1、外型不一樣，圓鋼外型光圓，無紋無肋，其它鋼筋表面外型有刻紋或有肋，這樣就造成圓鋼與混凝土的粘結(jié)力小，而其它鋼筋與混凝土的粘結(jié)力大。 </p> <p> 2、成份不一樣，圓鋼(一級(jí)鋼)屬于普通低碳鋼，其它鋼筋多為合金鋼。 </p> <p> 3、強(qiáng)度不一樣，圓鋼強(qiáng)度低，其它鋼強(qiáng)度高，即直徑大小相同的圓鋼與其它鋼筋相比，圓鋼所能承受的拉力要比其它鋼筋小，但圓鋼的塑性比其它鋼筋強(qiáng)，即圓鋼在被拉斷前有較大的變形，而其它鋼筋在被拉斷前的變形要小得多。 </p> <p> 圓鋼理論重量計(jì)算公式：外徑Х外徑Х0.00617=kg/m

H型鋼是一種截面面積分配更加優(yōu)化、強(qiáng)重比更加合理的經(jīng)濟(jì)斷面高效型材，因其斷面與英文字母“H”相同而得名。由于H型鋼的各個(gè)部位均以直角排布，因此H型鋼在各個(gè)方向上都具有抗彎能力強(qiáng)、施工簡(jiǎn)單、節(jié)約成本和結(jié)構(gòu)重量輕等優(yōu)點(diǎn)，已被廣泛應(yīng)用。 </p> <p> H型鋼的翼緣內(nèi)外側(cè)平行或接近于平行，翼緣端部呈直角，因此而得名平行翼緣工字鋼。H型鋼的腹板厚度比腹板同樣高的普通工字鋼小，翼緣寬度比腹板同樣高的普通工字鋼大，因此又得名寬緣工字鋼。由形狀所決定，H型鋼的截面模數(shù)、慣性矩及相應(yīng)的強(qiáng)度均明顯優(yōu)于同樣單重的普通工字鋼。用在不同要求的金屬結(jié)構(gòu)中，不論是承受彎曲力矩、壓力負(fù)荷、偏心負(fù)荷都顯示出它的優(yōu)越性能，可較普通工字鋼較大提高承載能力，節(jié)約金屬10%～40%。H型鋼的翼緣寬、腹板薄、規(guī)格多、使用靈活，用于各種桁架結(jié)構(gòu)中可節(jié)約金屬15%～20%。由于其翼緣內(nèi)外側(cè)平行，緣端呈直角，便于拼裝組合成各種構(gòu)件，從而可節(jié)約焊接、鉚接工作量25%左右，能較大加快工程的建設(shè)速度，縮短工期。 </p><p style="text-indent:25px">工字型鋼不論是普通型還是輕型的，由于截面尺寸均相對(duì)較高、較窄，故對(duì)截面兩個(gè)主軸的慣性矩相差較大，故*能直接用于在其腹板平面內(nèi)受彎的構(gòu)件或?qū)⑵浣M成格構(gòu)式受力構(gòu)件。對(duì)軸心受壓構(gòu)件或在垂直于腹板平面還有彎曲的構(gòu)件均不宜采用，這就使其在應(yīng)用范圍上有著很大的局限。工字鋼應(yīng)用于建筑或其他金屬結(jié)構(gòu)。普通工字鋼，輕型工字鋼，由于截面尺寸均相對(duì)較高、較窄，故對(duì)截面兩個(gè)主軸的慣性矩相差較大，這就使其在應(yīng)用范圍上有著很大的局限。工字鋼的使用應(yīng)依據(jù)設(shè)計(jì)圖紙的要求進(jìn)行選用。在結(jié)構(gòu)設(shè)計(jì)中選用工字鋼應(yīng)依據(jù)其力學(xué)性能，化學(xué)性能，可焊性能，結(jié)構(gòu)尺寸等選擇合理的工字鋼進(jìn)行使用。想要購買中板，就選江陰市港都物資有限公司，讓您滿意，期待您的光臨！</p><div
