角(jiao)(jiao)鋼(gang)(gang)俗稱角(jiao)(jiao)鐵、是(shi)兩邊(bian)(bian)(bian)互相(xiang)垂直成角(jiao)(jiao)形的(de)(de)長條鋼(gang)(gang)材(cai)。有等(deng)(deng)邊(bian)(bian)(bian)角(jiao)(jiao)鋼(gang)(gang)和不(bu)(bu)等(deng)(deng)邊(bian)(bian)(bian)角(jiao)(jiao)鋼(gang)(gang)之分。等(deng)(deng)邊(bian)(bian)(bian)角(jiao)(jiao)鋼(gang)(gang)的(de)(de) 兩個邊(bian)(bian)(bian)寬(kuan)(kuan)相(xiang)等(deng)(deng)。其規(gui)格以(yi)邊(bian)(bian)(bian)寬(kuan)(kuan)×邊(bian)(bian)(bian)寬(kuan)(kuan)×邊(bian)(bian)(bian)厚(hou)(hou)的(de)(de)毫米(mi)數表示。如“∟30×30×3”，即表示邊(bian)(bian)(bian)寬(kuan)(kuan)為(wei) 30毫米(mi)、邊(bian)(bian)(bian)厚(hou)(hou)為(wei)3毫米(mi)的(de)(de)等(deng)(deng)邊(bian)(bian)(bian)角(jiao)(jiao)鋼(gang)(gang)。也(ye)可(ke)用型(xing)(xing)號表示，型(xing)(xing)號是(shi)邊(bian)(bian)(bian)寬(kuan)(kuan)的(de)(de)厘米(mi)數，如∟3#。型(xing)(xing)號不(bu)(bu)表示同(tong)(tong)(tong)一型(xing)(xing)號中不(bu)(bu)同(tong)(tong)(tong)邊(bian)(bian)(bian)厚(hou)(hou)的(de)(de)尺寸，因而在合同(tong)(tong)(tong)等(deng)(deng)單(dan)據上(shang)將角(jiao)(jiao)鋼(gang)(gang)的(de)(de)邊(bian)(bian)(bian)寬(kuan)(kuan)、邊(bian)(bian)(bian)厚(hou)(hou)尺寸填寫齊全，避免單(dan)獨用型(xing)(xing)號表示。熱(re)軋等(deng)(deng)邊(bian)(bian)(bian)角(jiao)(jiao)鋼(gang)(gang)的(de)(de)規(gui)格為(wei)2#-20#。角(jiao)(jiao)鋼(gang)(gang)可(ke)按結(jie)構的(de)(de)不(bu)(bu)同(tong)(tong)(tong)需要組成各種不(bu)(bu)同(tong)(tong)(tong)的(de)(de)受力構件(jian)，也(ye)可(ke)作構件(jian)之間的(de)(de)連接(jie)件(jian)。廣泛地用于各種建筑結(jie)構和工程結(jie)構，如房梁(liang)、橋梁(liang)、輸(shu)電塔、起重(zhong)運輸(shu)機械、船舶、工業爐、反應塔、容器架以(yi)及倉庫。
