Angle steel commonly known as Angle iron, is perpendicular to each other on both sides of the Angle shape of the long steel. There are equal-edge Angle steel and non-equal-edge Angle steel.
The two sides of an equal-sided Angle are of equal width. The specification is expressed in millimeters of edge width × edge width × edge thickness. Such as "∟ 30 * 30 * 3", it indicates that the width of 30 mm, while equal Angle steel thickness is 3 mm. Also available model, said the model is the number of centimeters wide, such as ∟ 3 #. The model number does not indicate the size of different side thickness in the same model. Therefore, the side width and side thickness of Angle steel shall be fully filled in in the contract and other documents, avoiding using the model number alone.
