Angle iron, commonly known as angle steel, is a long strip of steel with two sides forming a right angle to each other.Equal Angle SteelEqual angle steel differs from unequal angle steel. Equal angle steel has two sides with equal widths. Its specifications are indicated by the millimeter measurements of side width × side width × side thickness. For example, "∟30×30×3" indicates equal angle steel with a side width of 30 millimeters and a side thickness of 3 millimeters.

Model numbers can also be used, which represent the millimeter width of the edge, such as ∟3#. Model numbers do not indicate the thickness variations within the same model, so it is essential to fill in the width and thickness dimensions of angle steel on contracts and other documents to avoid relying solely on the model number. The specifications for hot-rolled equal angle steel range from 2# to 20#. Angle steel can be assembled into various configurations to meet different structural requirements.Component, also serves as an inter-component componentFastenerWidely used in various architectural structures.Engineering Structure, such asRafterBridges, transmission towers.Lifting and transportation machineryShips,Industrial FurnaceReaction tower, container racks, and warehouse.
