中國(guó)鋼材消費(fèi)有著明顯的發(fā)展中國(guó)家特點(diǎn)，建筑業(yè)和工業(yè)鋼材消費(fèi)約占鋼材總消費(fèi)量的90%左右，其中建筑用鋼所占比重為50%。由于中國(guó)正處于城鎮(zhèn)化快速發(fā)展的歷史階段，對(duì)建筑鋼材需求很大。螺紋鋼作為主要的建筑用鋼材，消費(fèi)一直占據(jù)著中國(guó)鋼材生產(chǎn)的較大比重。 </p> <p> 2000年以前，小型材（以螺紋鋼為主）的比重在25%左右，2001年以后，隨著世界制造業(yè)向我國(guó)轉(zhuǎn)移，板管帶材產(chǎn)銷(xiāo)所占的比重逐步增加，而建筑鋼材所占比重逐年下降。2001-2007年，中國(guó)螺紋鋼消費(fèi)由4369.1萬(wàn)噸（小型材產(chǎn)量）增加到9551.2萬(wàn)噸，占鋼材消費(fèi)的比重由25.8%下降到18.4%。鎮(zhèn)江批發(fā)圓鋼批發(fā)價(jià)江陰市港都物資有限公司供應(yīng)圓鋼，可聯(lián)系。</p><div
