style="text-indent:25px">螺紋鋼是中型以上建筑構(gòu)件必須用鋼材，中國(guó)每年都有一定進(jìn)口批量。主要生產(chǎn)國(guó)和地區(qū)為日本、西歐。出口螺紋鋼的數(shù)量有所增長(zhǎng)，國(guó)內(nèi)主要出口生產(chǎn)廠家為北京、天津、上海、武漢、四川、遼寧等省市的鋼鐵企業(yè)。輸往地區(qū)主要為港澳及東南亞地區(qū)。進(jìn)口螺紋鋼的橫肋幾何形狀主要為普通方形螺紋或普通斜方形螺紋。國(guó)產(chǎn)螺紋鋼的橫肋幾何形狀主要有螺旋形、人字形、月牙形三種。螺紋鋼的定貨原則一般是在滿足工程設(shè)計(jì)所需握緊性能要求的基礎(chǔ)上，以機(jī)械工藝性能或機(jī)械強(qiáng)度指標(biāo)為主。</p><p> 螺紋鋼常用的分類(lèi)方法有兩種：一是以幾何形狀分類(lèi)，根據(jù)橫肋的截面形狀及肋的間距不同進(jìn)行分類(lèi)或分型，如英國(guó)標(biāo)準(zhǔn)（BS4449）中，將螺紋鋼分為Ⅰ型、Ⅱ型。這種分類(lèi)方式主要反應(yīng)螺紋鋼的握緊性能。二是以性能分類(lèi)（級(jí)），例如我國(guó)現(xiàn)行執(zhí)行標(biāo)準(zhǔn)，螺紋鋼為（G）線材為）中，按強(qiáng)度級(jí)別（屈服點(diǎn)/抗拉強(qiáng)度）將螺紋鋼分為3個(gè)等級(jí)；日本工業(yè)標(biāo)準(zhǔn)（JISG3112）中，按綜合性能將螺紋鋼分為5個(gè)種類(lèi)；英國(guó)標(biāo)準(zhǔn)（BS4461）中，也規(guī)定了螺紋鋼性能試驗(yàn)的若干等級(jí)。此外還可按用途對(duì)螺紋鋼進(jìn)行分類(lèi)，如分為鋼筋混凝土用普通鋼筋及預(yù)應(yīng)力鋼筋混凝土用熱處理鋼筋等。螺紋鋼的規(guī)格要求應(yīng)在進(jìn)出口貿(mào)易合同中列明。一般應(yīng)包括標(biāo)準(zhǔn)的牌號(hào)（種類(lèi)代號(hào)）、鋼筋的公稱(chēng)直徑、公稱(chēng)重量（質(zhì)量）、規(guī)定長(zhǎng)度及上述指標(biāo)的允差值等各項(xiàng)。我國(guó)標(biāo)準(zhǔn)推薦公稱(chēng)直徑為6、8、10、12、16、20、25、32、40、50mm的螺紋鋼系列。供貨長(zhǎng)度分定尺和倍尺二種。我國(guó)出口螺紋鋼定尺選擇范圍為6～12m，日本產(chǎn)螺紋鋼定尺選擇范圍為～10m；國(guó)產(chǎn)內(nèi)銷(xiāo)螺紋鋼若合同中無(wú)注明要求時(shí)，通常定尺為9m、12m兩個(gè)長(zhǎng)度。螺紋鋼材價(jià)格專(zhuān)業(yè)廠家批發(fā)？報(bào)價(jià)新出爐！來(lái)了解下！</p><div
