Angled joint sheet metal, also 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 two sides of an equilateral angle steel have equal widths. Its specifications are based on edge width × Edge width × The thickness of the edge is expressed in millimeters.
