Angle

About

Carbon steel angle is a hot rolled, low carbon, low alloy steel, that has been shaped into a 90 degree angle. It is available in a variety of sizes, making it ideal for structural applications, general fabrication, machining, and repairs. Here are some of the products that we offer:



ASTM A36 ANGLE


ASTM A36 angle is one of the most widely used carbon steels by the construction industry. It is a low-cost material compared to specialty steels and exhibits the strength required for structural applications. In addition, it is weldable, formable, and machinable. Galvanizing the steel increases its resistance to corrosion.


APPLICATIONS

ASTM A36 steel angle is used in a range of industrial applications, including machinery and Equipment Frames (Braces and Corners), Transportation Frames and Corners, Support frames that require welding, riveting or bolting on bridges and buildings, General structural use in construction, ...



A529-50 STEEL ANGLE


ASTM A529-50 carbon steel angle is stronger than the more common A36 steel angle and meets a 50K minimum yield strength. It is easy to weld, rivet and bolt, as well as machine and fabricate.


APPLICATIONS

ASTM A529-50 steel is generally used in the construction of buildings, bridges, and other structures for support and structural components.



ASTM A572-50 ANGLE


ASTM A572-50 is a high-strength, low-alloy (HSLA) columbium-vanadium steel. It has a higher yield and tensile strength, as compared to ASTM A36. The higher tensile strength of A572-50 allows reduction of section thickness and weight when manufacturing parts, therefore lowering the overall weight of the part. It is easy to weld, form, and machine when using appropriate techniques.
ASTM A572 is also available in grades 42, 55, 60 and 65.


APPLICATIONS

A572-50 is used in transportation and other applications that require increased strength at a lower weight. For transportation operations, it provides added payload capacity with a lower increase in equipment weight, reducing operating costs. A572-50 is also used in the construction of bridges and buildings.



ASTM A588 ANGLE


ASTM A588 is a high-strength, low-alloy (HSLA) steel containing small added amounts of copper, chromium and nickel. It is often left unpainted as it develops a weathered, orange-brown surface that is resistant to atmospheric corrosion, and thus leads to a longer life for weather-exposed applications. Its strength-to-weight ratio, and overall strengthening properties are similar to those of A572 steel.


APPLICATIONS

ASTM A588 is used in applications where savings in weight and/ or added durability (for corrosion resistance) are important. Such applications include: bridges, buildings, freight cars, construction equipment, smoke-stack liners, precipitators, transmission towers, and streetlight poles.
