角钢和角铁它们是相同类型的钢，但它们的名称不同。它是用于制作架子的特殊钢材。它具有各种形状。人们打了许多长孔来拧螺丝。 它主要用于商场和工厂的货架。（这就像为方便人们放置架子而制作门窗用铝合金型材一样。）这种钢称为万能角铁或万能角钢。 角钢通常称为角铁、是一条钢带，两侧彼此垂直。等边角钢和不等角钢有两种。等边角的两侧的宽度相等。 其规格以侧面宽度x侧面宽度x侧面厚度的毫米表示。例如“∠30×30×3”，表示等边角钢，其侧边宽度为30 mm，侧边厚度为3 mm。 也可以用模型表示，其中模型是边宽的厘米数，例如∠3＃。型号不表示同一型号中不同侧面厚度的大小。因此，在合同和其他文件中， 角钢、的侧面宽度已完全填充，以避免单独使用型号。热轧等边角钢的规格为2＃-20＃。 Cape steel and corner iron they are the same type of steel, but they have different names.It is the special steel used to make the shelves. It comes in various shapes.Many long holes were made to screw them.It is used primarily in shopping malls and factory shelves. (It's like making aluminum profiles for doors and Windows for people to place shelves.) This steel is called universal angle iron or universal angle steel.Angle steel, usually called corner iron, is a steel strip, and both sides are perpendicular to each other.There are two kinds of equal edge angle steel and unequal angle steel. The sides of the equal corners are equal in width.The specification are expressed in mm of side width x side width x side thickness. For example, "30303" means equal-angle steel with a side width of 30 mm and a side thickness of 3 mm.It can also be represented by a model, where the model is the number of centimeters of edge width, such as 3 #. Model does not indicate the size of the different side thickness in the same model.Therefore, in the contract and other documents, the side width of the corner steel has been fully filled to avoid using the model alone.The specification of hot rolled equal steel is 2 # -20 #.
