Angle Steel (Angle Iron) is an L-shaped structural steel with two perpendicular arms, available in equal or unequal lengths. Made from carbon steel, it offers high strength, corrosion resistance, and durability. Commonly hot-rolled or cold-formed, it is widely used in construction (frames, brackets), machinery, bridges, and infrastructure. Its right-angle design ensures stability, while lightweight properties simplify installation. Surface treatments like galvanizing or painting enhance longevity.
