Composition of Structural Steel

structural steel beams and girders in the framework of a buildingStructural steel is a versatile material that offers impressive yield and tensile strength without extreme weight. Combine this quality with easy machinability, and it’s easy to see why this material is used in just about every type of structure, including buildings, bridges, and ships. So, how is structural steel able to combine extra strength with low weight? It all boils down to its chemical makeup. Let’s take a closer look at the composition of structural steel.

A Versatile Alloy

Structural steel is an alloy comprising a variety of other elements, such as carbon, manganese, phosphorus, sulfur, and silicone. The amount of these sub-elements that are present in structural steel can vary depending on the application of the material. Different grades of structural steel are regulated by the American Society for Testing and Materials (ASTM), with the two most popular being A36 and A572. (Europe and Canada have their own standards for structural steel grades.) Here is a chemical breakdown of A36 and A572 structural steel grades:

  • A36 structural steel
    • 25-0.29% carbon
    • 03% manganese
    • 04% phosphorus
    • 05% sulfur
    • 28% silicone
  • A572 structural steel
    • 18-0.23% carbon
    • 5-0.7% manganese
    • 035% (max) phosphorus
    • 04% (max) sulfur
    • 150-0.3% silicone

Structural Steel and Plate Fabrication

The medley of chemicals that make up structural steel gives the material its strength and also makes it easy to fabricate. Structural steel beams and plates are typically fabricated using a CNC plasma cutting machine, a powerful tool that helps professional fabricators produce perfect products that will be used in the construction of a new structure.

The Most Advanced CNC Plasma Cutting Technology on the Market

Structural steel and plate fabrication companies that are looking to get ahead of their competition with better quality products and faster turnarounds rely on the power of BeamCut—the industry’s most advanced CNC plasma cutting system. This remarkable technology is equipped with state-of-the-art features, such as:

  • FANUC robotics – The six-axis FANUC robotic arm can bevel 360 degrees and process nearly any shape or profile required by the blueprints.
  • X-Definition plasma – Hypertherm’s X-Definition plasma system is one of the most powerful of its kind.
  • User-friendly CNC software – BeamCut’s CNC software is a cinch to use, comes fully stocked with a shapes library, and perfects the cutting process by eliminating mistakes in the design before the work begins.

Benefits of BeamCut

Thanks to BeamCut’s automated operations, structural steel and plate fabrication shops are able to keep operating costs in check. That’s because, with the advanced robotics doing the cutting, BeamCut eliminates cutting mistakes caused by the imperfect process of cutting by hand, preventing wasted costs on damaged materials. Automation also means that BeamCut only requires one technician to operate, which can save on labor costs. Furthermore, automated processing allows professional fabricators to speed up production time at their shop, helping them meet on-time deliveries and keep their customers happy.
