| Weight per Foot | 1.043 lbs | 1.552 kg/m | ASTM A615 |
| Cross-Sectional Area | 0.31 in² | 200 mm² | ISO 3766 |
| Yield Strength | 60,000 psi | 420 MPa | BS 4449 |
Applications: Bridge decks, heavy machinery bases, seismic-resistant structures, and high-rise foundations.
Expert Commentary
Dr. Emily Carter, Structural Engineer:
*”#5 rebar’s 15.9mm diameter and 420 MPa yield strength strike a balance between load capacity and flexibility. For industrial floors or bridge foundations, it provides 30% higher tensile strength than #4 rebar, ensuring compliance with ASTM A615 standards. However, precise placement and 3-inch concrete cover are critical to prevent corrosion in ground-contact applications”.*
Prof. Zhang Li, Materials Engineer:
*”In seismic zones, #5 rebar’s ductility (minimum 12% elongation) prevents brittle failure during earthquakes. Pairing it with epoxy coatings extends its lifespan to 50+ years in corrosive environments”.*
