Products Description
ASTM A36 Steel Angle is a low-carbon structural steel commonly used in the manufacture of welded and bolted metal structures for industrial and civil construction, as well as bridge building. Its excellent mechanical properties make it suitable for a wide range of structural applications.
ASTM A36 Steel Angle is also widely used in the production of various components and parts for general construction and mechanical engineering purposes, such as frames, braces, supports, and racks.

It typically has a yield strength of approximately 250 MPa, a tensile strength of 400–550 MPa, and an elongation of about 20%, ensuring good ductility and stability under load.
Typical sizes range from 20×20 mm to 200×200 mm in leg length, with thicknesses from 3 to 20 mm, making it highly versatile for different construction and fabrication needs.
