Galvanized Steel Angle Iron 20-45mm Size Range with 3-6mm Thickness Options for Structural Applications
Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other. It is divided into equal angles and unequal angles, designed to meet various structural force requirements in construction and engineering applications.
