1、等边角钢知识角钢俗称角铁、是两边互相垂直成角形的长条钢材。有等边角钢和不等边角钢之分。等边角钢的两个边宽相等。其规格以边宽×边宽×边厚的毫米数表示。如“∠30×30×3”，即表示边宽为30毫米、边厚为3毫米的等边角钢。也可用型号表示，型号是边宽的厘米数，如∠3#。型号不表示同一型号中不同边厚的尺寸，因而在合同等单据上将角钢的边宽、边厚尺寸填写齐全，避免单独用型号表示。热轧等边角钢的规格为2#-20#。角钢可按结构的不同需要组成各种不同的受力构件，也可作构件之间的连接件。广泛地用于各种建筑结构和工程结构，如房梁、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

2、货架等。角钢属建造用碳素结构钢，是简单断面的型钢钢材，主要用于金属构件及厂房的框架等。在使用中要求有较好的可焊性、塑性变形性能及一定的机械强度。生产角钢的原料钢坯为低碳方钢坯，成品角钢为热轧成形、正火或热轧状态交货。热轧等边角钢每米重量表：角钢号数尺寸（毫米）截面面积（cm2)理论重量（kg/m)表面积(m2/m)Bbdr22033.51.1320.8890.07841.4591.1450.0772.52533.51.4321.1240.09841.8591.4590.09733034.51.7491.3730.11742.2761.7860.1173.63634.52.1
