工業(yè)構(gòu)dao筑物的鋼結(jié)構(gòu)承重支架；3 地下工程的鋼樁及支護(hù)結(jié)構(gòu)；4 石油化工及電力等工業(yè)設(shè)備結(jié)構(gòu)；5 大跨度鋼橋構(gòu)件；6 船舶，麗水方管定做、機(jī)械制造框架結(jié)構(gòu)； 7 火車、汽車、拖拉機(jī)大梁支架；8 港口傳送帶、高速公路檔板支架。應(yīng)用軋制H型鋼的技術(shù)合理性：工業(yè)與民用建筑中采用H型鋼不僅比常用工字鋼節(jié)省勞動(dòng)力、降低成本，而且還可降低用鋼量，麗水方管定做。如廠房鋼結(jié)構(gòu)采用熱軋工字鋼與熱軋寬翼緣H型鋼的用鋼量相比較，可降低15%-20%。與熱鍍鋅不同冷鍍鋅涂料主要通過電化學(xué)原理來進(jìn)行防腐。麗水方管定做</p><div

style="text-indent:25px">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)、施工簡單、節(jié)約成本和結(jié)構(gòu)重量輕等優(yōu)點(diǎn)，已被普遍應(yīng)用。H型鋼是一種新型經(jīng)濟(jì)建筑用鋼。H型鋼截面形狀經(jīng)濟(jì)合理，力學(xué)性能好，軋制時(shí)截面上各點(diǎn)延伸較均勻、內(nèi)應(yīng)力小，與普通工字鋼比較，具有截面模數(shù)大、重量輕、節(jié)省金屬的優(yōu)點(diǎn)，可使建筑結(jié)構(gòu)減輕30-40%；又因其腿內(nèi)外側(cè)平行，腿端是直角，拼裝組合成構(gòu)件，可節(jié)約焊接、鉚接工作量達(dá)25%。麗水方管定做熱鍍鋅鋼管在消防、電力和高速公路上有普遍的應(yīng)用。</p><div
