角钢的几何偏差允许范围也是有规定的，包括弯曲度、边宽、边沿厚度、顶角、理论重量等，并且规定角钢不应有明显的扭转。 生产和实际使用中主要以形状分类。角钢的规格用边长和边厚的尺寸表示。目前国产角钢规格为2-20号，以边长的厘米数为号数， 同一号角钢常有2-7种不同的边厚。进口角钢标明两边的实际尺寸及边厚并注明相关标准。一般边长5cm以下的为小型角钢， 12.5cm—5cm之间的为中型角钢，边长12.5cm以上的为大型角钢。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，如房梁、桥梁、船舶、工业炉、容器架以及仓库货架等；用于制做框架结构，例如高压输电的塔架、 钢结构桥梁主梁两侧的框架、建筑工地上塔式起重机的立柱和臂杆、车间的立柱和梁等，小的地方如过节路边摆花盆造型的架子、 在窗户下挂空调太阳能的架子等；。 The allowable range of geometric deviation of angle steel is also specified, including curvature, edge width, edge thickness, top angle, theoretical weight, etc., and stipulates that angle steel shall not have obvious torsion.In production and actual use, it is mainly classified by shape.The specifications of the angle steel are indicated by the dimensions of the edge length and edge thickness. At present, domestic corner steel specifications for 2-20, with the number of centimeters for the number, the same horn steel often has 2-7 different side thickness. The inlet angle steel indicates the actual size and side thickness of both sides and indicates the relevant standards. General side length below 5cm is small corner steel, between 12.5cm and 5cm is medium corner steel, and the side length above 12.5cm is large corner steel.Angle steel can be composed of different stressed components, such as beams, bridges, ships, industrial furnace, container shelves and warehouse shelves, etc.; for making frame structure, such as high voltage transmission tower, both sides of the main bridge, columns and arms of tower crane, workshop columns and beams, small places such as holiday roadside pot shelves, air conditioning and solar shelves under the window, etc..
