General Info About A529-50 Structurals

A529 grade 50 is a particularly strong steel. It meets a standard minimum yield strength of 50,000 psi and offers outstanding weight reduction when compared to other structural steel grades.

A529 grade 50 is a high manganese, mild carbon steel with the addition of copper. It is characterized by its high strength, good corrosion resistance, toughness, and good ductility. It can be easily welded by most common weld techniques, as well as bolted, riveted, machined, and fabricated. This grade is also a popular choice for precipitation hardening, which can be significantly boost its provided strength to best suit structural support needs across a range of applications.

Because A529-50 shows an ideal combination of strength, adaptability, and corrosion resistance, it is a popular structural steel for bridge support components, high rises, framing for machinery, equipment, ceilings, and walls. It can be used as machine tracks and warehouse supports.

Kloeckner Metals supplies A529-50 beams, A529-50 angles, and A529-50 channels.

A529-50 beams are supplied in the M condition, or miscellaneous shape to provide low weight per foot. This structural steel product is most commonly seen in manufactured homes, RVs, and ship holds.

A529-50 angles offer improved corrosion resistance and hold up better in harsh weather conditions. They support in bridge and high rise construction, and various machines and manufacturing equipment. The L-shaped section can be manufactured with a 90° angle or designed to exact customer specification to satisfy requirements for a range of applications. Angles can also be provided with equal or unequal leg lengths.

A529-50 channels are widely used for high strength general building construction applications. Structural Channels and MC channels have a minimum depth of 3”.

More Details About A529 Structurals

  • Advantages/Disadvantages

    A529-50 satisfies a standard minimum yield strength of 50,000 psi. Its strength and suitability for heat and aging treatments offer outstanding weight reduction when compared to other structural steel grades. In addition to its high strength character, A529 grade 50 offers good corrosion resistance due to the inclusion of 0.20% copper in its chemical makeup. Other advantages for this structural steel grade include toughness and good ductility. One slight disadvantage of A529 grade 50 is that it cannot be oxy-fuel welded.

  • Industries

    This structural steel grade is widely used in civil engineering and general construction. A529 beams are interchangeable with A709 and A992 when it comes to providing base support in the solar industry.

  • Applications

    This structural steel grade provides excellent support for applications requiring high strength and corrosion resistance. It is suitable for riveted, bolted, and welded construction. It is frequently manufactured for bridge support components, steel high rises and warehouses, and used in equipment framing. A529-50 M beams offer critical weight reduction and are used in RVs, manufactured homes, and ship cargos. A529 beams are perfect for solar panels because they withstand outdoor conditions and provide the support needed to securely lift solar panels.

  • Machining

    This grade’s high manganese content is designed for easy machinability. It can be easily riveted, bolted, and fabricated.

  • Welding

    A529-50 can be easily welded. All common fusion and resistance methods can be used to weld this steel grade with the exception of oxyacetylene welding. Post-weld heat treatments are recommended.

  • Heat Treatment

    A529-50 is heat treatable. In fact, this structural steel grade is one of the most widely used precipitation hardening grades. A single precipitation or aging treatment will significantly impact strength.

Frequently Asked Questions About A529-50 Structurals

  • What is the difference between A529 and A572?


    One of the main differences between A529 and A572 concerns classification. A572 is a high strength low alloy structural steel while A529 (like A36) is considered a mild carbon steel. This means they each follow the applicable ASTM standards for their designated material types, and are not available in the exact same structural steel shapes. Another main difference results from variance in chemical composition. Because A529 includes 0.20% copper it offers better corrosion resistance and will be more weather hardy.

  • How are A529 beams used in the solar industry?

    The US solar industry is expanding. There are many different types of solar paneling, the kind on top of roofs and paneling that stands out in open fields. They come in various sizes and dimensions. In order to secure them, beam support is needed and A529 provides just the right combination of strength and corrosion resistance to tolerate outdoor weather conditions. Since beams can be cut to different sizes, they will fit a wide range of solar panel constructions.

  • What is the difference between beams, channels, and angles?


    Beams, channels, and angles are different types of structural steel shapes. The unique geometries of each shape correspond to specific support uses wherein each shape format adheres to typical standards.

  • What is the difference between structural angles and bar angles?


    Let’s start with what’s the same across all angles. All angles have an L-shaped cross section and can have equal or unequal leg lengths. While 90° angles are the most widely supplied, angles can be manufactured to match customer specifications.

    Now, onto their main difference: size. An angle is classified as a “bar angle” when its dimensions are less than 3”. An angle is called ‘’structural” when it exceeds 3” in at least one dimension.

    Bar angles are also called angle irons, steel angles, L-brackets, steel sections, or angle sections. They are a hot rolled high strength low alloy product that are often applied for reinforcement and building fixtures to fortify corners. They have a complete size range of 3/4″ x 3/4″ x 1/8″ – 2-1/2″ x 2-1/2″ x 1/2″ and structural angles are available in sizes ranging from 3″ x 2″ x 3/16″ to 8″ x 8″ x 1-1/8″.

  • What is the difference between structural channels and mc channels?


    MC channels have legs that are usually of equal thicknesses and structural channels have legs that taper. Structural channels are usually hot rolled and MC channels are usually fused.

    They are also available in different size ranges. MC channels are available in sizes 3″ x 7.1# – 18″ x 58.0#. And structural channels are available in sizes 3″ x 3.5# – 15″ x 50.0#.

  • Why does A529 show up so frequently in structural steel?


    A529 is a designated mild carbon structural steel grade. This grade meets particular mechanical properties. It is a popular choice in particular due to the exceptional combination of high strength, corrosion resistance, and ease of machinability
