角钢：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。 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。角钢或角铁在进行卷弯的时分， 外边被拉伸，而里面笔直的边被揉捏，所以外边被延伸，里面被揉捏，形成受力既不均匀，又是受的相反的力， 然后形成加工后的角钢产生不是90°笔直，并且很可能有褶皱产生。这种现象一般出现在5#以上角钢比较显着。 Angle steel: Angle steel commonly known as Angle iron, is both sides vertical angular shape of long steel. There are equal corner steel and unequal corner steel points.The two sides of equal ateral steel have equal width. The specifications are expressed as millimeters of edge wide edge wide edge thickness.Such as "30303", that is, indicates isobilateral steel with 30 mm edge width and 3 mm thickness of edge. Angle steel can be composed of different stressed components according to the different needs of the structure, or as a connection component between the components.It is widely used in a variety of building and engineering structures such as building beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnaces, reaction towers, container racks as well as warehouses.When the corner steel or corner iron is winding, the outside is stretched, and the straight edge inside is kneaded, so the outside is extended, the inside is kneaded, forming the force is both uneven, and the opposite force, and then form the processed corner steel production is not 90 straight, and there is likely to be folds. This phenomenon generally appears in 5 # corner steel more obvious.
