二級(jí)螺紋鋼和三級(jí)螺紋鋼的區(qū)別（不同點(diǎn)）首先我們帶大家了解一下什么是二級(jí)螺紋鋼，什么是三級(jí)螺紋鋼。二級(jí)螺紋鋼：即新標(biāo)準(zhǔn)名稱為HRB335的鋼筋，二級(jí)螺紋鋼為舊稱，為熱軋帶肋鋼筋的一種。螺紋鋼在建筑業(yè)中，Ⅱ級(jí)螺紋鋼和Ⅲ級(jí)螺紋鋼是過(guò)去的叫法，新標(biāo)準(zhǔn)中，Ⅱ級(jí)螺紋鋼稱為HRB335。普遍用于房屋，昌吉高質(zhì)量花紋螺紋鋼、橋梁、道路等土建工程建設(shè)。三級(jí)螺紋鋼：即新標(biāo)準(zhǔn)名稱為HRB400的鋼筋，昌吉高質(zhì)量花紋螺紋鋼，三級(jí)螺紋鋼為舊稱，為熱軋帶肋鋼筋的一種。在建筑業(yè)中，三級(jí)螺紋鋼是過(guò)去的叫法。熱軋帶肋鋼筋的牌號(hào)由HRB和牌號(hào)的屈服點(diǎn)最小值構(gòu)成。H、R、B分別為熱軋（Hotrolled）、帶肋（Ribbed）、鋼筋（Bars）三個(gè)詞的英文**字母。其實(shí)從定義上我們只能看出二級(jí)螺紋鋼和三級(jí)螺紋鋼只是在材質(zhì)上有所不同，一個(gè)是hrb335，一個(gè)是hrb400，昌吉高質(zhì)量花紋螺紋鋼。反而從定義上我們更多的是可以看出兩者的相同點(diǎn)，都屬于普通低合金熱軋鋼筋；都屬于帶肋鋼筋（即通常說(shuō)的螺紋鋼筋）；都可以用于普通鋼筋混凝土結(jié)構(gòu)工程中。既然這樣我們就仔細(xì)的來(lái)分析一下二級(jí)螺紋鋼和三級(jí)螺紋鋼的區(qū)別與不同點(diǎn)：1、鋼種不同，（化學(xué)成份不同）。HRB335級(jí)鋼筋是20MnSi(20錳硅)；HRB400級(jí)鋼筋是20MnSiV或20MnSiNb或20MnTi等；2.強(qiáng)度不同。螺紋鋼大量現(xiàn)貨供應(yīng)，來(lái)這里就對(duì)了！昌吉高質(zhì)量花紋螺紋鋼</p><div

螺紋鋼是表面帶肋的鋼筋，亦稱帶肋鋼筋，通常帶有2道縱肋和沿長(zhǎng)度方向均勻分布的橫肋。橫肋的外形為螺旋形、人字形、月牙形3種。用公稱直徑的毫米數(shù)表示。帶肋鋼筋的公稱直徑相當(dāng)于橫截面相等的光圓鋼筋的公稱直徑。鋼筋的公稱直徑為8-50毫米，推薦采用的直徑為8、12、16、20、25、32、40毫米。帶肋鋼筋在混凝土中主要承受拉應(yīng)力。帶肋鋼筋由于肋的作用，和混凝土有較大的粘結(jié)能力，因而能更好地承受外力的作用。帶肋鋼筋普遍用于各種建筑結(jié)構(gòu)、特別是大型、重型、輕型薄壁和高層建筑結(jié)構(gòu)。①表面質(zhì)量。有關(guān)標(biāo)準(zhǔn)中對(duì)螺紋鋼的表面質(zhì)量作了規(guī)定，要求端頭應(yīng)切得平直，表面不得有裂縫、結(jié)疤和折疊，不得存在使用上有害的缺點(diǎn)等。②外形尺寸偏差允許值。螺紋鋼的彎曲度及鋼筋幾何形狀的要求在有關(guān)標(biāo)準(zhǔn)中作了規(guī)定。昌吉高質(zhì)量花紋螺紋鋼新疆用戶注意！螺紋鋼大量現(xiàn)貨供應(yīng)！你還猶豫什么呢？</p><div

螺紋鋼和線材為主的建筑鋼材一直占據(jù)著我國(guó)鋼材生產(chǎn)的半壁江山。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)的轉(zhuǎn)移，我國(guó)板管帶材產(chǎn)銷所占的比重逐步增加，建筑鋼材所占比重逐年下降。2001-2007年，我國(guó)螺紋鋼產(chǎn)量由(小型材產(chǎn)量)增加到，但占鋼材產(chǎn)量的比重由。受經(jīng)濟(jì)危機(jī)影響，2008年螺紋鋼產(chǎn)量為，比2007年稍有下降。據(jù)國(guó)家統(tǒng)計(jì)局比較新數(shù)據(jù)顯示，2009年1-9月螺紋鋼累計(jì)產(chǎn)量為，增長(zhǎng)。預(yù)計(jì)2009年螺紋鋼產(chǎn)能約為，實(shí)際產(chǎn)量約為。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)。螺紋鋼材價(jià)格專業(yè)廠家批發(fā)，來(lái)戳戳這吧！</p><div
