mm4；截面模量Wx=250200mm3；截面模量Wy=33137mm3；轻工20：截面高度H=200mm；截面宽度B=100mm；翼缘厚度tf=8.4mm；腹板厚度tw=5.2mm；截面面积A=2680mm2；惯性矩Ix=18400000mm4；惯性矩Iy=1150000mm4；截面模量Wx=184000mm3轻工20a：截面高度H=200mm；截面宽度B=110mm；翼缘厚度tf=8.6mm；腹板厚度tw=5.2mm；截面面积A=2890mm2；惯性矩Ix=20300000mm4；惯性矩Iy=1550000mm4；截面模量Wx=203000mm3热轧等边角钢5#b=50mm,d=3mm,r=5.5mm,截面面积2.971cm2,理论重量2.332公斤/米，外表面积0.197米2/米b=50mm,d=4mm,r=5.5mm,截面面积3.897cm2,理论重量3.059公斤/米，外表面积0.197米2/米b=50mm,d=5mm,r=5.5mm,截面面积4.803cm2,理论重量3.770公斤/米，外表面积0.196米2/米b=50mm,d=6mm,r=5.5mm,截面面积5.688cm2,理论重量4.465公斤/米，外表面积0.196米2/米轻槽12：截面高度H=120mm；截面宽度B=52mm；翼缘厚度tf=4.8mm；腹板厚度tw=7.8mm；中和轴距离z0=15.4mm；截面面积A=1330mm2；惯性矩Ix=3010000mm4；惯性矩Iy=312000mm4；截面模量Wx=50167mm3；五、工字钢单位重量表热轧普通工字钢每米重量表型号尺寸（毫米）截面面积（厘米2）理论重量（公斤/米）hbdtr110100684.57.63.314.311.212.61267458.43.518.114.214140805.59.13.821.516.9161608869.9426.120.518180946.510.74.330.624.120a200100711.44.535.527.920b200102911.44.539.531.122a2201107.512.34.8423322b2201129.512.34.846.436.425a250116813548.538.125b2501181013553.54228a2801228.513.75.355.4543.428b28012410.513.75.361.0547.932a3201309.5155.867.0552.732b32013211.5155.873.4557.732c32013413.5155.879.9562.836a3601361015.8676.359.936b3601381215.8683.565.636c3601401415.8690.771.240a40014210.516.56.386.167.640b40014412.516.56.394.173.840c40014614.516.56.310280.145a45015011.5186.810280.445b45015213.5186.811187.445c45015415.5186.812094.550a5001581220711993.650b5001601420712910150c5001621620713910956a56016612.5217.3135.25106.256b56016814.5217.3146.4511556c56017016.5217.3157.85123.963a63017613227.5154.9121.663b63017815227.5167.5131.563c63018017227.5180.1141热轧轻型工字钢每米重量表型号尺寸（毫米）截面面积（厘米2）理论重量(公斤/米)型号尺寸（毫米）截面面积（厘米2）理论重量(公斤/米)hbdthbdt10100554.57.212.09.4618180905.18.123.418.412120644.87.314.711.518a1801005.18.325.419.914140734.97.517.413.7202001005.28.426.821.016160815.07.820.21520a2001105.28.628.922.7222201105.48.730.624.0404001558.013.071.456.122a2201205.48.932.825.8454501608.614.283.065.2242401155.69.534.827.3505001709.515.297.876.824a2401255.69.837.529.45555018010.316.511489.8272701256.09.840.231.56060019011.117.813210427a2701356.010.243.233.9656502001219.2153120303001356.510.246.536.5707002101320.817613830a3001456.510.749.939.270a7002101524.0202158333301407.011.253.842.270b70021017.528.2234184363601457.512.361.948.6六、槽钢单位重量表热轧普通槽钢每米重量表型号尺寸（毫米）截面面积（厘米2）理论重量(公斤/米)型号尺寸（毫米）截面面积（厘米2）理论重量(公斤/米)hbdthbdt550374.576.935.4414a1405869.518.5114.536.363404.87.58.4446.6314b1406089.521.3116.738804358110.248.0416a160636.51021.9517.2310100485.38.512.741016160658.51025.1519.7412.6126535.5915.6912.3718a18068710.525.6920.171818070910.529.2922.9928c2808611.512.551.2240.2120a2007371128.8322.6332a3208881448.7038.22202007591132.8325.7732b32090101455.1043.2522a22077711.531.8424.9932c32092121461.5048.282222079911.536.2428.4536a3609691660.8947.8025a2507871234.9127.4736b36098111668.0953.4525b2508091239.9131.3936c360100131675.2950.1025c25082111244.9135.3240a40010010.51875.0558.9128a280827.512.540.0231.4240b40010212.51883.0565.1928b280849.912.545.6235.8140c40010414.51891.0571.47热轧轻型槽钢每米重量表型号尺寸（毫米）截面面积（厘米2）理论重量（公斤/米）hbdtr1550324.47.02.56.164.846.565364.47.22.57.515.90880404.57.42.58.897.0510100464.57.63.010.908.5912120524.87.83.013.3010.414140584.98.13.015.6012.314a140624.98.73.017.0013.316160645.08.43.518.1014.216a160685.09.03.519.5015.318180705.18.73.520.7016.318a180745.19.33.522.2017.420200765.29.04.023.418.420a200805.29.74.025.219.822220825.49.54.026.721.022a220875.410.24.028.822.624240905.610.04.030.624.024a240955.610.74.032.925.827270956.010.54.535.227.7303001006.511.0540.531.8333301057.011.7546.536.5363601107.512.6653.441.9404001158.013.5661.548.3七、轨道材料重量表钢轨每米重量表钢轨类型(公斤/米)尺寸（毫米）截面面积F(厘米2)理论重量(公斤/米)高A度底B宽头C宽腰D厚轻轨55044224.56.415.0386554257.010.768.421180.566327.014.3111.20159176377.018.8014.721890804010.023.0718.0624107925110.931.2424.46重轨331201106012.542.533.28638134114681349.538.73431401147014.557.044.653501521327015.565.851.514鱼尾板每块重量表钢轨类型尺寸（毫米）横截面面积(厘米2)每块加工后的重量(公斤)鱼尾板标准号ABCD5公斤/米2122652561.760.269YB229-638公斤/米2703070703.490.687YB228-6311公斤/米35832100947.111.91YB227-6315公斤/米3723610010010.122.78YB226-6318公斤/米扁平型372361001008.52.33YB225-63角型10.93.0324公斤/米4265010012614.864.73YB14-6333公斤/米3843公斤/米5907906516014021.1226.019.4115.57YB351-63YB185-63六、槽钢单位重量表热轧普通槽钢每米重量表型号尺寸（毫米）截面面积（厘米2）理论重量(公斤/米)型号尺寸（毫米）截面面积（厘米2）理论重量(公斤/米)hbdthbdt550374.576.935.4414a1405869.518.5114.536.363404.87.58.4446.6314b1406089.521.3116.738804358110.248.0416a160636.51021.9517.2310100485.38.512.741016160658.51025.1519.7412.6126535.5915.6912.3718a18068710.525.6920.171818070910.529.2922.9928c2808611.512.551.2240.2120a2007371128.8322.6332a3208881448.7038.22202007591132.8325.7732b32090101455.1043.2522a22077711.531.8424.9932c32092121461.5048.282222079911.536.24
