It is typically used in construction and fabrication due to its strength, versatility, and ease of installation. Angle steel comes in different sizes and thicknesses and can be made from a variety of materials, including mild steel, stainless steel, and aluminum. 

Angle steel is manufactured through the hot rolling process, where steel is rolled at high temperatures to form the desired "L" shape. It is available in two types: equal angle, where both legs of the angle are of equal length, and unequal angle, where one leg is longer than the other. The shape provides excellent structural support and load-bearing capacity, making it ideal for use in frameworks and support structures.

Characteristics of Angle Steel:

• High Strength: Angle steel offers great structural integrity, making it suitable for supporting heavy loads and acting as reinforcement in various structures.
• Versatility: Its L-shape design allows it to be used in a variety of construction applications, from framing to bracing and shelving.
• Corrosion Resistance: Depending on the material (e.g., stainless steel or galvanized steel), angle steel can offer good resistance to corrosion, especially in outdoor or marine environments.
• Ease of Installation: Angle steel is easy to cut, weld, and fasten, making it a popular choice for both large-scale construction projects and smaller fabrication tasks.
