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#. 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#.
