Premium Hot Rolled Steel Angle Bars for Construction Projects Stainless Steel Angle Bar Cold Drawn 304L Mill Edge and Slit Edge

Steel Angle Bar is commonly known as angle iron, is two sides perpendicular to each other into the angle of the long steel. The national standard angle is to ensure that the difference between the national standard 0.25 that is the national standard, the same angle has equal angle and unequal angle points.
Equal angle steel two side widths are equal. Its specifications are expressed in terms of the number of millimeters of side width × side width × side thickness. For example, "∠30×3" means that the width of the side is 30 mm and the thickness of the side is 3 mm. The specification of hot rolled equal angle is 2#-20#.

Angle bar belongs to the construction of carbon structural steel, is a simple section of the section steel, mainly used for metal components and plant framework. In use, it requires good weldability, plastic deformation properties and a certain degree of mechanical strength. The raw material billet for the production of angle steel is low carbon square billet, and the finished angle steel is delivered in hot rolled formed, normalized or hot rolled condition;

Angle steel can be structured according to the different needs of a variety of different stress components, can also be used as a connection between the components. Widely used in a variety of building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.
