鍍(du)鋅H型(xing)鋼現(xian)貨 Q235B熱鍍(du)鋅H型(xing)鋼 Q345B鍍(du)鋅H型(xing)鋼 鋼梁專用

H型鋼(gang)是一種(zhong)截(jie)面(mian)面(mian)積分(fen)配更(geng)加優化、強(qiang)重比更(geng)加合理的經濟斷面(mian)高效型材，因其(qi)斷面(mian)與英文字母“H”相同而(er)得名(ming)。由于H型鋼(gang)的各(ge)個部位均以直(zhi)角排布，因此H型鋼(gang)在各(ge)個方向上都(dou)具(ju)有抗彎能力強(qiang)、施工簡單、節約成(cheng)本和(he)結構重量(liang)輕等優點，已被廣泛應(ying)用。

H型(xing)鋼(gang)的翼緣內外側(ce)平(ping)(ping)行(xing)(xing)或(huo)接近于平(ping)(ping)行(xing)(xing)，翼緣端(duan)部(bu)呈(cheng)直角(jiao)，因此(ci)而(er)得(de)名(ming)平(ping)(ping)行(xing)(xing)翼緣工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)。H型(xing)鋼(gang)的腹板(ban)厚度(du)比腹板(ban)同(tong)(tong)(tong)樣(yang)(yang)(yang)高(gao)的普(pu)(pu)(pu)通(tong)工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)小，翼緣寬度(du)比腹板(ban)同(tong)(tong)(tong)樣(yang)(yang)(yang)高(gao)的普(pu)(pu)(pu)通(tong)工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)大(da)，因此(ci)又得(de)名(ming)寬緣工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)。由(you)形狀所決(jue)定，H型(xing)鋼(gang)的截面(mian)模數(shu)、慣性矩(ju)及相(xiang)應的強度(du)均明顯優于同(tong)(tong)(tong)樣(yang)(yang)(yang)單(dan)重的普(pu)(pu)(pu)通(tong)工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)。用在不同(tong)(tong)(tong)要求的金屬結(jie)構中，不論是承受彎曲力矩(ju)、壓力負荷、偏心負荷都顯示出它(ta)的優越性能(neng)，可(ke)較普(pu)(pu)(pu)通(tong)工(gong)(gong)(gong)(gong)字(zi)(zi)(zi)鋼(gang)大(da)大(da)提高(gao)承載能(neng)力，節(jie)約金屬10%～40%。H型(xing)鋼(gang)的翼緣寬、腹板(ban)薄、規格多、使(shi)用靈活，用于各種桁架(jia)結(jie)構中可(ke)節(jie)約金屬15%～20%。由(you)于其翼緣內外側(ce)平(ping)(ping)行(xing)(xing)，緣端(duan)呈(cheng)直角(jiao)，便于拼(pin)裝組合成各種構件，從而(er)可(ke)節(jie)約焊接、鉚接工(gong)(gong)(gong)(gong)作(zuo)量25%左右，能(neng)大(da)大(da)加快工(gong)(gong)(gong)(gong)程的建設(she)速(su)度(du)，縮短工(gong)(gong)(gong)(gong)期。

由于(yu)具有(you)上述優點(dian)，H型鋼應用廣泛，主要用于(yu)：各(ge)種(zhong)民用和工(gong)業(ye)建筑結構;各(ge)種(zhong)大(da)(da)跨(kua)度的(de)工(gong)業(ye)廠房(fang)和現代化(hua)高層建筑，尤其是地(di)震活(huo)動頻(pin)繁地(di)區和高溫工(gong)作(zuo)條件下的(de)工(gong)業(ye)廠房(fang);要求(qiu)承載能(neng)力大(da)(da)、截面穩定性好(hao)、跨(kua)度大(da)(da)的(de)大(da)(da)型橋梁;重型設備;高速公路;艦船骨架;礦山支護;地(di)基(ji)處理和堤壩工(gong)程;各(ge)種(zhong)機器構件。
