        角钢—分等边角钢和不等边角钢两种。不等边角钢的规格用边长和边厚的尺寸表示。指断面为角形且两边长不相等的钢材。是角钢中的一种。其边长由25mm×16mm~200mm×125mm。由热轧轧机轧制而成。不等边角钢广泛应用于各种金属结构、桥梁、机械制造与造船业等。 

        在工程材料领域里,相对于两个边长相等的等边角钢而言,指断面为直角L型形且两边长不相等的角钢。它被广泛地用于,各种市政公用、民用建筑及军事工业的结构和工程结构,如工业房梁、桥梁、输电塔、起重运输机械、船舶、工业炉、反应塔、容器架、以及仓库等,因其用量较单边角钢为少,所以相对价格略高。 

        不等边角钢的表面质量在标准中有规定,一般要求不得存在使用上有害的缺陷,如分层、结疤、裂缝等。 

        不等边角钢几何形状偏差的允许范围在标准中也有规定,一般包括弯曲度、边宽、边厚、顶角、理论重量等项,并规定不等边角钢不得有显著的扭转。 

        不等边角钢是横截面如字母L,两边互相垂直成角形且宽度不等的长条钢材。 其规格以长边宽*短边宽*边厚的毫米数表示,如“L30*20*3”,即表示长边宽30mm、短 边宽20mm、边厚为3mm的不等边角钢。也可以用型号(号数)表示,型号用一分数表示,分子为长边宽的厘米数,分母为短边宽的厘米数,如“L3/2#”,3表示长边的厘米数,2表示短边的厘米数。不等边角钢的规格范围为2.5/1.6#-20/12.5#。 

等边角钢的规格以边宽*边宽*边厚的毫米数表示

        如:30*30*3,即表示边宽为30mm、 边厚为3mm的等边角钢。也可用型号(号数)表示,型号是边宽的厘米数。

        角钢型号前面可加符号“∠”,型号后边右上角可加符号“#”,如:∠30#。 等边角钢的规格范围为2#-20#。  

        不等边角钢的规格及重量计算方法 每米重量=0.00785*(边宽+边宽-边厚)*边厚。
