STEEL TRUSSES: An Overview

The Evolution of Trusses: Why Square Tube Steel Trusses Are Superior

When it comes to building strong, long-lasting roof structures, roof trusses are essential. From agricultural buildings to barndominiums and lean-tos, the right truss system makes all the difference. In this post, we explore the history of the truss, how trusses have evolved over time, and why steel trusses—especially Blackwater Truss Systems’ square tube steel trusses—are now the superior choice.

What Is a Truss?

A truss is a structural framework built primarily from triangles. This geometric design helps evenly distribute weight, allowing trusses to span large distances while maintaining strength and stability. Trusses are the go-to solution for roof support systems in everything from barns to barndos and metal buildings.

A Brief History of Roof Trusses

Trusses have been used for centuries—dating back to ancient Greek and Roman architecture. In the Middle Ages, timber trusses were commonly used in cathedrals. By the 19th century, wood trusses became standard in residential buildings. However, as the demands of modern construction grew, especially for larger and open-span buildings, wood fell short. The rise of metal and, more recently, steel roof trusses, provided a stronger, longer-lasting alternative.

Wood vs. Steel Trusses: What's the Difference?

Feature Wood Trusses Steel Trusses
Strength Prone to sagging and decay High strength-to-weight ratio
Durability Susceptible to rot and pests Weather- and insect-resistant
Fire Resistance Combustible Non-combustible
Lifespan 15–30 years 50+ years
Span Capabilities Limited Wide-span designs

Why Choose Square Tube Steel Trusses?

At Blackwater Truss Systems, we fabricate square tube steel trusses engineered for superior strength and clean aesthetics. Square tubing offers more stability than angle iron and allows for custom designs that fit your building’s needs exactly.

Our trusses are:

  • Custom-built for your project
  • Powder-coated or galvanized for corrosion resistance
  • Engineered for fast, easy installation
  • Ideal for barndominiums, pole barns, lean-tos, and garages

Steel Trusses for Modern Roof Construction

Using steel trusses allows for:

  • Fewer interior supports (open floor plans)
  • Faster build times with prefabricated components
  • Lower maintenance and lifetime costs
  • Improved performance under heavy wind and snow loads

Conclusion

The truss has come a long way—from hand-hewn wood to today’s advanced steel structures. If you’re planning your next building project, don’t settle for outdated materials. Choose the unmatched reliability and strength of square tube steel trusses from Blackwater Truss Systems.
