Angle Steel

ASTM A36 Angle Steel Bar is a type of low-carbon structural steel angle produced in accordance with the ASTM A36/A36M standard. It features a yield strength of at least 250 MPa and is available in both Steel Equal Angle and Unequal Angle Steel Bar; it is widely used in construction, bridges, and general steel structures.

Equal angle steel bars, commonly known as angle iron, are long steel sections with two legs of equal length positioned perpendicular to each other, forming an L-shaped cross-section. Compared to unequal angle steel bar, equal angle steel offers a larger cross-sectional area and superior symmetry for the same weight, resulting in higher strength and greater stability. They are widely used in applications requiring resistance to bending moments and shear forces, such as building beams, power transmission towers, lifting equipment, bridges, and industrial facility frameworks.

Stainless steel angle bars are long steel sections with two sides forming a right angle, resembling the letter “L” in cross-section. Characterized by corrosion resistance, high strength, and good weldability, they are widely used in fields such as building frameworks, bridges, and machinery manufacturing. They are categorized into equal-leg and unequal-leg angles; unequal-leg angles are further subdivided into those with uniform thickness and those with varying thickness.

Unequal angle steel bar refers to the angle steel bars with a right-angled L-shaped cross-section and two sides of unequal length. Unequal angle steel bar can be divided into two types: unequal-angle equal-thickness angle steel and unequal-angle unequal-thickness angle steel.
