Angle iron, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other and forming an angle shape. There are two types of angles: equal angle steel and unequal angle steel. The raw material for producing angle steel is low-carbon square steel billet, and the finished angle steel is delivered in hot rolled, normalized, or hot-rolled state.
The two sides of an equilateral angle steel have equal widths, with specifications ranging from 2 # to 20 #. Its specifications are based on edge width × Edge width × The thickness of the edge is expressed in millimeters, such as "ě 30 × thirty × 3 "refers to an equilateral angle steel with an edge width of 30 millimeters and an edge thickness of 3 millimeters. It can also be represented by a model, which is the number of centimeters of the edge width, such as {3 #. The model does not represent dimensions with different edge thicknesses within the same model. Therefore, the edge width and thickness dimensions of the angle steel should be fully filled in the contract and other documents to avoid using the model alone.
purpose
Angle steel belongs to the carbon structural steel used for construction, which is a simple cross-section steel. It can be composed of various load-bearing components according to different structural needs, and can also be used as a connection between components. It is mainly used for metal components and factory frames, and requires good weldability, plastic deformation performance, and certain mechanical strength in use. Widely used in various building and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, busbar support installation, and warehouse shelves.
