From Columns to Purlins: The Science of Steel Choice in PEBs

Every great building starts with the right foundation—and in Pre-Engineered Buildings (PEBs), that foundation is steel. The type of steel you choose plays a major role in how safe, durable, and cost-efficient your structure will be over time. 
At Adoriva Infratech, we don’t believe in a “one-size-fits-all” approach. Every project has its own purpose, environment, and challenges—so we carefully select the right steel grade for each part of the building. This ensures your PEB not only performs well today but also stands strong for decades to come.  

Different Steels for Different Needs

Heavy Load Areas – 350 MPA Steel :
For primary structural members such as columns, rafters, and mezzanines, we rely on 350 MPA steel for its superior strength. Depending on thickness and environment, we choose sub-grades like E350BR, 350A, 350B0, or 350C. For example, in coastal or industrial areas, 350C offers added resistance to corrosion—making it ideal for tough conditions.  

Balanced Performance – 250 MPA Steel
For bracings, hot-rolled sections, and crane supports, 250 MPA steel provides the perfect balance of strength and flexibility. It keeps the structure stable while adapting to dynamic loads like wind and crane movement.  

Lightweight but Reliable – 250 MPA / 350A Steel :
For secondary members like purlins and girts, we use lighter steels such as 250 MPA or 350A. These grades are easy to shape and fabricate, yet strong enough to complement the main structure without adding unnecessary weight.  

Added Protection with Finishes
Every square foot counts in logistics. Strength is only half the story. To make sure your building performs well in the long run, we also apply protective finishes:

  • Galvanised Coating – Shields steel from rust and moisture.
  • Colour-Coated Finish – Enhances aesthetics while providing an extra layer of protection against UV rays and weather damage
    • This combination ensures your building looks good and stays durable for years. 

    Why the Right Steel Choice Matters :
    Choosing the right steel isn’t just about construction—it’s about confidence. Here’s what it guarantees:

  • Strength & Stability – Your building stands firm under heavy loads and daily use.
  • Long-Lasting Protection – Extra resistance against rust, corrosion, and tough climates.
  • Smart Investment – Reduces material wastage, avoids unnecessary costs, and delivers real value.
  • Future-Ready Design – Extends building life, lowers repair needs, and conserves resources.
    • At Adoriva Infratech, we don’t just build PEBs—we build trust. Every project is designed with precision, engineered with the right materials, and executed with quality you can rely on. Whether it’s an industrial shed, a warehouse, or a multi-level facility, our buildings are strong, sustainable, and built for the future. .
