MS Angles are L-shaped structural steel with consistent dimensions on both sides. For example, 50x50x6 denotes that both sides of the angles are 50 mm long and the consistency is 6 mm. Angles of various sizes, both equal and unstable, can be found.

Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, and weapons. Iron is the base metal of steel.
