December 11, 2025
Strong and durable structural steel beams from Scarboro Steel Works Inc. in Scarborough, Ontario.

In the commercial construction industry, material choice plays a major role in defining the efficiency, durability, and long-term performance of a structure. Engineers and contractors need solutions that can support large spans, withstand heavy loads and remain strong with minimal maintenance. This is where structural steel comes into the picture. 

They are the most preferred material of choice for business complexes and industrial plants, as well as retail centres and institutional buildings. Scarboro Steelworks Inc. has been one of the top steel beam suppliers in Ontario for 75 years. Today, we bring you a detailed blog on the role of structural steel in commercial projects

 

What is Structural Steel and Why is it Used for Commercial Projects?

Structural steel is a specifically engineered steel valued for its high strength-to-weight ratio. It forms the backbone of major load-bearing components, such as:

  • Beams and columns
  • Floor and roof systems
  • Bridges and large spans
  • Industrial mezzanines and platforms
  • Staircases and support structures

Why Is Structural Steel the Preferred Option in Commercial Construction?

  • Superior Strength-to-Weight Ratio: Structural steel handles high loads efficiently without adding extra mass.
  • Construction Speed: Prefabricated steel components accelerate project timelines and reduce on-site labour.
  • Design Flexibility: It can be shaped and fabricated into complex forms, supporting innovative architecture.
  • Durability and Fire Resistance: Structural steel withstands harsh environments and can be treated for added fire protection.
  • Sustainability: Steel is 100% recyclable, making it one of the most environmentally conscious building materials.
