Steel Joists

While decking forms the surface of your roof or floor system, steel joists serve as the structural framework underneath. These lightweight yet strong members offer exceptional load distribution and are designed to meet a variety of architectural and structural specifications. Triple-S Steel® supplies steel joists through our extended network to support fully integrated building systems. When combined with our decking, they deliver complete, code-compliant solutions for commercial and industrial structures.

Composite Deck

Composite steel deck merges the strength of steel with the versatility of concrete. These panels serve as both a working platform during construction and permanent structural reinforcement after the concrete pour. Triple-S Steel® provides high-quality composite deck profiles in a variety of gauges, profiles, and finishes.

  • Composite decking is ideal for:
  • Multi-story commercial structures
  • Medical and institutional buildings
  • Parking garages
  • Office towers and mixed-use developments

Benefits include fire resistance, reduced slab thickness, faster installation, and long-term structural performance.

Roof Deck

Steel roof decking is engineered to support roofing assemblies while offering excellent diaphragm shear and uplift resistance. Triple-S Steel® carries multiple roof deck profiles—including B-deck, N-deck, and A-deck—to meet architectural and load-bearing requirements.

  • Roof decking applications include:
  • Warehouses and industrial facilities
  • Retail and big-box buildings
  • Sports arenas and event centers
  • Government and defense projects

Our roof deck is available in galvanized or painted finishes and can be customized by length, profile, or coating to align with your project specs.
