More Details About Each Structural Steel Grade

  • A36

    A36 steel is a low-carbon grade of metal that is useful for most construction and civil engineering purposes. It is easy to weld, machine, and form. A36 steel is also one of the most commonly used grades of steel in part due to its low cost and wide applicability. 

    When fashioned into a beam, A36 steel features a tensile strength of 58-80 ksi and a yield point of 36 ksi. If galvanized, A36 steel can withstand extreme temperatures and other corrosive elements.

    Steel beams are measured in beam depth, flange width, flange thickness, web thickness, and fillet radius. At Kloeckner, we work with you to find the right-sized A36 beam for your project.

  • A992

    A992 steel may be the most commonly used grade of steel in construction projects. Small additions of copper, nickel, chrome, columbium, and molybdenum give this steel grade its clean definition.

    Grade A992 steel can be formed into a variety of shapes, including plates, channels, angles, I-beams, W-beams, and S-beams.

    With a tensile yield strength of 50 ksi and an ultimate strength of 65 ksi, A992 grade steel is mostly used in wide flange (W) beams.

  • A709-50

    The alloy that comprises A709-50 steel is designed for durability and corrosion resistance in outdoor settings. Iron, carbon, manganese, and other elements make it strong enough to use for bridges. A709-50 steel features a tensile strength of 65 ksi and a yield strength of 50 ksi.

    Manufacturers form this grade of steel into I-beams, structural angles, wide flange beams, and structural channels. Kloeckner Metals routinely stocks A709-50 beams in several different thicknesses, lengths, and widths.

  • A572-50

    A572-50 steel is an extremely strong grade that is quickly becoming popular for building and construction applications. This steel grade’s alloy includes manganese, silicon, phosphorus, sulfur, colombium, and vanadium. As a result of its chemical composition, A572-50 steel is highly corrosion resistant.

    This steel grade is extremely strong with a yield strength of 50 ksi and a tensile strength of 65 ksi. It can be used to form M, S, and W beams of various sizes. Often, these beams are used in constructing bridges and support structures in manufacturing plants.

    Due to its impressive strength, this grade of steel offers a thinner, more aesthetic alternative to A36 grade steel structural shapes.

  • A529-50

    An alloy composed mainly of manganese, phosphorus, silicon, sulfur, and carbon, A529-50 steel also contains 0.2% copper to help provide corrosion resistance. It is a particularly strong steel as well as a material that’s easy to weld, bolt, rivet, machine, and fabricate.

    A529-50 steel can be shaped into plates, bars, or other steel structural shapes. Due to its mix of strength, adaptability, and corrosion resistance, A529-50 steel is a popular choice for the structural components of bridges and high rise buildings.

General Info About Structurals

Structural steel is construction-grade metal that can support a heavy load without sagging or breaking.

Usually made from one of several grades of carbon steel, these structural shapes are strong, ductile, and easy to machine. Construction workers use them to fashion machine bases, bridges, parking garages, or commercial and residential buildings.

This steel comes in a variety of shapes and sizes, including several types of beams, plates, and channels.

Kloeckner Metals offers one of the largest inventories of steel plates in America. We are also one of the few steel fabrication companies that provides high-quality steel structural shapes, including PVQ, armored, and tempered plates.

Structural steel is typically available in grades A36, A992, A709, A572, and A529 steel.

Frequently Asked Questions

  • What do we mean by grades of steel?

    ANSWER:

    Different types of steel are graded — or organized — according to their chemical and physical properties. All grades of steel fall into one of four categories, carbon, alloy, stainless, or tool.

    Carbon steel is almost entirely composed of iron and carbon. Alloy steel contains additional elements such as nickel or copper. Stainless steel features a 10-20 percent chromium addition to its alloy, which gives it a bright appearance. And tool steel has a heat-resistant additive such as tungsten that makes it ideal for cutting. Most structural steel is carbon steel.

    Once it has been categorized, steel is assigned a letter and a number based on its strength, flexibility, and ability to withstand extreme temperatures, among other factors.

  • What are steel structural shapes?

    ANSWER:

    Structural steel is a category of steel for making construction materials. It can come in a variety of steel grades, including A36, A992, A709, A572, and A529. Each of these grades features its own distinct chemical structure and physical properties. In general, structural steel grades are strong, durable, and corrosion resistant. Often, they can be galvanized with a zinc coating. These grades are also easy to weld, rivet, bolt, machine, and fabricate. Structural steel can also take one of several shapes such as beams, bars, railes, channels, plates, and rods.

  • What are the most common structural shapes?

    ANSWER:

    Common structural steel shapes include beams, pipes, plates, and custom-designed shapes. Beams are among the most common shapes. These can include I-beams, which have two horizontal elements and a vertical element, along with S, L, H, C, and HSS shaped beams. S-beams have two parallel flanges connected by a web. L-beams feature two legs that join at a 90-degree angle. C-beams have a c-shaped cross section, and HSS beams have a hollow cross section.

  • What type of steel is used for structural shapes?

    ANSWER:

    Most structural steel is carbon steel although sometimes other elements are added to the alloy. The most common grades used for structural steel include A36, A992, A709, A572, and A529. Of these grades, A36 is the most widely employed. However, other materials may be more suitable for your project. Check with a steel manufacturing and fabrication expert before selecting a structural steel grade.
