What does the 25*3 of flange material specification (angle steel) mean?
Angle steel definition:Angle called angle, the steel strip is perpendicular to each other on both sides into the corner. There are equal angles and unequal angles. The two sides of an equal angle steel are equal in width. The specifications are expressed in millimeters of edge width * edge width * edge thickness. Such as "/ 30 x 30 x 3", that is 30 mm width equal angle, edge thickness of 3 mm. Also available models that model is the number of centimeters wide, such as angle 3#.
It can also be used as the connecting piece between the components. Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame and warehouse
The model does not mean the size of the different edges and sizes of the same model. Therefore, the width, the edge and the thickness of the angle iron should be filled out in the contract and other documents, so as not to be indicated by the model alone. Standard Specification for hot-rolled equal angle iron is 2#-20#.Application: the angle iron can be made up of different force components according to the different structure.
