角鋼

角(jiao)鋼：不(bu)(bu)(bu)銹(xiu)(xiu)鋼角(jiao)鋼是(shi)兩(liang)邊(bian)(bian)(bian)互(hu)相垂(chui)直成角(jiao)形的長條(tiao)鋼材。有等(deng)(deng)邊(bian)(bian)(bian)不(bu)(bu)(bu)銹(xiu)(xiu)鋼角(jiao)鋼和不(bu)(bu)(bu)等(deng)(deng)邊(bian)(bian)(bian)不(bu)(bu)(bu)銹(xiu)(xiu)鋼角(jiao)鋼之分。等(deng)(deng)邊(bian)(bian)(bian)不(bu)(bu)(bu)銹(xiu)(xiu)鋼角(jiao)鋼的 兩(liang)個邊(bian)(bian)(bian)寬相等(deng)(deng)。其規格以邊(bian)(bian)(bian)寬×邊(bian)(bian)(bian)寬×邊(bian)(bian)(bian)厚的毫米(mi)數表示。如"∠25×25×3"，即(ji)表示邊(bian)(bian)(bian)寬為 30毫米(mi)、邊(bian)(bian)(bian)厚為3毫米(mi)的等(deng)(deng)邊(bian)(bian)(bian)不(bu)(bu)(bu)銹(xiu)(xiu)鋼角(jiao)鋼。也可用型號表示，型號是(shi)邊(bian)(bian)(bian)寬的厘米(mi)數，如∠3#。型號不(bu)(bu)(bu)表示同(tong)一型號中不(bu)(bu)(bu)同(tong)邊(bian)(bian)(bian)厚的尺(chi)寸，因(yin)而在(zai)合同(tong)等(deng)(deng)單據上將不(bu)(bu)(bu)銹(xiu)(xiu)鋼角(jiao)鋼的邊(bian)(bian)(bian)寬、邊(bian)(bian)(bian)厚尺(chi)寸填寫(xie)齊(qi)全，避免單獨(du)用型號表示。
