How Do Manufacturers Rate Structural Steel Beams?

July 09, 2021

Every fabricator knows that excellent engineering has to make proper use of exact measurements and load-bearing testing. When it comes to the manufacturing of structural steel beams, there are safety and quality standards that have to be strictly adhered to in order to ensure all products have consistent and reliable quality. 


Here are how structural steel beams are rated:


Structural Steel Standards


The global market uses various standards for rating structural steel beams. Here are two of the most prominent international standards:


  • American Society for Testing and Materials (ASTM): ASTM A283C
  • European Union (EU) S325


In Canada, the standards employed by manufacturers are equivalent to some of these international standards.  For example, Canada's W250X33 flange I-beam specifications are equivalent to the US' W10X22. Both have the same requirements and specifications but use different measurement systems, as Canada uses the metric system. When exporting Canadian-manufactured structural steel beams, manufacturers make sure they comply with the destination country's standards.


Types of Structural Steel Beams in the Market


With standards established, here are the most common types of steel beams that are manufactured for the market:


  • I-Beams: Resemble an "I" with cross-sections
  • HP Beams: Appear like an "H" due to their cross-sections
  • C Beams: Possess a "C"-shaped cross-section
  • Angle Beams: Have an L-shaped cross-section


Upgrades and Resistances


Lastly, manufacturers will indicate if their products have particular life-extending upgrades and resistances. Here are the various types of resistances most manufacturers add to their products:


  • Corrosion resistance
  • Additional flange welding
  • Cellular beams
  • Powder coating
  • Acrylic coating
