ASTM A992 Grade Reinforcing Bar #6 steel structural section is a high-performance steel member engineered for demanding structural applications requiring exceptional strength and reliability. Modern structural steel complies with ASTM A992 or equivalent specifications, providing minimum yield strength of 50 ksi with controlled chemical composition ensuring predictable material behavior.
This structural section provides optimal strength-to-weight ratio, enabling efficient long-span applications and reduced foundation loads. The rolled or fabricated profile distributes loads efficiently through carefully engineered flanges and webs. Reinforcing Bar #6 sections are preferred for applications requiring maximum moment resistance and lateral stability. Connections are designed using high-strength bolts (ASTM A325 or A490) or field welding with certified procedures ensuring joint strength exceeds member capacity.
Protective coatings are essential for long-term durability, typically involving shop-applied paint primer and field-applied finish coats, or hot-dip galvanizing for corrosion-prone environments. The material demonstrates excellent fatigue resistance when properly detailed, making it suitable for bridges, cranes, and structures experiencing cyclic loading. Fabrication requires certified welders following established codes and procedures. Quality control includes mill test reports certifying chemical composition and mechanical properties, with third-party inspection of critical welds.
Applications include building frames, bridge superstructures, industrial equipment supports, and transmission towers. Regional availability is excellent through established steel suppliers and fabricators. Cost reflects mill pricing, fabrication complexity, and protective coating systems. Sustainability considerations include recyclability and reuse potential at end-of-life, though initial embodied carbon is significant compared to other structural materials.
