廠家直銷建(jian)筑工程(cheng)用等邊角鋼 國標Q345B鍍鋅等邊角鋼

角(jiao)(jiao)(jiao)鋼(gang)(gang)(gang)俗稱角(jiao)(jiao)(jiao)鐵、是(shi)兩邊(bian)(bian)(bian)(bian)(bian)互相(xiang)垂直成(cheng)角(jiao)(jiao)(jiao)形的(de)(de)(de)長條鋼(gang)(gang)(gang)材。有等邊(bian)(bian)(bian)(bian)(bian)角(jiao)(jiao)(jiao)鋼(gang)(gang)(gang)和不(bu)(bu)等邊(bian)(bian)(bian)(bian)(bian)角(jiao)(jiao)(jiao)鋼(gang)(gang)(gang)之分。等邊(bian)(bian)(bian)(bian)(bian)角(jiao)(jiao)(jiao)鋼(gang)(gang)(gang)的(de)(de)(de) 兩個邊(bian)(bian)(bian)(bian)(bian)寬(kuan)(kuan)(kuan)相(xiang)等。其規格以(yi)(yi)邊(bian)(bian)(bian)(bian)(bian)寬(kuan)(kuan)(kuan)×邊(bian)(bian)(bian)(bian)(bian)寬(kuan)(kuan)(kuan)×邊(bian)(bian)(bian)(bian)(bian)厚的(de)(de)(de)毫米數表(biao)示。如“∟30×30×3”，即(ji)表(biao)示邊(bian)(bian)(bian)(bian)(bian)寬(kuan)(kuan)(kuan)為(wei) 30毫米、邊(bian)(bian)(bian)(bian)(bian)厚為(wei)3毫米的(de)(de)(de)等邊(bian)(bian)(bian)(bian)(bian)角(jiao)(jiao)(jiao)鋼(gang)(gang)(gang)。也可(ke)用(yong)型(xing)號(hao)表(biao)示，型(xing)號(hao)是(shi)邊(bian)(bian)(bian)(bian)(bian)寬(kuan)(kuan)(kuan)的(de)(de)(de)厘米數，如∟3#。型(xing)號(hao)不(bu)(bu)表(biao)示同(tong)一(yi)型(xing)號(hao)中不(bu)(bu)同(tong)邊(bian)(bian)(bian)(bian)(bian)厚的(de)(de)(de)尺(chi)寸，因而(er)在(zai)合同(tong)等單據上將角(jiao)(jiao)(jiao)鋼(gang)(gang)(gang)的(de)(de)(de)邊(bian)(bian)(bian)(bian)(bian)寬(kuan)(kuan)(kuan)、邊(bian)(bian)(bian)(bian)(bian)厚尺(chi)寸填寫齊(qi)全，避免單獨用(yong)型(xing)號(hao)表(biao)示。熱軋等邊(bian)(bian)(bian)(bian)(bian)角(jiao)(jiao)(jiao)鋼(gang)(gang)(gang)的(de)(de)(de)規格為(wei)2#-20#。角(jiao)(jiao)(jiao)鋼(gang)(gang)(gang)可(ke)按結構(gou)(gou)的(de)(de)(de)不(bu)(bu)同(tong)需要組成(cheng)各種(zhong)不(bu)(bu)同(tong)的(de)(de)(de)受(shou)力(li)構(gou)(gou)件，也可(ke)作構(gou)(gou)件之間的(de)(de)(de)連接件。廣泛地用(yong)于各種(zhong)建筑結構(gou)(gou)和工(gong)程結構(gou)(gou)，如房梁、橋梁、輸(shu)電塔、起重運輸(shu)機(ji)械、船舶、工(gong)業(ye)爐、反應塔、容器架(jia)以(yi)(yi)及倉庫。

角(jiao)鋼可按結構(gou)(gou)的不(bu)同需要(yao)組(zu)成各種(zhong)不(bu)同的受力構(gou)(gou)件(jian)，也可作構(gou)(gou)件(jian)之(zhi)間的連接件(jian)。廣(guang)泛地(di)用 

于各種建(jian)筑結(jie)(jie)構(gou)和(he)工程結(jie)(jie)構(gou)，如房(fang)梁、橋(qiao)梁、輸(shu)電塔、起重運輸(shu)機械、船舶、工業(ye)爐、反(fan)應(ying)塔、容器架、電纜(lan)溝支架、動力配管、母線支架安裝、以(yi)及倉庫貨架等。

角(jiao)(jiao)鋼(gang)(gang)(gang)屬建造用碳素結(jie)構鋼(gang)(gang)(gang)，是簡單(dan)斷面的(de)(de)(de)型鋼(gang)(gang)(gang)鋼(gang)(gang)(gang)材(cai)，主要(yao)用于金屬構件及廠房的(de)(de)(de)框架等。在(zai)使(shi)用中要(yao)求有較好(hao)的(de)(de)(de)可焊性(xing)、塑性(xing)變形(xing)(xing)性(xing)能(neng)及一定的(de)(de)(de)機械強度。角(jiao)(jiao)鋼(gang)(gang)(gang)的(de)(de)(de)原料(liao)鋼(gang)(gang)(gang)坯為低碳方鋼(gang)(gang)(gang)坯，成品角(jiao)(jiao)鋼(gang)(gang)(gang)為熱軋成形(xing)(xing)、正火或(huo)熱軋狀態交貨。
