style="text-indent:25px">H型鋼截面形狀經(jīng)濟合理，力學性能好，軋制時截面上各點延伸較均勻、內(nèi)應力小，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，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25%。常用于要求承截能力大，截面穩(wěn)定性好的大型建筑（如廠房、高層建筑等），以及橋梁、船舶、起重運輸機械、設備基礎、支架、基礎樁等。H型鋼是由工字型鋼優(yōu)化發(fā)展而成的一種斷面力學性能更為優(yōu)良的經(jīng)濟型斷面鋼材，尤其斷面與英文字母“H”相同而得名。鍍鋅鋼管管口對接后出現(xiàn)兩支管口對接不嚴現(xiàn)象，導致焊口薄厚不均勻。</p><div
