Q355D Steel angle bar Features
Angle Steel, commonly known as Angle Iron, is the two sides of each other into a vertical angle of the long steel. There are equal angle steel and unequal angle steel points. Of equal-sided Angle Steel, having two sides of equal width. The specification is expressed by the number of millimeters of side width × side width × side thickness. But if “30 × 30 × 3”, it means equal-edge angle steel with 30 mm width and 3 mm thickness. Alternatively, the model may be stated as a centimeter in width of the side, in condition of No. 3. Model number does not indicate the size of different side thickness in the same model, so the width and side thickness of angle steel should be fully filled out on the contract documents. The hot-rolled equilateral angle steel is 2 #-20 # . Angle steel can be made up of various stress components according to the different needs of the structure, and can also be used as a connecting component 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 warehouses.

Processing Technology Of Q355D Steel angle bar
Angle steel is a kind of carbon structural steel for building. It is a kind of simple section steel. It is mainly used for the metal member and the frame of workshop. Good solderability, plastic deformation property and certain mechanical strength are required in use. The raw material for producing angle steel is low carbon square billet, and the finished angle steel is delivered in hot rolling, normalizing or hot rolling state.
