槽鋼

概念
槽鋼是截面為凹槽形的長條鋼材。其規(guī)格以腰高(h)*腿寬(b)*腰厚(d)的毫米數(shù)表示，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右邊加a  b  c  予以區(qū)別，如25a#  25b#  25c#等。    槽鋼

分類及用途
　　槽鋼分普通槽鋼和輕型槽鋼。熱軋普通槽鋼的規(guī)格為5-40#。經(jīng)供需雙方協(xié)議供應(yīng)的熱軋變通槽鋼規(guī)格為6.5-30#。槽鋼主要用于建筑結(jié)構(gòu)、車輛制造和其它工業(yè)結(jié)構(gòu)，槽鋼還常常和工字鋼配合使用。  　　槽鋼按形狀又可分為4種：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  　　依照鋼結(jié)構(gòu)的理論來說，應(yīng)該是槽鋼翼板受力，就是說槽鋼應(yīng)該立著，而不是趴著。
主要產(chǎn)地
　　我國主要是首鋼、包鋼、萊鋼、武鋼、馬鋼、保定普瑞鋼鐵等幾家鋼廠生產(chǎn)。
