Understanding Angle Iron: Types and Grades
Mild Steel Angle Iron
Mild steel angle iron is the most commonly used type. Made from low carbon steel, it offers excellent weldability and machinability, making it ideal for a wide range of applications, including structural components in buildings and frames for trailers.
Galvanized Steel Angle Iron
Galvanized angle iron is coated with zinc to enhance its corrosion resistance. This makes it suitable for outdoor applications or environments where moisture is present, such as in fences and railings.
Stainless Steel Angle Iron
Stainless steel offers superior resistance to rust and corrosion, making it an ideal choice for marine applications or chemical processing. Its aesthetic appeal also makes it popular in architectural designs.
Aluminum Angle Iron
Aluminum angle iron is lightweight, making it an excellent choice for applications where weight is a concern. It is commonly used in DIY projects and lightweight structures due to its ease of handling and resistance to corrosion.
Applications of Angle Iron
