Product Description
Our Steel Angle 1-1/2" X 1-1/2" X 3/16" is manufactured to ASTM A36 specifications, delivering exceptional structural performance for a wide range of industrial and construction applications. This hot-rolled angle bar features equal legs of 1-1/2 inches with a 3/16-inch thickness, providing an optimal balance between strength, weight, and usability. The material is produced through a rigorous rolling process that ensures consistent mechanical properties, dimensional accuracy, and excellent workability.
ASTM A36 carbon steel is the industry standard for general structural purposes, renowned for its outstanding combination of strength, weldability, and availability. This angle bar is ideal for frameworks, supports, braces, and connections in buildings, bridges, machinery, and equipment. The equal-leg design allows for symmetrical load distribution and simplified connection details, making installation efficient and cost-effective. Each piece undergoes quality control testing to verify compliance with yield strength, tensile strength, and elongation requirements.
The versatility of this steel angle extends to multiple fabrication methods including welding, bolting, and riveting, accommodating both traditional and modern construction techniques. Whether utilized as a main structural member or as supplementary bracing and reinforcement, this material performs reliably under static and dynamic loads. The hot-rolled surface finish provides natural oxidation resistance for outdoor installations and excellent paint adhesion for protective coating systems.
Rigorous material testing and strict quality standards ensure that every angle bar meets ASTM A36 specifications, delivering predictable performance and long-term reliability. Our commitment to quality extends from raw material selection through final inspection, guaranteeing that your structural components maintain their integrity throughout their service life in demanding industrial environments.
