槽鋼是型鋼的一種，截面為凹槽形的長(zhǎng)條鋼材，分建筑和機(jī)械用碳素結(jié)構(gòu)鋼，是復(fù)雜斷面的型鋼鋼材，槽鋼是建筑、鋼結(jié)構(gòu)中**常用到的鋼材之一，主要用于耐腐蝕、對(duì)重量有要求的地方。槽鋼在建筑中還常常和工字鋼配合使用，在使用中具有較好的焊接、鉚接性能及綜合機(jī)械性能。槽鋼槽鋼規(guī)格尺寸：規(guī)格尺寸表示方法=h×b×d（h表示槽鋼的截面高度、b表示槽鋼腿部的截面寬度、d表示槽鋼腰部的厚度）。如120*53*5，表示腰高為120毫米，腿寬為53毫米，腰厚為5毫米的槽鋼，或稱12#槽鋼。腰高相同的槽鋼，如有幾種不同的腿寬和腰厚也需在型號(hào)右邊加a、b、c予以區(qū)別，如25a#、25b#、25c#等。槽鋼截面圖槽鋼分類：按重量分為：普通槽鋼和輕型槽鋼。在相同的高度下，輕型槽鋼比普通槽鋼的腿窄、腰薄、重量輕。其規(guī)格型號(hào)范圍從5-40#。1966年冶標(biāo)規(guī)定規(guī)格范圍從10-40#。按形狀分為：冷彎等邊槽鋼、冷彎不等邊槽鋼、冷彎內(nèi)卷邊槽鋼、冷彎外卷邊槽鋼四種。還有一種為達(dá)到更好的防腐效果生產(chǎn)時(shí)在表面鍍鋅的是熱鍍鋅槽鋼，其應(yīng)用隨著建筑、農(nóng)業(yè)的發(fā)展也相應(yīng)擴(kuò)大。槽鋼理論重量計(jì)算方法槽鋼計(jì)算公式（kg/m）W=[hd2t(b-d)(r2-r12)]（h=高；b=腿長(zhǎng)；d=腰厚；t=平均腿厚；r=內(nèi)圓弧半徑。</p><div

鍍鋅角鋼鍍鋅角鋼冷鍍鋅角鋼冷鍍鋅工藝用于保護(hù)金屬防止腐蝕，為此利用了鋅填料的涂料，在利用任何一種涂敷的方法將其涂在被保護(hù)表面，干燥之后形成鋅填料涂層，在干燥涂層中具有含量的鋅（達(dá)到95%）。適合于修理工作（即在修理工作過(guò)程中，*在被保護(hù)的鋼表面損傷的地方，只要修理好表面就可以重新涂敷）。冷鍍鋅工藝用于各種鋼制品和構(gòu)筑物的防腐。冷鍍鋅涂料主要通過(guò)電化學(xué)原理來(lái)進(jìn)行防腐，因此必須保證鋅粉與鋼材的充分接觸，產(chǎn)生電極電位差，所以鋼材表面處理很重要。噴涂冷鍍鋅前，應(yīng)選擇機(jī)械除銹(噴砂、拋丸等)，使鋼材表面清潔度達(dá)到ISO85O1—1Sa，相當(dāng)于GB8923Sa。它的文字定義為：“鋼材經(jīng)過(guò)機(jī)械除銹后，表面無(wú)油、無(wú)銹，無(wú)氧化皮及其他的污物，或*留輕微的痕跡；95%鋼材表面受到鋼丸(砂)沖擊，露出金屬的光澤。”對(duì)于表面處理質(zhì)量的另一個(gè)指標(biāo)——粗糙度，不同冷鍍鋅材料對(duì)粗糙度的要求不同。在鋅加(Zinga)的施工說(shuō)明中，要求平均粗糙度Ra=，即粗糙度Rz=55～75微米。在“強(qiáng)力鋅”及“羅巴魯”施工說(shuō)明書中，對(duì)粗糙度的要求略低，Rz=40~60微米。如果冷鍍鋅單獨(dú)成膜，作為防腐涂層時(shí)，表面粗糙度可控制得略小一點(diǎn)，以保證冷鍍鋅的涂層厚度。</p></p><br
